E-Compact MP-BB3 Series
Check if there is any abnormal or differential heating in the connection joints between the
transmitter, filter, antenna, and adder’s imbalance load. If there is any abnormal warming in
an isolated way, this may indicate some flaw or imperfection in that connection. This must
be checked before further increasing the transmitter’s power.
When operating under normal conditions, the modules located at the transmitter’s rear may
reach up to 55°C. This is due to the fan speed control, which is responsible for keeping the
transistor’s temperature at 60°C, as well as the presence of aluminum heatsinks and high
thermal dissipation pallets. All passive devices are located at the rear panel and operate
within the temperature ranges recommended by the manufacturer.
3. Main Operations.
3.1. Power Changing
The alteration of the transmitter power is something possible and accessible to the customer through the
screen POWER SETUP by software navigation Menu in the digital display.
3.2. Communication
Ethernet Communication:
This equipment has a Web Page server accessed by the Ethernet port located on the front
panel of the Module Control CM9001. Once the Control Module is connected to the Switch, this
graphical interface can be accessed by connecting to one of the Switch ports.
USB Communication:
The communication of the digital exciter via USB port, is only possible with the use of the software
GUI8001 (optional).
4. Forbidden operations
There are transmitter parameters which are configured at the factory, parameters defined on the
purchase of the transmitter. There are parameters that are set at the factory - and as previously noted,
were provided at the purchase – which cannot then be changed.
- Channel
- Equipment Model
There are other parameters that are configured in the factory but might be reconfigured using a
password. The careful use of the password is to prevent unauthorized access that can cause the
appearance of a reflected power at the transmitter and consecutively decreasing the value of the output
power of the transmitter due to the protective action of the same.
