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 ES-SloMoJ 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:
74h bb ff mm ss hh cs
Where:
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 is the timecode as returned from the machine
immediately 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 ES-SloMoJ 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.
