The Output Board accepts 12VDC with an operating range of 10 to 14VDC and
consumes 385mA of current. Locate the power source as close to this board as
possible. Connect power with minimum of 18AWG cables.
Note: POLARITY for 12VDC power is important. Make sure the +12 VDC is connected to
the terminal labeled +12V and the return is connected to the terminal labeled GND.

Communications

The Output Board communicates to the host controller through an RS-485
interface.The interface allows for multi-drop communication of up to 4,000 feet
(1,200 m) total per port. Use two twisted pair (minimum 24AWG) with shield (Belden
9842 or equiv.) for communication. The default speed of this port is 38.4Kbps but it
can be downgraded to 19.2Kbps or 9.6Kbps if the line conditions or receiving
equipment require it (see
page 11 for DIP switch settings).
For wiring to an RS-485 port:
1. TR+ is the plus side of the transmit and receive differential signal.
2. TR- is the negative side of the transmit and receive differential signal.
3. GND is the signal ground. The wiring for this signal is required and
4. Use 24 AWG low capacitance, two twisted-pair, shielded cable (Belden 9842
