Communications ports
Separate CAN and serial ports provide complete communications and program-
ming capability for all user available controller information.
The Curtis 1311 handheld programmer plugs into a connector wired to
pins 28 and 29, along with ground (pin 7) and the +12V power supply (pin
25); see wiring diagram, Figure 3. The Curtis Model 840 display can plug into
the same 4-pin connector.
Wiring the CAN Term H and CAN Term L pins together provides a local
CAN termination of 120 Ω, 0.5 W; keep the length of these wires short. CAN
Term H and CAN Term L should never be connected to any external wiring.

Encoder inputs
Two control lines are internally configured to read a quadrature type position
encoder. The encoder is typically powered from the 5V supply (pin 26) or 12V
supply (pin 25), but can be powered from any external supply (from 5 V up
to B+) as long as the logic threshold requirements are met.
