Communications are working great on the Okuma. Gar's Isolator is allowing 19,200Kbps speeds, the max speed of the machine.
It's funny when I was having problems the first thing the tech from Okuma said was the speed is too fast. I explained that I was using an optically isolated cable. He changed the speed to 4800 and said I bet this fixes it.

Boy was he wrong
I don't know why they want a different file name. I'd rather it went off the O word to eliminate confusion. It might have something to do with the eithernet/data server option. Which I ended up getting installed on the machine. Okuma doesn't provide DNC operation in the standard machine configuration. It's a $4k option, the eithernet with data server was $6k. It's a no brainer considering the ultra slow 19,200kbps maximum speed, and the data server bumps up the machines small 512k memory with a hard drive that you can run the program off of. I haven't had a chance to figure it out yet though. The tech that installed it has no idea how it works, so I'm waiting for the application engineer to stop by and test out the tech's work
I can set the machine up to receive and then go to the office and send the file. I don't have to walk back and forth a bunch of times. If the file name is the same as a file in the control's memory when I get back to the machine it asks if the file should be overwritten, then continues with receiving the file.
I does seem like they are making a simple thing WAAAY more complicated than it shoud be. And a lot slower too

The bulliten was a little different than my machine was, but it got me closer than anything before.
