CS-310 cable switch connector

Does anybody know the connector pinout for this Pentax wired remote? Has anyone come across a 3pin to 4 pin adapter cable? Like many, I have a 3rd-party 3 pin intervalometer, that works with my K-5. I'm attracted to the K-70, but the wired remote is a bit of an issue. I know there's one discussion post in this forum, but no solutions.

I see, from trawling around, that it uses a 4 pin jack plug. Is it a simple matter of wiring up an adaptor cable, or is there some other wizardry in the CS-310?

Welcome to the Pentax Forums!

You are correct. The CS-310 is not yet widely available in N. America. A few vendors in England have them, but I don't believe any purchasers have published the pin-outs and voltages.

Welcome to the Pentax Forums!!!

Thanks for the video with the pin-outs and a suitable donor remote. The OP for this thread has since posted the pin-outs on another thread.

Hello,

Just come my order of 3.5mm Male to 2.5mm Female Plug adapter (Stereo Audio Headphone Jack Adapter Converter) to convert my old third party cable release Yongnuo RS-802 (replacement of CS-205) to works as Pentax CS-310.
Bought from Ebay for less than 1 USD and works flawless, but need waiting for one month of shipping time.

CS-310 cable switch connector -- modified

New to the forum and so first posting. Purchased K-70 early fall 2018. Have k20d and had purchased a pentax wired cable shutter release for it. The male connector is 2.5mm. So went to Radio Shack/The Source and got the 2.5mm female to 3.5mm male audio connector. Works like a charm on the K-70. My cost about $5.00 Cdn. Just thought I'd share.
