    Subject: microair transponder/encoder hookup question
    Has anyone successfully installed a Microair T2000SFL-01rev8 transponder combined with their EC2002-01rev3 encoder, using serial connection? The manual for the xp rev8 at > http://www.microair.com.au/admin/uploads/documents/T2000SFLInstallationManual01R80.pdf shows *2* data lines between the components: encoder pin6data receive to xp pin 5data transmit, and encoder pin 7data transmit to xp pin 4data receive. *But*... note 7 on the hookup page (pg 13) says that the diagram is applicable to revs 5,6, & 7. I can't find an install manual for the 01rev3 encoder on their web site, but the manual for the 01rev12 shows pin 6 of the encoder (labeled rs232in) as unconnected. However.... Looking at the page on their pre-wired harnesses at http://www.microair.com.au/index.aspx?page=186&productID=36 The diagram for wiring their xp to their encoder shows encoder pin 6 (data receive) to be *grounded*. So, various docs on the Microair website show the encoder pin 6 to be: open, tied to transponder pin 5, and grounded (through the harness) to the case of the transponder. Anyone have any words of wisdom on the *right* way to do it? Thanks, Charlie <http://www.microair.com.au/index.aspx?page=186&productID=26>
