4.3.1 Enabling internal termination
Model 2400S PROFIBUS-DP transmitters have a switch on the user interface module to enable
internal termination impedance. Refer to Figure 4-2.

Note: The Model 2400S
PROFIBUS-DP transmitter does
not have terminals for termination
wiring. An external terminator is
not required. The transmitter has
an internal terminator. There is a
switch on the user interface for
enabling internal termination. See
Section 4.3.1.
