1.2 UDAS 1001E Series Functional Description
This section provides information on the following data acquisition functions:
•
•
•
•
Analog input
High-speed analog input
Acquisition pacing and triggering
Power supplied by the USB port or by an external power supply
1.2.1 Da ta Acquisition Functions
Ana log Input
The A/D converter on the UDAS device is a 12-bit converter with a throughput rate of 100 kHz.
For analog input:
•
Programmable input voltage ranges are 0-10 V, ±5 V, and ±10 V.
1-4
•
•
Programmable gains are 1, 10, and 100 which translate to a full-scale input of 0-10 V, 0-1.0 V,
0-0.1 V, ±10 V, ±1.0 V, ±0.1 V, ±5 V, ±0.5 V, and ±0.05 V.
The analog input section has 16 single-ended or 8-differential analog input channels.
The analog input section has a first-in-first-out (FIFO) buffer for high-speed capturing of data up
to 100 kHz.
An analog trigger is also provided to initiate high-speed conversions based on a voltage transition
on a selected analog input channel, or on an external TTL level signal. A programmable crystal-
based rate generator regulates high-speed conversions.
High-Spe e d Ana log Input Mode
High-speed mode uses the rate generator (described below), or an external input to start data
conversions. The use of the rate generator or an external signal to start conversions is referred to
as pacing.
On the UDAS unit, the rate generator is able to provide rates from 0.477 conversions per second
to 100,000 conversions per second. These conversions are either performed on a single input
channel, or performed on a range of input channels by using the channel scanner (described
below).
When the conversion is complete on the current channel, the channel scanner automatically
selects the next channel. The term high-speed refers to the use of pacing to automatically begin
the conversions. The speed of the actual rate of conversions can be controlled by using the rate
generator. See Rate Generator, on page 1-6.
Sta rting a nd Stopping the High-Spe e d Ana log Input Mode
There are several methods to start and stop conversions available on the UDAS:
•
•
•
•
•
Start with trigger, Stop with software
Start with trigger, Stop after N samples
Start with software, Stop N samples after trigger
Start with software, Stop with software
Start with software, Stop after N samples
Starting Conversions
To start the conversions, use either a trigger or a software command. The trigger can be an
external digital TTL level input, or an analog input. For an external TTL signal, the slope (rising
edge or falling edge) must be specified. Use the external input pin to provide this input.
1-5
UDAS-1001E Series Data Acquisition Systems
If an analog input is used for the trigger, specify the trigger level, analog input channel, and
slope. Use analog output channel 1 for setting the trigger level.
Note: When using analog input channel 1 for a trigger, do not use this channel
for any other purpose.
When an input signal on the selected channel of the proper slope (rising or falling voltage) crosses
the trigger level, the conversion process begins.
Stopping Conversions
To stop a conversion, use either a software command, an N samples counter, or a combination of a
trigger and an N samples counter.
Use the N samples counter to specify the number of samples that you want to capture.
When the trigger is used to stop a conversion, and the N samples counter is used, a post-
triggering function occurs. In this mode, software is used to start conversions and continue
indefinitely until a trigger event occurs. When a trigger event occurs, N additional samples are
captured.
Ra te Ge ne ra tor
The UDAS unit contains an on-board 24-bit rate generator for analog input pacing. The base clock
for the rate generator is an 8 MHz clock derived from a crystal which provides 125 ns resolution
and a frequency range of 0.4768371 Hz to 4 MHz.
The I/O connector has a rate generator output pin that is driven by either the Analog Input Rate
Generator or the Analog Output Rate Generator.
Cha nne l Sca nne r
When the channel scanner is enabled, immediately after the conversion on the current channel
finishes, the next analog input channel to be converted is automatically selected.
The UDAS device incorporates a 0 to N scanner. This allows analog conversions on all of the input
channels from channel 0 to channel N, where the value of N is programmable.
The scanner selects each channel for conversion, beginning with channel 0, incrementing to
channel N. After the conversion on channel N is complete, the scanner selects channel 0 and the
process repeats.
1-6
The scanner operates with the built-in analog channels, or with the optional AI-MAX. The AI-
MAX allows up to 256 analog input channels to be connected to a single UDAS device.
