Communication Protocols
53
11.2
ASCII Protocol: General
The ASCII protocol has three basic commands:
Y
for connect
,
T
for recall
,
P
for store
. Before using the ASCII protocol, you need to select it from the
machine’ s front panel. Press the MENU button until you get to “ set
communication protocol” and then choose the ASCII protocol. This is saved
in the non-volatile memory, so the machine will remain as ASCII even after
cycling power. To check that the protocol has been selected, and to confirm
that the communication is OK, send the string **!! to the VS-3232V. It should
reply by sending the string OK!!
11.2.1 ASCII Protocol: Description
The three basic commands are
Y
,
T
, and
P
.
“Y” command: MAKE A CROSSPOINT CONNECTION
. The format is:
** Y o#, i# !!
where i# is the input number, and o# is the output number.
Note: The string does not need a space (spaces are used here just to add clarity
to the explanation).
For example:
**Y3,4!! would connect input 4 to output 3
**Y9,6!! would connect input 6 to output 9
**Y2,17,Y25,12,Y7,6!! would connect input 17 to output 2, input 12 to output
25, and input 6 to output 7.
The buffer allows up to 63 characters. Thus you could place up to about 10
crosspoint connections in a single string.
Also:
**Y0,5!! would connect input 5 to all outputs
**Y3,0!! would disconnect output 3
“T” command: RECALL A SETUP
. The format is:
** T s# !!
where s# is the setup number (1 to 59) which is to be recalled.
For example:
**T13!! would recall setup number 13
“P” command: STORE A SETUP
. The format is:
** P s# !!
where s# is the setup number (up to 59) where the machine’ s
present status is to be stored.
For example:
**P13!! would store in setup number 13
The reply for all commands could be:
OK!! or ERROR!!
