ADDENDUM:
VS-1616A, VS-1616AD, VS-1616SDI, VS-1616V, and VS-162V
This addendum describes the ASCII protocol in the 1616 series. The ASCII protocol
applies to firmware version 3.3 or higher.
ASCII Protocol: General
The ASCII protocol has 3 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-1616A. It
should reply by sending the string OK!!
ASCII Protocol: Description
The 3 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,Y43,12,Y7,6!! would connect input 17 to output 2, input 12 to output 43, 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 99) 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 99) 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!!
