3. Using ADAM-4550
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.
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 power to the remote ADAM-4550 units one by one. The green LED on the ADAM-4550 that is
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.
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.
