Getting Into The Communications Setup Mode
From the MAIN menu, the Executive Menu can be selected. This is done by pressing the

Communications Setup Parameters
There are 4 parameters that can be programmed from this screen.
Comm./IO Lock Code
The Comm. / IO Lock Code parameter provides safeguarding against tampering with either the
I/O program or the communications parameters. You can enter any 4 digit number for a lock code. A code
of 0 disables this feature. If you use it, whenever you enter into this menu or try to change the I/O program,
you will be prompted for the lock code. Make sure that you don't forget what you set it to, as there is no
way to disable this feature unless you know the code.
Keyboard Beep
The Keyboard Beep parameter, which controls the audible feedback when pressing keys, can be
disabled if desired. A value of 1 will turn the beeper Off and a value of 2 will turn it on.
RS-232 Baud Rate
The RS-232 Baud Rate parameter sets the baud rate for the RS-232 interface. It can be
programmed to one of 4 values. A value of 1 is 300 baud, 2 is 1200 baud, 3 is 2400 baud, and 4 is 9600
baud.
