Lucent KS-24361
Some years ago a bunch of us bought a number of these Lucent KS-24361 unit pairs. Mine has been in storage till now, and I'm trying to bring it back up using old notes. So far I'm not getting anywhere and I was wondering if these things have maybe fallen foul of the 1024-week GPS bug? Anyone know? I guess my next step is to get the comms to it working regardless.

Hi
The 1024 week nonsense should simply make it put out a weird date. Otherwise
the the device (whatever it is) should be able to run just fine.

Here is a blog covering the Ref 0 and Ref 1 units using the assist of
an Arduino to make them work.

I’ve got one working fine thanks to assistance received here! You do need
to tell it current date and time over the SCPI interface to sort the 1024-
state, but while remaining powered up it should be fine. I added a battery
backup to the Oncore board to speed up startup in future after a power down.
I found it helpful to get the oncore board functioning on its own first
(you simply need a psu and rs232 to ttl adaptor). The winoncore software
still worked on win11 (found I think on KO4BB).
There are potential tantalum capacitor issues - and they may cause
collateral damage. I had to replace one and a transistor which had
self-decapped.

I had assumed (yeah I know) that this would do an automatic survey, which I think my Z3805A does. Uh, no. So, after giving up on my USB RS422 adapter, I used my one real serial port and the "pin hack" to talk to the thing and tell it do a survey. Things are finally progressing. I'm still uncertain about the 1024 week bug, though. During all the things I tried before I finally got comms going, I swapped out the UT+ V2.2 receiver for a UT+ V3.1. So if there was a 1024 week bug (which I saw on the receiver on my Z3805A when I got it) this would have fixed it - I think.
