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.
