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….”

Note: Supply Range 9 – 30Vdc

• 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

Checking Connectivity

The following example assumes the setup below:

Device Mode: Access Point (AP)

IP address: 192.9.200.74

System Address (SSID): system

• For information on how to setup your 245U-E-A radio

device refer to section 3.25 of the User Manual

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

RSSI = Received Signal Strength = -74dBm

BGND = Background Noise = -84dBm

192.9.200.75

Connected on Channel 149

RSSI Connectivity Rate

-74dBm (or stronger) 54Mbps

-90dBm 18Mbps

-94dBm 6Mbps

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)

[e-mail]

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

Channel Utilisation gives a visual display of how busy the current channel is over a given time period.

The following example assumes the setup below:

Device Mode: Access Point (AP)
IP address: 192.9.200.74
System Address (SSID): system

• For information on how to setup your 245U-E-A radio

device refer to section 3.25 of the User Manual

Device Mode: Client (STA)
IP address: 192.9.200.75
System Address (SSID): system

[e-mail]

Checking Channel Utilization

Channel Utilisation gives a visual display of how busy the current channel is over a given time period.

E.g. 1 Relatively Quite Channel

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.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

Throughput testing measures the maximum data throughput that can be achieved.

• 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

[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.
