COM SERIAL PORT PROBLEM--CAN'T UPDATE TO DCS 5.0 OR 6.0

Kevin,

The loader does not see the 6.0 update which shows as an application but did recognize the 5.0 which shows as a DCS file.

The Loader Program will only recognize TIU update files that have a .dcst extender. Make sure that you are using Loader Porgam 5.0.

When I select that file and hit start the loader seems to be working then gives a message that it is having trouble finding the tiu and just sits there.

Typical reasons that the TIU is found when doing a Search from the Loader Program's top menu but not found when actually doing a TIU upgrade, include:

• The 1/8" jumper cable between the ProtoDispatch and ProtoCast ports isn't installed.
• The 1/8" jumper cable between the ProtoDispatch and ProtoCast ports is mono rather than stereo. It must be stereo.
• The 1/8" jumper cable between the ProtoDispatch and ProtoCast ports is installed, however, the TIU was not powered off when the cable was inserted. Note that if the PC is connected to the TIU via the TIU's USB port, that connection is powering the TIU.

The process of doing the TIU upgrade is as follows:

• Remove all power from the TIU, including Fixed Channel #1 Input; the Aux. Power port; the USB port (for a Rev. L TIU only).
• Insert a 1/8" stereo jumper cable between the ProtoDispatch and ProtoCast ports.
• Connect the TIU to the PC.
• Restore power to the TIU. It's red LED should immediately come on steady, without any blinking.
• Start the upgrade process.

Thanks very much. I will double check all of those issues.

Thank you Barry.  I think it was the stereo 1/8 plug.  I still cannot get the Loader to accept the 6.0 update, which shows when unzipped as an "app" or "exe" file, not a DCSt or DCS file.   I'm going to see if I can update remotes now.  Thanks again

If the DCS file is named DCS6_00.EXE, That would actually be the self extracting zip file.  You would need to double-click on that file to extract the 2 files.  One for the TIU (tiu6p00.dcst) and one for the remote (remote6p00.dcsr).  These are the files the Loader needs.

I downloaded the 6.0 software again and it showed up as a dcst file and loaded to the tiu.  My follow the directions to send code to the remote initiated start and it found the 6.00 DCSr file.  At first it said it was loading and asked me to hold release hold release the power button on the remote about 35 times.  Then the power came on on the remote so I shut it down and tried it again only to get the message again that the program is having a hard time finding a tiu ...see photo.  I tried it with two different remotes with the same result.

Since I was stuck on upgrading the remotes I tried to upgrade the software on an older tiu using a serial to USB connection.  This tiu is a REV 13B.  I got critical error message that it did not detect a Serial port.

Kevin,

Did you remove the 1/8" stereo jumper and then power cycle the TIU off na then on again, ensuring that the red LED did blink at least once? If not, the TIU will not be found by the remote update process.

If that's not the case, ensure that the telephone handset cable is plugged into the remote input port and not the AIU port, and that the cable itself is 4-conductor.
