2.3 Jumper Setting
We designed the ADAM-4500 with ease-of-use in mind. It has three jumper settings. The
following sections explain how to configure the module. You may want to refer to the figure below
for help in identifying card components.
The following diagram shows the locations of the jumpers:

different applications. Jumper settings are shown below:

2.4 Communication Wiring
The ADAM-4500 offers two serial ports: COM1(3F8) in RS-232 or RS-485, and COM2 (2F8) in
RS-485. COM1 can be configured as an RS-232 or as an RS-485 interface via the jumper setting.
This provides flexibility for communications between the controller and other devices in your
application.
