4  Operating Instructions 

4.1  Power-on Operation 

Upon power up, the transmitter loads any stored parameters present in its nonvolatile memory. If parameters have 
not been stored previously, the transmitter initializes default parameters and then stores them in the first preset slot, 
0. There are a total of 16 available software-based presets (0 through 15) for saving multiple parameters at once for 
future use. 

4.2 

nanoTX™ Serial Control Protocol 

The nanoTX™ is controlled via a simple three-wire serial interface (transmit, receive, and ground). The serial port 
configuration is as follows: 

•

 

57600 baud rate (changeable depending on the configuration option) 

•

 

8 bits 

•

 

No parity 

•

 

1 stop bit 

•

 

No flow control 

For setup and configuration via a standard Windows-based PC, you may use HyperTerminal. For a more flexible, 
full-featured control interface, we recommend Terminal, available for download from the Quasonix website 
(Documents tab > Accessories link) or directly at: 
http://www.quasonix.com/sites/default/files/terminal_ver20080315.zip. 

If the terminal program is active when power is applied to the transmitter, the following welcome message displays, 
as shown in Figure 27. At this point, you can verify that your serial connection is active in both directions by issuing 
any standard command, such as “FR” to learn the frequency.
