AC 43.13-2A, aircraft manufacturers’ recommendations and FAA-approved technical
data.
Warning :
It is probable that radio interference will occur in the split mode when the frequencies of
the two aircraft radios are adjacent, and/or the antennas are physically close together.
PS Engineering makes no expressed or implied warranties regarding the suitability of
the PMA7000M-S in Split Mode.
2.8 Wireless telecommunications interface
The PMA7000M-S has interface capability with units such as the Trimble TrimConnect
3100 D. It is the user’s responsibility to determine the appropriate legal use of the
equiment, and provide the services.
Interface to the 3100 D is through the J1 (bottom) connector, pins 14 and N. Pin 14, la-
beled cellphone ring, is connected to pin V of the 3100D J3 connector and pin N of J1 is
connected to pin W of the J3 connector. On the TrimConnect interface these are listed as
data/fax lines, but they are used for voice interface in this case.
Use a 2-conductor with shield cable, and connect the shield to Pin M of the 3100 D J3.
If interface is desired with another type of wireless telecommunications unit, the aircraft
owner can purchase an after-market interface cable. By Federal Communications Commis-
sion (FCC) regulations, these can only be used on the ground in the United States.
Interface cables manufactured by AXCELL are available from Mobile Quest (800) 882-
1288, (215) 734-7000 phone, (215) 734-8000 fax. The following is a partial list of avail-
able interface cables:

Unauthorized use of cellular telephone devices in aircraft is subject to FCC enforcement action,
which may include a $10,000 fine per incident. PS Engineering, Inc. does not endorse using unap-
proved cellular telephone equipment in flight, and takes no responsibility for the user’s action.
2.8.1 Hook Switches
While the mic selector acts as the hook switch for the pilot, additional hook switches must
be installed to have full access to the cellphone system. The copilot hook switch is a SPST
switch that connects pin L of J2 on the PMA7000M-S to ground to place the copilot on
the cellphone.
