Re: Using the GTO keypad with the Mach2

I have the same power meter. Look at pictures of my Battery Box to power several astro devices and it shows power meter attached to the box.
It shows two ways to attach RigRunner to the battery box. First set of pictures show mounting RigRunner outside of battery box and this method is simple. Second set of pictures show mounting RigRunner inside of battery box and this method is more complicated and messier inside the battery box but looks cleaner from outside of battery box.

Yeah, I have one of these too. They’re great – and so simple once you’ve converted all your power cables over to PP.

I purchased the A-P Online Power meter some time ago
and have found it very useful.for assessing current draw under varying loads, balancing the scope, evaluating if something is binding somewhere, e.g. cable drag, remaining battery capacity.

Rolando, thank you again for all of the great information. You should put some of this in your specification (just a suggestion). I’ll be able to monitor it once I have a chance to connect the Mach2 to a battery since I have a shunt installed to monitor draw. I’ve never noticed the spikiness of the dew controller, but do know that they're pulse width modulated (not clear on frequency) and I currently use a simple 5A “brick” supply with my current setup that supplies everything (mount, heaters, camera cooler, focuser, USB hub, etc) when running at home. With the Mach2 and supplied 24V power, It’ll be easy to split the supplies by just keeping my current supply for everything but the mount. In the field I’ll be using a single 12V 55Ah battery. I assume the mount power input is separate from the supply that will feed through up to the DEC axis and the supply that powers the USB hub. I guess if need be, some additional decoupling can be added around the dew controller if it ever caused issues for other 12V components. Maybe this is why I sometimes get mysterious image transmission failures.
