Encore — Installation and Service Manual 61
Serial Cabling RS-422/485
The customer supplied cabling from the ivory RJ-45 connector to the device
is not specified but here are a few guidelines:
• Use the shortest cabling practical for the installation,
• When using RJ-45 to D type serial adaptors, put the adaptor as close to
the device as possible, ideally connect the adaptor to the device, and
• Use Cat 5e Ethernet patch (pin-to-pin) type cabling with RJ-45 connec-
tors to either the device or the adaptor on the device.

Redundant Cabling for Device Control of Encore
Redundant serial port cabling where a device controls Encore requires the
Serial Interface Y Cable Option (Y cable). The Y cable is needed when a
device such as an automation system on a PC-compatible, or a router is
using a single serial port to control Encore. The Y cable option contains
enough cables and connectors to create four Y cables.
The crossover cables (174821600) in the Serial Interface Y Cable Option can
also be used for non-redundant cabling to the original Encore Control
frame (6100884xx).
