T-D
Disable RS-485/422 receiver terminator
T-E
Enable RS-485/422 receiver terminator
[T-E] setting enables the internal 120 ohms terminator on the receiver
interface. A proper termination is important in a bus topology or multi-
drop network. The terminator is a resistor added in parallel with the
receiver's "A" and "B" lines in order to match the data line characteristic
impedance and reduce signal reflection. This setting is useful when the
converter is installed at the end of a RS-485 or RS-422 bus.
If the internal 120 Ohm terminator is not appropriate for your application,
use [T-D] to disable it and use external one.
