CHAPTER 2System Setup32to provide your own "crossover" network cable, which you can findin most computer stores. If you plan to use the Base Station as astandalone unit (that is, without a computer), you need a tele-phone line and an external modem, connected to the A850 eitherby USB or to the connector marked “modem”.Note: Before you operate the Base Station, Adcon strongly recom-mends that you charge the internal battery to a level whereit can sustain the operation of the Gateway. You can do thisby plugging the power cable into the A850 device while dis-connecting the serial cable from an A440 outdoor unit for atleast six hours.Initialize the Base StationIn order to be able to use your A850 Telemetry Gateway for thefirst time, you have to initialize it through its Console Interface bymeans of the Terminal emulation program Hyperterm (as, e.g., pro-vided by WINDOWS operating systems as accessory, and alsoavailable for download from the internet). The initialisation encom-passes some basic steps establishing your ownership and disposi-tion of the device. Details are described in chapter 5.Note: Before initialising the Gateway, the Installation of the indoorunit and of the outdoor unit has to be performed.License of the GatewayThe Gateway software can enforce some limitations depending ona license key:• the number of RTUs that can be inserted,• the number of sensors that can be inserted,• the number of Wireless Modems that can be inserted (withregard to the planned “multiple A440 support”),• the number of dialup-modems that can be inserted,• the number of GPRS pseudo-modems that can be inserted,• an expiration time for the license.
