There are a number of options for connecting to a Fetch instrument for testing and configuration purposes before deployment, this article discusses how to connect using an acoustic transceiver.

Connecting to a Fetch to run some basic tests before deployment can be done with any 6G transceiver, for example a Dunker 6 or one of Sonardyne’s USBL High Performance Transceivers (HPTs).

First, connect the transceiver to a power source and PC COM port. Make the connection between the transceiver and computer via the RS232 link from a PC running the 6G Terminal Lite software.

With this software running on your PC, click connect and select the applicable COM port. Hold your transceiver close (within 10 cm) to the Fetch transducer and you can start communicating directly with the Fetch instrument.

When testing Fetch with a transceiver, perhaps the easiest way to go is to use manual commands via 6G Terminal Lite. Open the manual commands tab and first set a low power level and low linear gain in your transceiver for in-air testing by applying the “CS:LG#,TPL#” command where # represents the numbers you select for power and gain (example: CS:LG6,TPL170).

To then test your Fetch with the transceiver, input manual commands into the input field such as those detailed in the table below.

Where aaaa = acoustic address; W1 = wake-up signal 1; and hhhhhh = UID

Alternatively, testing Fetch with an acoustic transceiver can be done by navigating to the 6G Setup tab in the 6G Terminal Lite software as described in the ‘Functional testing’ section in your Fetch manual.
