1. Monitor and Control Interface

The control system is used for a variety of functions, the most important of which is ensuring that the amplifier system continues to operate properly. The control system also allows the user to monitor and control the amplifier via front panel, and remotely through the parallel DB25 Connector and Ethernet UI.

1.1. Network User Interface

In order to access the network interface, the Power Meter unit must be connected to the local network or accessed directly using an Ethernet cable connected to the top of the controller. The default network configuration is:

IP Address          10.0.0.10
Subnet Mask        255.255.255.0
Gateway              10.0.0.1
Nameserver        10.0.0.1

By default, the network interface is available at http://10.0.0.10

MAIN PAGE

Network Configuration

The Ethernet card is provided with a static IP address. The default address is 10.0.0.10. If the default IP address does not fit with the local network configuration connect an Ethernet cable from a computer directly to the device in order to update the network settings. Configure the computers IP address to any available IP address in the range 10.0.0.2 -­ 10.0.0.254 in order to access the web interface. Once connected, use the Network Configuration link from the main page to access and update the network settings.

The Network configuration page provides access to set the IP address, Subnet Mask, Gateway, and DNS. The current network setup is shown in the Network Information box. Input the desired values and then click on the submit button to confirm the change. DNS is optional. All other fields are required.

WARNING ­- Changing the network configuration could render the system unreachable. IP address changes will not redirect automatically.

Once the IP address change has occurred, access to the web interface is now available from the new IP address specified in the network configuration page. Note: The computer network configuration may need to be edited to reflect the new IP address.

Alerts Page

The Alerts page allows for configuration of threshold levels required for fault conditions. A checkbox allows for the SMTP notification email to be enabled or disabled. (check = enabled).

Descriptions to the right of the input boxes provide details of the fault displayed and the condition that causes it to occur. Faults are available on the Ethernet network interface (GUI and SNMP), and the DB9 Remote Connection.

Reports Page

Active fault conditions (see section 8.5) are stored by date and time of occurrence in the format: YYYY-MM-DD HH:MM:SS.ms. They can be viewed by clicking the Load Data‘ button and downloaded to a .csv file by clicking the Download CSV‘ button. Clear previously recorded history by clicking the `CLEAR‘ button.

Report Data Clear

Clicking the Clear button will load a confirmation page. Click the Clear button to confirm the Report Clear action. WARNING ­- Data is unrecoverable.

After the Report Data has been cleared a confirmation message will appear

Note: If the report data does not display correctly clear the web browsers cache.

1.2. SETUP

The SETUP page allows for the Site Name and Site Location to be updated. The Site Name and Location information is displayed on the GUI and will be sent out with SMTP email alert notifications.

System Date and Time will be picked up automatically from a network time server, however, if no time server or Internet connection is available, the user may set the time and date manually.

1.3. SMTP PAGE

Broadcast Electronics provides a setup-free SMTP option via SMTP2GO. Modifications to this page are only required if you would like to use your own email server to send SMTP Email.

1.4. SNMP

The SNMP MIB file can be downloaded by accessing the page snmp.html from your assigned IP address. The default address is: http://10.0.0.10/snmp.php

The SNMP page also allows for the SNMP service to be enabled and disabled. The user may also select between SNMP v2c and the more secure SNMP v3. Please not the user account created under the Users page will be used to access SNMP v3. The password requirement for SNMP is a minimum of 8 characters.

The BE MIB file allows access to the following data via the SNMP protocol:

private/enterprise/be/beProducts/beTransmitter

Read Only

1.5. LCD Display

The LCD display on the front panel provides operation information. Monitoring includes Forward Power (FWD), Reflected Power (RFL), Current (CUR), Voltage (VLT), Temperature (TMP1, TMP2) and FAULT Status. When a fault is not present the fault indication is “NONE”(no fault present). When a fault becomes active the LCD will display the fault, and depending on the condition, will implement corrective actions. See section 8.5 Fault Conditions.

1.6. Fault Conditions

Fault conditions are displayed on the web GUI and the front panel LCD. They are stored in the history and can be downloaded as a .csv log file.
