2.1 System Requirements to set up an ADAM network
The following list gives an overview of what is needed to setup, install and
configure an ADAM environment.
• ADAM modules
• A host computer, such as an IBM PC/AT compatible, that can output
ASCII characters with an RS-232C or RS-485 port.
• Power supply for the ADAM modules (+10 to +30 V
DC
)
• ADAM Series Utility software
• ADAM Isolated RS-232/RS-485 Converter (optional)
• ADAM Repeater (optional)
Host computer
Any computer or terminal that can output in ASCII format over either RS-
232 or RS-485 can be connected as the host computer. When only RS-232
is available, an ADAM RS-232/RS-485 Converter is required to transform
the host signals to the correct RS-485 protocol. The converter also provides
opto-isolation and transformer-based isolation to protect your equipment.
Power supply
For the ease of use in industrial environments the ADAM modules are
designed to accept industry standard +24 V
DC
unregulated power. Opera-
tion is guaranteed when using any power supply between +10 and +30 V
DC
. Power ripples must be limited to 5 V peak to peak while the voltage in all
cases must be maintained between +10 and +30 V
DC
. All power supply
specifications are referenced at module connector. When modules are
powered remotely, the effects of line voltage drops must be considered.
All modules use on-board switching regulators to sustain good efficiency
over the 10-30 V input range, therefore we can assume that the actual
current draw is inversely proportional to the line voltage. The following
example shows how to calculate the required current that a power supply
should be able to provide.