Note: The scanner begins on the selected trigger channel and not channel 0 when the
start on trigger mode is used with an analog input trigger.
High-Spe e d Ana log Input Trigge ring
To start or stop conversions, use triggering in the High-Speed Analog Input mode in the UDAS
device. The trigger signal can be either an analog input or a digital input.
When using an analog input as the trigger, the start on trigger mode causes the scanner to start
on the trigger channel. For example, if the trigger channel is set to 5, the N channel of the 0 to N
scanner is set to 7, the return data is as follows:
channel 5
channel 6
channel 7
channel 0
channel 1
...
channel 7
channel 0
...
When using the stop on trigger mode and the trigger is from an analog input channel, the trigger
signal is sampled only when the trigger channel is the active scanner channel. Although this
allows any channel to be used for triggering, it imposes some restrictions on the characteristic of
the trigger signal.
The duration of the trigger signal must be long enough to cause the unit to trigger. Use the
following formula to calculate the length of a signal to ensure that the signal is long enough to
activate the trigger: (Total channels scanned)/(scan rate in Hz).
1-7
UDAS-1001E Series Data Acquisition Systems
Example:
If 9 channels are being scanned at a rate of 100Hz and the slope is low to high, the trigger signal
must remain below the trigger level for 9/100 of a second, and above the trigger level for 9/100 of a
second to ensure that a trigger event occurs. When using External Input as the trigger, this
restriction does not apply.
When using an analog input channel for triggering, analog output channel 1 is used to set the
trigger level.
Note: Do not use analog output channel 1 for any other purpose while analog
triggering is in use.
Due to the internal configuration of the unit, the voltage appears on the analog output 1 pin as
the negative value of the desired trigger voltage. Connecting this pin to another signal, or
shorting it out causes the trigger voltage to be incorrect.
Auto Ze ro
When in auto zero mode, the inputs to the Analog input circuit are internally grounded, disabling
the input multiplexers. This enables a known 0 volt signal to be measured, and the value read can
be used to compensate for input offset errors.
Ana log Output
The UDAS device has two analog output channels. Each output channel has 12-bit resolution and
a ±10 V output range. A FIFO is available for waveform generation.
This FIFO can be used as a circular buffer for either or both analog output channels to allow
repetitive waveform generation and supports waveforms of up to 512 points (single channel) or
256 points (dual channel). The unit also supports non-repetitive wave forms.
When the unit is powered-on and the analog outputs are not enabled, the output voltage is 0 V.
This provides a known voltage when the UDAS unit is powered-up.
Analog output channel 1 is also used to support the analog trigger function for hardware-paced
analog input conversions (as described above).
Digital I/ O
The digital data acquisition circuit consists of two 8-bit digital I/O ports providing 16 digital I/O
bits and one 32-bit counter. Output power-on states are configured for Port 1 through an internal
DIP switch. The digital I/O is configured as 2 ports (0 and 1) of eight bits each.
1-8
Digital I/O signals are TTL-compatible and perform functions such as reading digital inputs,
driving digital outputs, and detecting input change-of-state.
Digital I/O direction is programmable separately for each port through software. A nine-position
DIP switch is provided inside of the unit to select the power-up direction of Digital I/O Port 1
(input/output) and to individually set power-up output states for each bit.
Counte rs
One counter input line is connected to a 32-bit counter for high-speed counting (up to 2 MHz).
This counter supports event counting and frequency measurement.
An event counter counts pulses occurring at its input. For frequency measurement mode, the
pulses are captured over an internally generated gate time. The frequency is calculated from the
captured count and the gate time. The gate time can be set to 1ms, 10ms, 100ms, or 1s through
software.
Term ination
The UDAS unit provides the user with several options for connecting to I/O signals. You can use a
50-pin ribbon cable to connect signals directly to the UDAS unit.
There are many termination products available from Intelligent Instrumentation with a 50-pin
interface. See our catalog for a variety of termination options. For the UDAS-1001E-3 and UDAS-
1001E-4 models, use the built-in termination to connect signals directly to the unit.
