2.4.5.2 Enabling 802.11 Networking

The SCS has 802.11 networking enabled by default. This allows the SCS to check for a compatible wireless

networking card at startup. If a compatible card is present, the SCS will use the wireless network and ignore

any wired Ethernet settings. If no compatible PC card is present, the SCS will use the 10/100BASE-T

Ethernet interface.

If you want the SCS to only look for a wired Ethernet connection, you must disable 802.11.

Figure 2-20: Disabling 802.11

Note: You must reboot the SCS after enabling or disabling 802.11 networking.

2.4.5.3 802.11 Region

When using 802.11 networking, you must make sure the SCS is configured for the correct regulatory

region. Configuring this option incorrectly may cause the SCS to broadcast on frequencies that are illegal

in your area. The factory default setting is correct for the United States; users in other countries should

change it to a value appropriate for their area before attempting 802.11 operation.

Other region settings are listed in Set/Define 80211 Region on page 12-28. In the following example, IC

sets the region to Canada.

2.4.5.4 MAC Address

A MAC address is a unique identifier that distinguishes different devices on the 802.11 network. It is the

same as the unit’s hardware address. The SCS can be configured to use either the PC card’s MAC address

or its own internal MAC address (the default) with the Set/Define 80211 MAC Address command. For

seamless operation when switching between wired and wireless networking, use the SCS’s MAC address.

2.4.5.5 Extended Service Set ID (ESSID)

Whenever there is more than one ESS in a wireless LAN architecture, each device needs to be told which

ESS it belongs to. The ESSID ensures that devices communicate with the right AP.
