3.
Remove the two screws that hold the front plate on the Master Card, and remove the front
plate.
4.
Align the edges of the card with the guide slots inside the Master Card slot on the NXF or NXI.
5.
Slide the card about halfway into the slot.
6.
Inside the Master Card slot on the NXF or NXI, find the 6-pin control cable connector.
7.
Plug the connector from the NXF or NXI into the 6-pin terminal on the Master Card. This
connector is keyed to ensure correct orientation.
8.
Once the control cable is connected, gently slide the card all the way in until you feel the rear
edge of the card lightly snap into place.

Re-apply power and other connections as necessary.
Replacing the Lithium Batteries
The NXC-ME260 is equipped with two lithium batteries (FG# 57-0013) that have a life of
approximately 5 years to protect their memory. When DC power is on, the batteries are not used.
When replacing the batteries, remove one at a time to avoid losing the program in memory.
1.
Discharge the static electricity from your body by touching a grounded metal object.
2.
Unplug all the connectors from the Controller or Module.
!
NetLinx Integrated Controller (NXI): Remove the rear panel from the NXI. Then,
disconnect the NXI control cable and remove the Master Card.
!
NetLinx Module (NXM-xxx): Remove the rear panel from the Module, and remove the
Master Card.
3.
Carefully slide one battery out of its socket, and insert the new battery.
4.
Plug the 2-pin PWR (green) connector to reapply power. Wait approximately 1 minute. Then,
remove the PWR connector again.
5.
Carefully slide the other battery out of its socket and insert the new battery.
6.
Replace the Master Card (re-connect the NXI control cable to the Master Card if replacing in
an NXI).
7.
Replace the rear panel and secure with the mounting screws; reconnect all control,
communication, and power cables.
