ripples must be limited to 5 V peak to peak, while
voltage must in all cases remain between +10
and +30 VDC. All power supply specifications are
referenced at the module connector.
2.1 Basic Configuration
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.
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.
Factory Default Settings:
Baud Rate: 9600 bps (both RS-232 and RS-485)
Delimiter: {
We advise that the following standard colors (as
indicated on the modules) be used for power
lines:
Address: 00
+Vs
ð (R) Red
2.2 Power Supply

2.3 RS-485 Communication Wiring
Note: 1. Before turning on the power and
configuring the ADAM-4550, make sure it is
connected to your host computer through an
RS-232 cable and that the host computer is
on. The ADAM-4550 will automatically detect
the cable and set itself as a DTE/DCE
according to the RS-232 port of the connected
host computer. If there is no RS-232 cable
connected to the host computer, the ADAM-
4550 will set itself as a DCE when you turn on
the power.
For RS-485 wireless transceiver applications,
the user can leave the RS-232 port opened.
The ADAM-4550 should set RS-232 as a DCE
after power is turned on.
2. The pin INIT (pin 6) should be grounded while
you turn on the power of ADAM-4550 for config-
uration. For normal operation, just leave INIT
(pin 6) open while you turn the power on.
We recommend using shielded-pair cables which
comply with the EIA RS-485 standard to reduce
interference in an ADAM network. Only one set
of twisted-pair cables is required to transmit both
DATA and RTS signals. We advise that the fol-
lowing standard colors (as indicated on the mod-
ules) be used for the communication lines:
DATA+ð (Y) Yellow
DATA- ð (G) Green
2.4 Software Configuration
The ADAM-4550 comes with a setup disk that
contains software for the following:
• Baud rate configuration
• Address configuration
• Statistical RF error rate retrieval
•Firmware upload tool for firmware upgrades

2.8 Antenna Installation
Note : 1. While using directional antennas, care
should be taken to install and adjust the anten-
na‘s direction according to the instructions of
the antenna’s manufacturer. Please see the
example specification for an external 24 dBi an-
tenna at appendix A.
Indoor communication distance is about 300 to
550 ft. using a standard 2 dB antenna. Howev-
er, actual distance depends on environmental
conditions as well as antenna type and position-
ing.
2. A user’s license may be required to use a
directional antenna. Please consult your local
authority for local regulations.
Longer communication distances can be
achieved by using an antenna with a higher gain.
A table of communication ranges as a function
of differing combinations of antennas (at the
source and receiving ends) is displayed below.
3. We strongly recommend that you install
ADAM-4550 as near as possible to its antenna.
Where the antenna has to be located at a dis-
tance from the ADAM, special RF cable is re-
quired. Please see the example cable connec-
tion arrangement in appendix B.

3. Using ADAM-4550
connected to the controlling PC, as well as the
green LEDs on the remote ADAM-4550 units
should now be in a rapid blinking mode. This
indicates that the RF links between the control-
ling unit and all the remote units have been es-
tablished.
Connect one ADAM-4550 to the controlling PC’s
serial port with the RS-232 cable. Connect re-
mote ADAM-4550 units to remote data units
through the RS-485 bus.
Configure each ADAM-4550 unit by following the
procedures in section A.
Note: It is important that during the initial set-
up, the ADAM-4550 unit connected to
the controlling PC must be powered up
before the other remote ADAM-4550
units are powered up. Moreover, any
devices connected to an ADAM-4550
through RS-232 must be powered on be-
fore the ADAM-4550 is powered on.
This will allow the ADAM-4550 to auto-
matically detect the connected device
and set itself into proper DCE or DTE
modes.
Start the ADAM Configuration and Diagnostic
Program on the controller PC. Select the Set-
ting... menu and choose Local. In the dialog
box, select the proper COM port and set the baud
rate to the one configured for the ADAM-4550.
Make sure all ADAM-4550 units are powered
off. From the ADAM Configuration and Diag-
nostic Program, select the Connections menu
and choose Connect. Turn on power to the
ADAM-4550 connected to the controlling PC and
the green LED should blink slowly. Turn on the

4. ADAM-4550 Command Set
two-character address (hexadecimal) that spec-
ifies the target module. Depending on the com-
mand, an optional data string follows the com-
mand string. Every command is terminated by
a (cr) carriage return. Command sets are divid-
ed into two categories: configuration mode
commands and data pass mode commands:
In order to avoid communication conflicts, all
actions are instigated by the host computer when
several devices attempt to send data at the same
time . The basic form is a command/response
protocol with the host initiating the sequence.
The host issues a command to a module with a
specified address and waits a specific amount
of time for the module to respond. If no re-
sponse is received, a time-out command aborts
the sequence and returns control to the host.
Syntax
[delimiter character] [address] [command] [data]
[carriage return]
Every command begins with a delimiter charac-
ter. Most of the commands can use a $ (dollar
sign) or a % (percentage sign), but the Data Pass
mode command uses one of eight special char-
acters. The delimiter character is followed by a
