Rapidport
Rapidport offers an easy solution for remote access via Plug-and-Play USB connectivity. This external, user-
installable solution plugs into the USB port of a PC, thin client or server and provides four 56K V.90 modems.
EdgeUSB technology, shipping with Rapidport since 1998, adds Plug-and-Play USB compatibility to Microsoft
Windows NT and Windows NT Embedded system users. The Rapidport gives network users access to Internet
Service Providers (ISP), fax, and other group dial-up applications supported by Windows NT RAS.
Rapidport is a scalable solution – its onboard USB port enables additional units to be stacked and daisy-chained as
modem requirements increase. The downstream port may be used to connect and power any 500mA USB peripheral
device, including Edgeport
USB-to-serial converters for instant I/O expansion. Its feature-rich design, extensive
operating system support and reliable performance make Rapidport/4 ideal for mission critical enterprise
applications.
Cabling Rapidport
To connect the cables included with your Rapidport:
1) Connect one end of the power supply* into the back of your Rapidport and the other end into an AC outlet.
2) Connect one end of the phone cord** to Port 1 on the back of the Rapidport and the other end to an analog
phone jack. Repeat for up to four connections (Ports 1-4).
CAUTION
: To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
3a) For a downstream connection, plug the Type A end of the USB cable into the USB port located in the back of
your PC
or
into an available USB port on a standard hub
or
into a Digi International Hubport. Plug the Type B
end of the USB cable into the back of the Rapidport.
3b) For an upstream connection, plug the Type A end of the USB cable into Rapidport’s USB Type A slot and
the Type B end of the USB cable into the upstream device (e.g. a Hubport or another Rapidport).
The cabling diagrams on page 10 show both Type A and Type B plugs and receptacles.
