Note: For additional CAN information, refer to the CAN Networks manual (
MAN0799) on our website.
6.1 Overview
All RX-371 OCS models provide a CAN networking port, which is implemented with a 5-pin connector.
The connector is labeled NET1.
Figure 6.1: NET 1 Connector
Like the MJ1 serial port, the NET1 port can be used for RX-371 OCS programming by connecting it to the
CAN port of a PC running Cscape. The NET1 port also allows the RX-371 OCS to exchange global data
with other OCS/RCS controllers and to access remote Network I/O devices (SmartStix Modules).
6.2 Port
Description
The RX-371 OCS NET1 port implements the ISO 11898-2 physical layer and the CAN 2.0A data link
layer standards. Also, since the NET1 port is powered by an internal isolated power supply, external
CAN power is not required.
6.3
CAN (NET1) Port Wiring
This section shows how the CsCAN port pins are assigned.
Figure 6.2: CsCAN Port Connector
Note: The V+ connection is not
required on the RX-371 OCS.
The RX-371 OCS network port is
self-powered. Supporting devices
can require this connection, and
this pin can be used to land the
extra wire required for those
devices.
