Okay I'm confused by this one...

I got a programmer about six months ago when I started using some of the Hitec digital servos. I works flawlessly on the 5985's and the 5955 I've used it on.

The problem is that I got two new 5625's for the throttle/choke on a new gasser and those have been giving me fits trying to get them programmed.

Both servos exhibit similar behaviour although not exactly the same. When trying to perform a reset, I'll get several "fail"s and if I keep hitting the button, they eventually reset. Then when setting the neutrals and end points, one servo dutifully displays the appropriate numbers and takes the settings, but when I exit out of that menu, the thing won't work on the manual test. If I try to get into that function again, it will drive the servo past the 60 degree sweep on one end and lock there until I shut off the programmer. If I reset it and try again it will usually work. Tried playing with it quite a bit last night and it seems to be working right now.

The other servo flashes four digit numbers interspersed with the correct number range when trying to set the neutral and travel limits, but once set with the appropriate numbers, it seems to work. If I try to reset that servo, sometimes it will work on the first try, other times it will take three or four attempts after displaying a "fail" screen.

After a substantial amount of messing around with them last night, I've got them working where I want them but it makes me wonder if there is something I'm missing here or if it's just a quirk with that model servo?

I've not used a lot of Hitec servos, but these two 5625's are the first of that particular model and were purchased new less than a month ago. I find it really hard to believe that I've got two bad servos right out of the box.

Got any ideas?

It's hard to say... you're not programming through extentions are you? If so, this might be the problem.

Thanks for getting back to me Mike.

Nope, no extensions. I've tried wiggling the plugs a bit, checked for any obvious damage and I can't find anything visibly wrong with either servo.

Beats the tar out of me what's going on but it would seem to suggest some sort of connection problem, or a problem with the boards in the servos. I just can't see two of them doing almost exactly the same thing and as I said, the programmer works just as advertised on the other servos I've tried it with.

I doubt if it's a connection issue. How old is the programmer and does it have the latest software? What is the date code on the programmer? (Small round sticker)

Mike.

I bought the programmer 12-29-2006. Date code on the little green sticker is; 06.10 It has the latest progamming as far as I know, no version number is displayed on startup.

I went and bought another new 5625 and it's doing much the same thing, but a combination of what the other two are doing. Program reset went just fine, tried to do a center/endpoint adjust and it failed 4 times before finally going to that screen and now it's displaying "-8211" in the window. The difference in this one is that it doesn't flash to the appropriate numbers which IIRC is 0-225? As you rotate the dial it goes from 8407 to 7900 something.

Sounds like the programmer?

edit info:

I called tech support and talked with one of the guys about this and I'll be sending the programmer in for a look see.

Thanks Mike!

It sounds like the programmer... I would send it in and let us check it out.
