LOCAL, HOST, and USER I/O. The LOCAL Connector contains the RS-
232C signals for a serial terminal that can be used to program the
system parameters and monitor activity. The HOST Connector contains
the RS-232C, RS-422, or optional RS-485 signals that will be sent to the
host computer or other control device.
provides logic level status pulse outputs, gating and push-button

system operating parameters and monitor scanner operation if desired.
It is set to 9600 baud, 1 start bit, 8 data bits, no parity bit, 1 stop bit
