Satlink Logger s data merge capability allows Satlink to handle two kinds of transmission data External data is data given to Satlink from another device such as Sutron s Xpert data logger Sensor data is data collected by Satlink from sensors directly connected to it External data has its own buffer This buffer is large enough to handle the maximum amount of data that can be sent in a single transmission 12 kilobytes Satlink will automatically empty this buffer after a transmission unless the Circular Buffer option Advanced Scheduled Tab of the Communicator program has been selected in which case any unsent data gets kept for the next transmission The user may limit the amount of data that gets sent by using the Window Centering Scheduled Tab of the Communicator program option The buffer will also get emptied when the user starts Satlink and upon power up External data should be given to Satlink about 60 seconds prior to transmission If there is a desire to give the data closer to transmission Satlink needs to be asked until when data is accepted into the buffer There exists a command that can be sent to Satlink via the serial port to find out just how close to a transmission the data can be given If the data is given too late it is sent in the next transmission Sensor data gets stored in a buffer that holds the last 32 readings of each of the 16 measurements This data gets lost upon power up Both External and Sensor d

DI 12 devices can return more than one sensor reading such as a water quality probe that returns Dissolved Oxygen Conductivity Temperature etc Some of these devices will return more than one reading when issued a single measurement command and others require that multiple measurement commands be given In the case of the devices that return more than one reading to a single measure command the SDI 12 specifies which of the sensor readings returned by the SDI 12 device to use Setting the parameter to 1 tells Satlink Logger to use the first value returned from the device setting parameter to 3 tells Satlink Logger to use the third value returned from the device If more than one parameter needs to be measured a different measurement needs to be set up for each parameter These measurements should have identical setups except for the SDI 12 Param Be sure to keep the measurement time and interval the same for these measurements If you vary the time and interval Satlink Logger will end up taking multiple measurements rather than retrieving multiple values from the same measurement In the case of devices which require multiple commands to be issued e g 0M1 retrieves pressure OM2 retrieves temperature multiple measurements need to be set up It does not matter if these 5 IT O N 21300 RIDGETOP CIRCLE STERLING VA 20166 WWW SUTRON COM 703 406 2800 703 406 2801 FAX SALES SUTRON COM 50 SATLINK 2 LOGGER AND TRANSMIT
