Configuring a Wireless WAN Card

296 

IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0

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 

 card, the serial port associated with the wireless WAN card is automatically set to 

. 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 

 for more information).
