This section includes:

• system operation description, including example sets of

operation commands

• baud rate, cable length, and power limitations

• detailed command descriptions

• data formats

• instructions for deploying and recovering the SBE 38

Sampling Modes

The SBE 38 has two sampling modes:

• Polled Sampling – take a single sample on command

• Continuous Sampling – sample continuously; start when power is applied

or on command, depending on the setup

Descriptions and examples follow for an SBE 38 with RS-232 Interface. Note

that the SBE 38’s response to each command is not shown in the examples.

Review the sampling modes and the commands described in Command

Descriptions before setting up your system.

Polled Sampling

The SBE 38 takes one sample of data on command. Transmission of data to

the computer is dependent on the particular command used.

Example: (user input in bold)

Apply power and establish communications. Set up to average 4 measurements per sample and output converted

data with 3 digits after decimal place. Command SBE 38 to take a sample and send data to computer.

(Apply power and then click Connect on Toolbar.)
