RS-232 Command Protocol
Host controller commands supported by the unit are defined below.
RS-232 Command Protocol Quick Reference
Legend: (All numbers must be two digits)
SW :
Switch (01-15) MM : Save Into Memory Bank (00-09)
BR : Baud Rate Code (12,24,48,96) LL : Load From Memory Bank (00-09)
OP : Output/User Port (01-MAXOUTPUTS) <CR>: Carriage Return (Hex 0xD)
IP : Input Port/CPU (01-MAXINPUTS)
Command String Good Response Description
CS SW,IP,OP *<CR> Connect one User port To CPU port
CA SW,IP *<CR> Connect all User ports To CPU port
RO SW,OP *<CR>IP<CR> Read Connection For User Port
CC SW,MM *<CR>MM<CR> Save Matrix Connections Into Memory Bank
RC SW,LL *<CR>LL<CR> Restore Matrix Connections From Memory Bank
CB 00,BR None Change Baud Rate For All Switches
RV SW,00 *<CR>string\0<CR> Read NTI Version String
RU SW *<CR>IP,OP<CR> Read Unit Size
SS SW,00 *<CR> Disable Autostatus feature (see below)
SS SW,01 *<CR> Enable Autostatus feature (see below)
GO SW OP *<CR>go SW OP IP<CR> Report the User port that is connected to the CPU port
GM SW,00 *<CR>go SW OP IP<CR>
(all connections) List all switch User port connections; all User ports to all CPU ports
If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch
memory, the command will be ignored. If the SW field corresponds to the serial address, but the syntax is wrong after this field,
the switch will answer with ?<CR>.
Syntax example:
CS 01,05,02<CR> (insert the space and commas as shown)
which means “At the switch with unit address 01, connect CPU port 05 to user port 02”
The switch will answer with:
∗<CR>
