Way Communications is an important topic with regard to
ZigBee Mirror Modules. This topic will be discussed at length
on this page. It is a vital part of understanding how the con
‐
troller functions.
Step 10: Understanding 2
‐
Way Communications
ZigBee Mirror Modules work by sending a relay control com
‐
mand to a remote relay controller. In this mode, the ZigBee
Mirror Module then waits for a confirmation byte from the
relay controller. If a confirmation byte is not received, the Zig
‐
Bee Mirror Module will change the READY LED to BUSY. Every
time an error in communication occurs, the READY/BUSY LED
will flash.
THIS DOES NOT MEAN THE RELAY DID NOT ACTI
‐
VATE. THIS SIMPLY MEANS DATA DID NOT PROPERLY COM
‐
MUICATE BOTH DIRECTIONS. IT IS NORMAL FOR THIS LED TO
FLASH OCCAISIONALLY UNDER NORMAL OPERATION. IN SOME
CASES, IT MAY FLASH COSTANTLY AND STILL BE FUNCTIONING
PROPERLY.

Way XR Port Confirmation
When the 2
‐
Way XR Port Confirmation mode is selected, the
ZigBee Mirror module sends a command to activate a remote
relay, and then waits for a confirmation byte from the remote
relay controller. Next, the ZigBee Mirror Module will ask the
remote relay controller the status of the remote relay. Status
data is then sent directly to the XR Relay Expansion port. By
connecting the
XR16OCLP
controller (shown at right) to the XR
Expansion Port of the ZigBee Mirror Module, the LEDs will indi
‐
cate the status of the remote relay.
In the event power is lost at a remote relay controller, the
XR16OCLP may still indicate the relay is On. Triggering any
Contact Closure input will Refresh the display to the current
status of the remote device. Some users may want to connect
a push button to any available input to manually trigger a
“Refresh” condition.
When power returns to the remote relay controller, the relay
will automatically update to the current state of the corre
‐
sponding ZigBee Mirror Module inputs. Some user settings
may prevent automatic relay refresh from occurring.

Helpful Hint:
The XR Expansion Port is compatible with ANY

Understanding LED Status Lights
A ZigBee Mirror Module is equipped with 2 LEDs that help you identify communication errors. Under the best of conditions, the READY
LED will always be ON and you will never see the BUSY LED flash. This indicates perfect communications. In reality, this is rarely the
case. ZigBee Mirror Modules expect to hear back from remote devices within a very short time frame. If they do not respond quick
enough, the ZigBee Mirror Module will flash the BUSY LED. THIS DOES NOT MEAN MIRRORING WAS NOT SUCCESSFUL. It simply
means the remote relay controller did not respond within the allotted time frame. The controller will constantly try to Mirror data
from the Inputs of ZigBee Mirror Module to the Remote Relay. The Busy LED may flash for long periods of time and still work properly.
