I Just Had To Tell Somebody

 Not sure when they stopped putting the VHS tape in. I know my first one came with the tape when DCS was new to the market. I'm not really up on all the versions. I just purchased 2 new ones. My previous 3 were all different models. The very first versions if you pop the cover off. Weren't equipped with fuses.

You have an original Rev. G from about 2002-2003.

Thanks Barry,  Are there any precautions, other than the commonly implemented fail safes, that I should be aware of?  Currently I am using a Z4000 for power.  As Dave C. suggested the Rev. G may not be equipped with internal fuses.  I do not plan to use this TIU as my primary source for layout control as it was purchased to be used as a Back-Up if that becomes necessary sometime down the road.

Thank you for the reply!

Not really. Just be sure to have a 10-amp fast-blow fuse in the Hot wire between the transformer output and the TIU's channel input for each channel that you're using.

Also note that unmodified (by MTH) Rev. G TIUs are considerably more prone to failure than any of the later models. In addition to not having internal fuses, they had lighter traces and lacked the later DCS signal generator protection of all subsequent TIU models.

Further, unlike later TIUs, the Rev. G had all of its Common wires connected internally. That isn't necessarily a bad thing, however, it is a difference of which you should be aware.

This and a whole lot more is all in “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at OGR’s web store!

Barry,

Thank you again for your time and responses.   I truly appreciate the valuable information pertaining to the Rev. G TIU.
