You’re in search of a handheld installation tool, but you couldn’t find what you’re looking for until now? Oh well, you should stop for a while and have a closer look on this AS7010 STMeter, as it might be the thing that you’ve searching for a long time!
The AS7010 STMeter is based on PIC16F877, as it provided sufficient I/O pins to drive an LCD and interface to the keypad. Beside that, the PIC16F877 contains a UART and ADC as well. Hence, the power can be supplied by the maintenance port of the Subscriber Terminal via a step down regulator.
For your information, the AS7010 STMeter is connected to the ST Antenna Unit to give the following information:
- The Visual antenna panning aid in the form of a bar graph (It indicates received signal level automatically)
- The Numeric Receive and Transmit levels
- The Numeric Carrier to Interference levels
- RF channel number and PN code
When you’re attaching the STMeter to the ST maintenance port, the UART will be used to pass information to the main ST processor using a SLIP like protocol. Normally, the received signal strength is shown on the STMeter display as a bargraph.
