Connecting to a OHP easily

Hi, we have just bought an OHP but I can't figure a way of easily changing the connections to it without having to get a ladder and connect something to it and have wires trailing from the ceiling. Is there a way of connecting a terminal , connected with wires or wirelessly to the OHP, so that we can just put the connections into that without having to change the connections to the OHP?

If this helps I've listed what connections there are on the OHP:

S-Video, Video (Yellow one), Audio L and R, RGB IN, RGB OUT and RS232.

just get extension cables for them and run them to somewhere easily accesible
