Work in progress set of tools to use the Nikon DataLink remote control protocol present on the Nikon N90/N90s (F90/F90x).

Install the libserialport (https://sigrok.org/api/libserialport/unstable/index.html) lib on your computer, then checkout the repository:

git clone --recursive https://github.com/rhaamo/pikon/
# or
git clone https://github.com/rhaamo/pikon/
cd pikon
git submodule init
git submodule update

Using GCC:

make

Using Clang:

make CC=clang++ CXX=clang++

• Nikon INQUIRY (camera identification)
• 9600bps switch (check is deactivated, but the switch works)
• Fire shutter (tested on N90s)
• Settings retrieval:
  • only the first setting (see broken)

• Sending focusing command (does nothing, sessionError)
• Everything else
• sending multiple sendCommand (settings/status retrieval) only the first one works
• Settings retrieval
  • iso, focale, etc. everything returns 0 ???

• Focus, commands, etc. (might be N90s only, waiting to receive it for testing)
• Export of the 'exif-like' datas (the memo I think)
• Setting various camera infos (exposure, ISO, etc.)
• Library should return custom structs with raw and human values alongside

See the folder docs/.

• Text files about the DataLink protocol (packet format, etc.)
• N90 Buddy for Palm Souce source code for a PalmOS 3.x app

Example doing camera identification (N90) and triggering the shutter.

You don't need the Nikon DataLink cards, they were designed for old Sharp Organizers.

The 10 pin connector exposes serial, 1200bps 8n1 with 9600bps negotiation possible.

Pinout is here: http://www.avernus.com/~gadams/photography/nikon/datalink-protocol/MC31.pdf

Front view from the camera, you need to wire pin 5 and pin 4 to TX/RX and pin 6 (or 7) to GND, directly to a FTDI and that's it. (no need for pin 3 ! RX/TX/GND are sufficient.)
