NTI KEEMUX Series PS/2 KVM Switch
Command Protocol
Host controller commands supported by the unit are defined below.
Notes:
•All commands should be terminated with an <Enter> (ASCII 13) denoted by <CR>. When a command is sent, the entire string is echoed back to the CPU along with a response from the addressed unit as shown in the command definitions. Unit response will be sent within 500 msec after <CR>.
•Use a program that will send an entire command line all at once, not character by character. Do not use the program HyperTerminal in WINDOWS, as it sends each character one at a time.
• All characters should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01).
•For units with one USER port, use 01 for the USER select.
RS - reset unit(s) to default
FORMAT: RS AA<CR>
RS = "reset unit" command followed by at least one space
| AA = unit address; if 00, all units on the bus will be reset and no response will be |
| returned |
RESPONSE: | *<CR> if command received and executed OK |
|
?<CR> if syntax or transmission error occurred
Note: The RS command does not change the actual configuration.
CS - change single USER channel
FORMAT: CS AA,XX,YY<CR>
CS = "change single output" command followed by at least one space
AA = unit address
XX= input/CPU to connect
YY= output/USER to change
RESPONSE: | *<CR> (command received and executed OK) |
?<CR> (syntax or transmission error occurred)
CA - change all output channels
FORMAT: | CA AA,XX<CR> |
| CA = "change all outputs" command followed by at least one space |
| AA = unit address |
| XX = input /CPU to connect to all outputs/USERS |
RESPONSE: | *<CR> (command received and executed OK) |
| ?<CR> (syntax or transmission error occurred) |
