Communication Status
There is one LED on the panel of ADAM-4510I and
ADAM-4520I module. Its purpose is to show the com-
munication status:
Power Supply
For easy use in industrial environments, the ADAM
modules are designed to accept industry standard +24
VDC unregulated power. Operation is guaranteed when
using any power supply between +10 and +48 VDC.
Power ripples must be limited to 5 V peak to peak while
the voltage in all cases must be maintained between +10
and +48 VDC. All power supply specifications are ref-
erenced at module connector.
The power cables should be selected according to the
number of modules connected and the length of the
power lines. When using a network with long cables,
we advise the use of thicker wire to limit the line volt-
age drop. In addition to serious voltage drops, long volt-
age lines can also cause interference with
communication wires.
We advise that the following standard colors
(As indicated on the modules) be used for power lines:
+Vs (R) Red
GND (B) Black
Communication Wiring
We recommend that shielded-twisted-pair cables that
comply with the EIA RS-485 standard be used with the
ADAM network to reduce interference. Only one set of
twisted-pair cables is required to transmit both data and
RTS signals. We advise that the following standard col-
ors (as indicated on the modules) be used for the com-
munication lines:
DATA + (Y) Yellow
DATA - (G) Green
Basic Configuration
Before placing a module in an existing network, the
module should be properly configured. The two follow-
ing diagrams show typical layouts for both modules:
