Allen-Bradley SLC 500

C–3Setting Up the DH+ Network
Publication 1747-6.2
To connect Allen-Bradley devices with other devices over DH+, you
must wire the 3-pin cable connectors so that communication can
occur through the cabling. Each device requires its own node
address.

Terminate the DH+ link on both ends by connecting a 150Ω, 1/2W
resistor between terminals 1 and 2 of the 3-pin connector when you
are communicating at 57.6K baud with a PLC-5 processor or
115.2K baud with other SLC 5/04 processors. Use an 82Ω, 1/2W
resistor if you are communicating at 230.4K baud with other
SLC 5/04 processors or Series E enhanced PLC-5 processor.
