Otter box is 11 bucks and they come in clear so you can see the lights (key to knowing radio issues)
You could mount a short 9 pin cable in the box so not to much fab going on and would be water proof .

The Bow Tie Surveyor,

Wow, good detective work. That is a AP-L1, now you know why I wanted to light up the load. Great robot, but heavy.

Hi there, everyone!  This is my first post from the Philippines. I know that this topic is already old, but to me, it is my need, because I would like to revive my Topcon APL1, but this time, converting satel radios into parani bluetooth setup.  That is, if somebody out there  can help me in the setup.

@digong  Did you set up your APL-1a with Parani? I am trying to do this.

Still trying to find the data and power connectors. I am not going to give up and will let you know the progress.
