The most popular tire monitoring sensor system in the RV industry is fully compatible with SilverLeaf VMS monitors, including VMSpc. PressurePro sensors install directly on the valve stem, making it easy to install. The receiver can be mounted anywhere in the RV, and requires hooking up just four wires.

If you already have PressurePro sensors, all you need is the Receiver ($295.00), power cable ($20.00), and antenna. Two antenna choices are available. Smaller coaches with centrally located receivers can use the 6" antenna ($15.00). Larger coaches usually require the 35' cabled antenna ($50.00), which allows more flexibility in the location. The system can work side-by-side with the PressurePro display, if desired.

If you do not already have PressurePro sensors, they are available from SilverLeaf Electronics for $50.00 apiece. Some coaches may require a Echo Signal Repeater ($93.00, incl. cable), especially for long trailers and tows.

More information on the PressurePro systems are available at www.advantagepressurepro.com.

You may need to update your VMS software to use PressurePro. Call us for details. For VMSpc users, version 2.4 (or later) is required, and is available for free download on this web site.

VMS 440 CL

Quite simply, the most amazing VMS yet. Get the full suite of gauges and features in brilliant color - and a lot more besides. The VMS 440 CL also is a digital video monitor, and it can combine video and VMS information in extraordinarily useful ways.

VMS 440 for  web.jpg

Like all the VMS products, the VMS 440 CL displays all your temperatures and pressures, performance information, trip information, and diagnostics. But it uses a gorgeous full-color display - the brightest of its kind - to enhance its utility.

But that is just the beginning. The VMS 440 CL also contains a powerful digital video processor that allows it to take any type of video input - from a GPS or camera, for example - and size it, scale it, and place it anywhere on the screen. It can instantly switch from a full-screen view to a windowed view - and it can display VMS data at the same time.

The VMS 440 CL can accept up to four video inputs, and switch between them either automatically or at a touch of a button. Each input is separately adjusted for perfect hue and contrast. This opens up a whole new world of options for your dash.

Problem: You want a VMS, but you wanted mounted in the dash and there is no room.
Solution: If you have a conventional video monitor, replace it with the VMS 440 CL. The VMS 440 CL is compatible with almost all cameras, and you can still watch your tow car while watching your VMS gauges.

Problem: You want to be able to watch your GPS, tow car, and VMS at the same time.
Solution: Use the VMS 440 to monitor either the GPS or the rear camera. This is particularly effective with the rear camera - a small window in the VMS 440 CL is ample to show the tow car and the cars in the adjacent lanes.

Problem: You want two cameras in one monitor.
Solution: The VMS 440 can be programmed to automatically switch from one camera to the other every few seconds, or a touch of a button switches the image. It can also automatically go to the full screen mode when the coach is put in reverse - perfect for your rear camera. And each camera signal is independently adjusted for brightness, saturation, and hue, so the image always looks great.

Like all VMS displays, the VMS 440 CL provides all the accurate readings from the engine and transmission, including the plain-language diagnostics, performance gauges, trip information, maintenance tracking, and more. It supports all our accessories, and is just as easy to install.

New Product Announcement!


VMS 330 Image Goes Here

Have you always wanted a SilverLeaf Electronics VMS system for your coach only to find that you don't have enough room in your dash for one?

The VMS 330 takes advantage of the back up monitor already installed on most motorcoaches on the road today by overlaying your vehicle's digital instrumentation and diagnostics on any color LCD back up monitor. The display is selectable by showing just camera, just data, or both at the same time.

Along with all the digitally accurate information from your engine and transmission, it comes with built-in support for Pressure Pro™ tire monitoring. **Additional Equipment Required**

The VMS 330 hides away unseen inside the dash inline with the back up camera and is operated with a small control pad that mounts within easy reach. Installation is a snap!

Newest Tier 1 Facility

We are pleased to announce the addition Master Tech RV in Elkhart, Indiana to our list of Tier 1 service facilities that are certified for service, repair, and custom aftermarket installation of SilverLeaf products.

Running VMSpc on a Surface Pro

The folks at Motorhead Garage did a segment on our VMSpc product recently - you may have seen it on the Velocity Network. For that video we installed VMSpc on a Surface Pro. I thought the results were excellent, and I ended up making the Surface my personal machine.

Installation was easy using the newly Signed Drivers.

I found a lot to like with the Surface Pro. The screen was sharp and bright - especially if you keep it plugged in so it doesn't try to save power. The form factor is different than the other pads - it's taller or longer, depending on how you look at it. I made some custom screens, but I found that it was easier to do this using the touchpad than by trying to use the touchscreen, even with the stylus. There is also a little glitch in Win8 where if you turn the unit so the screen switches portrait/landscape mode, and then back again, it doesn't restore the window to the full screen size. But I expect that Microsoft will fix that glitch.

Overall, I really like the Surface Pro. I own an iPad and two different Android pads, and the Surface is easily superior to them all. The only advantage the iPad has is battery life, but the Surface is faster and runs all the software I need to run. I also prefer the Surface form factor. What really surprises me - I generally dislike Microsoft products and I heard a lot of Win8-bashing before I bought this machine - is that I find it easier to use than the iPad.

