Configuring the Channel for DH+ Communication

		If you select the baud rate as 230.4 kbps, and you are using
	IMPORTANT
	IMPORTANT	the serial port or a PLC-5 coprocessor, use channel 2 for


		better overall system performance.

For proper operation, terminate both ends of a DH+ link by using the external resistors shipped with the programmable controller. Selecting either a 150Ω or 82Ω terminator determines how many devices you can connect on a single DH+ link.

If Your DH+ I/O Link Operates at	Use this Resistor
	Rating

230.4 kbps	82Ω

57.6 kbps or 115.2 kbps	150Ω

Depending on the controller you are using, you can configure these channels:

Controller		Channels that Support DH+
PLC-5/11		1A

PLC-5/20		1A (fixed DH+), 1B

PLC-5/30	PLC-5/20E	1A, 1B
PLC-5/40L PLC-5/40E
PLC-5/60L PLC-5/80E

PLC-5/40		1A, 2A, 1B, 2B
PLC-5/60
PLC-5/80

		To define the DH+ address and baud rate for channel 1A,
	IMPORTANT	To define the DH+ address and baud rate for channel 1A,
	IMPORTANT	you must set switch assembly SW1 on the controller;


		you cannot set this node address through the programming
