This article outlines important aspects to consider when replacing a CANrepeater with a CAN‑CR device.
APPLICABLE PRODUCTS (Mandatory)
- CANrepeater (1.01.0063.xxx or 1.01.0064.xxx)
- CAN-CR1xx, CAN-CR2xx, CAN-CR3xx
- CAN/FD-Repeater Standard (1.01.0211.20000)
POSSIBLE CAUSES / ANSWER
Please consider the following differences when performing a replacement:
Connector Types
- CAN-Repeater and CAN-CR100 have screw terminals
- CAN-CR200 has DSub9 connectors.
- CAN/FD Repeater standard has Push-in connector
Termination Resistors
- CAN-Repeater 1.01.0063.xxx/1.01.0064.xxx:
Internal termination resistors can be enabled or disabled via solder jumpers
- CAN-CR200:
Internal termination resistors can be configured using DIP switches - CAN-CR100:
Internal termination resistors cannot be changed after purchase.
Devices are ordered with or without internal termination (for both CAN channels).
- CAN/FD Repeater Standard
Internal termination resistors can be configured using DIP switches
CAN Bus Types

- CAN-CR devices
Support CAN High-Speed only.
Do not support CAN Low-Speed
- CAN/FD Repeater Standard
CAN High-Speed & CAN-FD. FRC-EP supports CAN Low-Speed
