Handheld Communicator
This section covers a subset of the functions available with HART
®
. For a complete description
refer to Chapter 4 Using the Digital Interfaces . If the SVI II AP is not equipped with optional
pushbuttons and local display the checkout and configuration is performed using the
standard HART
®
communications interface. In addition to the functions performed with the
local pushbuttons additional functions are performed with HART
®
. For example, the
instrument tag descriptor is written and stored in non-volatile memory and used for point to
point wiring checkout.

Communicator Connections
Be sure that the configuration lock jumper is in the unlock position. When the jumper is in the
lock position (shorting the two-pin header) the handheld is not permitted to make any
changes. However, parameters are readable. If fault messages appear, they must be handled
before proceeding with HART
®
communications. Before communications proceed all error
messages must be cleared. For example, the following message is displayed if the instrument
has been serviced and the air is not connected.
