The average gets timestamped with 16:00. However, the actual maximum value of 31.248 happened at 15:24 and the minimum value of 25.661 happened at 15:15.
Page 99 10.3.2 Measure Type: Precip Accumulation and Precip Rate Connection: Terminal #12 TB/DIN#2 and Terminal #11 Ground Precip Accumulation and Precip Rate are designed to measure the pulses from a tipping bucket type rain gauge. Precipitation accumulation is used to tally the total amount of precipitation since the station has powered up.
Page 100  Accu Reset Month (default is 0)  Accu Reset Day (default is 0)  Accu Reset Hour (default is 0) By default, when the station is setup for a Daily reset, it will reset accumulation at midnight of the next day.
Page 101 Power loss and Precip Accumulation Precip accumulation information is stored in persistent memory. It is not lost when power is removed. After it is powered on, and after the first Precip Accumulation reading is made, an accumulation reset may occur. The reset will be made if an accumulation reset interval has been missed. For example, take a station setup for Daily rests.
Page 102 When a count measurement is calibrated, the count tally for that input is set to zero, and the measurement's Offset is to the calibrated value. For example, setting Precip Accumulation reading to 10.2 will clear the tally for TB/DIG IN 2, and set the measurement's Offset to 10.2. 10.3.3 Measure Type: SDI-12 SDI-12 sensors traditionally connect over the SDI-12 bus:...
Page 103 Setting the parameter to 1 tells the station to use the first value returned from the sensor; setting parameter to 3 tells the station to use the third value returned from the sensor. If you want to record (and transmit) more than one parameter from a single SDI-12 sensor, a different measurement needs to be set up for each parameter.
Page 104 To send a command to an SDI-12 device, enter the Address and Command fields, and then press the Send button. Be sure to select the proper port. The results of the command are shown in the SDI-12 history window. To have the station look for any and all sensors on the SDI-12 bus, press the Find Devices button. Information regarding what sensors are found is displayed in the SDI-12 history window.

While sometimes referred to as a single-ended input, it is designed to measure voltage with respect to analog signal ground.
Page 106  The negative voltage (or positive voltage) must remain within the range of the differential input range selected.  The common mode input range of the differential inputs must not be exceeded (see below). While the differential inputs are capable of reading negative voltages, it is important to keep the voltages with respect to ground within in the common mode input range of 0.5 to 3.7 volts.
Page 107 using an accurate 100 Ohm resistor, the overall loop resistance is 200 ohms due to an additional 100 Ohms series protection resistor. This means that a sensor at a full 20 ma current output, approximately 4 volts should be allotted for overhead voltage. This is typically not an issue when an external voltage source is provided to operate the sensor that may be in the 18 to 24-volt range.

10.3.10 Measure Type: Internal Temperature Internal Temperature measurements use a temperature sensor installed inside every unit. The reading provided is in degrees Celsius. To convert from Celsius to Fahrenheit set the slope to 1.8 and the offset to 10.3.11 Measure Type: Modbus The system may be setup to collect data from Modbus sensors.
Page 115 If both Equations and Slope and Offset are used, Slope and Offset are applied after the equation is processed. For example, to convert Fahrenheit to Celsius, type into command line: M1 EQUATION = (X-32.0)*5/9 In the example above, X refers to the sensor reading. LinkComm comes preloaded with equations for many types of sensors.

Page 118 When a station goes into or out of alarms, the reading causing the alarm is logged. Additionally, an event is recorded in the log. The station can be set up to send transmissions when it goes into alarm. Alternatively, the station can be set up to make a transmission when it goes into alarm and to make another transmission when it goes out of alarm.
Page 119 For example, if a High Alarm with the Threshold of 10.5 and a Deadband of 3.0 were setup, the system would go into alarm once the reading was equal to or greater than 10.5. The system would stay in alarms as long as the reading was equal to or greater than 7.5.
Page 120: Alarm Computation Details
10.6 Alarm Computation Details This section contains details on how the system decides whether to go into alarms. The section is broken down by the user chosen Alarm Type setting: 10.6.1 Hi Alarm When the Alarm Type is set to Hi, if the sensor reading is greater than or equal to Alarm Threshold, the station goes into alarm.
Page 121: Logging Settings
ROC alarm scenario:  System measures stage every 15 min  ROC Alarm threshold is at 2ft  Tx Alarm Interval is 5min (not relevant)  If the most recent stage minus the prior sample is 2ft or greater, the system sends out an alarm transmission.

Page 123 For example, if one wanted to measure and log data once a minute, one would set the Measurement and Logging Intervals to one minute. Since it may be expensive to transmit all that data, one can choose to transmit only every 10th reading by setting the Tx Data Interval to 00:10:00. The example below uses Measurement and Logging Intervals of 15 minutes.

