Introduced in
2006 was the XCOM remote head option which attaches to the RS 232 port on
the back of the XCOM radio, this is ideal for aircraft with tandem seating
or aircraft with side-by-side seating where they would like access to the
radio by both the pilot and co-pilot.
The connection
between the remote head and the XCOM radio is a simple cable allowing all
of the controls on either panel to duplicate themselves on the other panel
e.g. if the pilot in the front seat of the aircraft adjust the radio to
123.45 then the display in the rear also adjusts to show 123.45. If the
copilot in the rear seat makes any adjustments or changes to the remote
head it will also adjust the radio in the front seat. All of the XCOM
features can be duplicated with a remote head option.
