4.3.2 Signal Strength/Error Code LED (Labeled STATUS on CAN-2 Faceplate)
 Solid Green = Good RF signal strength to transmitter
 Solid Yellow = Average RF signal strength to transmitter
 Solid Red = Low RF signal strength to transmitter
 Blinking Red = Error (code is picked up from number of blinks)
o Red 2 Blinks – Commanded Power Down
o Red 3 Blinks – RF Data Timeout
o Red 4 Blinks – CAN bus Timeout
o Red 5 Blinks – Initialization / Hardware Error
o Red 6 Blinks – Machine Stop Power Down
o Red 7 Blinks – Invalid RF Firmware
Refer to Section 7.0 for the troubleshooting table to interpret error codes.
NOTE: SIGNAL STRENGTH/ERROR CODE LED only illuminates green when the receiver is
online with the transmitter. The SIGNAL STRENGTH/ERROR CODE LED will not illuminate
green after the transmitter goes offline from the receiver. This can occur when the transmitter
powers down from inactivity or goes out of range. The START toggle on the transmitter must be
toggled to bring the transmitter back online with the receiver.
4.3.3 Communication LED (Labeled COM on CAN-2 Faceplate)
During normal operation, if there is CAN data currently being received on the bus this
LED will light solid blue as an indication that the CAN bus is connected properly.
4.4 INFRARED COMMUNICATION
The CAN-2 is equipped with an infrared (IR) port that is used when pairing a transmitter with the
CAN-2. Please refer to the appropriate transmitter manual for instructions on how to use this
feature (if supported by the transmitter).
The IR port is accessible when the board is within the housing. There is no need to remove the
board from the housing to utilize the IR pairing feature. See Figure 11 for the location of the IR
port on the CAN-2.
