Banner ABR 7000 Series - User Interface-Serial Host

RS232 Interface
The RS232 interface is generally used for Point-to-Point connections. When it is connected to the host computer it allows
transmission of code data.
The following pins are used for RS232 interface connection:
TCNM-ACBB1 Function
TX
RX
SGND
Transmit Data
Receive Data
Signal Ground
Shielded cables are recommended. The overall maximum cable length must be less than 15 m (49.2 ft).
RS422 Full-Duplex Interface
The RS422 full-duplex (5 wires + shield) interface is used for non-polled communication protocols in point-to-point
connections over longer distances (maximum 1200 m / 3940 ft) than those acceptable for RS232 communications or in
electrically noisy environments.
The TCNM-ACBB1 pinout follows:
TCNM-ACBB1 Function
TX+

SGND
RS422 Transmit Data +
RS422 Receive Data +
RS422 Transmit Data -

Note: For applications that do not use RS422 transmission to the reader (terminal block RX+ and RX-
signals), do not leave these lines floating but connect them to SGND.
