Murata Electronics North America Z2430A Manual Do Utilizador

This section describes in detail all the features and functions of the development board that 
makes up the developer’s kit. The development board as it comes from the factory is labeled as 
a Router on the bottom of the board. Additional Router or End Device development boards can 
be ordered from RFM.  
 
A block diagram of the development board is shown below: 
 

 

 
The USB and RS-232 interface circuits convert standard level signals into 3.3V transmit and 
receive data signals. Only one input can be used at a time. If a USB connection is present, the 
RS-232 input will be electrically locked out. Note that there is no hardware flow control 
implemented on the RS-232 input. A standard RJ-11 connector is provided for the RS-232 
connection. 
 
The development board can run off either a 9Vdc power source or a 9V alkaline battery.  The 
supplied wall-mount DC power supply connects to the DC power connector located next to the 
USB connector. The 9V alkaline battery connectors are located on the bottom of the board 
underneath the Power LED. 
 
A JTAG header is provided for situations where custom profiles or module code is being 
developed and the module will be programmed without using the bootloader code resident in 
the module.  
 
All of the ZMN2405HP module pins, except Reset, are brought out to connectors on the board. 
This facilitates connecting the module to other devices without having to integrate the module 
into another circuit. The pinouts of the connectors are listed below and are included in the board 
silk screen for JP1 and JP2.
