NOTES on the above table:

NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it performs 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

was sent from the PC, then the switcher (machine 3) switches input 5 to output 8. If the user switched input 1 to output 7

via the front panel keypad, then the switcher sends HEX codes:

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

would be HEX codes

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 would be (HEX codes):

81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).

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 codes):

81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 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):

81 (i.e. 128dec+ ASCII for “Y”; 128dec+ ASCII for “C”).

NOTE 14 - The number of inputs and outputs refers to the specific machine which is 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

82 (ie. request the number of outputs)

would be HEX codes

ie. 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 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte.

The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.
