Damn, that's complicated. No wonder people are shying away from doing
this.

All you need is a scrap 4 wire telephone lead, a 7pin D Sub connector
and a couple of AA cells.

If you want to take the power from the brick then add an RJ-11 coupler
and use the supplied RJ-45 / RJ-11 cable.

Even if your computer doesn't have a legacy serial port most pilots
probably have a USB to serial dongle to support their other toys.

The display data output is +/- approx 5 volts and the input accepts
the signal from a standard serial port. Butterfly display manual
indicates direct connection to the PC serial port is acceptable.

I made my cable more complicated by providing the abilty to switch the
display data lines between the PC port and the Brick but that's not
needed.

A similar simple cable, without the power source, can be used to talk
to the brick using a standard PC terminal emulation program.
