Troubleshooting Device Connectivity
If your FieldDAQ device becomes disconnected from the network, open MAX and try the
following:
•
After moving the device to a new network, NI-DAQmx may lose connection to the
device. In this case, click
Reconnect
to provide NI-DAQmx with the new hostname or IP
address.
•
The FieldDAQ device icon indicates whether it is recognized and present on the network.
If a connected device appears as disconnected in the configuration tree in MAX, select
Self-Test
or
Reset
. If successful, the device icon changes to dark grey.

Reserving the Device in MAX
When the FieldDAQ device is connected to a network, multiple users can access the device.
To perform any DAQ functionality on the device, including reset and self-test, you must
reserve the device in MAX. In MAX, an unreserved device or device reserved by another host
appears with an X and a reserved device appears as dark grey. Only one user at a time can
reserve the FieldDAQ device.
If the device was not reserved automatically after it was added (
Add Device
), you can reserve
the device in MAX by expanding
Devices and Interfaces
»
Network Devices
, selecting the
device, and clicking the
Reserve Network Device
button. The Override Reservation dialog
box opens when you attempt to explicitly reserve a device. Agreeing to override the
reservation forces the FieldDAQ device to be reserved by the current user.
STATUS LED
The FieldDAQ device has a STATUS LED.
