LevelMaster 7100 User manual 2105835 Rev AA | 42IMPORTANT NOTES: Referring to a LevelMaster as the "first" serves to identify the unit with the direct connectionto the host controller on a RS-485 bus, once field wiring is completed. The procedures in this section are applicableto the configuration of any additional LevelMasters.Basic configurationBasic parameter configuration includes configuring the LevelMaster ID and baud rate for communication with the host controllerand other LevelMasters. The factory default ID and baud rate are set to 1 and 9600 respectively. Configure as follows:Assign a unique ID. If installing several units, each must have its own ID.Assign the desired baud rate (1200, 9600 or 19200). All LevelMasters on a bus, as well as the host controller, must beconfigured with the same baud rate. Mismatch in communication speed will prevent communication.IMPORTANT NOTES: To manage multiple locations and LevelMasters for large installations, the MasterLinksoftware provides the option to identify LevelMasters and their location by allowing the assignment of location andunit names. This information is automatically retained in a location file created by the software. Several locationfiles can be created to reflect different customer sites, if needed, to keep them separate. Locations and units aredisplayed by the MasterLink main screen in tree view format to ease unit selection for configuration or monitoring.The procedure included in this section assumes that a new location file is being created for the new LevelMaster(s)being installed. Adding the LevelMaster to an existing location, for which a location file was previously created,may require opening the existing file (if it is not the one automatically displayed). If the file was created with aprevious version of MasterLink, click Location from the file menu and select Open Location File. Click on theappropriate file name and click Open.To configure the new board:1. Start the MasterLink version 2.0 software. The main screen displays (Figure 39). If no default location file is opened, thescreen displays no location or existing LevelMasters.Figure 39: MasterLink main screen2. Select location.a. If no location exists or a new location is to be used, right-click inside the screen (white area) and select Add NewLocation.i. Enter up to 25 characters for a location name.
