Swap the tx and rx lines on the Arduino. Swap back to reconnect to PC.

Is the shield explicitly powered? It may be being phantom powered from
the control lines when connected to the PC which are not present when
connected to the Thunderbolt.

In the RS-232 world devices are either DTE or DCE. You need one of
each on each end of the line if using a normal straight cable.To
connect two like devices you need a crossover cable (AKA "null modem")
From the sounds of it I'm guessing the PC is a DCE and the Arduino
and Thunderbolt are
That sounds a lot like you have the Thunderbolt's TX pin hooked up to the
RS-232 Shield's TX pin, which is what would happen if you tried to use the
same cable that worked between the Shield and the PC or between the
Thunderbolt and the PC. To connect the Shield and the Thunderbolt you might
just n
You have TX connected to TX? Swap your TX/RX connections and see if the
levels improve.

Hello,
I'm integrating an Arduino (Due/Mega have tried both) with a surplus
Thunderbolt and need some advice.
The Thunderbolt is a known working unit (supplies 10Mhz to my HPSDR rig) and
the serial interface works fine between it and a PC. I've read the coverage
about this kind of integrati
