Configuration Mode Operations

With power applied to the aviation rack and the 400W Series unit turned off, press and hold the ENT key
and turn the unit on. Release the ENT key when the display activates. After the Data Base and
Instrument Panel Self-test pages, the first page displayed is the MAIN ARINC 429 CONFIG page. While
in Configuration Mode, pages can be selected by ensuring the cursor is off and rotating the small right
knob.
To change data on the displayed Configuration Page, press the small right knob (CRSR) to turn on the
cursor. Rotate the large right knob to change between data fields. Rotate the small right knob to change
a field that the cursor is on. Once you have made the desired selection, press the ENT key to accept the
entry.
The Configuration Pages described in the following sections are in the order found when rotating the
right small knob clockwise starting at the MAIN ARINC 429 CONFIG page.
The configuration pages shown here reflect main software version 4.00. Some
differences in operation may be observed when comparing the information in this manual
to later software versions. All configuration pages shown apply to the GNS 430W, but
not all apply to the GPS 400W or GNC 420W. Those pages and fields that apply only to
certain 400W Series units are denoted as such.
If any changes made in configuration mode are done on ARINC 429 or RS-232 pages,
the unit must be reset for the changes to take effect. This is accomplished by powering
the unit off and then back on.
