Section 4 Basic Configuration via Browser
Interface
This section describes a few more basic concepts and how to establish a basic wireless link between AP
and SU using the Browser (HTTP) Interface. This section is written to address only the most basic steps
in establishing a link in the lab, or a bench-top environment. It is highly recommended to read the other
sections of this manual to gain an understanding of all important configuration parameters and
procedures prior to deploying any wireless equipment.
In this section you will:
• Learn about AP and SU Basic Configuration Screens and Parameters
• Populate AP’s Subscriber Unit Data Base (SUDB) with at least one SU
• Configure Other Basic AP Parameters
• Configure Basic SU Parameters
• Establish a Wireless Link
• Evaluate Link Quality
The M2400S uses the concept of “association” to indicate that the AP and SU’s are communicating. If all
parameters are properly set, the AP will begin actively searching for the SU’s in its SU database (SUDB).
Once an active SU is detected, the authentication and association process will begin.
Essentials to Establish a Wireless Link with M2400S Series Radios
• Base ID in AP and SU must match
• MAC Address of SU must be entered into the AP(SUDB)
• SU must be set to either “autoscan” all channels, or it’s channel must be fixed on same channel
as AP.
• AP must be in Opmode “on”
• SU must be in Opmode “on”
• Adequate signal strength must be received at each radio
If all of these parameters are met, the wireless link will automatically establish itself and Ethernet traffic
will begin to pass between the radios.
Note: This section utilizes the Browser Interface as the configuration tool. For the equivalent
procedure using CLI commands, see Section 5.
Configuring the AP Subscriber Unit Database
Prior to establishing a wireless link, the user must configure the subscriber unit database (SUDB) in the
AP with each SU’s MAC address and related settings. The SUDB includes information about each SU.
Click on the Subscriber Database page to add, modify, or delete SUs. The key information for each SU
includes the following:
SU ID: User Definable subscriber unit ID (1…126)
TYPE: PR Priority or REG Regular. Priority SUs are polled much more frequently than
regular SUs. Priority SUs in general will respond to the AP with less latency than
regular SUs.
Group: SU to SU Group # (1..F in hex) for SU to SU communications within the same sector.
Note: This SU to SU feature allows interconnectivity between multiple SUs in the
same sector, without the need for a router. Only SUs with same SU to SU group #
may communicate with each another. If you do not want the SUs to communicate
with each other, choose N/A for SU to SU group. In order to use SU to SU
communication, AP switch #3 must be ON. Default setting for switch #3 is OFF.
