It is simple converter without redundant power supply. It has no alarm contact. Wide Power Supply voltage:
8-19VAC or 8-35VDC. DIN mounting. Multimode version only. Number of converters in cascade is limited.
Tested 4 optical links (8 converters) in cascade with no problem with communication. However "star"
topology is better to use.
Recommended settings
Use converter Baud Rate Setting to 250k if setpoint Comms setting: CAN bus mode is set to 32C in controllers:
Use converter Baud Rate Setting to 50k if setpoint Comms setting: CAN bus mode is set to 8C in controllers:
IMPORTANT: This device can extend total CAN bus length by 2000m (HD67181FSX only) using
optical link, but total length of metalic CAN bus must not exceed these values:
200 m if setpoint Comms setting: CAN bus mode is set to 32C in controllers
900 m if setpoint Comms setting: CAN bus mode is set to 8C in controllers
