External Interfaces
1.3.1
Ethernet connection
The capt
2
web module contains a full duplex 10
/
100Mbps Ethernet interface. Use the CAT5 cable supplied to connect
the device to an Ethernet switch or directly to a computer. The interface is Auto-MDIX capable. It requires no special
cable, such as a crossover cable, to directly connect it to a computer, but the connection type is automatically
recognized.
Instructions for the configuration of the Ethernet interface, especially IP settings, can be found in chapter
6
and
7.3
.
1.3.2
USB interface
capt
2
web provides a
full-speed USB on-the-go
port on its Mini-USB connector. The
USB on-the-go (OTG)
functionality
allows the capt
2
web module either to act as an USB device or Host depending on the type of end point connected to
it. This provides maximum flexibility.
Host mode:
the port supports USB mass storage devices for continuous data logging. See chapter
5
for details.
Client Mode:
capt
2
web module acts as a CDC device providing a console interface to configure your device and
display information about it. See chapter
7
for details.