The built-in termination panel is directly mounted to the back plate of the UDAS unit, providing
easy access to all I/O signals (FIGURE 1.2, UDAS-1001E-4 dimensional drawing). The
connections are made using pluggable 5mm terminal strips to simplify the wiring. A cold junction
compensation circuit (CJC) is incorporated on the board to allow the use of thermocouples.
To use the CJC circuit, you must enable it by setting the jumpers. The jumpers are located on the
back side of the termination panel and require removal of the panel to gain access. For
information on the jumpers, reference Chapter 2, Configuration and Installation, and see TABLE
2.1, CJC Jumper Positions.
Note: When the CJC is enabled, differential channel 0 is used. Do not connect
anything to Analog Input 0 or Analog Input 8.

1.2.2 Powe r
The UDAS unit normally uses power from the host computer via the USB cable. Power can also be
obtained from an external power supply that is available (See Appendix B, Accessories). When the
UDAS unit is connected to a power source, the computer controls the power. The unit does not
have a power switch. There is an LED labeled PWR located on the front panel that indicates
power to the unit, regardless of its source.
The USB specification imposes strict requirements on power usage. If an external power supply is
used, up to 200 mA at +5 VDC is available to external termination circuits (available at pin-26
and pin-48 of the unit’s 50-pin I/O connector).
See section 1.3, Software Support and Accessories or Appendix B,Accessories for the part numbers
of the available Power Adapters. If the power is supplied from the PC through the USB port, care
must be taken to limit the load from the external termination panel to less than 20 mA.

Configuration and
Installation
2.1 Introduction
This chapter contains instructions on the configuration and installation of the UDAS unit.
2.2 Power-on Default Digital I/ O Configuration
In some situations, it is important to have the digital output port on a UDAS unit initialize at
power-on to a particular state. For example, if the digital output port controls a piece of
mechanical equipment, safety regulations may require the digital output port bits to have values
of 0000 0011 when power is first applied. Port 1 on the UDAS unit provides the ability to set the
power-on direction to output and the states of all of the bits. A switch block located on the main
board of the UDAS unit accomplishes this task. Since the default switch states configure the port
for input, you may not need to change the switch settings.
This section contains instructions for setting the power-on default Digital I/O configuration, if
applicable.
CAUTION:
Use proper static-sensitive device handling procedures (such as the use of grounded
wrist-strap) when opening the unit, as damage to the equipment may occur.
Re m oving the Cove r
1. Unplug the power supply to the UDAS unit.
2. Using a Phillips head screwdriver, remove the two Phillips head screws on the front face plate
of the UDAS unit I/O cover. The front face plate contains the power and status indicators and
the USB connector.
3. Carefully separate the face plate from the cover.
4. Slide the cover towards the open end of the unit to free it from the back termination plate,
removing the cover from the UDAS unit.
2-1
Configuration and Installation
Se tting the Configura tion
Switches 1-8 set the initial levels of the port’s channels 0-7 if the port is set for output operation.
A switch set to the On position sets the corresponding port’s output channel to a high level (TTL
+5V) on power-up.

If you plan to use any of the digital I/O ports for output control in your application(s), note the
following Caution statement:
CAUTION:
For applications using UDAS units to generate output signals for control or other
sensitive purposes, the status or level of outputs during power-up may be of critical
importance. Integrated circuits and other devices powered by supply voltages are
subject to possible transients or an indeterminate status while the power supply
voltages are making the transition from zero to their steady-state values.
Locate switch S1 shown in FIGURE 2.1, UDAS Switch S1 in the lower left-hand corner of the
board.
1. Set the direction for Port 1. The default setting is input (Off).
To designate Port 1 as an output port: set switch 9 to the On position.
To designate Port 1 as an input port: set switch 9 to the Off position.
2. To set the initial data for Port 1, set switches 1-8.
On = 5 V
Off = 0 V
Note: You can reconfigure any of the ports through software after the unit is
powered-up. Port 0 always powers-up as an input port.
Re insta lling the Cove r
1. Insert the cover onto the rails located on both sides of the base of the UDAS unit and slide the
cover towards the back panel until the cover is seated into the frame on the back panel.
