RS232 CONTROL

RS232 enables the UNIMUX to be remotely controlled via RS232. To control the UNIMUX via RS232 the user has three options:

•write a program that runs on a PC using the Command Protocol (page 15)

•use the NTI Switch Control Program (page 16) provided on the CD

•use the SerTest program (page 16) provided on the CD

RS232 Connections and Configuration

Remote Connection

The RS232 Interface (optional) is designed to meet the RS232C standard and can be controlled from any CPU or other controller with an RS232 communications port. The pin-out for the RJ45 connector on the unit is as follows:

A 5 foot patch cable and two adapters, RJ45-to-DB9 and RJ45-to-DB25, have been provided for connection to most CPUs (see page 8).

Baud Rate

The baud rate can be changed by powering down the unit, changing the 8 position RS232 DIP switch on the front of the UNIMUX, and then powering back up. This table shows how to set the baud rate. (Fig. 10 shows switches in their factory default position.)

Unit Address and Loop Back

To allow multiple units to be controlled from a single CPU serial port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units. By setting the appropriate RS232 DIP switches, each unit can be given a unique address (1-15). Then the unit will only respond to commands on the bus if its address is embedded in the command. Use the following table to set the unit address.
