Encore — Installation and Service Manual 59
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.
Figure 35. Non-Redundant Cabling for Encore Control Frame 6100884xx
Redundant Cabling for Encore Control of Device
Redundant Encore control of serial devices is similar to non-redundant
cabling.The redundant Encore controllers have to be the same type either
frame 6101000xx or frame 6100884xx. One serial connection from each of
the two Encore controllers needs to be connected to two separate serial
ports on the controlled device.
Figure 36 shows redundant cabling using an Encore frame 6101000xx.
There is a connection from SIO Port 5 on the Encore frame from the Con-
troller in Slot 1 to a serial port on the controlled device. There is another
connection from
SIO Port 5 on the Encore frame from the Controller in Slot 2
to a separate serial port on the controlled device. These connections can use
standard patch cables (pin-to-pin).
