5.1.1 Setting the Machine ID DIP-switches
The MACHINE ID determines the position of a VS-81HDxl unit, specifying which
VS-81HDxl unit is being controlled when several VS-81HDxl units connect to a PC
or serial controller. Set the Machine number on a VS-81HDxl unit via MACHINE ID
DIPs 1, 2, 3 and 4, according to the following table.
When using a standalone VS-81HDxl unit, set the Machine ID to 1. When
connecting more than one VS-81HDxl unit, set the first machine (the Master) that
is closest to the PC, as Machine ID 1 (the DIP-switches are set to OFF).
5.2 Connecting to the VS-81HDxl via RS-232
You can connect to the unit via a crossed RS-232 connection, using for example,
a PC. A crossed cable or null-modem is required as shown in method A and B
respectively. If a shielded cable is used, connect the shield to pin 5.
Method A (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note: There is no need to connect any other pins.

to PC
Null-Modem
Adapter
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
Method B (Figure 6)—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem
adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually
contains all nine wires for a full connection of the D-sub connector. Because the
null-modem adapter (which already includes the flow control jumpering described
in Method A above) only requires pins 2, 3 and 5 to be connected, you are free to
decide whether to connect only these 3 pins or all 9 pins.
Figure 6: Straight Cable RS-232 Connection with a Null Modem Adapter
5.3 Connecting a PC or Controller to the RS-485 Port
You can operate the VS-81HDxl via the RS-485 port from a distance of up to
1200m (3900ft) using any device equipped with an RS-485 port (for example, a
PC). For successful communication, you must set the RS-485 machine number
and bus termination.
To connect a device with a RS-485 port to the VS-81HDxl:
Connect the A (+) pin on the RS-485 port of the PC to the A (+) pin on the
RS-485 port on the rear panel of the VS-81HDxl
Connect the B (–) pin on the RS-485 port of the PC to the B (–) pin on the
RS-485 port on the rear panel of the VS-81HDxl
Connect the G pin on the RS-485 port of the PC to the G pin on the RS-485
port on the rear panel of the VS-81HDxl

8 Protocol 2000
This RS-232/RS-485 communication protocol uses four bytes of information as
defined below.
For RS-232, a null-modem connection between the machine and controller is
used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.
8.1 Syntax
1st Byte: Bit 7 – Defined as 0
The 6-bit INSTRUCTION defines the function performed by the switcher(s). If a function is performed using the
machine’s keyboard, these bits are set with the INSTRUCTION NO. performed. The instruction codes are defined
according to the table below (INSTRUCTION NO. is the value set in N5…N0).
2nd Byte: Bit 7 – Defined as 1
I6…I0 – INPUT
When switching (i.e. instruction codes 1 and 2), the 7-bit INPUT is set as the input number to be switched. If switching is
done using the machine’s front panel, these bits are set with the INPUT NUMBER switched. For other operations, these
bits are defined according to the table.
3rd Byte: Bit 7 – Defined as 1
O6…O0 – OUTPUT
When switching (i.e. instruction codes 1 and 2), the 7-bit OUTPUT is set as the output number to be switched. If
switching is done using the machine’s front panel, these bits are set with the OUTPUT NUMBER 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
This byte is used to address machines in a system by their machine numbers. When several machines are controlled
from a single serial port, they are usually configured together and each machine has an individual machine number. If
the OVR bit is set, then all machine numbers accept (implement) the command and the addressed machine replies.
When a single machine is controlled over the serial port, always set M4…M0 to 1, and make sure that the machine itself
is configured as MACHINE NUMBER = 1.
D – DESTINATION:
N5…N0 – INSTRUCTION
0 – Sends information to the switchers (from the PC)
1 – Sends information to the PC (from the switcher)

8.2 Instruction Codes
All the values in the table are decimal, unless otherwise stated
NOTES on the above table:
NOTE 1 – When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is
sent to a switcher, it resets according to the present power-down settings.
NOTE 2 – These are bi-directional definitions. If the switcher receives the code, it performs the instruction. If the
instruction is performed (due to a keystroke operation on the front panel), then these codes are sent.
For example, if the PC sends HEX code:
01 85 88 83
then the switcher (machine 3) switches input 5 to output 8.
If the user switches input 1 to output 7 using the front panel buttons, the switcher sends HEX code:
41 81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, if the instruction is valid, the switcher replies by
sending the same four bytes to the PC that it received (except for the first byte, where the DESTINATION bit is set high).
NOTE 3 – SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory,
(i.e. those used for Store and Recall).
NOTE 4 – The reply to a REQUEST instruction is as follows: the same instruction and INPUT codes that were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are
according to the definitions in instructions 7 and 8 respectively.
For example, if the present status of machine number 5 is breakaway setting, then the reply to HEX code:
0B 80 80 85
is HEX code:
4B 80 81 85

VS-81HDxl - Protocol 2000
NOTE 13 – This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as
1, 2, 5 or 7, the machine sends its name. The reply is the decimal value of the INPUT and OUTPUT.
For example, for a 2216, the reply to the request to send the audio machine name is HEX code:
7D 96 90 81 (i.e. 128
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine sends its software version
number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number
in front of the decimal point, and the OUTPUT representing the number after it.
For example, for version 3.5, the reply to the request to send the version number would be HEX code:
7D 83 85 81 (i.e. 128
If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent.
For example, for the VS-7588YC, the reply to the request to send the first suffix would be HEX code:
7D D9 C3 81 (i.e. 128
NOTE 14 – The number of inputs and outputs refers to the specific machine being addressed, not to the system.
For example, if six 16x16 matrices are configured to make a 48x32 system (48 inputs, 32 outputs), the reply to the HEX
code:
3E 82 81 82 (i.e. request the number of outputs)
would be HEX code:
7E 82 90 82 (i.e. 16 outputs).
NOTE 15 – When the OVR bit (4th byte) is set, then the video commands have universal meaning.
For example, instruction 1 (SWITCH VIDEO) causes all units (including audio, data, etc.) to switch. Similarly, if a
machine is in FOLLOW mode, it performs any video instruction.
NOTE 25 – For units that detect the validity of the video inputs, instruction 16 is sent whenever the unit detects a change
in the state of an input (in real-time).
For example, if input 3 is detected as invalid, the unit sends HEX code:
10 83 84 81
If input 7 is detected as valid, then the unit sends HEX code:
10 87 85 81.
