RS232 wiring
The following diagram (rear view of unit) shows the pinout of the 5-pin mini-DIN
connector. To create a null-modem cable (i.e. to link a PC direct to the unit), create a
cable with connections as detailed in the table.

handshaking
Subcarrier lock & sync pulses
Subcarrier locked to line frequency in PC Out mode.
Sync pulse widths conform to video standards.
Genlock Overlay circuit
Will lock to either a standard stable composite or S-video signal (1v p-p).
Internal sync circuit will remove some sync noise and head-switch glitches.
Independently locks to sync & subcarrier.
Subcarrier lock range +/- 200Hz NTSC, +/- 250Hz PAL approximately .
Fine subcarrier phase adjustment over +/- 12 degree range.
Power requirements - external version
Consumes approx. 350mA @ 12v.
Voltage requirements: minimum smoothed 12 volts DC, maximum 16v DC.
Requires 'center-pin positive' 2.1mm DC power plug input.
Reverse polarity protected.
