MR-J2 software and cable

I need to do some adjustments on a MR-J2 drive for a rotary table. I found the link to the software here on CNCZone (thank you). I just need the cable that connects the drive to my PC. Does anyone have the specs for this. Mitsubishi wants $86 for what they refer to as an RS-232 cable. I've made several cables and because I am cheap, can't see spending $86 on $4 worth of parts. Thanks for any help.

You don't necessarily need to connect to the MR-J2 to make any adjustments. If this is a Mazak, the software is loaded on the control already. Just open the application through windows...

It may be an MPLUS control which doesn't have onboard s/w.

Yep... M Plus doesn't have use a Windows OS...
... it also doesn't use a MR-J2....

The cable to connect to a MR-J2 is a DB9 to MDR (20 pin I think)... but AFAIK, MR-J2 didn't start usage until Fusion. So the set up software is loaded on the control....

Sorry to say that this, but this machine has 2 MR-J2 drives in it, 1 for the rotary table and 1 for the ATC. It has an M Plus control, so they must have come before the Fusion.

Yes the M-Plus controls used an MR-J2 drive. What is the exact model of the MR-J2 drive? Does it have a CT at the the end or an A at the end. This will matter when it comes to the software and cable that is used on the drive.

Good to know. I figure there was a transition period in there somewhere depending the models... just hadn't seen it. I have seen Fusion machines that ran the old drives and/or relays. Almost like a Fusion control that got stuffed onto a M Plus machine. Talk about strange to work on.

Yes, very strange to work on.

Onthebumper, it has a CT at the end, MR-J2-40CT and 60CT. One for the table and one for the ATC. What difference could there be?

The CT drives are made specifically for Mitsubishi CNC controls and the A drives are a general purpose servo for industrial applications. Both are similar but different
These two manuals should explain most of your questions.
