CSI 9420
Begin by removing the power module-side housing cover. This will expose the
terminal block and HART communication terminals. Connect the power
module to supply power for configuration. This process is illustrated in Figure
2-2.

For configuration, the CSI 9420 will receive any HART communications from
a handheld Field Communicator, AMS Device Manager, or other
HART-enabled host. When using a Field Communicator, any configuration
changes must be sent to the transmitter by using the Send key (F2). AMS
Device Manager configuration changes are implemented when the Apply
button is clicked.
NOTE:
The CSI 9420 enters “HART Listen” mode for communication on the wired
interface. When doing so, “HART Listen” is displayed on the optional LCD, if
installed. A finite amount of time is required to enter this mode and the device
is unable to do so during its boot sequence or while performing its real-time
vibration measurement. For this reason, it may be necessary to “retry” the
initial wired HART handshaking sequence. If repeated attempts to establish
wired communication fail, you can force the device into HART Listen made by
removing the front cover and pressing the “CONFIG” button once. Pressing
the CONFIG button a second time causes the device to exit HART Listen
mode. Once the device has entered HART Listen mode, it will remain in this
mode until the CONFIG button is pushed, power is cycled, or no activity is
seen on the wired interface for three (3) minutes.
The basic steps for configuring the CSI 9420 are as follows:
