Hi, I managed to get one of these Lucent boxes from a local ham that moved away a couple years back. I finally got around to modifying it today with Skip Withrow's mod to add 10 MHz output. I connected an antenna and after a few minutes the yellow and No GPS and Fault LEDs go out and the green Online LED comes on. I put my scope on both the 15 MHz out and the new 10 MHz out port and get no output. Before I dig into this with my scope tomorrow night, is it as something as simple as a signal I'm missing to enable the outputs? I only have the antenna connected and two pins for 24 VDC, nothing else. Thanks for the bandwidth. Chris KD4PBJ

Hi If you only have one box, you need to be sure the “fake” connections on the interconnect are correct. If they are not, you will not get it to operate correctly. There also is a survey process if you have not had it running in your location before. That could take a few hours to a few days depending on your antenna.

Fake connections? Isn't a redundant system supposed to allow one box to be disconnected?

Hi One might *think* a redundant system would work fine with the plug yanked. In this case …. nope. It needs to have a dummy connector on it to get the device running. I agree that this is an “interesting” way to do it. Regardless of that, they did the units need the signals from the other box (or fake signals) before they will do useful stuff.

Hi, Regarding the Lucent box- I wanted to let everyone know that once it locked to satellites, I have a 10 MHz out. The output was a square wave with some ringing, but I built a three element low pass filter and now I have a really nice 10 MHz sine wave. Thanks to all! Last question.... I see it has a RS-422 output on one of the connectors. If I build or buy a 422 to 232 converter can I expect to be able to view the unit's data output with something like Lady Heather or Tboltmon? Or at least see an output with Hyperterminal? Thank you.

Hi These days, a RS-422 to USB adapter is a sub $20 item, even from a “name brand” outfit with real drivers. . If you shop a bit, you can get some dirt cheap USB to 422 adapters at the risk of having issues with the drivers (now or down the road).

As to what you would see, find the manual for the Motorola receiver for details. I don't have the link, but somebody else does. You get some info about the device and info about each satellite. You can use a 422 to USB converter or clip on either wire with a digital scope that decodes simple serial streams, like PicoScope.

Hi, The USB to RS422 adapter arrived. According to the online manual for the adapter, the RS422 signals I'm looking for are: Send A+ Send B- Receive A+ Receive B- Is there a pinout posted somewhere for the Lucent box RS422 D sub 9 connector? Thank you.
