  • Page 155 Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 155 Each EXTBUF command must be prefixed with a telemetry indicator and followed with a command option. For example TX1 EXTBUF SHOW will show the data in TX1 (the self-timed) external buffer.

    Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 158 17. Command Line Interface Satlink uses a command line interface. You can use a terminal program instead of LinkComm to talk to Satlink. All of Satlink's features are available over command line. In fact, LinkComm uses the command line interface to talk to Satlink.

    Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 159 The last message received since boot up can be viewed via the front panel, under the diagnostics menu. When Satlink receives a message, it handles the input just as if it were on the commands. For example, issuing the command M1 ACTIVE = OFF would turn off measurement one.

    >STATION NAME = SUTRON DEV 1 Setup changed Station Name = SUTRON DEV 1, max length 23 Changing measurement setup fields requires that the measurement be named. For example, to change the Measurement Type it is not enough to type MEAS TYPE. You need to provide the number of the measurement in question: M1 MEAS TYPE shows the Measurement Type of the first measurement.

    Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 161 To change the current reading of a sensor, type M1 = 12.5. This will change the Measurement Offset such that the said measurement reads the user entered value. For example, if my water level sensor, once set up, read 3.50, and I knew the water level was at 1.50, I would type M1 =...