2. Place the face plate over the edges of the cover and unit’s frame.
3. Align the screw holes on the cover with the unit, insert each Phillips screw on the face plate
and tighten the screws into place.
Enabling the CJC
To enable the CJC:
•
Install jumpers A, C and D on JP1.
The CJC circuit uses differential channel 0 to report compensation information to the UDAS.
When using the CJC circuit, verify there is no external signal connected to channel 0/8.
2-3
Configuration and Installation
Channels connected to a thermocouple must be connected to bias resistors for proper operation.
Use jumpers JP2 and JP3.
Note: When monitoring thermocouples, always use differential channels.

Checking the System
3.1 Introduction
This chapter contains instructions for installing and using the UDAS SYSCHECK software. The
software contains diagnostic features that verify the UDAS unit is functioning.
WARNING!
Use extreme caution when using SYSCHECK.
The UDAS SYSCHECK software could cause unexpected results in the equipment that you
connect to the UDAS unit.
Depending on the type of equipment that you have connected to the UDAS unit, severe
damage to equipment and/or bodily harm may occur while conditions of the UDAS are in
transition.
Large unisolated voltages may damage the UDAS unit. UDAS analog output will not drive low
impedance loads.
The UDAS digital I/O inputs and outputs must be TTL compliant.
UDAS analog inputs in excess of 20 V may cause permanent damage to the UDAS unit.
UDAS counter inputs must be TTL compliant.
SYSCHECK is only an interface to the UDAS unit(s). The way that you interface input or outputs
to the UDAS can be a complicated issue.
Since a variety of termination panels are available for the UDAS units, refer to the
documentation provided with the termination panel for the exact I/O configuration of the specific
panel that you purchased.
Termination options are discussed in Appendix B, Accessories in this manual.

B.1.3 Isola tor Blocks
PCI-1100 Series Digita l Opto-Isola tor Blocks
The PCI-1100 Series are digital, optically isolated, signal conditioning blocks. A separate opto-
block is used for each channel, allowing complete I/O flexibility.
The twelve different opto-blocks are divided into two groups: standard and slim-line.
Both standard and slim-line models can be used on EDAS-1011T-1 Panels.
•
Only standard models (PCI-1101 through PCI-1106) can be used with the PCI-20018T-1 and
PCI-20048T-1 termination panels.
•
Only slimline models, PCI-1107 through PCI-1112, can be used with 3U sized termination
panels (PCI-20324T-1 and PCI-20326T-1).
Summary of Features
•
•
•
•
All input models accept both AC and DC voltages.
Each provides a TTL output to drive a standard digital input.
Different models are provided for AC and DC outputs.
Units convert TTL outputs from the data acquisition system to switch higher voltage and
current loads.
•
•
•
DC output devices present an open collector NPN transistor to the load.
AC output units contain zero crossing circuitry and switch their loads with triacs.
All models provide 4000 V isolation input to output.
Various combinations of the available opto-blocks can be intermixed on one termination panel.
Each contiguous group of eight channels must contain only input or output opto-blocks since the
digital channels on the Digital I/O UDAS are programmable as inputs or outputs in byte-size (8
bits) units.

Calibration Procedures
C.1 UDAS Analog Input Circuit Calibration
Procedures
The analog input section of each UDAS unit is calibrated at the factory prior to shipment. If your
application requires periodic calibration checks or if inaccuracies occur, use the procedures below
to calibrate the UDAS unit. This calibration is accomplished by the adjustment of potentiometers
on the UDAS unit’s printed circuit board.
This calibration procedure requires the utility software provided with the unit, or some other
software such as Visual Designer for displaying the Analog to Digital converter (A/D) results in
counts format and for setting required gains and ranges.

C.1.2 Ana log Input Ca libra tion Procedure
Calibrating the analog input section requires adjusting the input offset voltage, the ± 10V range,
± 5V range, and the 0 to 10V range. The procedures are listed separately, but should be performed
during a single calibration session.
Note: The input offset voltage must be adjusted and in specified limits beforethe other
adjustments are performed.
Adjust Input Offset Voltage
1. Attach the termination panel to 50-pin connector of UDAS, unless the unit has built-in termi-
nation.
