ASCII Protocol: General
45
12 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:
1. Press the MENU button until you get to “set communication protocol”.
2. Choose the ASCII protocol.
This is saved in the non-volatile memory, so the machine remains in ASCII
even after turning OFF and ON.
3. To check that the protocol has been selected, and to confirm that the
communication is OK, send the string **!! to the VS-1616SDI.
It should reply by sending the string OK!!
13 ASCII Protocol: Description
The three basic commands are Y, T, and P.
“Y” command: MAKE A CROSSPOINT CONNECTION.
Format:
** 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).
Example:
**Y3,4!! connects input 4 to output 3.
**Y9,6!! connects input 6 to output 9.
**Y2,17,Y43,12,Y7,6!! connects input 17 to output 2, input 12 to output 43,
and input 6 to output 7.
The buffer allows up to 63 characters. Thus, a single string can include
about 10 cross-point connections.
Also:
**Y0,5!! connects input 5 to all outputs.
**Y3,0!! disconnects output 3.
