I am somewhat confused because they say that its an RS232 config but they show a GND for the RX and a GND for the TX which typically is RS485? Thanks for any help. RS-485 would be more like a TX+/TX- and RX+/RX-. There is no real signal ground only a common line more like an earth. They maybe have separate ground lines for both transmission lines, but they are probably still ground referenced meaning the two GND have always the same electrical potential. I wouldn't let myself impress by such strange definitions and just simply try it out, possibly with a breakout box with LEDs to check that the data transmission is really ok.