2. Ground analog input channel 0 to analog ground, not digital ground, on the termination panel.
3. Connect a precision voltmeter between TP27 and analog ground, TP21.
4. Run a program, such as SYSCHECK, to configure the UDAS for single-ended operation,
bipolar input (±10 V) and a gain of 1.
5. Read the voltage from the voltmeter.
6. Reconfigure the UDAS for a gain of 100. Adjust R58 so that the offset voltage read from the
voltmeter is equal to the voltage read in step 4.
7. Repeat steps 4 and 5 to minimize the offset difference observed between the two gain settings.
The offset difference observed between the two gain settings should be within ±0.5 mV. If pos-
sible, try to achieve less than ±0.2 mV offset difference.
8. Reconfigure the UDAS to a gain of 10 and verify the offset value is less than 0.5 mV different
from the last value read at a gain of 1.
Adjust Offse t a nd Ga in for ± 10Volt Input Ra nge
1. Verify the termination panel is attached to the 50-pin connector of the UDAS device. Begin
with step 2 if the unit has built-in termination.
2. Attach a voltage calibrator to channel 0 with all of the other channels grounded.
3. Run a program, such as SYSCHECK, to configure the UDAS for a range of ±10 V and gain of 1.
4. Set the calibrated input to 0 V, or short channel 0 to analog ground.
5. Set SYSCHECK or other program to average 50 readings. Manually or automatically take
readings repeatedly.
6. Adjust Pot R51 until the software displays 0 V.
C-3
Analog Input and Output Calibration Procedures
.
Note: On all adjustments, there is likely a range of adjustment resulting in the proper
reading. Determine this range and leave the adjustment in the center of the range.
7. Set the calibrated input to 9.5068 V.
8. Adjust Pot R46 for 9.5068 V.
9. Repeat the procedure and verify the adjustments are correct.
Note: These adjustment steps are interactive and may require several iterations.
10. Set the precision voltage source to -9.95117 V and check for a reading of -9.95117.
Note: If the value you read is more than 0.039 V different from -9.95117, then the
following Alternate Bipolar Calibration must be used.
Adjust Offse t a nd Ga in for ± 5Volt Input Ra nge
1. Verify the termination panel is connected to a 50-pin connector of the UDAS unit. Begin with
step 2 if the unit has built-in termination.
2. Attach a voltage calibrator to channel 0 with all other channels grounded.
3. Run a program, such as SYSCHECK, to configure the UDAS for a range of ±5 V and gain of 1.
4. Set calibrated input to 0 V, or short channel 0 to analog ground.
5. Set SYSCHECK or other program to average 50 readings. Manually or automatically take
readings repeatedly.
6. Adjust Pot R39 until the software displays 0 V.
Note: On all adjustments there will be a range of adjustment that results in the proper
reading. Determine this range and leave the adjustment in the center of the range.
7. Set the calibrated input to 4.5734 V.
8. Adjust Pot R40 for 4.5734 V.
C-4
9. Repeat the procedure and verify the adjustments are correct.
Note: These adjustment steps are very interactive and may require
several iterations.
Adjust Offse t a nd Ga in for 0 to 10 Volt Ra nge
1. Verify the termination panel is attached to the 50-pin connector of a UDAS unit. Begin with
step 2 if the unit has built-in termination.
2. Attach a voltage calibrator to channel 0 with all of the other channels grounded.
3. Run a program to configure the UDAS for a range of 0-10 V and a gain of 1.
4. Set the calibrated input to 0.02441 V.
5. Set SYSCHECK or other program to average 50 readings. Manually or automatically take
readings repeatedly.
6. Adjust Pot R38 for 0.02441 V.
Note: On all adjustments there will be a range of adjustment that results in the proper
reading. Determine this range and leave the adjustment in the center of the range.
7. Set the calibrated input to 9.97558 V.
8. Adjust Pot R45 for 9.7558 V.
9. Repeat steps 4 through 8. There will be a very slight interaction in these adjustments.
10. After calibrating the unit, slide the unit’s cover back on and refasten the front panel using the
screws removed earlier.
