Termination resistor setup
You can install termination resistors if necessary for impedance
matching. The card has mounting spaces for termination resistors, but
no resistors are installed at the factory. Depending on your application
you may need to solder in a single resistor to handle the DATA+/
DATA- pair (and a corresponding resistor on the other end of the
connection). The value of the resistor should equal the characteristic
impedance of the signal wires (approximately 120 Ohms).
Termination resistors TR1 ~ 4 handle Port 1
Termination resistors TR5 ~ 8 handle Port 2
Termination resistors TR9 ~ 12 handle Port 3
Termination resistors TR13 ~ 16 handle Port 4
