Re: Error in AP driver

Pierre Henrotay

Hi Ray,

No: unfortunately, the value written by PulseGuide is _not_ retained
properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then change the
longitude via PulseGuide to E 5 50, then click "send to mount"
button, then power cycle then select location 1 again on the
Then I inspected the longitude: back to W 6 50 - so the value was
sent but not accepted.

I'd appreciate to have AP to check what is going on: I am now
thinking that the AP controller returns an incorrect string for east
longitude when the Gg command is issued.

Hi Pierre,

So it seems that the problem might be fixed by changing the keypad
to write in the range -180 to 180 instead of 0-360. I think because
Pulseguide writes in the range -180 to 180 the value is retained
after a power cycle.

as the AP protocol is extending the LX200, I read back the LX200
description (
<> )
This indicates the presence of the sign, and that East longitudes
negative (so -180 to 180 is the expected range).
The trace from ASCOM - and the log from PulseGuide both show a
near 360 (but wrong: 355*50 for E 5 50).

Okay, I guess the docs just left out the sign desination.

Thanks Ray

Hi Chuck,

Negative values work just fine in the test I just did.
