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. Bob - AE6RV

Hello, I just received my Lucent KS-24361 and set it up on my bench to power it up. I connected the Z3809A interconnect cable between the two units (Z3811A/REF 1, and Z3812A/REF 0) and applied +24VDC to the appropriate pins on the two DE-9 connectors. The Z3811A/REF 1 ran through a sequential test of the four LEDS and then after a few seconds it settled in with the amber "NO GPS" and the red "FAULT" LEDs illuminated. Meanwhile, the Z3812A/REF 0 unit never lit a single LED and is still sitting there with all LEDs dark. 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?