Page 125: Multiple Measurements Using The Same Sensor
10.11 Multiple Measurements Using the Same Sensor You can set up multiple measurements with the same input. For example, to log the daily rainfall and the rainfall during the last hour, set up two measurements: one as a precipitation rate with an interval of one hour, and another as precipitation rate with an interval of one day.
Page 126: Telemetry Setup
11 Telemetry Setup XLink features a built-in modem which is used for telemetry. XLink will collect sensor data and later transmit that data to a remote destination. The telemetry setup manages the transmission of data. Just as there are multiple measurements that may be setup, there are multiple telemetry setups. Each setup is independent of another.
Page 127 When the station should make a transmission depends on the transmission schedule. The time is computed based upon these settings:  Scheduled Time  Scheduled Interval The interval controls how frequently the transmission is made, and the time controls when the transmission is started.
Page 128: Cell Setup
If the Alarm Interval is zero, alarm transmissions are made once when the station enters alarms, and optionally a second time when the station goes out of alarms. 11.1.6 TX Format The TX Format field controls how the sensor data is formatted in the message. Each format has its own distinctive advantages.
Page 129 11.2.1 Data Source This setting determines whether the station will transmit measured sensor data (traditional setup) or files (created by Python scripts and saved to a specific folder on the SD card). Options are  Measurement  File This setting should only be changed to File in order to transmit files created by Python scripts on the SD card.
Page 130  FTPS is also supported – enable the Secure option to use FTPS.  The system supports explicit FTPS.  HTTP  The station may deliver data to Hydromet Cloud using HTTP or HTTPS. Enable the Secure option to use HTTPS. ...
Page 131  /ottml.htm?ws=99 FTP Path This setting may be used to deliver FTP data to a specific path on the server. Please note that the station CANNOT create directories. The path must exist on the FTP server before the station can deliver files to it. An example of a path: “Rain_station/A2/B12”.
Page 132 When the front panel button is pressed, and when the station goes into alarms, listening is automatically turned on for one hour. When the cell modem is powered on, the station will act as a TCP/IP server, ready to accept incoming connections from LinkComm if Accept TCPIP Connects is enabled.
Page 133 Whitelist In order to further protect the station from unwanted access over the internet, whitelisting may be used. A whitelist contains a list of IP addresses (or address ranges). Unless a client is on the list, the client will not be able to connect to the station using TCP/IP. Please note that if Accept TCPIP Connects is off, whitelisting is not relevant.
Page 134 Accept SMS Accept SMS controls whether the system will accept any incoming SMS. It is enabled by default. If Accept SMS is disabled, the station will not accept any SMS. Disabling this setting strengthens the security of the station. Prior to version 8.21, there was a setting called SMS Listening Only which prevented the station from opening a listening socket.

 Some SIM cards are locked with a PIN. This setting holds the value to give to the SIM when turning the modem on. A locked SIM will not work without a PIN and the station will report a Bad PIN error. ...
Page 136 Iridium Listening If enabled, Iridium Listening will cause the station to keep the Iridium modem on all the time. This results in messages sent to the station being received near immediately. This reduces the data costs associated with connecting to the Iridium gateway in order to check messages. In this mode, the station will reset the modem once a day for reliability, resulting in at least one connection to the gateway daily.
Page 137: Additional Telemetry Settings
Iridium Enable The Iridium Enable setting may be used to completely disable the Iridium modem. If disabled, the station will never power on the modem, and no Iridium features will be available. This setting is the equivalent of disconnecting the modem from the board. It may not be set remotely. Iridium Tx Station Name This setting controls whether Iridium telemetry should include the station name in the header of the message.
Page 138 end up with inconsistent transmission data content. In that case, disable Skip First Missing, and increase the Sensor Cutoff Offset. Sensor Cutoff Offset helps prevent missing data in a transmission by specifying how old the newest measurement in the transmission may be. The default value for the offset is zero. Let us continue with the example above.

