ADAM-4000 Series User Manual
6
This chapter provides guidelines to what is needed to set up and install an ADAM
network. A quick hookup scheme is provided that lets you configure modules before
they are installed in a network. To help you connect ADAM modules with sensor
inputs, several wiring examples are provided. At last, you will find a programming
example using the ADAM command set at the end of this chapter. Be sure to plan the
layout and configuration of your network carefully before you start. Guidelines
regarding layout are given in Appendix E: RS-485 Network.
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 char
-
acters with a 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)
RS-232/RS-485 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 cor
-
rect 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 st24 V
DC
, unregulated power.
Operation is guaranteed when using any power supply b10 and +30 V
DC
.
Power ripples must be limited to 5 V peak to peak while the voltage in all cases must
be maintained b10 and +30 V
DC
. All power supply specifications are refer
-
enced at module 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 30 V input range; therefore, we can assume that the actual drawn current is
inversely proportional to the DC voltage.
The following example shows how to calculate the required current that a power sup
-
ply should provide.
Assume that a +24 V
DC
is used for five ADAM-4011 Analog Input Modules, and the
distance between modules and power supply is not significant enough to cause a DC
voltage drop. One ADAM-4011 module consumes a maximum of 1.2 Watts (W). The
total required power will equal to 5 x 1.2=6 W. A power supply of +24 V
DC
should
therefore be able to supply a minimal current of 6 / 24=0.25 Amps.
Small systems may be powered by using wall-mounted modular power supplies.
Also, when modules operate in long communication lines (>500 feet), it is often more
reliable to obtain power locally through modular power supplies. These inexpensive
units can be easily obtained from any electronic retail stores.
