How to log onto the Elpro 245U-E-A Radios
1. Power up the 245U-E-A
2. Open your web browser e.g.
Internet Explorer
3. Type in the IP address of the
Radio into the browser e.g.
192.9.200.74 in this example.
4. If you get a warning message
just click “Continue….”
•NB: Make sure your computer is on the same IP range as
the radio. The default IP range of the radios is 192.168.0.xx
•The default subnet mask is 255.255.255.0
•You should be able to PING the radio from your PC
* Refer to Section 3.2 of the User Manual
Note: Supply Range 9 –30Vdc

Checking Connectivity
The following example assumes the setup below:
•For information on how to setup your 245U-E-A radio
device refer to section 3.25 of the User Manual
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
[e-mail]

Go onto the Access Point Configuration Home Page
Then, click on “Connectivity”
[e-mail]

Connectivity information: AP Webpage
Shows that this AP is connected to device IP
192.9.200.75
Connected on Channel 149
Connectivity Rate is 18Mbps.
Note: this is NOT the actual
throughput but max possible RADIO
throughput. Actual throughput will be
roughly half this but must be tested
(see later section)
RSSI = Received Signal Strength = -74dBm
BGND = Background Noise = -84dBm
RSSI Connectivity Rate
-74dBm (or stronger) 54Mbps
-90dBm 18Mbps
-94dBm 6Mbps

Connectivity information: AP Webpage
Access Point can have several
Clients shown in this window.
[e-mail]

Connectivity information: Client Webpage
Clients only connect to a single Access Point
Site Survey will show any other wireless AP’s
including the one it’s currently connected to.
RSSI Connectivity Rate
-74dBm (or stronger) 54Mbps
-90dBm 18Mbps
-94dBm 6Mbps

Checking Channel Utilization
The following example assumes the setup below:
•For information on how to setup your 245U-E-A radio
device refer to section 3.25 of the User Manual
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
Channel Utilisation gives a visual display of how busy the current channel is over a given time period.
[e-mail]

Checking Channel Utilization
Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system
Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system
Channel Utilisation gives a visual display of how busy the current channel is over a given time period.
E.g. 1 Relatively Quite Channel
E.g. 2 Relatively Busy Channel
[e-mail]

Checking Channel Utilization
Click on “Channel Survey” from the device Home Page
•Channel Utilization shows both seconds, mins and hours. It
also include the average background noise for each time
interval
•On average, you don’t want your channel utilization to be
higher than around 75%
•If you don’t have a lot of traffic on your system, this value
should be relatively low. If it’s high it could indicate the
presence of other interfering systems.

Throughput Testing
•A low throughput can be an indication of either a busy
channel or low signal strength
•Always test throughput on an idle channel where possible
Throughput testing measures the maximum data throughput that can be achieved.
[e-mail]

Throughput Testing
Note: Make sure “Enable IPERF Server” is selected on all devices you want to test
•To get to Advanced Radio Settings:
•Click on “Radio”
•Then “Advanced Radio Settings”
[e-mail]

Throughput Testing
Under “Throuput Test” type in the IP address of the remote device you want to test
E.g. At the AP you would type the remote Client device IP
Average Throughput is 8.85Mbps
[e-mail]

Throughput Testing –Interpreting the result
The table below shows the expected results for both internal and external throughput testing.
This is an example of internal throughput testing, which always yields slightly lower results.
Your internal results should match up relatively closely to the tables values below.
