"The secondary serial port is available on pins 7 and 8. A “Y-adatper
cable” can be built to separate the primary and
secondary serial ports to separate connectors. When a splitter cable is
used, it is recommended to connect the computer
to the primary port (pins 2 & 3) and the GPs to the secondary port (pins
7 & 8)."
I tried it that way too if I reverse the connections (i.e.) GPS plugged
into PC port and so on no GPS LED blinking on the TT4 and still no
connection.

There's mention in the configuration manual about whether you are using
a null modem cable and/or a splitter. It's on page 4 of the Quick Start
Guide.
