5.1 Overview

QX models with either a BP41 or BP43 attached provide a CAN networking port, which is implemented

with a 5-pin connector, labeled CsCAN.

Like the MJ1 serial port, the CsCAN port can be used for QX BPxx programming by connecting it to the

CAN port of a PC running Cscape. The CsCAN port also allows the QX BPxx to exchange global data

with other OCS/RCS controllers and to access remote Network I/O devices (SmartStix Modules).

5.2 Port Description

The QX BPxx CsCAN port implements the ISO 11898-2 physical layer and the CAN 2.0A data link layer

standards. Also, since the CsCAN port is powered by an internal isolated power supply, external CAN

power is not required.

5.3 Wiring

This section shows how the CsCAN port pins are assigned.

Figure 5-1 – CsCAN Port Connector

Table 5.1 – CsCAN Port Pin Assignments

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 QX BPxx.

The QX BPxx network port is

self-powered. However,

supporting devices can

require this connection, and

this pin can be used to land

the extra wire required for

those devices.
