So I've got this clock that has white neon around the face. It has separate 110V plug for the neon but in the factory it was controlled. Attached are some pictures of it. I'm looking to get it going again. It's about 2 feet in diameter and they were in multiple factories. The brand is Lumichron. See the pics. The control is two wires. I'm thinking 12V with a coded signal but I'm not sure? Anyone recognize the connector and how you control/power these? It's white neon around the face. I'll post more pictures of the front later. This is the timing connector. The other white cable just powers the neon. Bill

Lumichron indicates it is a 24V impulse: https://lumichron.com/wp-content/uploads/Wiring-Diagram-typical-.pdf But it is not obvious how a 24V impulse would allow the clock to be adjusted to GPS time after power loss. And it seems like a really simplistic impulse per minute according to https://lumichron.com/wp-content/uploads/Specifications-Section-10-74-13-2018.pdf stating: "Slave-type, hi-torque, impulse-drive, 24v impulse control – shall move only once a minute. " Looks like they have a newer version using 4 wires: https://lumichron.com/wp-content/uploads/2019/07/wiring-diagram-tower-clock.pdf Here is a controller where it states the impulse is bipolar: https://lumichron.com/the-new-hn-60-and-hn-61-clock-controller-from-mobatime/ Possibly one polarity sets it to 12:00 and the other polarity advances it 1 minute? Don't know myself. Time to experiment with a 24V power supply? Good Luck!

Thanks a million Robert you gave me somewhere to start! I didn't want to jump without some research first. I figured it's 12V or 24V DC. These were all hooked to a master clock originally but was thinking Pi or Arduino but using a John M. TimeHat with a new Pi would be neat. Happy Thanksgiving everyone.

The connector is a AMP inc. 4 pin Mate-N-Lock connector. It is still available from Digikey and other distributors.

Oops, The connector is a AMP Universal Mate-N-Lock connector. The "Universal" Mate-N-Lock has the tabs on the side for strain relief. The original Mate-N-Lock did not have the strain relief.

Thanks Mike. I knew I'd get some hints here. I seem to remember there were a few simple protocols for these master clocks. Unfortunately it's just old enough that there aren't really a lot of docs to follow on the Internet. It can't be that complicated. With only two wires that also power the clock it has to be pretty simple. It may even hearken back to my elementary school days with the clocks that all clicked together then they were set from the master clock. I remember them all advancing one minute at a time until at the set time.

Synchronome is only one of the manufacturers involved and may be less common in the US than the UK, but as a keyword seems to provide a lot of related information on master / slave clocks. https://clockdoc.org/default.aspx?aid=80 On Fri, Nov 25, 2022 at 10:04 AM Bill Notfaded via time-nuts < time-nuts@lists.febo.com> wrote: > Thanks Mike.
