Campbell Scientific COM320 Voice Communications Modem - Manual (Page 35)

Appendix B. Updating and Configuring
the COM320
The COM320 has an internal USB port for connecting the mode to a computer.
Connection to a computer is required to install the drivers, download an
operating system, change COM320 settings, and retrieve a vocabulary list.
The COM320’s case must be removed to access the USB port
(see Section B.1). NOTE
B.1 Removing the Cover to Access the USB Port
1) Use a Philips screwdriver to remove the five screws on the sides of the
COM320.
2) Lift off the case.
B.2 COM320 USB Communications Cable
The COM320 uses a USB Type-A Male to Type-B Male cable (Campbell
Scientific #17648) for updating firmware, vocabulary and configuration. This
is a common USB cable used with USB connected printers and scanners.
B.3 COM320 Driver Installation
If this is the first time a COM320 has been plugged into your computer, it will
be necessary to install the drivers to enable communication with the COM320.
The driver is available from the
www.campbellsci.com/download (under
“View by Download” select COM320 USB Driver). Assuming that you have
already downloaded the driver to your computer, this procedure should walk
you through the path of installing the driver on Windows XP. In order to install
this driver, follow this procedure:
1) Remove the cover of the COM320 to access the USB port (see Section
B.1).
2) Connect a USB cable between the COM320's USB port and one of your
computer's USB ports.
3) Power the modem by connecting the modem’s green 12V and G terminals
to a 12 Vdc power source or by connecting the modem to the CS I/O port
of a datalogger.
