SP7100 CAN Interface
3. Function specifications
Probe setting selector
(Setting applies to both
CH1 and CH2)
Serves as a switch for setting the Non-Contact CAN Sensor’s probe setting function
when used in combination with the Non-Contact CAN Sensor.
• FIXED
Outputs the detected signals without additional processing even if the Non-Contact
CAN Sensor detects that the Signal Probe connections to the CAN bus’s CAN_H and
CAN_L lines are reversed.
• AUTO
If the Non-Contact CAN Sensor detects that the Signal Probe connections to the CAN
bus’s CAN_H and CAN_L lines are reversed, switches the high and low connections
via its internal circuitry.
Output bus error
detection function
(Configured separately
for CH1 and CH2)
•This function determines that an output error has occurred when signals other
than output from the CAN Interface are present on the bus output from the device
connected to the CAN signal output connector.
•The output bus error detection function will not operate if the Non-Contact CAN
Sensor’s probe CAN_H/CAN_L reverse connection detection function determines that
the Signal Probes have been connected to the CAN bus’s CAN_H and CAN_L lines
in reverse.
•If an output bus error is detected, the LED is displayed according to LED lightning/
flashing specifications.
