ADAM-4550 User's Manual

Before installing the ADAM-4550 in an existing
network, the ADAM-4550 unit should be pre-
configured.  Though all modules are initially pre-
configured at the factory, it is recommended that
you check the baud rate settings.

Baud Rate: 9600 bps (both RS-232 and RS-485)

Delimiter: {

Address: 00

For ease of use in industrial environments,
ADAM modules are designed to accept industry
standard +24 V

DC

 unregulated power. Modules

are certified for operation with any power sup-
ply source between +10 and +30 V

DC

. Power

ripples must be limited to 5 V peak to peak, while
voltage must in all cases remain between +10
and +30 V

DC

. All power supply specifications are

referenced at the module connector.

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 voltage drop. In addition to serious
voltage drops, long voltage 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

ð

(R) Red

GND

(B) Black
