Re: Connecting laptop to ST-4 input on GM8
|
Hi
One simple option to allow PHD2 to guide with the 492 controller (besides using a camera with an auto guider port as mentioned above) is to use a GPUSB adapter. This device connects to your computer via USB, and to your GM8 mount via the ST4 port (the HC port on the controller). I've used it for 10+ years without problem before moving to a GoTo controller with OnStep.?

the 492 digital drive unit ?has no computer connections.? However you can connect an modern ST4 autoguider and auto guide with the unit.?
What you do is remove the HC and plug in a 6p6c (6 pin/6connector) “y” adapter into the HC socket.? Then you plug the Guider and HC into this. ?
On the 492 front panel you have a button that can select G/S.? Guide speed. ?.3x, .5x, 2x, 4x, 8x, 16x this is the rate any HC or ST4 autoguider signal will move the Ra axes at for corrections.?
This shows the .
This shows a .
Another view of them. ?
You can probably find one cheap. Losmandy has s a manual about the . ? Have a read ??
One think that camera that camera The isn’t an ST4 output camera.? You cannot use it to guide the GM8 directly.? You may be able to use a Interface.? You can also use it in USB as a guider but it has no ST4 output format
? Sorry you need a different guider ?or The shoestring interface should work ? I’ve never used on but others say it works ?kinda complicated it somewhat as you then need a laptop to use the USB just to get ST4! ? St4 was standalone ??
?
I recently repaired a 482 DD unit and sent the user a document on all this recently ? I can send you a copy if you email me ? I’ll need your email address. The. 492DD Units are nice decent units.? Yes they have limitations like no goto and sow slew rates (16x sidereal max) but it’ll return good service and will guide just fine as said.?
cheers
