2 Installation
The CR4110 is designed for indoor use (office or home). The router should be positioned
on a smooth, level surface making sure that there is adequate ventilation. Do not expose
the router to extremes of heat or cold, strong magnetic fields or liquids.
It is important to remember that these products are wireless devices just like a mobile
phone, so they will only operate reliably over the CDMA network if there is a good signal.
For many applications the stub aerial provided will be suitable but in some circumstances
it may be necessary to use a window-mounted or magnetically mounted aerial with an
extended cable to allow the aerial itself to be positioned to provide the best possible signal
reception. Digi International can supply a range of suitable aerials.
Step 1 - Installing the R-UIM(s)
Note:
Some CDMA-450 networks do not require or support the use of Removable User Identity
Modules (R-
UIM’s), commonly referred to as SIMs on GSM networks. If your service
provider does not support R-
UIMS, your router will be “provisioned” for use on your
chosen network when you receive it and this stage of the installation procedure will not be
required. If your router has not been provisioned, you will need to contact your service
provider to obtain an IMSI and NAI in order to provision the unit manually. See the
configuration section for more details.
The router incorporates two separate cardholders for R-
UIM‟s (SIMs) so that if your
service provider and application demand it, you may install R-
UIM‟s for two different
networks. This means that one wireless service may be used as a back-up service in the
event that the primary service fails in some way. By default, R-UIM 1 is the default R-UIM
that is used for access to the primary network and R-UIM 2 is used for the back-up
network.
Note:
R-UIM1 and R-UIM 2 cannot be used to access two networks simultaneously.
The R-UIM card(s) should be inserted into the cardholders on the right of the front panel
as illustrated below.
