4.0 OPERATION
During normal operation the CAN-2 receiver will receive commands from the transmitter
and convert them to output or CAN signals. During these operations, the operator can
verify that the receiver is online and functioning by interpreting the status LED lights on
the front of the CAN-2 receiver. If there are errors during operation, the LED lights can
help troubleshoot the problem.
4.1 INITIALIZATION
During startup of the CAN-2 module, the signal strength/error code LED will illuminate to
provide initialization status.
Slow Blink Green = Initialization ok, no errors present
Blinking Red = Start up initialization error
After initialization is complete, the LED will then illuminate the signal strength and error
code status as part of the normal operation.
4.2 NORMAL OPERATION
During normal operation of the receiver, the receiver will receive commands from the
transmitter and convert them into outputs or CAN messages. During operation, the
receiver will communicate its status via LEDs.
4.3 LED STATUS INDICATION
The CAN-2 has three LEDs for indicating the CAN-2 status at a glance during normal
operation:
 The center LED labeled STATUS indicates the CAN-2’s signal strength/error
codes.
 The top LED (RF) indicates receiving of RF messages.
 The bottom LED (COM) indicates received CAN data.
4.3.1 RF Messages LED (Labeled RF on CAN-2 Faceplate)
 Green Slow Blinks = Transmitter is offline (watchdog indicator)
 Green Fast Blinks = Each blink is a valid RF message
 Red Solid = Error occurred; refer to Error Code LED's blink code
WARNING
DO NOT ASSUME THE POWER IS OFF IN THE RECEIVER BECAUSE THE TRANSMITTER IS
TURNED OFF. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS INJURY
OR DEATH AND DAMAGE TO EQUIPMENT.
