Configuring a USB Modem
Configuring a USB Modem
Overview
SCS IOLAN models support a USB Wireless Modem that can be installed to permit access to the
IOLAN via the internet or other WAN network. If you are using a PCMCIA Wireless Card, See
Configuring a Wireless (PCMCIA) WAN Card . When the PCI card type has been configured to be
USB, the serial port associated with the USB Modem is automatically set to PPP. No other PPP
configuration is typically required. The USB Modem 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).
