Westrn Reserve Controls PUB 14.1 1. WRC-CANR-DF-DN User’s Manual Overview The WRC-CANR-DF-DN Fiber Optic CAN Bus Extender converts a copper cable medium CAN-Bus network to a fiber optic medium. The WRC-CANR-DF-DN is always used in pairs and, along with the fiber optic cable set, inserts a length of fiber media into the copper CAN Bus network. It typically is used to convert a section of the CAN bus to a pair of fiber optic cables.
Western Reserve Controls PUB 14.1 WRC-CANR-DF-DN User’s Manual • 2 green fiber transmit and receive LEDs 1.2. Basic Operation Two CANR-DF units are required for each application – a CANR-DF Type 1 and a CANR-DF Type 2. These are similar devices that must be used in matching pairs. It does not matter which type is placed in which position with respect to the network topology or other devices on the network.
Western Reserve Controls PUB 14.1 2. WRC-CANR-DF-DN User’s Manual Quick Start To quickly and easily install your CAN-Bus Fiber Optic Extenders in your DeviceNet system, follow the instructions below. For more details, see Section 4. 1. These units are used in pairs. You need a CANR-DF Type 1, a CANR-DF Type 2 and two (2) fiber cable lengths, terminated with ST male connectors. 2. Set the baudrate of each CANR-DF using switches 5 and 6 on the 6-position switch block SW1.

Western Reserve Controls PUB 14.1 WRC-CANR-DF-DN User’s Manual Green LED TXF is illuminated when data is actively transmitted out to the fiber link. Green LED RXF is on solid when its fiber cable is connected to the TX port of an active CANR-DF. This LED flashes when data is actively received from the fiber link. 4.3. DIP Switch Settings The WRC-CANX-XX Multiplexer has a 6-pole DIP switch. Switch positions 5 and 6 are used to set the baud rate. (Switch positions 1-4 are reserved for future functions.

Western Reserve Controls PUB 14.1 WRC-CANR-DF-DN User’s Manual 4.5. Network Cabling and Configuration This section provides general guidelines for connecting DeviceNet and SDS systems. You can find detailed specifications in the referenced ODVA DeviceNet and Honeywell SDS specifications. 4.5.1. Cable Lengths The following provide cable length limits for Devi ceNet and SDS systems. These numbers apply independently to each physical section of the network, whether it is copper or fiber.
Western Reserve Controls PUB 14.1 WRC-CANR-DF-DN User’s Manual in a trunk line, it must be terminated on side A. A terminating resistor is built into the CANR-DF, so that an external resistor should not be added. Drop line use: When CANR-DF is used in a drop line line (the Network A side is toward the main trunk), the Network A connection is not terminated. The user must remove the built-in terminator by clipping it out of the circuit.

Western Reserve Controls PUB 14.1 5. WRC-CANR-DF-DN User’s Manual Operation CANR-DF receives and stores messages received at either network connection and actively retransmits the message while providing 2500V isolation between the two sections of the nework. The two bus connections for each CANR-DF are referred to as Network A (copper wire), and Network B (fiber optic cable), but they are the same logical network with isolation between them. To extend the maximum distance that a network.
