APPLICATION NOTE NO. 68 Revised June 2009

Using USB Ports to Communicate with Sea-Bird Instruments

Most Sea-Bird instruments use the RS-232 protocol for transmitting setup commands to the instrument and receiving

data from the instrument. However, most newer PCs and laptop computers have USB port(s) instead of RS-232 serial

port(s).

USB serial adapters are available commercially. These adapters plug into the USB port, and allow one or more serial

devices to be connected through the adapter. Sea-Bird tested USB serial adapters from several manufacturers on

computers at Sea-Bird, and verified compatibility with our instruments. These manufacturers and the tested adapters

are:

• FTDI (www.ftdichip.com) -

“ChiPi” USB-RS232 Converter (model # FTDI UC232R-10).

Note: This adapter can also be purchased from Sea-Bird, as Sea-Bird part # 20200.

Drivers for this adapter can be found at http://www.ftdichip.com/Drivers/VCP.htm.

• IOGEAR (www.iogear.com) –

USB 1.1 to Serial Converter Cable (model # GUC232A).

Note: We have had several reports from customers that they could not communicate with their instrument using a

laptop computer and this adapter.

• Keyspan (www.keyspan.com) -

USB 4-Port Serial Adapter (part # USA-49WLC, replacing part # USA-49W)

Note: We have one report from a customer that he could not communicate with his instrument using a notebook

computer and this adapter. He was able to successfully communicate with the instrument using an XH8290 DSE

Serial USB Adapter (www.dse.co.nz).

• Edgeport (www.ionetworks.com) -

Standard Serial Converter Edgeport/2 (part # 301-1000-02)

Other USB adapters from these manufacturers, and adapters from other manufacturers, may also be compatible with

Sea-Bird instruments.

We recommend testing any adapters, including those listed above, with the instrument and the computer you will

use it with before deployment, to verify that there is no problem.

See Application Note 56: Interfacing to RS-485 Sensors for information on using a USB port to communicate with a

Sea-Bird instrument that communicates via RS-485 telemetry.
