Communications
Separate CAN and serial ports provide complete communications and pro-
gramming capability.
The Curtis 1311 handheld programmer plugs into a 4-pin connector
wired to pins J3-1 and J3-3, along with ground (pin J3-2) and the +12V power
supply (pin J3-4); see wiring diagram, Figure 3. The Curtis Model 840 Spyglass
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.
