SERIAL PORT WIRING
Each EAS device is equipped with one RS232 serial port on the back panel. The serial
ports connect to and drive a variety of external video character generators and
BetaBrite LED signs. The software supports a wide variety of serial protocols, including
the most commonly used protocols in legacy EAS equipment, such as TFT Standard and
Sage Generic.
An optional USB/serial port expander can provide up to four additional RS232 serial
ports. This option is useful when additional character generators and LED signs are
needed.
Each serial port has the same pin-out, as shown below.
