On my Win XP Computer, I installed V5.0 DCS and upgraded 4 TIU (Rev I, I3B and L) and 4 Remotes. The upgrades worked fine, the TIUs and Remotes all respond as V5.00. TIUs are not connected to any track or engines. The TIU are powered through Fixed Port 1. The TIU was connected via COM7 with a USB-Serial adapter.
Upgrading the TIUs and Remotes requires me to connect a 4 pin handset cord and an audio cable. I connected and disconnect those cables as instructed.
Then I tried "Transfer Remote Data to PC" (for cloning) using the Rev L TIU. This instructs me to connect a 4 pin handset cord which I do. When I start the procedure, the DCS Loader program just keeps on searching for a TIU via COM3 and COM7 (its on COM7 through a USB-Serial adapter).
The DCS loader is set to scan (Auto Search) for the COM port which it does, but even though it scans COM7, the loader can't find the TIU there. Rebooted several times. Powered on/off several times.
The procedure instructs me to hold down the thumbwheel which I do.
I can't figure out what I am doing wrong.
