Yakumo AlphaX Pinout - Help

[TOLiS_GR]

Hello guys, I've been searching to make a serial interface for my yakumo alpha x and I can't find anything..

As far as I made it, I found the connections of the pda's connector on a chip MA3243E (maybe it's a MAX3243E?)

any ideas?

is there any software I can for example start sending data to a serial port and check with a multimeter if there's voltage there?
