Mitutoyo Dro

Hello looking for some help from the electronics people I have got a Mitutoyo GM type dro counter that has the round 6 pin connectors that take the AT2N type scales which work fine but I bought 2 AT112 later type scales with 15 pin D type connectors and wonder if they are compatable by changing the sockets on the back of the readout to 15 pin D type I know you can get round to 15 pin D connector adaptors from Mitutoyo but they want about =A390.00 each for them and I could buy a new DRO from Singapore for not much more than that so hoping that someone might have some of the answers or other ideas ( such as a cheap 2 axis readout with the correct connectors .) Thanks Colin
