Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.
So usefull to make my installation a breeze. 5 stars on quality.

FRAME IMAGE OUTPUT WITH STROBE LIGHT
A full frame image with vertical resolution of 485 lines (XC-ST50/ST30) or 575 lines (XC-ST50CE/ST30CE) can be obtained with a strobe light by firing the strobe when the exposure time of the two fields overlap.
� Timing and conditions
<Timing chart by restart/reset>
EXT HD
Continuous signal: 15.734 kHz (XC-ST50/ST30), 15.625 kHz (XC-ST50CE/30CE) Allowable frequency value ±1%
EXT VD
VD: XC-ST50/ST30 (1/60 sec), XC-ST50CE/30CE (1/50 sec) Four or more VD pulses are required.

Exposure time for Odd field Exposure time for Even field
Video output
Odd image Invalid image Even image
Valid frame image
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside. Avoid lighting the scene during the light-emitting inhibit zone defined below. (The field is transfered to the storage area of the CCD, so it can be read out.)
Note
: For best performance, it is recommended not to flash between VD and VD + 10H (XC-ST50/ST30)/ 16H (XC-ST50CE/ST30CE).
