NTI UNIMUX SINGLE-USER HIGH DENSITY VGA USB KVM SWITCH

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 33)

•use the NTI Switch Control Program (page 34) provided on the CD

•use the SerTest or RMTEST programs (pages 34 and 36) provided on the CD

Remote Connection

The RS232 Interface 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 9). To daisy chain multiple units, connect a Matrix-Y-1 cable (sold separately) between the CPU and the first switch, and between each switch (as shown in Figure 39).

Baud Rate

The baud rate can be changed using the OSD menu (page 31) or from the RS232 commands (page 33) . The baud rate can be set to 115000, 57600, 38400, 19200, 9600, 4800, 2400, or 1200. A data protocol of 8 data bits, no parity, and 1 stop bit is used for communications.

Unit Address and Loop Back

To allow multiple units to be controlled from a single host port, the RS232 control interface is designed to allow "daisy chaining" up to 15 units using an NTI Matrix-Y-1 cable. Connect the Matrix-Y-1 cable between the RJ45-to-DB9 serial adapter and the CPU as shown in Figure 39. By setting the appropriate unit address (page 31), 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.
