Does anyone have the pinouts for the various temperature probe, fan, and heater connections on the scope? I'd like to build a heating/cooling control box for the scope with a humidity sensor that will do a better job than the (very expensive) EFA + Delta-T combination, but I don't have the scope yet to test the pinouts myself.

Hi Kyle,
If you haven’t received your scope yet, have you considered asking PlaneWave to wire your CDK for the Series 5 controller? That box does what the combination of the EFA + Delta T does, at half the price.

AFIK, the series 5 controller has no Hr sensor. Moreover it is only compatible to series 5 focuser (5x the price of Hedrick), which is totally overpriced, and not compatible to the Hedrick focuser. Last but not least it runs at 24V and not 12V, which is a serious drawback. IMHO, Series 5 gadgets are only reasonable for Delta Rhos. It is the continuation of a faulty concept in my point of view.

I'd much prefer a $40 box I can easily build myself, with 12v power, a reliable circuit board with good power management not prone to shorting, light weight, and a humidity sensor, which the Series 5 seems to still lack so far as I can tell.
I have a PW CDK 14 and was also considering replacing the overpriced ($750), closed source and failure prone Delta-T with a $25 Arduino that I can program myself. At this point I am controlling the fans and heaters with a Pegasus PB V3, but I am missing the access to the scope internal temperature sensors, so I cannot have a closed loop control. The temperature sensors are connected to an RJ12 connector.
If somebody knows the type of temperature sensors used in the CDK14, I am happy to look at the spec sheets and try to reverse engineer the RJ12 pin out.

The temperature sensors are DS18B20. That would be awesome if you could figure out the pin outs!

You don't really need to pair the series 5 controller mandatorily with a series 5 focuser (IMO, the Hedrick focuser is kinda junk anyway). Most people use either an Optec Gemini or a Moonlite Nitecrawler WR35 from what I gather. I had the option to wire mine with the series 5 controller (only) completely orthogonally to my Optec Gemini, but I didn't go with that option due to logistical challenges.

Same did I. Kicked out the Hedrick and got a Gemini.
I haven't been able to determine the pinouts, so I haven't yet been able to design a better thermal management solution. I'd still like to do so if I acquire a CDK14.

I've determined the pinouts for my CDK12.5. I'm not sure if they're the same on other CDKs. I'm currently working on developing a stand-alone system that can read all the temperature sensors (both via the EFA port and the Delta-T port), use humidity data from an attached sensor, and control both heaters directly, eliminating the need for both boxes and replacing them with a much less expensive single device in a much smaller form-factor. If anyone is interested in giving me feedback on what they'd like to see in such a device if it were to become more generally available please message me directly.
