NOTES:

A. I/O common pins, C, are internally connected to the power supply negative.
B. Digital inputs are configurable for positive or negative logic using Cscape.
C. When configured for positive logic, the inputs are pulled down to common by a 10K resistor. When an input is open or low, the

associated LED is OFF and the associated OCS register bit is 0. When an input is driven high above the threshold level, the
associated LED turns ON, and the associated OCS register bit is 1.

D. When configured for negative logic, the inputs are pulled up to the positive supply voltage, V+, by a 10K resistor. When an

input is open or high, the associated LED is OFF and the associated OCS register bit is 0. When an input is driven low, below
the threshold, the associated LED turns ON, and the associated OCS register bit is 1.

2. CAN Wiring

CAN Network & Power Connector
Torque rating 4.5 – 7 Lb.-In. (0.50 – 0.78 N-m)

Network, Power, and Grounding:

A single 5 pin connector is used to make both a network connection and power input. A quality class 2 power supply should be used for
this product. If the power is run with the network cable, care must be taken such that the voltage does not drop below the lower supply
limit on longer runs.

A quality earth ground is required for safe and proper operation. The best ground is achieved by screwing the lower left grounding
location into a grounded back plate. Alternately, a ground can be connected to the spade lug.
Please see Horner manual MAN0799 for details on CAN wiring.
