Overview

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  
DIP-switches to determine the serial port baud rate (see Section 6.3)  
In Hardware mode, the:  
VP-14xl routes the reply from the output port defined by the DIP-switches 2,  
3 and 4 (see Section 6.2)  
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  
inputs (RS-232, RS-485 or USB), see Section 8.  
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

Figure 2: Connecting the VP-14xl RS-232 Port Extender  
To connect your VP-14xl RS-232 Port Extender, as the example in Figure 2  
illustrates1:  
1. Connect up to three computer sources to the input connectors (for example, 2  
PCs and a laptop).  
2. Connect up to three units to be controlled to the output connectors (for  
example, Kramer switches).  
3. If you are using the RS-485 input, set the RS-485 termination (see  
Section 6.1).  
1 Switch OFF the power on each device before connecting it to your VP-14xl. After powering up your VP-14xl, switch on the power to  
each device

Setting the DIP-switches on the VP-14xl  
4. Set the Hardware/Software DIP-switch (see Section 6.4) as follows:  
.
In Hardware mode, set the REPLY DIP-switches to determine the unique  
reply output port (see Section 6.2)  
.
In Software mode, set the machine number (see Section 6.2).  
5. Set the serial port baud rate (see Section 6.3).  
6. Select the appropriate machine number (see Section 6.2).  
7. Connect the 5V DC power adapter to the 5V DC socket and to the mains  
electricity.  
Note: Changing any DIP-switch requires that you either power cycle  
the VP-14xl or press the Reset button (see Table 1).

Technical Specifications  
6.5 Hardware Mode  
In Hardware mode, the:  
RS-232 data is passed from any input to all outputs  
VP-14xl routes the reply from the output port defined by the DIP-switches 2,  
3 and 4 (see Section 6.2). For reliable operation, only one port should be  
defined  
6.6 Software Mode  
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  
inputs (RS-232, RS-485 or USB), see Section 8.  
Note: Only one reply port can be opened at a time. It is possible to open multiple  
direct ports but only one reply port can be open at a time.  
This means that if port1 is currently open and you then open port2, the port 1 is  
automatically closed. If you then open port 1 again, port 2 is automatically closed.  
In this way it is possible to close all reply ports, as well as all direct ports.

Table of Hex Codes for Serial Communication (Protocol 2000)  
The RS-232/RS-485 Protocol 2000 uses four bytes of information as shown in  
Table 8. The data rate is set by the DIP-switches (see Table 5), with no parity, 8  
data bits and 1 stop bit.

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.  
9
 
       
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.
