6.1 Overview
Some XLe/XLt models (XE1xx) provide a CAN networking port, which is implemented with a 5-pin
connector, labeled NET1.
Like the MJ1 serial port, the NET1 port can be used for XLe/XLt programming by connecting it to the CAN
port of a PC running Cscape. The NET1 port also allows the XLe/XLt to exchange global data with other
OCS/RCS controllers and to access remote Network I/O devices (SmartStix Modules).
6.2 Port
Description
The XLe/XLt 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 Wiring
Figure 6-1 and Table 6.1 show how the NET1 port pins are assigned.

Pin Signal Signal Description Direction
1 V- CAN Ground
−
2 CN_L CAN Data Low In/Out
3 SHLD Shield Ground
−
4 CN_H CAN Data High In/Out
5 NC No Connect −
Note: The V+ connection is
not required on the XLe/XLt.
The XLe/XLt 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.
CAN Connector
Use the CAN Connector
when using CsCAN network.
