Additionally, GPRSLink, HSPALink, and CDMALink units can be set up to receive incoming connections via the Listening feature. In this case, a program like the Sutron AutoPoll can be used to periodically gather data from X-Link. When scheduled transmissions are set up, X-Link initiates the data transfer; in Listening mode, an application starts the communication with X-Link.

Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 50 5.2. Retransmissions Starting with version 1.57, X-Link is able to make retransmissions (ReTx). Retransmissions are retries of failed scheduled transmissions. When a scheduled transmission fails, X-Link notes the time of the failure. Once a future scheduled transmission succeeds, X-Link will proceed to re-transmit the data from the missing transmissions.
Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 51 5.3. Cell Phone Telemetry GPRSLink, HSPALink, and CDMALink use the cell phone network to connect to the internet and deliver sensor data. The internet connection enables X-Link to get in touch with a server that will accept the sensor data.
Page 52
An X-Link can be set up to always be listening, which means that it will act as a server, accepting TCP/IP incoming connections. Sutron's AutoPoll PC software can periodically reach out to a listening X-Link station and collect sensor data from X-Link.

This application note will show operation using the Type K thermocouple. This sensor outputs a voltage that represents the difference in temperature from the terminal block to the junction of the wires.
Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 105 To have an absolute temperature reading, you must measure the temperature of the terminal strip and then add to it the thermocouple temperature. K-Type Equations: Linear delta T range of ± 20°C. Approximation error is ±0.20°C.

Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 111 The only reason to change X-Link's Timeout setting is if there are SDI-12 sensors connected. The RS-485 bus used to connect to Seametrics is shared with the SDI-12 bus. As long as X-Link is listening for data from the Seametrics flow meter, it cannot collect data from any SDI-12 sensors.

Sutron Corporation X-Link Operations & Maintenance Manual, Rev 1.63 5/24/2016 pg. 123 Time Keeping To keep time, X-Link uses an RTC (real time clock) backed by an internal battery. The RTC keeps ticking even if the main battery to the X-Link is removed. The RTC will, at worst case, drift ±2 minutes per month (0 to +50C).
12.2. SDI Clock Synchronization Certain Sutron SDI-12 sensors (such as the SDR, RLR, and the CF Bubbler) support a command to set the time of the sensor via SDI-12. X-Link takes advantage of that feature, and periodically sets the clock of the sensors using an SDI-12 command, ensuring that all devices share a common time.
