4.2 Connecting to a Computer or other Device
The Ethernet port of your RLXIC-EV can be connected directly to a computer or
other Ethernet device with either a crossover cable or a straight-through cable.
The Ethernet port on the RLXIC-EV is auto-sensing and connects at 10Base-T. If
you are connecting the modem to a hub or switch you should use a straight
through cable or use the uplink port on the hub o4 switch with a crossover cable.
Tip: On some computers, the TCP receive window may be set to 16 Kbytes. To optimize the
throughput of your RLXIC-EH, it is recommended that you change the TCP window to 128 Kbytes
to 256 kbytes using a TCP Optimizer.
Your RLXIC-EV's full-speed (12 Mbit) USB 2.0 port can
be connected directly to most computers or other devices
using a standard full-speed USB 2.0 cable. If the
computer or device you are connecting or the cable is not
rated for full-speed, the modem will communicate at a
reduced speed to match. The RLXIC-EV functions as a
device, not a host.
When it is connected to a computer, the USB port should be seen as a COM port
or Ethernet port after the applicable driver is installed.
The RLXIC-EV has a standard mini-B connector.
Warning: The USB port can only be used in a non-hazardous environment.
