FCC Identification MKZAZY4550MDM FCC Warning This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in an industrial / commercial installation.
1. Introduction ADAM-4550 is an economical, wireless RS-232/ 485 converter designed to interface any bidirectional RS-485 device with a control center host computer. The ADAM-4550 can be used in data acquisition where data sensors are inaccessible to the host computer due to wiring difficulties or long distances that make wiring impractical or impossible. 1.2 Features • Built-in microprocessor • Data transmission speeds up to 115.
1.3 Specifications • Standard • Transmission speed (bps): 300, 600, 1200, 2400, 4800, 9600, 19.2K, 38.4K, 57.6K, 115.2K (transmission speeds are software configurable) • Radio frequency : 2.
2. Installation 2.1 Basic Configuration Before installing the ADAM-4550 in an existing network, the ADAM-4550 unit should be preconfigured. Though all modules are initially preconfigured at the factory, it is recommended that you check the baud rate settings. Factory Default Settings: Baud Rate: 9600 bps (both RS-232 and RS-485) Delimiter: { Address: 00 2.2 Power Supply For ease of use in industrial environments, ADAM modules are designed to accept industry standard +24 VDC unregulated power.
2.3 RS-485 Communication Wiring 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 following standard colors (as indicated on the modules) be used for the communication lines: DATA+ ð (Y) Yellow DATA- ð (G) Green 2.
2.5 Configuring ADAM-4550 1. Insert the ADAM-4550 disk in drive A. Start Microsoft Windows. From the Program Manager, select the File menu and choose Run. Type a:\ADAM4550 and press ENTER. The ADAM Configuration and Diagnostics window should now open. 2. You must now set the host computer’s port configuration before configuring your ADAM4550. To configure your host communication port, select the Setting... menu and choose Local. A dialog box will open.

Note: 1. The address between F8h and FFh are used for non-addressable modules. The addresses for addressable modules are between 00h and F7h. 2. The ADAM-4550 can be configured as either a MASTER type module or a SLAVE type module. The MASTER ADAM-4550 is the module connected to the host PC. The SLAVE ADAM-4550s are those connected to remote RS-485 devices or other ADAM series products. Run your configuration program ADAM4550.EXE to set the unit to the correct type. 6.
3. Select the Upload menu. A dialog box will open. Enter the file name where the firmware to be uploaded is located. Click the OK button to begin uploading. The green LED light on ADAM-4550 now changes to a steady glow. When uploading is completed, the green LED will turn off. Turn off your ADAM-4550’s power and then turn the power on again to complete the uploading process. The ADAM-4550 unit is now ready to be configured. Follow procedures in section A to re-configure the unit.
2.8 Antenna Installation Indoor communication distance is about 300 to 550 ft. using a standard 2 dB antenna. However, actual distance depends on environmental conditions as well as antenna type and positioning. 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. Using ADAM-4550 Connect one ADAM-4550 to the controlling PC’s serial port with the RS-232 cable. Connect remote ADAM-4550 units to remote data units through the RS-485 bus. Configure each ADAM-4550 unit by following the procedures in section A. Start the ADAM Configuration and Diagnostic Program on the controller PC. Select the Setting... 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.

3.1 A Test Sample 1. Follow procedures in section C to install one ADAM-4550 unit as the MASTER module for a controlling PC and two ADAM-4550s as SLAVEs for the remote devices (see Fig. 3). 2. Start the ADAM Configuration and Diagnostic Program on the controlling PC. Select Generate-Traffic menu and choose Send One Packet. In the window area type in {AADDD......

4. ADAM-4550 Command Set 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. two-character address (hexadecimal) that specifies the target module. Depending on the command, an optional data string follows the command string. Every command is terminated by a (cr) carriage return.
