would be HEX codes:

NOTE 4 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the
instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than
the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via
the front panel. Reception of this code by the switcher is not valid.

NOTE 5 - 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 the machine
will send 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 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):

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 6 - 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 7 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 3 above, except that here the OUTPUT is
assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 8 - The reply to the request is as follows: the same INSTRUCTION and INPUT codes as were sent are returned and the OUTPUT
is assigned with the value 0 if no valid input is detected; or 1 if valid input is detected.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the
instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than
the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via
the front panel. Reception of this code by the switcher is not valid.

NOTE 25 - For units which detect the validity of the video inputs, Instruction 16 will be 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 will send the HEX codes:

If input 7 is detected as valid, then the unit will send HEX codes:

81.

NOTE 28 – In the automatic priority switch mode, in the case where the user tries to switch manually, and there is no valid input the unit
will wait the number of seconds configured by this command until the input becomes valid and then execute the switching. If during this
delay the input remains invalid the switching will not execute.
