Publication 1747-UM011, SLC 500 Modular Hardware Style User
Manual, contains complete instructions and guidelines for DH-485
link planning.
In normal operation with the programmable controller connected to
the link coupler, the processor powers both the link coupler and the
peripheral device (DTAM, PIC, HHT) — if connected — through the
1747-C11 cable. No external power supply is required.
If you do not connect the processor to the link coupler, use a Class 2
24V dc power supply to power the link coupler and peripheral
device.
