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
