NXC-ME260 NetLinx Master-Ethernet Card/Module

Installation and Wiring

This section contains information about configuring the PROGRAM port, installing NetLinx

Modules and the ME260, wiring diagrams, and pinouts for assembling cables.

Setting the Program Port DIP Switch

Baud rate settings

The Program Port DIP switch is located on the front of the Master Cards. For Modules, you must

remove the front panel to access the DIP switch.

Use this DIP switch to set the baud rate for the Program Port, according to the settings shown in the

following table. Make sure the baud rate you set matches the baud rate on your PC's COM port

before programming the Master Card. By default, the baud rate is set to 38,400 (bps). Note the

orientation of the DIP Switch and the ON position label.

Program Run Disable (PRD) mode

You can also use the Program Port DIP switch to set the Master Card to Program Run Disable

(PRD) mode according to the settings listed in the table below.

PRD mode prevents the NetLinx program stored in the Master Card from running when you power

up the Master Card. PRD mode should only be used when you suspect the resident NetLinx

program is causing inadvertent communication and/or control problems. If necessary, place the

Master Card in PRD mode and use the NetLinx Studio program to resolve the communication and/

or control problems with the resident NetLinx program. Then, download the new NetLinx program

and try again.