Page 160: Missing Data Retrieval
13.3 Missing Data Retrieval In the case of transmission failures, XLink offers several ways of retrieving the data from the missing transmissions. 13.3.1 On-Site Data Retrieval To retrieve missing data when on-site, download the station’s log. Either use a USB thumb drive or connect to the station with LinkComm in order to download the log.
Page 161  6:BATT 0 #10 10.887 11.032 11.232 10.971 11.316 11.111 :TEMP 0 #10 28.25 28.25 28.00 28.25 27.75 27.50 Please note that the station simply replies to the command with the data. In this example, the station was asked for data via Iridium, so it replied via Iridium. If it had been asked via RS-232, it would have replied via RS-232.
Page 162: Retransmissions
13.4 Retransmissions XLink is able to make retransmissions (ReTx). Retransmissions are retries of failed scheduled transmissions. The goal of retransmissions is to automatically retransmit data that was in the failed transmissions. 13.4.1 How Retransmissions Work When a scheduled transmission fails, the system notes the time of the failure. Once a future scheduled transmission succeeds, the system will proceed to re-transmit the data from the missing transmissions.
Page 163: File Transmissions
If the station does not have any data logged for the relevant time period, no retransmission will be made. Loss of power cannot be overcome with retransmissions. Retransmissions are only useful if the station is still able to collect and log sensor data. Data older than 7 days will not be retransmitted.
Page 164: Logging
14 Logging XLink automatically logs the sensor data that it collects (see 10.7 L ). Data is logged on OGGING ETTINGS secure flash memory with a capacity of over 1,000,000 entries. Each log entry uses an IEEE 64 double precision float to represent the sensor reading. Log usage and capacity information is available in the main status.
Page 165: Log Events
The downloaded data is in Sutron Standard CSV format and can be easily displayed using Sutron’s GRAPHER program (downloadable from ) or common spreadsheet/word processing SUTRON programs. You can download the whole log or only parts of it. You may specify the start date and optionally the end date for the downloaded data.
Page 166 This means that if a SDI-12 sensor takes 1 minute to provide a result, and the measurement is setup to go every 15 minutes, the measurement will start at 00:15:00 and complete at 00:16:00. The logged data will have the timestamp of 00:15:00. The system handles averaged readings in such a way that the last sample is collected at Meas Time + Meas Interval.
Page 167: Errors
15 Errors During operation, the system may notice errors. If it does, it will blink the red LED on the front panel. To see the error details, check the status with LinkComm. Via command line, type STATUS to see any potential errors.
Page 168: System Errors
15.2.3 Sampling Too Short This happens when the sensor response time is longer than the sampling interval. SDI-12 readings are a good example: if a sensor requires 10 seconds to produce a reading, and the sampling interval is 10 seconds, this error gets set. 15.2.4 Averaging Too Short The averaging interval is either shorter than the sampling interval or than the sensor reply time.
Page 169  Two or more consecutive transmissions failing cause an error.  If more than 25 percent of total transmissions fail, an error is flagged.  If no measurements are set up to be included in the transmission data, the system flags an error. 15.3.5 Hardware Failure This error is recorded if any hardware issues were noted since boot up.

16 Transmission Data Formats 16.1 Pseudobinary B Data Format This format is based on GOES Pseudobinary format. It is used when the user selects Pseudobinary B as the choice for Tx Format. The format uses ASCII characters. Three bytes are used for each data value. To correctly decode the measurement, you need to know how many readings of each measurement are included in the transmission.
Page 171 Field Pseudobinary B for Scheduled and Alarm Txs The range of the Pseudobinary number is -32 to +31 and can be converted to volts by multiplying by 0.234 and adding 10.6 allowing a range of 3.1 to 18.1 volts.

Page 183 When Protocol is set to Hydromet Cloud, the station will engage in handshaking with the server. The station will provide the server with information about the transmission that includes the station name, password, reason for the transmission, and error checking information. The server will acknowledge the transmission.
Page 184: Iridium Telemetry Header
9. To acknowledge, the server needs to send a single byte: <cr> Once the server sends the byte, the station will disconnect. 10. To initiate a command line session, the server sends user login command !LOGIN=username,password<cr> and waits for the station to reply (ETX.) If user login matches, the station enters command-line session.

Page 187: Command Line Interface
17 Command Line Interface XLink uses a command line interface. You can use a terminal program instead of LinkComm to talk to the station. All features are available over command line. In fact, LinkComm uses the command line interface to talk to the station. When messages are sent to the station via SMS or Iridium, they use the same format as regular command line communications.
Page 188: Status
Units with a cell modem can receive SMS (text messages). Units with an Iridium modem can have messages sent to via emails that get routed through the Iridium system. See the section 13.1.4 S ENDING ESSAGES TO THE TATION VIA RIDIUM The last message received since boot up can be viewed via the front panel, under the diagnostics menu.
Page 189 data is shown. If a measurement is not active, it will not show its setup fields. If a measurement is of type analog, it will not show its SDI-12 setup fields. The command SETUP NONDEFAULTS only shows the fields that have been changed from defaults. An easy way of setting up your station is to type WIZARD or just W.
Page 190: Measurements
Setting the whole setup to defaults can be accomplished by typing SETUP DEFAULTS. Setting just measurement one to defaults can be done via M1 SETUP DEFAULTS. 17.5 Measurements To view the setup and the last reading made measurement one, type M1. Use M2 for measurement two, etc.

 tank level  temperature  tide and sea state  turbidity  water velocity  weight of snow and ice on a snow pillow  wind speed and direction Sutron also offers general purpose interfaces for making analog and digital measurements via SDI-12. For more information on SDI-12, go to -12.
Page 202: Useful Sdi Commands
This is important to ensure that data from one sensor is gathered at the same time and for sensors that have multiple parameters that take a long time to process. 18.5 Useful SDI commands Resetting the address by software (some sensors) is normally done by sending the aAb! command. (a A b !, where a is the current address of the sensor you want to change and b is the address you want to change to, e.g., 0A5! changes the address of sensor 0 to address 5.) Another useful SDI-12 command is the aI! (where a is the address of the sensor, e.g., 3I! for sensor at...

