RS-232 / RS-485 Communication Protocol
27
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send 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 codes):
7D 83 85 81 (i.e. 3dec for 2nd byte, 5dec for 3rd byte).
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 codes):
7D D9 C3 81 (i.e. ASCII for “ Y” ; ASCII for “ C” ).
NOTE 14 - The number of inputs and outputs refers to the specific machine, which is being addressed, not to the system.
NOTE 15 – When the OVR bit (4th byte) is set, then the “ video” commands have universal meaning. For example,
instruction 1 (SWITCH VIDEO) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in
“ FOLLOW” mode, it will perform any “ video” instruction.
NOTE 16 - The reply to the “ REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the
OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
NOTE 17
– Delayed execution allows switching after a delay dictated by RS-232. To do this, the user sends instruction 7
with the “ Set for delayed switch” option (64dec) before sending the switch command (instruction 1) or pressing via front
panel. The switch is not executed (unless timed-out) until the “ Execute delayed switch” code is sent, or the “ “ Set for delayed
switch” code is sent again. (The mode is automatically cancelled after implementation of the switch if the “ execute”
command is used).
For example, to connect input 4 to output 3 after a delay, send HEX codes
07 80 C0 81 (set for delayed switch)
01 84 83 81 (switch code)
then, after the required delay, send HEX codes
07 80 C1 81 (execute delayed switch)
to implement the switch.
NOTE 17A – For clean switching of RGBHV video, the “ seamless switching” option may be used. The blanking period for
the transition of the RGB sources may be set in this case, in steps of 25 milliseconds.
For example, to set for 350ms blanking time (14 steps), send HEX codes:
07 8E A0 81
NOTE 18 – After this instruction is sent, the unit will respond to the ASCII command set. The ASCII command to operate
with the HEX command set must be sent in order to return to working with HEX codes.
NOTE 19 – When data (ie. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, this instruction is sent before
sending the instruction needing the additional bits. The data in this instruction then becomes the Most Significant Bits of that
next instruction. For example, to set the audio gain (instruction 22) of output 3 to 681dec (2A9hex), you would first send
HEX codes
3F 80 85 81
and then send HEX codes
16 83 A9 81
To set the audio gain of output 4 to 10013dec (271Dhex), first send HEX codes
3F 80 CE 81
followed by HEX codes
16 84 9D 81
NOTE 20
– To store data in the non-volatile memory of the unit, e.g. the EEPROM for saving SETUPS. The EEPROM
address is sent using the INPUT byte, and the data to be stored is sent using the OUTPUT byte. To use this instruction, it is
necessary to understand the memory map, and memory structure of the particular machine.
NOTE 21
– Instruction 59 and instruction 60 load data for sending to the crosspoint switcher (or for storing in a SETUP), i.e.
the data is “ lined-up” to be executed later. Instruction 58 executes the loaded data.
NOTE 22 – If the INPUT byte is set as 127dec, then the data stored in a SETUP is loaded. The SETUP # is in the OUTPUT
byte.
NOTE 23
– Further information needed in instructions 21, 22, 25 and 26, is sent using instruction 42 – which is sent prior to
the instruction. For example, to request the audio gain value of right input # 5, send hex codes
2A 84 80 81
and then send HEX codes
19 85 81 81
