Fiber-Optic CAN bus

Extenders

WRC-CANR-DF

WRC CAN bus Extenders boost signal levels, allowing longer cable lengths, longer trunk

lines, and longer drop lines without sacrificing network speed. CAN bus Extenders permit

maximum network speed and throughput on CAN, J1939, or DeviceNet network devices,

resulting in better control of the process. In addition extenders require no configuration

when used in DeviceNet applications as they are configured for autobaud operation.

Key Features:

♦ Expands the usable applications for DeviceNet, J1939, SDS, and other CAN

V2.0, Part A and Part B compatible CAN bus systems

♦ Enables the creation of star, tree and other non-linear network topologies which

increases flexibility in system design and reduces installation costs

♦ Works with both trunk lines and drop lines

♦ Allows operation at higher speeds for specific distances

♦ Fiber-optics provide superior electrical interference protection versus copper cables

♦ Operates at 9.6K to 1M fixed baud for J1939 or CAN bus networks

♦ Auto-detects baud rate on DeviceNet (125k, 250k, or 500k baud)

♦ Isolates the two sections of the CAN bus (copper wire)

♦ Extender operation is transparent to Master and Slave devices

♦ Powered from the CAN bus network

♦ Sealed NEMA-4X enclosure

♦ Standard round, mini-style connector with male pins for copper cable

♦ Standard Fiber Optic ST female connector for use with multi-mode or single mode fiber

♦ Standard CAN chips manage CAN bus error detection and handle message bus arbitration

♦ Less than 900 usee latency

♦ Termination resistor built in on the CAN bus interfaces

♦ Two identical WRC-CANR-DF units are included in an order kit and both are required for each application

Series IV CANR Enhancements include:

♦ Up to 12km fiber lengths

♦ CAN 2A, CAN 2B, and remote frame support

♦ Expanded DIP switch settings allow selection for CAN bus speeds up to 1M baud

♦ Enhanced autobaud operation

♦ Either unit in a pair can Autobaud from the other units defined baud rate

♦ Improved Reverse voltage protection and CAN line noise immunity

♦ Increased message internal buffers - Automatic Memory Technology (AMT) operation

♦ Eliminates the distinction between WRC's earlier version Type 1 and Type 2 CANR
