b. A laptop can be used to connect directly to the RS-232 port at the station using astandard 9-pin serial cable. Do NOT use a null modem cable.2. Verify all sensors are functioning correctly.3. Verify the weather station clock and set as necessary.NOTE:The ET107 comes with a default program (see Default programs (p. 103)).NOTE:Use standard time in the station if calculating. Do not use daylight savings time.6.7 Communication peripheralsCommunication kits ordered with the enclosure are pre-mounted and pre wired; no furtherconnections inside the enclosure are necessary. Follow the external installation procedures inlater sections to make the external connections.If you received a telecommunication kit separate from the enclosure, follow the “InternalInstallation” procedures outlined in later sections. Schematics for the phone and short haulmodems are in Communication modems schematics (p. 82).Default settings for the data logger in the ET107 station:l PakBus address 1l RS-232 Port: Autobaud (300 to 115,200 bps)l ME: Autobaudl SDC7 or SDC8: 115,200 bps6.7.1 Direct connect to ET107 stationThe ET107 station does not require an interface device for direct RS-232 communication. Theinside of the enclosure has a RS-232 and CS I/O port available for communication (see FIGURE6-22 (p. 37)). Most standard communication options use the CS I/O port leaving the RS-232 portfree for direct communication with a laptop or desktop computer using a standard RS-232 serialcable. The data logger used in the ET107 station can communicate with more than one device ata time allowing troubleshooting to be done in the field with a laptop while remotecommunication devices are accessing the station.Section 6.
