Installing the DH-485
Communication Cable

Publication 1747-UM011, SLC 500 Modular Hardware Style User
Manual,
contains complete instructions and guidelines for DH-485
link planning.

Powering the Link Coupler

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.
