RMTEST-RS232 Interface Test Program

NTI UNIMUX MULTI-USER KVM SWITCH

This software also allows a user to test the functions of an NTI server switch, matrix switch or Multi-user/Multi-platform switch RS232 interface. The RMTEST program is automatically loaded when installing the Matrix Switcher’s Control Program as described on page 32. The RMTEST program, located in the NTI program group, generates a main menu with the 3 selections described below:

MAIN OPTIONS

1.	Matrix Options	- send commands to the matrix unit.
2.	Setup Options	- set COM port, baud rate, and unit address
3.	Quit	- quit the program

If Matrix Options is selected, the following menu, which has 7 options, is displayed:

MATRIX OPTIONS

1.	Reset single unit	- reset single matrix to power-up defaults (matrix switch only)
2.	Reset all units	- reset all daisy chained matrix units (matrix switch only)
3.	Change single output	- connect an input to one output
4.	Change all outputs	- connect an input to all outputs
5.	Read single output	- read which input is connected to an output
6.	Read unit size	- read how many inputs and outputs the unit has
7.	Return to main menu	- go back to the MAIN OPTIONS menu

The Setup Options main menu selection only needs to be executed if the switches baud rate or unit address have been changed from the factory defaults ( 9600 baud, and unit address = 1). When this option is selected, the following menu, which has 4 options, is displayed:

SETUP OPTIONS

1.	Set COM port (default = COM1)	- set port to COM1-COM3
2.	Set baud rate (default = 9600)	- set baud rate (see interface manual for supported baud rates)
3.	Set unit address (default = 01)	- set the unit address (if multiple units are daisy-chained)
4.	Return to main menu	- Go back to the MAIN OPTIONS menu

For any selection that requires user input, the user is prompted. When commands are sent to the matrix unit, the command string and matrix unit responses are echoed to the screen. All commands generated by the program are formatted according to the information provided in the sections above. If any transmission problems are detected, an error message is displayed.
