[time-nuts] Motorola GPS + 5 MHz oscillator ?

[Bill Janssen]

I have a friend who has  two of the surplus (telephone Co. ?) timing 
receivers. That use a Motorola
(A111219115) GPS receiver and a ovenized 5 MHz oscillator

It has external connectors for 5 MHz., 1 PPS, -48Volts, RS232, and the 
Antenna.
He has the matching Antenna which is marked 5 Volt and looks like it has 
a helix inside.

What I want to do is get one of them running so I need to find the 
correct commands to set the
Lat and Long. and read the status messages.

Anyone recognize this equipment?
