C-6 ADAM-5000
RS-485 Network
Combination of an ADAM-4000 and an ADAM-5000 in a
RS-485 Network
The following figure shows how to integrate ADAM-4000 and
ADAM-5000 systems in a network.

Note: The speed of ADAM-4000 and ADAM-5000 in a RS-
485 network should be the same.
C.2 Line Termination
Each discontinuity in impedance causes reflections and distortion.
When a impedance discontinuity occurs in the transmission line the
immediate effect is signal reflection. This will lead to signal distortion.
Specially at line ends this mismatch causes problems. To eliminate this
discontinuity, terminate the line with a resistor.
