Gary Kopff here from Wildcard Innovations, the manufacturers
of the Argo Navis DTC.
In extensive testing we have performed, Argo Navis operates completely
reliably with Sky Safari.
I will provide a summary here for future readers plus some tips
which may prove useful not only for Sky Safari users who
connect to Argo Navis but also to users who connect to other
devices such as real Meade and Celestron telescopes.
On the Argo Navis side, determine which serial connector you
will be using, either SERIAL 1 or SERIAL 2.
Using the MODE SETUP, SETUP SERIAL dialog for that port, select
a BAUD rate of 9600 and a STARTUP command of meade.
EXIT out of the SETUP SERIAL menu so that any changes are saved
in non-volatile memory. Now power the Argo Navis unit OFF and then
ON. This will then ensure that the protocol selected in the
STARTUP menu then starts on that serial port.
On the Sky Safari side, use the Telescope Setup... menu.
On the Connection pulldown select your serial device.
We recommend the Keyspan USA-19HS USB Serial Adapter.
On Readout Rate, choose as desired (we use 10 per second).
*Do not check* Set Time & Location. Argo Navis is designed
to invalidate any alignment should the date, time or location change
and setting this box will cause Sky Safari to transit these
parameters to the Argo Navis which is not desired.
Argo Navis has its own time-of-day clock backed up with a lithium
For Scope Type: select Meade LX-200 Classic.
For Mount Type: on your Dob, choose Alt-Azimuth Fork.
Then select the Connect button at the bottom right of the menu.
After a second or so, the Scope Control dialog should pop up and
Sky Safari will play a connect chime. The bulls-eye target should
also appear on screen.
We have tested the above continually operating for over a 100 hours
at a time and it provides for a completely reliable connectivity
solution. If powered by a reliable power source, no resets or
loss of alignment should ever occur. If the unit had been aligned
and if after selecting Connect and then choosing an object
in MODE CATALOG a NOT ALIGNED message appears, this will because
the Set Time and Location check box in Sky Safari has been
inadvertently set. If the unit is powered by internal batteries
and the unit performs a power on reset or multiple power on
resets, this is simply an indication that the internal AA cells
are depleted and require replacing.
When using the Meade protocol, Sky Safari assumes you are connected
to a real Meade telescope which has a fixed Baud rate of 9600.
Though Argo Navis can operate with higher Baud rates, the Sky Safari
dialog has no selection for changing it and implicitly assumes it
is 9600. So you should therefore choose 9600 on the Argo Navis side.
