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.

Note: All values in the table are decimal, unless otherwise stated.
INSTRUCTION DEFINITION FOR SPECIFIC INSTRUCTION NOTE
# DESCRIPTION INPUT OUTPUT
0 RESET DEVICE 0 0 1

be switched
(0 = disconnect)
Set equal to video output which is
to be switched
(0 = to all the outputs)

4 RECALL VIDEO
STATUS
Set as SETUP # 0 2, 3, 15
5 REQUEST STATUS
OF A VIDEO OUTPUT
Set as SETUP # Equal to output number whose
status is required
4, 3
15 REQUEST WHETHER
SETUP IS DEFINED /
VALID INPUT IS
DETECTED
SETUP #
or
Input #
0 - for checking if setup is defined
1 - for checking if input is valid 8
16 ERROR / BUSY For invalid / valid input (i.e.
OUTPUT byte = 4 or OUTPUT byte
= 5),
this byte is set as the input #
0 - error
1 - invalid instruction
2 - out of range
3 - machine busy
4 - invalid input

56 CHANGE TO ASCII 0 3 – Protocol 3000l 19
61 IDENTIFY MACHINE 1 - video machine name
3 - video software version
0 - Request first 4 digits
1 - Request first suffix
13
62 DEFINE MACHINE 1 - number of inputs
2 - number of outputs
3 - number of setups 1 - for video
3 - for SDI
4 - for remote panel
5 - for RS-422 controller 14
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
the switchers, it will reset according to the present power-down settings.
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if
the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the
HEX code
01
85 88 83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7
via the front panel keypad, then the switcher will send HEX codes:
41
81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by
sending to the PC the same four bytes that it was sent (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 as were sent are
returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per
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 the HEX code
0B
80 80 85
would be HEX codes
4B
80 81 85
