The top is held on by three screws on the left panel and three on the right panel.
The GMT shown: 21:49:14 is correct.
SVs 25, 26, 30, 23, 13 & 16 are carrier locked but not phase locked.

Some Z12R receivers have DB-9 connectors and some have Fischer Push-Pull connectors.
These are NOT 7 pin Fischer connectors like on the small box Z12.

By recording precision data on the actual orbits of the GPS satellites and using that data along with time stamped data from a precision GPS receiver the data can be reduced to determine the precise location of the GPS antenna used. This is a version of Differential GPS (Wiki).
Enter the co-ordinates into the text boxes to try out the calculations. A variety of formats are accepted, principally:
And you can see it on a map (aren’t those Google guys wonderful!)
This GPS receiver includes an input for an external frequency reference, unlike the Z12 above. This might better lend it to precision GPS work.

Compact Flash drive: SanDisk 90 MB

Remove front panel (+) screws and hinge down the panel.
NOTE: Be very gentle pulling off the connectors after noting which goes where (mine were marked I, II,X and O, but the X socket came off the PCB and needs to be soldered back down.
X: circle light
II: Satellite light
I: Drive light
Remove the three hex head screws using a 3/32" ball end hex wrench.
Remove the back panel (+) screws and slide the PCB and rear panel assembly out the back.
This GPS receiver has the look and feel of the rack mount Z12, but much smaller. If you compare this receiver to the one at the top of the page, it's the same size as the main part and has an identical front panel. But the rear panel uses different connectors than the above receiver and different from the field version Z12 shown in the Z12.pdf manual.

Power In dust cap: Amphenol 97-60-10
Power Cable connector: 3106A10SL-3S
Power Voltage: TBD
To make power cable use: 3106A10SL-3S.
The two power connectors both have pin-B as chassis ground, but pins A and C are not interconnected on them.
This implies that the idea is to have two independent power sources so that one can be changed while the other provides continuous power. For that to work there needs to be diode isolation so the dead battery does not drain the good battery. The ZY-12 supplemental manual has the pin out table.
+10 to 32 VDC
-10 to 32 VDC
Guess input as 9 to 32 VDC.
Z mode: A - receiver reverts to Z mode when A/S is detected, Y - always in Z mode, N - never Z mode.
Ranger mode: 0 - geodetic mode: stores phase data in B-files for post processing, 1- Stores phase data in B-files for post processing in code phase only, 2 - stores smoothed positions in C-files only, used for real time differential corrections (no post processing).
This receiver can be used to receive Y code if it is keyed. The manual describes how to do this with a KYK-13 and unspecified "interface box".
