Wondering if anyone on here can point me in the correct direction. Yes I know I am talking about 'antiques' at this point, but I am looking for some specifications on the old Javad Odyssey receivers. I have a full set that I use for static, about once a year which you can see at the top of this post: https://support.javad.com/index.php?threads/javad-generations.1248/
The internal batteries are LONG gone, and I have been powering them with a inherited setup of old trimble-type camcorder batteries. Well I was doing some maintenance here and found that all of the batteries are shot I can barely get 75 minutes out of them, and I have a big static job coming up. The old batteries have quadrupled in price and it doesn't make sense to try to source the old lead-acid ones again as I have been looking to go smaller and lighter for some time.
What I would like to do is power the GPS heads with the same batteries as the majority of my powertools, the standard Dewalt 20v. I had been using a 12v setup on the old camcorder batteries, and I was going to try and make a circuit that converted the 20v Dewalts down to 12v, but then I remembered that the GPS heads have a pretty wide range of external power input voltage. I can't find any manual or specs sheets on the old Odysseys though. What I can find is the Alpha & Delta receivers are 7-30/35/40v input, as seems pretty standard for all the Javad stuff.
It would be much simpler for me to just use these tool batteries for external power as-is without modifying them. I think I am OK based on the wide input range history of what I can find, but I would hate to plug in 20v and destroy a head either as I don't have the funds to replace them just yet.
So the question is, does anyone have a copy of a spec sheet or manual for the OLD Javad Odyssey integrated receivers? Anyone with Javad have a link to the secret manual archive not indexed on search engines? Or any of the engineers venture to guess if I will be OK on the input voltage? I would appreciate any guidance.
Also, I put this in the general RTK category as not really sure where to put it. Maybe eventually think to add a section for retired or legacy equipment?
Thanks in advance.
