The units comes with no H/L jumpers. Will it operate that way? If not how many jumpers are required and do you need both H & L jumpers?

I do not know what you mean by H/L jumpers. I didn't have any problems setting up the device. It works well for my purposes.

I tried every which way to make this product work and nothing did. It didn't even work to try to get my money back for a faulty product.

I did not try it without jumpers. I made up a code and I had every terminal going to either H or L. it worked for me.

Sorry, I don't recall what "H/L jumper" refers to. The product comes complete, except for a 12vdc power supply to energize the receiver circuit and its built in relays. The remote came with a battery if I remember correctly. There are terminals, to connect the circuit you want to control, with the relays. It worked for me.

I don't believe there was that option. We tried two of these, but had issues with both. We have since moved to a newer Safety 1st model and love it

This one looks like the one I used. For each position you can use one side positive & the other side negative, it does not come with a jumper. Hope this helps.

It does not have a high and low setting on the controls, mine doesn't cycle that much and it seems to go a degree or two beyond what it is set at before it comes on. with that said I seem to recall the manual mentioning a jumper that could be used to change the amount of leeway before it came on and off. But I cannot say for sure.

My dispensers came with tape and spools for 2 different tape sizes. No flying jumpers. I love the dispenser...

Two single units would be needed for your situation . The laser only works for one vehicle. I love it. No more tennis balls hanging from the ceiling etc.

Yes, ours has two parent units. The range is in the specs. We use it in a 2 story house with a basement and have never had an issue.

You can buy two, and depending on how you arrange them, you probably won't need more. But, you can buy one and the house, or two and the transport unit. I have two regulars, a house unit and an tower unit. Unfortunately my life has not been such, that I felt I could take on a couple of hamsters yet. Good luck with your hammies;]

The rail can not be shipped via ups or other. So we offer the head unit as a replacement operator for current Liftmaster motors that use the same chain rail. Also we are able to offer lower pricing then most local shops- so often customers purchase the head unit here and then the rail locally. We do offer the 8500 with no rail needed but your door needs to have torsion springs.

no..it is a carpet prote4ctor and not big enough for a jumper and doesnt have the cushining you might need. cheers

I think the first controller will control the 2nd set, BUT I don't know for sure. I had 2 sets of a 3-unit version and was disappointed to learn that any 1 controller ran all 6 units. Try to contact the Mfgr or supplier for a definitive answer.

Yes, but if I remember correctly you'll need a short jumper wire. No biggie.

If you mean can you add more units past the 4th unit, I don't know. I only have the 4 units that came with it. It is my understanding that it would be possible to add as many units as you wanted, based on how it works though. But I can't honestly say.

I did not receive any jumper. I made my own with wire and terminal connectors.

No it does not include jumpers or any options other than 'direction' IDE to SATA or SATA to IDE. No documentation at all was included in the package. But the connections are pretty straight forward.

I know exactly what you are talking about!!! I used to have one of those...but it required two cars and it took a little while to work This item is similar to the one I used to have. Mine worked. I don't know if there are ones where you don't need another car....there very well may be. Maybe if you google "in car jumper" or something like that, you might find one.

The jumper enables you to isolate the relay control circuit from the coil (The relay has optical isolation when the jumper is removed). If you remove the jumper you'll need to provide power to the coil separately. This is useful if the device that is controlling the relay can't provide enough current (or voltage) to drive the coils.I have a short video of the relay in operation in my review (http://www.amazon.com/gp/review/R2AZD0UTXMKUD1/ref=cm_cr_pr_rvw_ttl?ie=UTF8&ASIN;=B0057OC6D8) - Unfortunately I don't show the jumper in use though.
