Configuring a Wireless WAN Card
Overview
SCS IOLAN models support a wireless WAN card that can be installed to permit access to the
IOLAN via the internet or other WAN network. When the PCI card type has been configured to be a
Wireless WAN card, the serial port associated with the wireless WAN card is automatically set to
PPP. No other PPP configuration is typically required. The wireless WAN card will establish a GPRS
data connection over the service provider’s GSM network. The service provider will assign an IP
address to your wireless connection. This address may be public or private and it may be dynamically
or statically assigned, depending on the type of account established with the service provider. If a
static, public IP address has been assigned, the IOLAN will be directly accessible via that IP address.
If a dynamic, public IP address has been assigned, you may access your IOLAN with the assistance
of a dynamic DNS service provider. These service providers provide a method of accessing your
device server using a standard URL (for example, yourcompany.dyndns.org), when the IP address
assigned by the Wireless provider is dynamic. The IOLAN SCS supports dynamic DNS updates to
DynDNS.com (see
www.DynDNS.com for more information).
