Cable, ILEC SN-10 (S/N: > 99) to Instrument Panel, SPS-1 Dual PDA Power Supply and Cambridge Aero Instruments 302 or 302A
This cable is designed to enable 2 PDAs (Pocket PC or Palm device) and an SN-10 to be connected to a 302A or 302.  It replaces the ILEC "Cockpit Panel Cable".  It includes all the connections found in that cable.  4 cables exit the back of the DB-9m connector that plugs into the SN-10.  A 0.5 m (19.7") cable goes to a DB-9f connector that is to be mounted in the instrument panel.  This connector is used for data transfers to the SN-10 from a PC and for connection of the SN10-R remote control unit.  A 0.5 m (19.7") cable goes to a DB-9f connector for connection to the SPS-1.  5V power is NOT taken from the 302 or 302A and made available to the PDA cable - the SPS-1 powers the PDAs.  A 0.5 m (19.7") cable goes to an DB-9m connector for the 302 or 302A.  A 0.5 m (19.7") cable goes to a "PDA Input" switch that is used to select whether GPS data goes directly to both the SN-10 and the PDA (for flight declarations and flight log downloads) or through the SN-10 to the PDA (for use in flight).  The transmit line on the PDAs is connected to the GPS receive line so that flight logs may be downloaded and task declarations may be uploaded.

New Version
In August of 2005 ILEC released a new version of the SN-10 firmware which can send receive data from a GPS, add ILEC wind and vario data to the GPS data stream and send all the data to a PDA.  Details are available here.  The updated cable can be used with both SN-10b units with old (firmware<2.31) or new (firmware >=2.31).  Due to the wiring change required to accommodate this new software feature, this cable has been re-designed to include a "PDA Input" switch.  Below is a summary of the switch positions. 

PDA Input Switch Positions

• "GPS/Declare" - GPS output is sent directly to both the PDA and the SN-10.  Allows the flight recorder to respond directly to the PDA to acknowledge task declarations or download flight logs.  Use only during task declarations and flight log downloads with SN-10 units with firmware version 2.31 or greater.  Used at all times with SN-10 units with firmware version < 2.31.
• "SN10/Fly" - The PDA receives GPS data from the SN-10. GPS output is sent only to the SN-10's "NMEA input" line.  The SN-10 adds SN-10 data to the GPS data stream and sends the data to the PDA. The SN-10's transmit line is connected to the PDA's receive line.  Use this position when in flight or when not doing a task declaration or flightlog download.

Old Version - no longer available
Previous versions of this cable split the GPS data and sent it directly to both the PDA and the SN-10.  No switch was used.

Using a Pocket PC for SN-10 Waypoint Database and Fight Log Transfers
It is possible to send waypoint files to the SN-10 from a Pocket PC.  You can also download flight logs from the SN-10 to the Pocket PC.  That way you don't need to bring a PC to the airport.  Details are available here.
