Seelevel & VMS 240 CL

I installed my SeeLevel 709-A RVC and connected the twisted wires that Siverleaf sent to my VMS 240 CL. I went into the hidden menu of the VMS and selected yes for the fresh water, grey tank, black tank and LP. However, when I go the the diagnostics page all the quantities read 0 even most of the tanks are not empty. What am I missing? I would appreciate any guidance you can give me. Thanks.



Hello Misty

There are two sections where this could be enabled from; one is correct one--the other not so much.

The two sections are the J1708 and the RV-c. You most likely added these in the RV-c. Try using the J1708 side instead. After speaking with Mark (uber-nerd) he's leaning this direction.

Give us a call if some clarification or additional help is needed.

Thank you

DDEC II/8v92

Not new here but was advised several years ago that VMS products were not fully functional with the DDEC II in my 94 Wanderlodge.

Now I'm hearing some owners are installing VMS products, interfacing with their rearview monitors for their 90's models Wanderlodges with the Detroit 8v92 DDEC II engines.

I would be interested in such a system, please advise:

1. Is such a system available.
2. How much does it cost.
3. How does a technically challenged person get one installed.


DDEC II...Will it work?

Hello Da141

The early computer (program) within your DD will either produce the codes or, they won't. Not to sound ambiguous--the final PROM upgrade for DDEC II is v154. Prior versions i.e. 141 were almost as good, and anything prior to that may not produce odometer readings. Version-154 is needed for full functionality. A replacement PROM (for that updated program) can be had pretty easily.

Here is that prom as a bolt-on module:

~$55 delivered.

With that you can connect your new Silverleaf unit using a complete setup which we supply. The basic VMSpc with cables and software are $395 plus postage. A fella or gal who can replace a tail lamp or change the oil in a car can usually install one of these without more than a coffee or smoke break.

That basic unit uses a USB connection to your Windows Laptop or Windows Tablet. All Windows Operating Systems (OS) are supported. WiFi and Bluetooth (wireless) connections are supported for Windows systems prior to Windows-8.

To marry the two (Laptop and VMS unit) a small amount of software is installed. Then shazaam; you're ready to go.
