The Enclosure

Well, the prototype enclosure is finished and the FlexWire Adapter has a new home (see the photos below).

The front panel only has one lonely LED to show when power is applied, but the rear of the box is where all the action is. Each DB25 connector contains connections for two (2) 8-bit BCD ports.

• The top connector is wired to the VHF+ buttons in PSDR and the External Control matrices in DDUtil.
• The bottom connector is wired to the HF BCD file in DDUtil and is controlled by PSDR frequency and/or band status. Additionally, the port that is connected to the DDUtil macro function is on this connector.
  

Also, either one of these DB25 connectors can carry auxiliary power of +12, +5, +3.3vdc and ground for powering other devices if needed. The adapter is internally fused at 500ma so as to protect the Flex's internal fuse. I'll post the plug connections in a few days.

The +12v connector on the back can be used to power the adapter if the fuse is blown in the radio, but shouldn't be used otherwise.

The Amp+ connector is for amplifiers that have a auto power on feature requiring +12v such as the Quadra, Prometheus and others.

The ALC connector is intended to connect to the amplifiers ALC output. Much testing left to do on this yet.

Serious testing under full amplifier power will now begin.

More to follow.
