Attached is the schematic drawing KIWI Geoff helped me develop for a fast and 
reliable method to use one KIWI unit to stamp multiple recorders. You will need 
a "T" connection off of the PC164C output (or imaging camera) to accomplish this. 
I get them at Radio Shack (Radio Shack part# 42-2536).



Here's the basic steps I use:


1.  When I am within the recording window (i.e. whatever length of minutes of tape I have) 
I hook the VIDEO INPUT of the KIWI to one of the female RCA connectors of the Y on the 
output of the imaging camera and let that sync up while I get the Canon ZR ready. 

2.  I plug the A/V cable for the ZR into the A/V INPUT of the ZR. 

3.  Using the ZR remote control I press the red REC button. (this puts the ZR in RECORD 
PAUSE mode) 

4.  I then hook the yellow video male RCA from the ZR into the other "Y" connector 
from the imaging camera. 

5.  In a few seconds the star field with the KIWI information overlayed should appear on 
the small ZR monitor. 

6.  THEN (and only after I have put the ZR in REC PAUSE mode) I hit the RESET on the KIWI. 
It is important to note here that the A/V of the Canon ZR is both an INPUT and an OUTPUT. 
So if the ZR is not in REC mode the yellow cable of the ZR acts as an output, thus 
sending a video sync signal that screws up the KIWI buffering (I learned this one the 
hard way!). So only record the KIWI data AFTER you have first put the ZR in REC mode 
(REC PAUSE is also OK) and then AFTER hitting the RESET button. 

7.  After recording the Longitude, Latitude, elevation info, Date, and about five or ten 
seconds of UT time, I carefully unplug the KIWI from the "Y" (trying to not accidently 
unplug the camera from the ZR instead, thus disrupting the frame counter). Then I RUN to 
then next station. 

8.  After the event is over I return to the station and record the KIWI info again (making 
sure to hit RESET for accurate data). If the tape has reached it's end I will rewind the 
tape about 1 minute (being careful to not record over the event!) and I record the KIWI 
information again. This allows me to correct the drift in the Datecode (free running 
Date/Time clock internal to the ZR) using the spreadsheet I previousl sent you.
