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 applica-

tion 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 or 300

Ohms).
