Cord is a Futaba, I've used it with my Flash, no problems. Just tried it with my Optic 6 and my Flash, and the battery read out on the Flash went to around 4 volts (beeping) then it read 24. volts, and no longer transmits. When I first turn it on, just for a split second, it shows correct voltage, then goes to the 24. volts. Not sure, since it all happend so fast, but it may have happened when I turned on the Optic also, I didn't think it made any difference if one transmitter was on or both?

The Futaba trainer chord is not compatible with Hitec computerized TX's....

I guess I didn't explain it right, but the problem is without the cord hooked up. I didn't know if this thing is fried now? Any fuse or diodes to check?

Sounds like you damaged the TX, you only power up the Matser TX when using a trainer chord.

MGLAVIN,
What is the difference in trainer cords from Hitec to Futaba? Specifically the 6 pin round to round that fits Optic and Eclipse. I have the Futaba cord and it appears to work correctly or maybe not.......I took out the student module and plugged in and turned on master. The Master powers up both LCD screens. Controls work correctly. Should both screens be on at same time?
I had a guy I work with flying my Ultimate foamie Bype after just a couple minutes. He only has one eye! He does have a MS-Dos based simm though.

I did not remove the module from my Optic 6, which was the student transmitter (1st mistake) and I think when it made my Flash beep low battery is when I turned the Optic on, then it popped my Flash.... Why are the trainer cords different? It worked ok with my Flash hooked up to a Futaba? If the cords are different, seems you will not be able to use ANY cord and use two different brand transmitters? And if no compatability exists with the cords, WHY make the plugs the same? I know, easy access to parts, no one makes a plug, they just buy it from a company that makes them. I just wonder what it's going to cost to fix my old radio? [&o]

Other RC systems also use the 6 pin DIN connector for Trainer/PC interface systems. Hitec is compatible with Futaba provided that only the Hitec One Way Trainer Cord is used and even then some minor smoke could be emitted from the first edition Futaba 8UAP's trainer board. (easy fix). At no time may the Futaba cord be used between two Hitec TX unless Xtal or module is removed from the "Buddy Box" and at no time may the switch on the "Buddy Box" be turned on as the Futaba cable is "open" at both ends. This information has been well documented on Hitec RCD USA and leading Hitec retailers web pages as well as leading newsgroups for a long time.

Whilst not on the Futaba buddy cable, all leading Futaba simulator interfaces short out pins 4 & 5 (as on Hitec trainer cable) to prevent erroneous RF transmission.

Thanks Alan, that's explained very well.
