RS-232 Serial Interface

There are two serial interface cards available. One is a 9-pin, D-shell connector. The pin-out is such that the printer
interfaces to a standard IBM PC Serial printer interface with a Serial Null Modem cable. The second interface card
provides the same interface with a standard 25-pin D-shell connector. Both interface cards provide a dual cash
drawer interface. The tables below lists interface signals and pin definitions for both types of serial interfaces.
