Dan I would look at the 2.5mm jack and try to follow the leads back to see what chip it is that drives that jack. Chances are that the 2.5mm jack IS rs232. Since you only need 3 or 4 wires for a serial connection (they ussally use a DB9 but they just don't use all the connection. Anyway I went and found the Service Manual for the Tascam 322 model: http://dsprototyping.com/Tascam_322_service_manual.pdf
I think thats the sister model to your model. Good Luck! Andrew Buczko \¥/ Howdy all, \¥/ \¥/ I have a pro Tascam cassette deck that has a remote control interface. I \¥/ want to reverse-engineer it and build a pathway to control it. While \¥/ preparing for my new project tonight, I was looking through some \¥/ technical documentation and discovered through my manual that my deck \¥/ has a sister model with a serial interface: \¥/ \¥/ http://tascam.com/content/downloads/products/328/302mkII_TECHDOC.pdf \¥/ \¥/ Naturally, this leads me to think that the interface is probably on the \¥/ circuit boards somewhere and just deactivated, as manufacturers often do \¥/ to save money. I took some photos and put them here: \¥/ \¥/ http://imgur.com/a/cAg9t \¥/ \¥/ Does anyone know of any visual cues I could use when looking for this \¥/ interface? Serial often uses a DB9 connector, so this would probably \¥/ mean I'm looking for a PCB with a disconnected 9-wire connector, \¥/ correct? \¥/ \¥/ If this fails, I will fall to my backup plan of just using the 2.5MM \¥/ remote jack, but using a null-modem cable over serial would probably be \¥/ ideal for prototyping purposes, I would think. \¥/ \¥/ Dan \¥/ \¥/ -- \¥/ Dan Swick \¥/ [email protected] \¥/ _______________________________________________ \¥/ Discuss mailing list \¥/ [email protected] \¥/ http://synhak.org/mailman/listinfo/discuss \¥/ Dungeon Studios Prototyping www.dsprototyping.com [email protected] (330)814-6103 _______________________________________________ Discuss mailing list [email protected] http://synhak.org/mailman/listinfo/discuss
