Operation can be verified by four methods: Viewing the LCD screen on the device, using the
375/475 Field Communicator, using the 1420 Wireless Gateway’s integrated web server, or
using AMS
™
Suite: Intelligent Device Manager (or other compatible HART-enabled host).
Refer to Step 3: Communications and Configuration for details regarding each method.
If the LCD is installed and enabled, during normal operation, the LCD displays the measured
values at the configured update rate. Every time the CSI 9420 device wakes up to make a
measurement it displays these screens and then takes the measurement. Refer to the CSI
9420 User’s Manual for error codes and other LCD messages.
Press the Diagnostic (DIAG) button once and the CSI 9420 will cycle through display of the
TAG, Device ID, Network ID, Network Join Status and Device Status screens, then make
a measurement. Pressing the DIAG button causes this information to be displayed even if
the LCD is disabled for normal operation.
NOTE: To access the DIAG button, remove the front cover of the CSI 9420.
The Network join status as displayed on the LCD is shown in Figures 4 for the 2.4 GHz and
Figure 5 for the 900 MHz versions. Prior to configuring the device to join a network, it will
remain in the Network Search mode.
