VMSpc and Pressure Pro issues. I have been using VMSpc since March 2011, and am happy with it. Recently I had an opportunity to purchase a TPMS that consisted of 12 sensors (2 spares), a Pressure Pro J2497 to J1708 Bridge, a repeater and harness to connect to the VMSpc JIB. After installing the sensors, I was able to "Learn" all of the sensors for the motorhome and toad, using the VMSpc "Tire Status" Menu. The sensors and the repeater send signals to my VMSpc and are displayed on a separate monitor. I use the laptop screen for the DeLorme mapping data. On engine start, usually only one or two sensors report, and after 45 minutes or so travel all of the motorhome sensors and two of the car sensors are reporting. During a 6-hour trip, the motorhome sensors may continue to display, but several times, the display for the inside duals will quit only to reappear. Sometimes all 4 of the car sensors report, sometimes not. I have attempted to reassign those sensors, but have not had much success. My feeling is that I want to know the tire pressures BEFORE I start travel - not an hour or so down the road. (Before purchase of the Pressure Pro system, I used a "stick" type tire gage before each trip to check pressure - I felt that the TPMS would eliminate this step, and continually monitor pressure while driving, but now the indications come and go during travel.) I know not to expect all sensors to report immediately, but shouldn't they report within 5-10 minutes? After talking with the Pressure Pro technical rep and the local rep, I sent the sensors and the repeater for test - after testing, Pressure Pro reported that one sensor was bad, but the other sensors were operational. It was suggested that I use an external antenna, and it is now installed. Now, three of the toad sensors report "No sensor assigned" - when "Learn" is selected a status box appears reporting "Listening for Sensor #6" however, after 10 minutes, nothing changes. I observed the box immediately below the "Abort Learning" reports OK and then Error - this repeats. I have moved the antenna to many different locations with the same result. Would appreciate any info you could provide before I declare this as junk and throw in the trash.
Hello Red T Call us at any time during your troubleshooting. Its during your dialing-in period we can help. Not much we can do if you've canned the system BEFORE calling in the big guns. Your write-up is interesting AND is printed up--will be brought to the folks who know the system pretty well. Give us a phone number where we can call you to blaze a path forward. Or, at you convenience, give us a call. The forum is great for sorting out details and the experience of other users--but not a place for show-stoppers. Call us so we can set you up properly.

Update - I temporarily removed the right front motorhome sensor and one at a time, reidentified each of the 4 toad sensors as #1 - noted that when I removed each sensor, the VMSpc display illuminated RED indicating loss of pressure. This verified that the sensor was functioning properly. (One sensor was found to be bad.) I then reinstalled the motorhome right front sensor, and installed the 4 toad sensors, "learning" each one as it was installed. At the end of this procedure, all 6 of the motorhome sensors and the 4 toad sensors were reporting. At this point, I permanently installed the external antenna. I can be contacted after Nov 4th at this number: 623-878-6859. Thank you for your response.
Hello Red If I follow your lines of troubleshooting, you have at this point sorted out the drop-outs. It appears placement of the antenna was important and that by finding the 'sweet spot' you were able to find all your sensors. Is there something I'm missing or is this resolved? Art
For the moment (with RV parked) all appears to be operating normal. The real test will be during the next extended trip. Thank you for the assistance.
