[amsat-bb] Re: sprint 2 tnc hooking dilemma

[Malcolm M. Preston]

Nader,

I haven't used mine in a while, but my notes show:

J2 - Pin 7 not grounded (not connected to pin 7)

SP5 - should be open

I believe if you check all jumpers to the Factory Configuration, 
Satellite Model, on page 17 you should have it right.

Good luck.
