SUB-D9 Connector

The following figure shows the pins on the CANopen bus connector:

NOTE: Use an external CANopen line termination in your system wiring.

Pin Assignment

The table describes the pins of the CANopen bus connector:

Pin	Designation	Description
1	N.C.	Reserved
2	CAN_L	CAN_L bus line (Low)
3	CAN_GND	CAN 0 Vdc
4	N.C.	Reserved
5	CAN_SHLD	Optional CAN shield
6	CAN_GND	CAN 0 Vdc
7	CAN_H	CAN_H bus line (High)
8	N.C.	Reserved
9	N.C.	Reserved
N.C.: Not Connected.

Although the cable shield is connected to pin 6 (ground), it is still necessary to properly and externally ground the cable shield to your functional ground (FE).

WARNING
	UNINTENDED EQUIPMENT OPERATION Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Transmission Speed and Cable Length

Transmission speed is limited by the bus length and the type of cable used.

The following table describes the relationship between the maximum transmission speed and the bus length (on a single CAN segment without a repeater):

Maximum transmission baud rate	Bus length
1000 Kbps	20 m (65 ft)
800 Kbps	40 m (131 ft)
500 Kbps	100 m (328 ft)
250 Kbps	250 m (820 ft)
125 Kbps	500 m (1,640 ft)
50 Kbps	1000 m (3280 ft)
20 Kbps	2500 m (16,400 ft)
