I followed the link to order the TVS - I received and they don't look the same, looks a tad bigger. Also when checking with my meter I didn't get any readings on the new ones? I installed anyway due to desperation and the TIU seems to work, the transformer powers up and I can increase the voltage as before. Still can't see any locos, add or do anything. I can only run one loco by hitting the reverse button and cycling the power. On the second track I can't even start up a loco. Both tracks are fixed voltage tracks and fixed out but it says out of range briefly and then finds nothing to add.
So I decided to upgrade the software to version 6, the TIU upgrade went smoothly but I can't get it to upgrade the handheld. I have a serial adapter and a USB cable - with serial adapter I get a message saying my computer doesn't have a serial port (even using the adapter cable) and with the direct printer USB connection it search's for TIU on Com 5 I get a message saying TIU is having a hard time finding USB connection and to cycle power - which I have tried a number of times. I've done a software upgrade before but no luck this time.
