INPUT
This 5-pin connector provides four software programmable digital inputs plus
ground. The inputs are Schmidt trigger type (nominal 2.5 V threshold) with
24 V input tolerance.
Digital inputs are rated 0 – 24 VDC, 20K ohms input impedance.
IR

IR
The 2-position mini-connector is a mini-implementation of a single PRO2 IR
port. The output is labeled S (signal) and G (ground), for controlling devices
via IR or one-way RS-232. (Depending on the control format, additional
equipment such as IR emitters, splitters, receivers, and remote control
transmitters may be required).
Infrared output is rated up to 1.2 MHz. Serial protocol is one-way RS-232.
COM B
COM A
COM (A & B)
These two DB9 (male) software programmable, bi-directional serial ports are
available for RS-232 communication, with hardware and software handshaking
and modem control. Speeds are rated up to 115,200 bps. COM B can also be
used as the console port.
A null modem cable is required to connect to a computer.
NOTE:
RS-422 and RS-485 are not supported.
