Command Protocol   

RS232 commands supported by the unit are defined below. All command strings should be terminated with a <CR> (carriage 
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the 
command definitions.  All characters in the command string should be upper case, and all numbers below 10 should have a 
leading 0 (ex: 1 = 01).   As command strings are sent, the inner character delay cannot exceed 500 milliseconds.    
 
 
 
 
 
 
 
 
 
 
 
 
 

                                                Figure 13- RS232 Communication Illustrated 

 
Note: To use this command protocol, the user is required to write a program that will send an entire command string all 
at once, not character by character.  Programs that send one character at a time (such as HyperTerminal) cannot be used 
to control the UNIMUX.   Alternatively, the user may use the NTI Switch Control Program or SerTest to control the 
UNIMUX via RS232 (see page 15).

*<CR> 

Connect Output (User) Port  To specific Input (CPU) Port 

RO SW,OP 

*<CR>IP<CR> 

Read Connection For Output  (User) Port to Input (CPU) Port 

RS SW 

*<CR> 

Internal Reset 

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> 

Read connection of a Output (User) Port  to Input (CPU) Port 
(different response format than RO command) 

GM SW,00 

*<CR>go OP,IP (all ports)<CR> 

Read connection matrix of all Output (User) ports 

 
If the first field is not a known command (as listed above) or SW field is different from the unit address programmed at the dip 
switch (page 12), the command will be ignored.  If the SW field corresponds to the unit address, but if the syntax is wrong after 
this field, the switch will answer with a bad response  ?<CR>. 
 

Autostatus 

When Autostatus is enabled, any output (user) -to-input (CPU) connection change in the UNIMUX will cause an Autostatus 
message to be sent via RS232 to the administrator.     The format of the message would be "pc SW,OP:IP<CR>" 
 
Example of an Autostatus message: 

 

  

pc 01,01:04<CR>           

 

which means  "At the switch with unit address 01,  the output (User) (01) has changed connection to input (CPU) port 04."   
 

Note:  An Autostatus message to the administrator will be delayed by any RS232 traffic being received by the switch 
from the administrator.       

 

By default,  Autostatus is disabled and must be manually enabled.
