| 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
