[time-nuts] Lucent KS-24361/Z3810A : problem with Z3812A/REF 0 unit power up--RESOLVED!
Hello all, I contacted the eBay seller and he sent me an exchange REF 0 module. I swapped it in and it powered right up. Now there is a single green LED (ON) illuminated on the REF 0 module and a single yellow led (STBY) illuminated on the REF 1 module, so I'm pretty sure that all is well. Thanks to everyone on this list for all of the helpful suggestions. I also want to give the highest praise to the eBay seller, who stood behind his product and very quickly made it right for me!

The cycle of LED’s lighting up during boot is similar on both units. The process on the slave unit (REF0) appears to be controlled by the REF1 unit. Since the signaling between the two is very simple, a lost connection on the cable could cause this sort of thing. LED’s out *after* boot is normal until the GPS locks up to location on the REF1 and then starts sending data to the REF0. Bob Both units are drawing current: the Z3811A/REF 1 draws about 700 mA steady state, and the Z3812A/REF 0 draws only slightly less: 600 mA steady state. So far, I've swapped power connectors between the units and saw no difference, and I tried to power up the Z3812A/REF0 alone, but still no joy. Am I missing something about the setup, or do I have a defective Z3812/REF 0 unit? That's normal. The pair goes ON only when it sees GPS for quite some time. BTW the POWER consumption is fixed. If you have more voltage, the current will drop. regards, Gerhard ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Wiggle the 15 pin interconnect several times if they do not make good contact I think this is what happens.

The interface jumper cable has several short pins that sometimes do not make a good connection. You might check that it is fully plugged in on both ends and that all 15 pins look ok. The cable crosses over the pins such that pin 1 of one end goes to pin 15 of the other and so on. There are some power supply test points on the top of the board that you can get to with the cover removed. There should be +5, +15, and -15 volts in there. Do you have an amplified antenna connected to the GPS Rx input? The antenna should use +5 volts.

Hi Stan, Is there a green LED lit on the board near the power block, or are both red and green very dim or not on at all? I have a unit with the same symptoms as yours. Both output voltages are extremely low from the power block. Unless the green LED is lit or flashing, I'd send it back.

Hi More or less in order of probability : 1) The most likely case is the interconnect cable. A couple of plug / unplug cycles on both ends is well worth the trouble. Also a bit of flexing of the cable may be in order. No it’s not good that the cable is bit flaky, it’s an easy part to replace if it dies later. It’s also a part that goes away once you (if you) rewire the units. 2) Next up is a check of the GPS antenna. If the “No GPS” LED flashes, that’s an antenna fault. Best bet - your REF-0 does have a problem. For entertainment value, you can hook up an RS-422 serial to the Diag port and see what (if anything) the log has to say about the issue.
