Autotrac Interface
The Autotrac transceiver provides bidirectional satellite
communications between the weather station and the Autotrac software
package of the end user. In addition, the transceiver contains a GPS
receiver for acquiring location and accurate time information. The
QML logger has been tested with the Qualcomm transceiver, referred to
as the Omnitracs/Autotrac option in the Device list of Lizard Setup
Software.
Configuring Autotrac Transceiver
Hardware Setup
The Autotrac transceiver is connected to the QML logger using RS-232

configuration parameters for the module:
- Data speed: 1200 bps
- Data bits: 8
- Stop bit: 1
- Parity: None
In the Devices view, add the transceiver to the setup. Under I/O
Connections, connect the transceiver to the previously configured
communication module.
Device Configuration
The Autotrac transceiver is configured in the Device configurations
view as shown in
