Setting the Conf iguration DIP Switch (for the Program Port)
Prior to installing the Controller, use the Configuration DIP switch to set the baud rate used by the Program port for
communication. The Configuration DIP switch is located on the front of the Integrated Controllers.
NOTE: While the NXC-ME260/64 is capable of receiving 8 and 9 bit characters, it cannot receive 7 bit, 1 stop bit data from a serial
device (ex: 9600,N,7,1).
It is recommended that the baud rate DIP switch be set prior to any installation of the NXC-ME260/64 card.
1. Locate the red baud rate DIP switch (FIG. 4).
2. Set DIP switch positions according to the information listed in the Baud Rate Settings on the Conf iguration DIP Switch table
and PRD Mode Settings table.
If the card has already been installed:
1. Disconnect the power supply from the 2-pin PWR (green) connector on the Master Card.
2. Unsecure the NXC-ME260/64 by unscrewing the two faceplate securing screws (on both sides of the faceplate) using a
Phillips-head screwdriver (FIG. 4).
3. Carefully slide-out the card and locate the red baud rate DIP switch (FIG. 4).
4. Set the internal DIP switch positions according to the information listed in theBaud Rate Settings on the Conf iguration DIP
Switch and PRD Mode Settings tables (page 8).
5. Place the Master card back into its' housing and secure the two faceplate securing screws.
6. Reconnect the 12 VDC power supply to the 2-pin PWR connector and apply power.

Baud Rate Settings

Before programming the on-board Master, make sure the baud rate you set matches the communication parameters set on both
your PC's COM port and those set through your NetLinx Studio. By default, the baud rate is set to 38,400 (bps).

NOTE: Note the orientation of the Conf iguration DIP Switch and the ON position label. DIP switches 2,3, and 4 must remain in the OFF
position at all times.

Program Run Disable (PRD) Mode

You can also use the Program port's Configuration DIP switch to set the on-board Master to Program Run Disable (PRD) mode
