Hi Group,

I have finally order the fibre glass pole from Moonraker of all places and
am awaiting its replacement after being damaged in post!

Anyway, I have also received and played with my new shiny LVB tracker to
interface to the G5500 and have a couple of questions that may you guys
could help me with!

a) I have calibrated the rotator with the G5500 and it would appear at 0
degrees on the LVB tracker, the control box is at 0? If I use the controls
on the control box it moves about 2 degree to the stop point. Is this normal
or have I missed something as I have recalibrated several times!

b) The tracker has a USB interface and uses a virtual serial port to
communicate with, but it seems to disconnect quite a lot when using NOVA
during the testing?

c) What are the recommended settings for NOVA as I am not sure I understand
them 100%! I know it uses the G232A command set and does control the
rotator, but I am not sure I have set the interface section correctly.. Do I
set the maximum azimuth to 450 and leave the azimuth setting to 0-360?

Sorry for the questions, but I know how to use it once its been working,
just never had to create all this from stratch.

I have checked the archive on AMSAT-BB and not found much to help, although
some hints to actually get the rotator talking did come from the group!

Many Thanks,
