Tascam BR20 Accessory port

I would like to make a simple remote for my BR20 using the accessory port. (I did this before with a Akai GX77, raspberry and some relais) now I want to make something similair, but...

What signal does the BR-20 needs to receive in order to use the control functions? (Play, Stop, FFW, REW, Rec)

I have the service manual and the pinout. Is it only making a (short) contact between pin X and GND?

Or does the deck need a kind of high/low signal?

thanks.

On my ATR 60 it works like you said. But REC function is possible only with diode (1N4148, BAV21, 1N4007, ..) between play and rec input pin (I could check the polarity). Maybe this diode is not needed because this is more modern design.
