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.

RS-232 Serial Interface Signal Voltage and Current levels
Voltage Levels Max +-15 Volts
Min +- 3 Volts
Mark = Off = -3 to –15 Volts
Space = On = +3 to +15 Volts
Because both the host and printer are DTE's (Data Terminal Equipment), they use the same serial port pin-outs. If the cable that is used to connect the host to the printer is a pin-to-pin inter-connect, it will not work. Therefore, a null modem or turn-around cable must be used to interconnect the host and the printer.
USB Interface
The USB interface is a Version 1.1 interface that is Version 2.0 compliant. The standard USB interface card is implemented through a Standard Series "B" Receptacle as defined in the USB Specification. The printer is self-powered and does not draw power from the standard type B USB interface cable.
The Standard USB Type B connector has the following pin functions:
Pin Signal
1 Vbus (+5 V dc) (Not used in the BANKjet® 2500)
2 Minus data
3 Plus data
4 Ground
Note: The standard USB interface does not have enough power to run the printer.
