Hardwiring Xenarc 700TSV

Inuyasha · 06-10-2004, 11:04 AM

I recently bought a used 700TSV but it did not come with car adaptor. Can I buy a replacement at Radio Shack, and if so which one do I get? What do I look for?

I was thinking of hardwiring it if possible but do not know how to go about it. I did a

it appears some people have burned their screens out using the car adaptor because they reversed the polarity. From what I read some people took the wire with the lettering as the positive...

If anyone could help me out it would be great. I am new to this so please bear with me.

Thanks.

My Xenarc 700TSV has been hardwired with no problems for well over a year. The input rating is fine for fluctuating automotive use. I'm sure it isn't wise to reverse the polarity (never done it), and I don't recal off-hand which wire is which. If you have the wall AC adapter, you can easily figure it out with a multimeter. Most power connectors are center-positive (i.e. the middle pin is +) and I think this is the case for the Xenarc, but better check it to be sure!

The car 'adaptor' must be a big waste of money, as all it will be is a cigarette lighter plug and some wire. Unless you want to easily unplug your screen, hardwiring is fine (you can use any plug for that matter, wired in to the car's power).

So you are saying directly wire it to the car with just straight wires being center is positive? This setup is also ok for the screen to be on while cranking?

I did a search on hardwire xenarc and power xenarc but I don't get much results. Could anyone point me in the right direction? Egar to get this up and working. Thanks. I guess I could always go the invertor route but I read that is inefficient cause it goes dc-ac-dc again.

i haven't try this yet...cuz i am not done with my dash mold....but i will try to hardwire lcd by the pc molex yellow wire ....if u search more i believe someone here already try it....and it worked....hope this help...

Nearest I can tell there is nothing special about the Xenarc cigarette adapter. It has a 1A/250V fuse. If you look at the back of your Xenarc you'll see that the + line is the center one.

My best advice: take your monitor to RadioShack and find a cigarette adapter that fits the connection to the monitor (it's a standard connection, but I don't know which one). Double check the fuse. Double check that when it's plugged in you get -12v from the outside of the monitor connector to the inside.

Ok, looking at the Xenarc ac wire with the plug cut off....

Inside the outer black cover, I have a bare wire and then a wire with white plastic cover surrounded by the bare wire.. So, im asuming the the white covered wire ( center ) in the possitive and the bare wire is the ground.

Right?

The center connector is positive and the outer connector is ground. mine has been hard wired like this for a couple of months now with no problem at all. Find a plug that fits somewhere, an old AC adaptor or some such, cut it off and wire it in. It is definitely the best way to go. Just check that polarity at least 3 times before you power up for the first time!

Are you talking about any cig lighter plug with a fuse in it?

Sorry I should have been more clear in that response. I meant any plug that fits the Xenarc DC in application. Preferably hardwiring would take place behind the dash so that the cigarrete plug would not have to be used. Although I do strongly recommend fusing any type of hardwired installation!

EDIT: What year is your CBR 900? I personally Ride an '02 R1 and have been riding for over 10 years now.

Shouldnt it the 12v be regulated going to the screen? Im going to put a dc converter to regulate the 12v to 18v for my carputer tx3, should i do the same for the screen?

Well i have the Xenarc ac in, just not the other end. It was cut off. So all i have is the Xenarc ac adapter with the plug that goes in the wall cut off. I was thinking about getting an old cig adapter and splice it in. I also need to know how big of an inline fuse i should use.

my RR is a 93 red white blue with a 97 front and tail conversion. I dont ride it, its my show bike. My ducati 916, is the bike a ride all the time.

According to the instruction manual included with my monitor it will support a maximum input voltage of 24 VDC. This leads me to believe there is a regulator on board already. Therefore mine is fed directly from my cars power and so far has worked flawlessly.

However on my PC I did choose to regulate the voltage but my regulator could not support both the monitor and PC. If I had a more substantial regulator I would probably have chosen to regulate them both.

On a side note my PC said it required 12 VDC in but funtioned poorly with the output voltage on my regulator set to 12. Bumping output up to 13 VDC has made my system bulletproof and rock solid.

Doesn't it have to be regulated? +12Vs from the ACC of the car will be good? I am not too sure about regulation and all. Thought I had read that some people will fry their LCD.

Nope it doesn't have to be regulated - look on Xenarc's website http://www.xenarc.com/product/700ts.html, under Specifications it says "Operating Voltage Range: DC 11V ~ 24V, 1A". So if it's under 11V it just won't work (no problem, the voltage should never be that low anyway except when cranking), and if the voltage hits 24V, then you will need to replace a lot more then just the LCD (just about everything in your car that has power going to it). Car power flucuates from 9V-15V, but should never be under 12-13 except when cranking. Usually its about 14.5V. I'll tell you, the more I read about this screen, the more i love it!

This isn't a lilliput where talking about here

seriously though, I have heard of lilliputs getting fried from unregulated voltage, but Xenarcs will be fine.

Thanks, SpeedFreak03

Yeah I had read alot and it appeared that the lilliputs got fried but i swore I saw one or two xenarcs in there as well. I could be wrong. Can anyone else confirm?

Thanks
