2100DE’s Prompts and Responses
After the VFC-2100DE receives a command it will respond by transmitting one of the following messages:

‘#’: Command completed, ready for next command.

‘?’ followed by a LF/CR and a ‘#’: Did not understand last command or could not complete
command.

‘=’: Inquiry processed, data to follow this ‘=’. The length of the data stream depends upon the
command sent. The data stream is followed by a LF/CR and a ‘#’.

When the VFC-2100DE is powered-
up, it will transmit a banner followed by ‘#’. This signifies that the VFC-2100DE is
ready for commands. The banner is:

The command syntax for a single command is shown below:
cds id cmd arg1 arg2 arg3..argn cde
Cds Cds is the command delimiter start character '*' (ASCII 42).
Id
Id
is the device number in the range of 1 to 32. This can be a single character for values less than
10; no preceding zero is required.

Cmd is any valid VFC command, typically 2 to 6 characters in length
Arg
Arg1, 2, n is any required or optional parameters need for the command
Cde Cde is the command delimiter end character '!' (ASCII 33).
Example: To adjust the horizontal center 10% to the right relative to its current position on Scaler B, the command
format would be:
*2AOIHC R 10 B! Assuming the device id is set to 2.
To minimize bus traffic the command words will be kept as short as possible. The units will not respond with prompts
or any command error conditions. Echo will be disabled when the RS422 or 485 modes are selected.
