STEP 6: Placement Options
In addition to placing the TCC-100 on a desktop or other horizontal surface,
you may also use the DIN-rail or wall mount options, as illustrated below.

Termination Resistor Diagram
Termination is designed to mitigate
noise from the RS
-422/485
s. If the network
long, undesirable
-line effects could arise.
The best method for mitigating
energy on an unused conductor is to
dissipate the energy as heat by
terminating both ends of the unused
conductor to ground with resistors (this method is called bi-directional
termination).
The resistance of the resistors should be equal to the
characteristic impedance of the line. The most common RS
-485 twisted
stic impendence of 100 to 120 ohms. Moxa’s
termination technique is bi
-directional termination, which offers excellent
signal integrity. With this technique, the line drivers can
be located
