Slow response from EQMOD
Posted 10 September 2012 - 05:02 PM
I have been hearing great things about EQMOD so I downloaded it & the ASCOM software on my Toshiba laptop last week.
The install went so so (couple of minor gliches) but everything started up and some daytime test showed that the software worked.
However - When I click on any icon in the EQMOD window, there is no response until about 7-12 seconds. Likewise, when I release the mouse button, it takes several seconds until the release is noted.
I have the same slow response when I use a usb-connected game pad.
Next step: I fired up The Sky6 and set Telescope API/EQMOD as the telescope controller and connected. Again, slews are good and accurate, but the response time is 7-12 seconds.
I suspended the scope connectivity and changed the 'scope controller in The Sky6 to Celestron-5 etc and the response to slews was immediate.
So the hardware, cables etc are good.
I then suspended the 'scope, changed back to Telescope API/EQASCOM and re-established the 'scope connection.
The response is immediate now to both the hand controller and the mouse controls using EQMOD. Something about first selecting the Celestron driver seems to set a needed parameter.
I powered everything off (laptop/scope etc) and started over again. If I initially connect to the mount using The Sky6 and use the Celestron 5 as the scope interface, make a quick slew, then change to EQMOD as the interface, everything work just fine all night.
I have done this every night for a week now, so it's not a one time event.
In addition, I also tried using POTH as the mount control, and set the driver to EQMOD. Same results.
My laptop uses a Belkin USB-Serial adapter. Used it for a long time, never any issue with it with other devices. I use the RJ serial connector in the Atlas hand controller, and switch to PC Direct when using EQMOD, and escape out of PC Direct when switching to the Celestron drivers.
I can live with this, but would rather not. Anyone else see this?

I did re-installs on the ASCOM and EQMOD software. No change.

Really surprising since it works with everything else I use it with, but it looks like there are delays in the drivers that keep it from reliably working with EQMOD.
Also, the group has a database of known working serial adapters. Keyspan (which Rod mentions above) is known to work.

Replacing the Belkin USB-Serial adapter with a Keyspan (made by Tripp-Lite) USB-Serial adapter resolved the problem. All communications between the mount and EQMOD are fast with no problems.
