AV Connector
http://www.PALsite.com  

The Philips VCRs, V2020, V2021, V2022 & V2023 do not have standard BNC/Phone type connectors for A/V input & output. Instead they have a 20-pin A/V connector through which all signals must be connected. Philips provided a breakout box " The 22AV5530" for this purpose. Follow the link for full details.

The circuitary in the 22AV5530 is quite complex and provides switching functions not included in the VCRs. It provides interface not only to audio and composite video input and output signals but serial control data intended for interface to Philips camera units.

If you wish to get External Video in to a V2020/1/2/3 then the signal needs to be amplifed and fed to Pin 17. Similarly Video Output from Pin 18 needs to be buffered before it can drive a 75 ohm line.
