1 Overview

1.1 Attributes

•

Optical fiber based Ethernet/CAN router
for the connection of SafetyBUS p sub­networks

•

Powerful 32 bit microcontroller Sam­sung S3C4510B with CAN controller
SJA1000

•

Abolition of the extension/datarate re­strictions between two CAN bus
segments

•

Optical fiber extensions up to 15/40 km
possible (2 different device types)

•

Automatic detection of the used
baudrate

1.2 General Description

The rail mountable router SBR-FX/RMD trans­mits data between SafetyBUS p networks
using optical fiber. To achieve the connection
two devices are linked back-to-back, the trans­mission protocol used on the optical fiber is
the UDP/IP protocol. The use of UDP/IP abo­lishes the length/datarate restrictions between
two CAN bus segments. Depending on the
type of the device, extensions up to 15km or
40km are possible.

SBR-FX/RMD automatically detects the baud
rate on the controlling side. The I/O side can
be run with the baudrate detected on the con­trolling side or an independently customized
baudrate.