I still make a lot of use of my Netbook - mainly because it has the best keyboard. I also use an Android pad a bit, since it has by far the best battery life. I occasionally bring along my full-sized laptop, but only if I know I am going to need it for some serious work. But the Surface Pro is now my main road machine, and I have hardly touched the iPad in a month.

Now that we have new wireless VMSpc adapters, I'm looking forward to testing the Surface Pro with the improved Wifi interface. Unfortunately, my personal coach is too old for J1939, and we won't have wireless adapters for it. Our programmers are also hard at work on the iPhone and Android interfaces for the little VMS unit. Keep watching here as we release the new versions, or give us a call and we'll put you on a list to be notified when your particular combination is complete.

Connect It with Bluetooth or Wifi

Total Control from Your Phone or Tablet!

Put your control panel in your pocket! If you have a SilverLeaf RV-C coach system you can now add our TM-540 Bluetooth Module and connect your Android phone or tablet. You now have a wireless connection to your coach that you can use on the sofa, from the driver seat, or even take outside. You can both monitor and control - so you can start your generator or turn off your water pump from anywhere within range.

We use a high-power Bluetooth transmitter to reach distances of over a hundred feet. Installation is easy - Plug into the diagnostics port or tap into the existing Silverleaf connectors or connect 4 wires. Download the software to the phone or tablet, and then pair the device.

The TM-540 Bluetooth Module is $295.00. It works with Android phones or tablet with Bluetooth and Android Versions 2.x. Android 4.x are not supported.

Truckers Welcome!

This company was founded by RVers, and we design all our products with RVs in the forefront of our thinking. Sometimes we forget that other folks might be interested in getting a little better fuel economy.

This was pointed out to me rather forcefully this morning when we got a call from a trucker who ordered a VMS. He will be far from the first professional driver to use our products. Kenworth and Peterbilt have been using our products for years as both a driver tool and a data analyzer in their in-house test fleets. Allison has a batch of VMS units as well. But most gratifying to me are the professional truckers that have discovered our products.

One fellow stands out in particular. He is a route driver, running basically the same 300 mile loop every day in North Carolina. That makes him the perfect test to see if all this stuff we say is true - whether you really can save fuel and get better performance with a VMS. You might think that an experienced professional wouldn't need an electronic device - it should already be instinctive.

He says it took him less than a week to discover otherwise. By watching carefully and experimenting - and even taking notes so he could compare his results on the same hills each day - he was able to adjust his driving with amazing results. He went from getting 5.0 mpg to 5.5 mpg - a 10% increase. At current prices that's almost a twenty dollar bill extra he gets to put in his pocket every day.

So if you are a trucker - Welcome to SilverLeaf! We're glad you found us.


Introducing the Video Rats Nest Eliminator!

It's a bit of a departure for SilverLeaf, but there is a good reason for it. We were looking under the dash of a coach not too long ago and saw a most amazing rat's nest of cables. A whole family of nutria could have been living in there, and I had to ask the tech I was working with what they all were for. "Video", he said. "We have side cameras, and we run them to the dash, the overhead TVs, and so on. So we have a switch box, a few relays and diodes, some splitters and amplifiers. It's all in there."

"All those pieces and parts - there has got to be a switchbox out there that could do that in one box.", I prodded.

"If you can find one, let me know. We'd buy a load of them." He didn't sound too optimistic.

And indeed, there isn't such a thing. Sure, there are a lot of video switches that are designed for specific needs - but nothing that was designed for an RVer that wants to be able to check his side and rear cameras on more than just the dash monitor. I looked everywhere and couldn't find one.

So we just had to make one ourselves.

And now, three months later, we have the VDX 404 Video Switch. It takes four video sources and routes them to four video outputs in pretty much any combination. It responds to up to a dozen inputs, such as blinkers, transmission status signals, and accessory switches, and routes the video signals automatically in response.

Adding more monitors and cameras is trivial, up to the number four. Every output is buffered, eliminating the need for amplifiers or isolators. Every output is true to its source. And installation is as simple as it could possibly be.

One great idea we had was matching it with the new Garmin GPS. You can plan your trips with the GPS on the big-screen front TV, and then when you start driving watch the GPS on the VMS video. You can even add a video monitor on the passenger side - let the "navigator" plot the course, while the driver sees exactly the same GPS maps in the dash.

And that's just the beginning to the ideas that this device makes practical. Expect to see this in new coaches this Spring from several manufacturers, and in aftermarket installations across the country.

Here's a Great Example of One Man's VMSpc

Here's an excellent example of how one man, Scott Hicks, has set up VMSpc to work alongside DeLorme on a 2003 Tradewinds. Click here for the details.
Scott's using a Jotto Desk to hold the laptop in place. He has the details laid out - along with better pictures - on his personal site (www.scotthicks.com).

Please direct any technical or sales questions to SilverLeaf Electronics, and not Mr. Hicks. You may post your questions on our VMSpc Forum or e-mail us here.
