Unit Address
In order for a terminal to communicate with one or more NODEMUX switches, each switch must have a unique address. The
NODEMUX will only respond to commands from a terminal if its address is embedded in the command. Up to 15 NODEMUX
switches can be connected in a "daisy chain" to a terminal, each with its own unique address.
To set the address of the NODEMUX, from the Switch Configuration mode menu (Fig. 15 on page 17),
press until the cursor bar moves to highlight "RS232 UNIT ADDRESS".
press or until the desired address (1-15) is selected.
Exit Switch Configuration Mode
Once changes are made to the Switch Configuration menu, press and to save them.
To exit without saving, press , then , then again. The menu will return to the Administration Mode without
saving the changes made. .
Changes made will take effect the next time the NODEMUX is power cycled.
Command Protocol
Terminal control commands supported by the NODEMUX are defined below.
Notes:
• All commands should be terminated with an (ASCII 13) denoted by . When a
command is sent, the entire string is echoed back to the terminal along with a response from the
addressed unit as shown in the command definitions. Unit response will be sent within 500 msec
after .
• 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 (i.e. this NODEMUX switch), use 01 for the USER select.
