Connecting the target board

J-Trace connects to the target board via a 38-pin trace cable. This cable has a recep-
tacle on the one side, and a plug on the other side. Alternatively J-Trace can be con-
nected with a 20-pin JTAG cable.
Warning: Never connect trace cable and JTAG cable at the same time because
this may harm your J-Trace and/or your target.
