TT455-RT-238
If comport2 is connected to a computer,
then wire a female connector as shown.
If you control anything else then you might
need a male connector and/or different
wiring.
Contact us for assistance or read this
simply explained “get started guide”
on RS232:
http://lintronic.dk/rs232.pdf
This setup will allow TT455-RT-238 to receive
bluetooth signals on comport1 as an RS232
command.
The TT455-RT-238 can use the incoming RS232
command as a trigger, but can optionally send a
copy of the RS232 command to the computer.
In the Memory Map
Input/Output tab
set this checkbox
if you want the
bluetooth copied to
the computer.
The computer can send your Memory Map to the TT455-RT-238, making it very easy to both create
your TT455-RT-238 functionality and then test it by bluetooth in the same wiring.
