[time-nuts] 747 Chronometer
Greetings To All, Please accept my apologies in advance if this is off-topic. I have just acquired an aircraft clock, which I've tentatively identified as coming from a Boeing 747. It's way cool looking and would make a perfect dust collector in my ham shack if I could only power it up. There is a multi-pin military-style twist-lock connector on the back, but no indication of what the pinout may be. The unit is identified as: CLOCK, 3 24 HOUR GMT ELECTRONIC MFD BY A.W. HAYDON CO. PRODUCTS NO. AMER. PHILIPS CONTROLS CORP. Cheshire, Conn. MFR'S. PT. NO. A15551-P1 I've searched the Net for technical documentation, but could only find the reference to the 747. Does anyone have any information about these clocks, or can someone point me in the right direction? Many thanks in advance.

Re: [time-nuts] 747 Chronometer
Sounds like you need to know more about the instrument power in a 747, perhaps starting with Boeing. You could be needing DC or AC in one or three phases, more likely at 400 Hz. OTOH, the VCR players for movies looked like stock items. The AC generators in aircraft are not likely to have the accuracy of ground-based power distribution, so the clock probably has an internal DC supply and a crystal oscillator. Can you open it up to do any tracing? Have you tried calling A. W. Haydon? They've been around for a while.

Most likely, the clock needs 5V for the internal lighting. Many aircrft clocks are mechanical, but some are lectrical and need 28VDC. -Original Message- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com]on Behalf Of Charles Rushing Sent: Thursday, May 21, 2009 1:45 AM To: time-nuts@febo.com Subject: [time-nuts] 747 Chronometer Greetings To All, Please accept my apologies in advance if this is off-topic.

Re: [time-nuts] 747 Chronometer
Hi Chuck, This is an electromechanical clock. Should just need 24V DC to operate and 5V (ac or dc) for lighting. I'll try to dig out connections for you. --- On Thu, 21/5/09, Charles Rushing crushin2...@austin.rr.com wrote: From: Charles Rushing crushin2...@austin.rr.com Subject: [time-nuts] 747 Chronometer To: time-nuts@febo.com Date: Thursday, 21 May, 2009, 7:45 AM Greetings To All, Please accept my apologies in advance if this is off-topic.

Re: [time-nuts] 747 Chronometer
Hi Charles: It's probably a standard connector. You need to look at it closely with a magnifying glass at all the surfaces for ID information. 99% of the time there's printed or engraved or moulded information that is enough to ID the panel receptacle. Then it's straight forward to find the mating plug. Figuring out the pin out is also not that difficult if you can open it up. I'm working on a major addition to my connectors web page to help do some of that. http://www.prc68.com/I/Conn.shtml Have Fun, Brooke Clarke http://www.prc68.com Charles Rushing wrote: Greetings To All, Please accept my apologies in advance if this is off-topic.

Re: [time-nuts] 747 Chronometer
Hi Charles, I had a dig, but could only find info on the current clocks that receive time info on an ARINC 429 serial bus, and an earlier hybrid LCD / mechanical model that needs an external 1PPS (I'd like one of those). I've never seen an aircraft clock that needed an external 60Hz signal. Unfortunatly Hayden have been bought up and no longer list instruments. Keep Googling!
