connector. When modules are powered remotely, the effects of DC
voltage drops must be considered.
All modules use on-board switching regulators to sustain good
efficiency over the 10 to 48 V input range; therefore, we can assume
that the actual drawn current is inversely proportional to the DC voltage.
Figure 2-1 Power Supply Connections
We advise the following standard colors (as indicated on the modules)
for each power line:
+Vs (R) Red
GND (B) Black
Communication Wiring
We recommend the use of shielded-twisted-pair cable in the ADAM
network for reducing interference purpose, but the cable has to comply
with the EIA RS-485 standard. Furthermore, only one set of twisted-
pair cable is required for transmitting Data. We advise the following
standard colors (as indicated on the modules) for each the
communication line:
DATA+ (Y) Yellow
DATA- (G) Green
