I also purchased two of these units.

Although I could not find a spec. It appears that it has the same Pinout as the:

ONCORE Remote GPS Antenna Receiver
ACUTIME 2000
Trimble Palisade


The Provided cable only brings out pins 1-5, 9, 11, 12
These Correspond to

Pin 01    Red Vcc (+8 - 36 VDC)
Pin 02    Purple Port B Recv-
Pin 03    Orange Port B Recv+
Pin 04    Gray Port B Transmit-
Pin 05    White Port B Transmit+
Pin 09    Black Ground
Pin 11    Green 1PPS Transmit+
Pin 12    Blue 1PPS Transmit-


I connected +12VDC to Pin 1 and Goind to Pin 9 and after about 20 Minutes I got good 1PPS from Pin 11 with 50% Duty Cycle (500ms).

I have not connected the RS422 Yet but on the scope it looked like it was transmiting something.

I do not know if the protocol is:
NMEA
ONCORE Binary
Trimble TSIP
Trimble TIAP

or some other Protocol.

As I learn more I will let you know.

I have PDF's for both the ACUTIME 2000 and the ONCORE Remote which I can send to you.
There is information on www.leapsecond.com about the Trimble Palisade.

Hello Time Nuts,
Would anyone have a PDF manual and/or the configuration software or
 links to it for a Symmetricon 58534A GPS Timing Antenna they would be
 willing to share ?

Many Thanks,
Phil Harwood
