link is hooked up correctly (blinking green with no messages, solid green with messages) or
incorrectly (red). The MS LED gives the status of the unit. If it is green the unit is operating normally.
If it is blinking red the unit is out of memory, while solid red means the device has failed and may be
need to be power cycled or be repaired. Please refer the WRC CANX or CANR User’s Manual and
see the section on “LED Operation.”
14. Do WRC CANX and CANR extenders cause signal delays, and what speed of messages can

message forwarding as well.
15. What testing has WRC completed to guarantee the reliable operation of CANX and CANR
extenders?
The WRC production and engineering teams have rigorously tested the CANX and CANR
extenders at a variety of strenuous network speeds and environmental conditions with many
different network configurations. Although there is no official ODVA test for this type of device, the
CANX and CANR have been included in the circuit while running the ODVA conformance testing for
a slave device. The slave device passed WRC’s in-house protocol conformance test with the CANX
or CANR in the circuit, between the master and slave. The CANX and CANR also passed the in-
house execution of the OVDA physical layer test. Each CANX or CANR pair is tested for
functionality individually before leaving our facility.
16. How does the Series 4 WRC CANX or CANR differ from the Series 3 model?
Single Mode fiber cable is now an option, available with the Series 4 CANR. New switch settings
allow selection for CANopen speeds up to 1M baud in addition to the standard DeviceNet baud
rates. There are larger internal buffers, which allow the WRC CANX and CANR to store more
messages while forwarding them in a first-in-first-out manner, making it even less likely that a
message will ever be lost in transmission. There is shorter latency time compared to CANX and
CANR series 3. The CANX and CANR also feature improved reverse voltage protection and CAN
data lines noise immunity.
17. Does the WRC CANX or CANR come with a warranty?
Yes, the WRC CANX and CANR, like all WRC products, are covered under a two year factory
warranty from the date of invoice that all hardware furnished under order will be free from defects in
material, workmanship and design.
18. How are field programming updates accomplished?
In the event that your WRC CANX or CANR is in need of an update, contact WRC. We will discuss
with you the options you have for your network.
