The keykode information in sent to the 4025 whenever the keykode reader
successfully reads another barcode. By switching off this serial line, the
4025 will simply count feet & frames, and will ignore any updates from the
keykode reader. At Encore Video, we modified the 4025s by installing a wire
to the output of the RS232 receiver chip. I'm not sure which chip offhand,
but it's on the motherboard, in the back. This line runs to a switch mounted
on the colorists console. Pressing the switch shorts the RS232 data to
ground (crude,... but effective). Handy for those times when prerolling over
a splice would upset the 4025 for the first few feet of the take.
