Sensor Power
The module shall monitor Port Sensor Power current and shut off the sensor power in a port if the maximum current exceeds 3 amps
per port. Both short circuit and overcurrent protection is provided.
Module Power
The module power delivered by the CAN ports has short circuit protection. This circuit has a separate ground that is supplied by the
CAN port as well, Ground (A)
S1 = Port 1 power, 3 amps.
S2 = Port 2 power, 3 amps.
S3 = Port 3 power, 3 amps.
S4 = Port 4 power, 3 amps.
S5 = Port 5 power, 3 amps.
S6 = Port 6 power, 3 amps.
S7 = Port 7 power, 3 amps.
S8 = Port 8 power, 3 amps.
Module default configuration:
• Factory Default Config returns 1 in Status message 1-Status 1, this should not be on if the module has been configured.
• Default operation of the module is on/off digital control. PWM control messages are not needed.
• Default configuration does not require a Command 0x52 message to enable operation.
