Section 4 Basic Configuration via Browser Interface
This section describes a few more basic concepts, as well as how to establish a wireless link 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 that you read the other sections of this manual to gain an
understanding of all important configuration parameters and procedures prior to deploying your equipment.
In this section you will:
• Learn about AP and SU Basic Configuration Screens and Parameters
• Populate the 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 M900S uses the concept of “association” to indicate that the APs and SUs are communicating. If all
parameters are properly set, the AP will begin actively searching for the SUs in its SUDB. Once an active SU is
detected, the authentication and association process will begin.
Essentials for Establishing a Wireless Link with M900S Series Radios
• Base ID in AP and SU must match
• MAC Address of SU must match an entry in the SUDB
• SU must be set to “autoscan” all channels, or it’s channel must be fixed on the same channel as the 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’s Subscriber Unit Database (SUDB)
Prior to establishing a wireless link, the user must configure the 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, and 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 SU’s in the same sector,
without the need for a router. Only SUs with the 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.
The default setting for switch #3 is OFF.
CIR UP: Committed Information Rate from SU to AP. Minimum upstream data rate (measured in
Kbps) at which the SU will attempt to deliver bandwidth to the AP. Maximum setting is
3000.
