DESCRIPTION:
Functional Description
The CNTV, illustrated in figure 1, is part of the MRMT-21 RF Classroom System or may be used
separately as a Cresnet network device. Regardless of the system, the primary function of the CNTV is to
accept and process system commands to control televisions or other associated audio/video devices in a
remote location. The scope of this document provides technical information of the CNTV as a stand-alone
Cresnet network device. Refer to the latest revision of MRMT-21 (Doc. 5602) for operation of the unit
within the MRMT-21 system.
Physical Description
The CNTV is housed in a black enclosure with silk-screened labels on the front and back of the case. On
the front, there are five red LEDs for indicating the current status of the unit. All connections are made on
the back of the unit.
There are four rubber feet on the base of the unit for stability and to prevent slippage. If necessary, the
user can apply Dual Lock fasteners to the unit's underside. The rubber feet do not need to be removed. The
fasteners may be preferred for additional stability when mounting the unit onto the surface of a TV.

CONTROLS AND INDICATORS:
Controls
The CNTV has an IR receiver on the front-right side, located above the CNTV label. Verify that the receiver
is in a line-of-sight path and unobstructed. The LED flashes when IR is received, confirming a good line-of-
sight path.
CAUTION
Direct sunlight or other light sources may prevent the unit from working properly by
desensitizing the CNTV IR receiver.
All CNTVs contain an IR receiver port, two IR outputs, two power sensors, four VersiPorts, two serial
ports, and a CRESNET port. The IR receiver port receives signals from the MRHC transmitter. The two IR
outputs are designed to work with IR controlled devices including TVs and other classroom equipment.
The digital connector of the CNTV-CS (supplied) attaches to the DIGITAL IN/OUT back panel connector of
the CNTV. The CNTV-CS senses whether a single television set (9" color or larger) is OFF or ON. The
NET port is provided for connection to the Cresnet system. There are four bidirectional TTL lines (or
VersiPorts) on the unit which are capable of sensing TTL voltage levels, analog voltage levels, or contact
closures to ground. They can also output TTL/CMOS logic levels. These lines provide control or sensing of
additional classroom equipment (i.e., security systems).

Identity Code
The CNTV identity code (ID CODE) consists of a two-digit hexadecimal number. These codes are vital for
proper communication and typically factory set. An ID CODE label is affixed to each unit. The ID CODE can
range from 03 to FE. The ID CODE of each unit must match the ID CODE specified in the SIMPL Windows
program in order for the device to be addressed properly.
If the CNTV ID CODE needs to be altered, it can be set from a PC via CNTV SETUP menus. Refer to the
Appendix in this guide for details that describe the method of setting the CNTV ID CODE.
Power and IR Testing
Power and IR testing consists of equipment placement and running a software test. Placement of sensing
devices must be performed before running the software test. Make proper connections as shown in figure
4. Refer to the Appendix in this guide for details that describe how to run a power sensor test. If a wired
panel is employed, an abridged power sensor test consists of observing illumination of the "POWER" LED
while turning TV power on and off manually.
Power Sensor Placement
Use a CNTV-CS (supplied) or power sensor loop (optional) to detect power from television or other
equipment to be controlled. The CNTV-CS should be plugged into an AC outlet and the television to be
current sensed is plugged into the CNTV-CS. The digital connector of the CNTV-CS is attached to the
DIGITAL IN/OUT back panel connector of the CNTV. Alternatively, a wire loop (as shown in figure 3) can
be constructed and placed in the electromagnetic field of the television flyback transformer. Perform
Power Sensor Test (refer to Enter Test Menu in the Appendix of this guide) to determine if the device is
OFF or ON or in the electromagnetic field.
NOTE
The loop is less reliable than the CNTV-CS, since it depends heavily on position and
the low-power emissions of the television.

IR Probe Placement
Place a MRIRP over the IR window on a television or other equipment to be controlled. MRIRP must
completely cover IR window and other extraneous light should be blocked with opaque tape. Turn the TV
on manually. If the TV does not respond to "MUTE" or "VOLUME" commands from the transmitter or
wired panel, change the position of the MRIRP.
Preparation for Use
NOTE
The CNTV should be powered from a 12 VDC power pack. Obtaining power from the
power pack and the network does not result in damage to the unit. If system design
prevents use of power pack (i.e., absence of AC outlet) contact a Crestron technical
support representative for power alternatives.
Crestron recommends specific power packs for its network devices. The recommended power pack for
the CNTV is Crestron part number PW-1205. If an external power pack other than this Crestron model is
obtained, verify that it meets the required specifications and polarity as shown in table 3.

Refer to figure 5 for a typical hook-up diagram of the CNTV within a Cresnet system. Connecting cables
and hardware are not supplied with the unit, due to variations of installation requirements. Crestron
recommends that wall jacks with an RJ11 (6-6) receptacle be located in the room with a CNTV. Use a
telephone cable of appropriate length to connect the CNTV to the wall jack. Wire a Cresnet cable to the
four terminals at the rear of the wall jack.
CAUTION
The modular NET port on the CNTV requires unique wiring. Wiring the port according to
Crestron Network Modular Cable Requirements (latest version of Doc. 5682) will
result in damage to the CNTV.
Due to the wire order within the cable, the connecting color scheme is non-standard and illustrated in
Detail A of Figure 5. Local power is provided, so the fourth wire (+ 24V) is not needed. If a wall jack
connection is not an option, Detail A also illustrates a direct to Cresnet alternative. Detail B provides a
detailed illustration of the communication cable required if a wired panel is employed as an interface.
