Cable, ILEC SN-10 (S/N: > 99) to Instrument Panel, PS-5a and Garrecht Volkslogger (with RJ connector)
This cable is designed to enable a PDA (Pocket PC or Palm device) and an SN-10 to be connected to a Garrecht Volkslogger.  It replaces the ILEC "Cockpit Panel Cable".  It includes all the connections found in that cable.  5 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 "GPS Input" switch that is used to select whether PDA or SN-10 data is sent to the Volkslogger.  This is necessary because either unit can send task declarations to the Volkslogger.   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).  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 the PS-5a power converter (which sends power and data to the PDA).  A 1 m (39.4") cable goes to an RJ connector for the Volkslogger.  This will not work with older Volksloggers that have round connectors.  This cable provides data and power to the Volkslogger.  Power for the Volkslogger comes from the switched output on the SN-10. 

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. 

GPS Input Switch Positions

• "SN10" - Used to send task declarations from the SN-10 to the GPS.
• "PDA" - Used to send task declarations from the PDA to the GPS and for flight log downloads to the PDA using ConnectMe or pocket*StrePla-Connect or VL to IGC.

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 "GPS-Output" 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.
