Log Operation
When doing QC work with films or tapes, an operator must look for flaws, and log
the type of flaw and time code, often by hand.
The SloMoPro includes a mode to help automate this task. When in this mode
(accessed thru the Menu Item "Log Operation",) Machine #4's output is used to
send a special command upon the operator's pushing of one of the buttons
immediately below the display. This command will be in the form:
Where:
1. bb
is button # from 0 to 5. This is intended to be an indication of the type of
flaw found by the operator and is entirely definable by the user.
ff mm ss hh
preceding the button press. It is in BCD format.
cs
is checksum of all the bytes in the packet preceding it. The checksum is
truncated to the least significant 8 bits.
The data transmission from the SloMoPro follows the standard P2 specification.
EIA RS-422A at 38400 bits/sec, 8 data bits, 1 stop bit and odd parity. The user will
need to (usually) provide a RS-422 to RS-232 or USB converter, and will need to
provide a simple application that receives this data and presents it in a useful
format. JLCooper may provide this software at some point in the future, depending
on demand. Contact the factory for details.
For details on how to connect your SloMoPro to a computer, refer to the pinout
section.
