CR4110 Installation Guide

1 Introduction
The CR4110 is a compact IP router that facilitates the transmission of data over 3G
wireless CDMA EV-DO 450 networks at downlink speeds of up to 3.1Mbps and up-link
speeds of up to 1.8Mbps depending on network conditions.
EV-DO 450 networks provide a wireless, IP-based data transmission service using an
“always-on” protocol which means that once the router has “attached” to the network, data
can be transmitted and received on demand, i.e. it is not necessary to make a call first.
Data transmission rates on Rev A networks may be up to 3.1Mbps in the receive direction
and 1.8Mbps for sending which makes them suitable for a wide variety of applications.
The routers can be configured either by using commands entered at the serial port (much
like a modem), or via the built-in Web interface. We recommend that you use the Web
interface whenever possible.
In addition to many standard LAN and Internet protocols such as PPP, the CR4110
provides a combination of powerful but easy to use configuration, management and
diagnostic tools. This makes it a simple and cost-effective solution for migrating existing
terminal or telemetry equipment, which use wired networks (PSTN, ISDN, etc.), to
wireless operation.

USB Host Connectors
The USB host connectors may be used to connect compatible USB 2.0 client devices
such as memory sticks, serial adapters, etc. Note that the total current available to power
USB devices is collectively 0.5A (i.e. for both ports).
Status Indicators
The status indicators operate as follows:
ON
Illuminates steady red when power is applied.
LAN
Illuminates steady when there is a network connection to the LAN port
and flashes when data is transmitted or received.
