Visonic Powemax Plus & XM10U

[nofuse]

Do I need a straight rj11 cable or a crossover cable to connect these together?

I spoke to visonic and they said if I look at the cables next to each other the would look the same but didn't know if this was a straight or crossover config.

I pretty sure its a straight cable ie 2 to 2, 3 to 3 etc. and I think it only uses pins 2,3,4 and 5.
