Connecting to a Computer or other Device
The Ethernet port of your RLXIC-EH 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-EH 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-EH'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-EH 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-EH has a standard mini-B connector.
Warning:
The USB port can only be used in a non-hazardous environment.
4.3 Indicator
Lights
When your RLXIC-EH is connected to power and
an antenna, there is a specific pattern to the lights
to indicate its operation mode.
Network
- Indicates a successful connection
to the cellular network with an IP address
given, and a channel acquired.
Signal
- Light shows the strength of the
signal, and may be nearly solid (strong signal)
or flashing (weaker signal). A slow flash
indicates a very weak signal.
