[amsat-bb] FT736R cable

Here is the wiring of a serial interface


For usb to TTL  you need 5V TTL logic and presumably similar
connections and baud rates.

If you look on ebay you can see people selling them and the rig end
needs the right connector, a 6 pin DIN.

You connect the TX of the USB lead to the RX on the radio (pin3) and
the output of the rig (pin 2) to the RX on the USB converter and pin 1
to ground.

You probably don't need the pin 6 connection as the converter will be
supplied by the USB power.

Make sure to get a USB cable with drivers available for your current
operating system and ideally a common one so that drivers will be
available in many years time for future systems.

Ideally if you could afford it a fully isolated interface would be better.
