Overview
The unique VP-14xl RS-232 Port Extender distributes an incoming RS-232,
RS-485 or USB command as transmitted by a touch screen control system,
personal computer or other type of control system, to up to three RS-232 ports.
This lets you control up to three compatible devices with only one serial port or
RS-232 card.
The VP-14xl is specifically designed for use with Kramer switchers and routers,
but can be used with any other equipment which employs RS-232.
In particular, the VP-14xl features:
•
•
•
•
•
•
One RS-232 input port
One RS-485 input port
One USB input port
Three RS-232 output ports
Operation in either Hardware or Software mode
DIP-switches to determine the source of the reply command when the
VP-14xl is in hardware mode
•
DIP-switches to determine the machine number when operating in Software
mode and there are multiple VP-14xl units on the RS-485 bus
•
In Hardware mode, the:
•
VP-14xl routes the reply from the output port defined by the DIP-switches 2,
•
RS-232 data is passed from any input to all outputs
In Software mode, the VP-14xl routes the data and reply based on the Protocol
2000 commands received from the PC or other device connected to any of the
To achieve the best performance, we recommend:
•
Connecting only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
•
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your VP-14xl in a location
free from moisture and away from excessive sunlight and dust
Caution:
No operator serviceable parts inside the unit
!
Warning: Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning: Disconnect the power and unplug the unit from the wall
before installing

1st BYTE:
Bit 7 – Defined as 0.
D – “DESTINATION”:
0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher).
N5…N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is performed via the
machine’s keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The instruction codes are defined according to the
table below (INSTRUCTION NO. is the value to be set for N5…N0).
2nd BYTE:
Bit 7 – Defined as 1.
I6…I0 – “INPUT”.
When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched. Similarly, if switching is done
via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was switched. For other operations, these bits are defined
according to the table.
3rd BYTE:
Bit 7 – Defined as 1.

Table of Hex Codes for Serial Communication (Protocol 2000)
O6…O0 – “OUTPUT”.
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if switching is
done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was switched. For other operations, these bits are
defined according to the table.
4th BYTE:
Bit 7 – Defined as 1.
Bit 5 – Don’t care.
OVR – Machine number override.
M4…M0 – MACHINE NUMBER.
Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually
configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept
(implement) the command, and the addressed machine will reply.
For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE
NUMBER = 1.

INSTRUCTION
DESCRIPTION
DEFINITION FOR SPECIFIC INSTRUCTION
INPUT OUTPUT
0–close
1–open
NOTE
#
2C CONTROLS THE STATUS OF A
PORT
Output bit:
O0–O5 = output # or 0 for all outputs
O6–0 = Tx; 1 = Rx
1, 2, 4, 5
2D READS THE STATUS OF A PORT 0–open
Note: All values in the table are hexadecimal, unless otherwise stated.
Output bit:
O0–O5 = output #
O6–0 = Tx; 1 = Rx
2, 3, 4, 5
NOTE 1 – When the PC sends this command, if the instruction is valid the unit replies by sending the PC the same 4 bytes that it was sent (except
for the first byte where the Destination bit is set high).
NOTE 2 – If O6 = 0 (Tx) – This command defines/reads the definition of the output # (1, 2 or3) to pass the RS-232/Direct command from any
input. In this case the instruction does not modify previously set output numbers, allowing the setting of multiple outputs for the Direct command. If
O6 = 1 (Rx), the command defines/reads the definition of the output # (1, 2 or 3) to pass the reply from the output to inputs. In this case, the
instruction resets a previously set output number, preventing the setting of multiple outputs for the reply.
NOTE 3 – The reply to this command is as follows: The same command and output codes as were sent are returned, and the input is assigned the
value of the parameter that was read. The reply is per the definitions in command 44.
NOTE 4 – At initial power-on or on reception of command 44 or 45, any received bytes are analyzed to see whether it is a command 44 or 45. If
not, it is transmitted to the output based on the existing setup. If the analyzed bytes are a command 44 or 45, the unit waits for the other 3 bytes and
interprets them as a Protocol 2000 command. The command is executed if relevant to this machine number or discarded if not.
NOTE 5 – This command works only when the unit is configured for Software mode.
