Trakbox problems Pse help!

[Francisco Costa <nop06152@xxxxxxxxxxxxxxx>]

Hi

I'm just starting on pacsat's, but even it looks like 
everything is proper connected and configured, I'm having a problem:
when Wisp ask Trakbox to aim the rotators, ocasionally Trakbox
doesn't seem to reply and the "The rotator has timed out" message show
up.
It ussually happens after a couple sat pass's.
If then I use a terminal program and start tracking any bird,
it works normally.
Also, but no so frequently, Trakbox set a wrong freq on the rig.
Like main vfo: 435000  sub vfo: OFF 

Could one thing be connected to the other???
Is it a configuration, a hardware or a comunication problem???

Any help will be much apreciated!
Many thanks in advance!

     Trakbox 3.40 and a Kenwood TS-790A (directly conected to trakbox)