19 Modbus Modbus is a communications protocol commonly used in industrial applications. Please see the IKIPEDIA for more details. ENTRY  The station can be configured as a Modbus server or as a limited Modbus client.  In Modbus client mode, the station collects data from Modbus sensors. ...
Page 205: Modbus Hardware Interface
19.1.2 The Station as a Modbus Client The station is capable of operating as a Modbus client. It can collect data from sensors using the Modbus protocol. When setup to collect data from Modbus sensors, the station will periodically issue a client read register message on the data bus.
Page 206: Modbus Setup
The station will assert RTS before sending data out the port in order to key off a radio. The station also drives DTR whenever Modbus is active. 19.2.3 Troubleshooting Modbus If there are Modbus communications issues over RS-485 or RS-232, there are two potential causes: ...
Page 207 Modbus Rs232 Server Enable Modbus Rs232 Server Device ID Modbus Rs232 Server Delay before Tx 0 ms Modbus Rs232 Server Delay after Tx 0 ms Modbus Rs232 Protocol Modbus Rs232 BaudRate 19200 Modbus Rs232 Parity Even Additionally, if the station is to collect data from Modbus sensors, it needs to have a measurement setup for each Modbus sensor.
Page 208  ASCII (usable on RS-232 and RS-485)  TCP (usable on Cell only) RTU is the most basic Modbus protocol and is commonly used for directly wired systems. It requires a robust connection as it has stringent timing requirements. The ASCII protocol is most forgiving of timing issues and will produce the best communication results when communicating over a modem.
Page 209 Modbus Server Delay before Tx Default is 0ms. This identifies the number of milliseconds to wait before starting data transmission. This is useful if the device is connected to a radio requires keying initialization before data transmission. This is a Modbus server setting only. There is no delay when the station is a Modbus client. Modbus Server Delay after Tx Default is 0ms.
Page 210: Modbus Server Function Codes
 Float is a IEEE 32 bit floating point value.  Double is a IEEE 64 bit floating point value.  Discrete means that the sensor returns one byte and that the result is based on the least significant bit of the byte. Modbus MSW For certain Modbus Value (Int, Uint, Float, Double), Modbus MSW determines which register is used to contain the most significant word (MSW) of the tag's value.
Page 211 Holding Registers Holding registers are reserved for the purpose of setting and getting data such as the date and time and diagnostic counts if the ability to send the above Diagnostic (0x08) command is not available. The following table identifies the holding registers and their locations. Each of these registers is an unsigned 16-bit value (if readings registers using an Xpert, set the data type to ushort).
Page 212 Modbus Last registers Measured measurement Battery Voltage Internal Temp M1, M2, .. M32 refer to measurements. E.g., to read the last measured sensor value for measurement M10, read registers 19 and 20 and combine the result into a single 32 bit IEEE floating point value. 19.4.2 Calibrating Measurements by Writing to Modbus Registers It is possible to write to the station’s Modbus Holding Registers in order to calibrate measurements.
Page 213: Sutron Function Codes
19.5 Sutron Function Codes This section describes the use of the Sutron function code to get files, send files and, get the log over MODBUS. This only applies when the station is a Modbus server. The data portion of a packet carrying the Sutron function code (function code 65, or 0x41) contains a subcode and associated parameters to define the particular function to perform.
Page 214 The datetime value in the response message is the datetime of the returned record and, therefore, may be different from the datetime in the GetLog command statement. The data to the end of the file can be read by leaving datetime at the desired starting point and incrementing recordID until the status indicates record not found.
Page 215 GFR,status,totalbytes,start,numbytes,data status will have one of the following values: Value Description File not found. Get beyond file end. Record not found. Command format error totalbytes will be set to the byte size of the whole file. It is not the number of bytes returned in this retry! The client station should issue repeated GetFile commands until it has received totalbytes amount of data.
Page 216 Status information If the file "status.txt" is asked for, the data returned will be similar to what LinkComm shows on the Main Status and on Telemetry Status. Sensor data Access recent measurements and setup details by asking for the file "sensors.txt". The data in the file will describe the measurement setup along with the most recent readings.
Page 217 numbytes is the number of data bytes in the payload. For Modbus over RS-485, this number must not be greater than 48. data should contain actual setup data. Example: STATION NAME = HAPPY CREEK M1 MEAS INTERVAL = 00:00:30 The format of the reply is as follows: SFR,status,bytepos,numbytes The value of status can be any of the following values: Value...
