Network Connection to E2
Connecting an XJ Scroll Condenser to an E2
unit requires the E2 to be version 2.84 or
above. Contact Retail Solutions for upgrade
information if the controller is a version before
2.84.
An E2 has up to three COM ports that can be
assigned for XJ Scroll board communication
(COM2, an RS485 port on the E2 power inter-
face board, and COM4 and COM6, which are
external RS485 cards). COM ports can only be
used for one function; in other words, if COM2
is set up as the I/O network, you cannot con-
nect XJ Scroll boards to COM2. If COM2 is
not used for XJ Scroll boards, ensure your E2
is equipped with an RS485 COM Card (P/N
637-4890) and configured in E2 General Ser-
I
vices (
tab) to enable COM4.
Connect the network cable to the three-termi-
nal connector on the COM port that has been configured as XJ Scroll.
When the E2 is at one end of the daisy chain, terminate the E2 with all three jumpers in the termi-
nated (UP) position.
