These connectors provide eight serial outputs for IR or serial interface. Each output
is labeled S (signal) and G (ground). Infrared output is rated up to 1.2 MHz, at data
rates up to 115K. Serial protocols include one-way RS-232.
NOTE: Transmission levels on the infrared – serial output connectors are in the 0 to
+5VDC range, which may not be compatible with all RS-232 devices.

I/O
This connector provides eight software programmable analog and digital inputs as
well as digital outputs. Digital outputs offer 250mA sync from maximum 24 VDC;
catch diodes for use with "real world" loads. Digital inputs are rated 0 – 24 VDC,
20K ohms input impedance, logic threshold 1.25 VDC. Analog inputs are rated 0 –
10 VDC, protected to 24 VDC maximum, 20K ohms input impedance; pin-
programmable 2K ohms pullup resistor to +5V.
NOTE: Digital outputs are TTL values and may not work with devices requiring a
“dry” contact closure (e.g., low voltage motor controllers).

These connectors provide eight normally open, isolated relay contact groups. Each
relay contact closure is rated 1A, 30 VAC/DC; MOV arc suppression is provided
across contacts for use with "real world" loads.
