Installation and Wiring

PRD mode prevents the NetLinx program stored in the Master from running when you power up the NXC-ME260. 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 in PRD mode and use the NetLinx Studio 2.1 program to resolve the communication and/or control problems with the resident NetLinx program. Then, download the new NetLinx program and try again.

Think of the PRD Mode (On) equating to a PC’s SAFE Mode setting. This mode allows a user to continue powering a unit, update the firmware, and download a new program while circumventing any problems with a currently downloaded program. Power must be cycled to the unit after activating/deactivating this mode on the rear Program Port DIP switch #1.

It is recommended that the baud rate DIP switch be set prior to any installation of the NXC-ME260 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 and PRD Mode Settings tables above.

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 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 DIP switch positions according to the information listed in the Baud Rate Settings and PRD Mode Settings tables (page 5).
