However the Telegesis Terminal Application Software program allows
enhanced functionality especially suited to the ETRX2 modules. The AT-Style
commands can be issued by clicking on customisable „Command‟ buttons and
all of the 64 bit serial numbers which are reporting in are listed in a separate
window. This means you will not need to input any of the 64 bit serial numbers.
For instructions on how to use the AT-Commands read the AT Command
Manual and the ETRX2 wireless meshing module user guide.
After installing the Telegesis Terminal Application program the command
buttons for firmware R2xx based on EmberZnet2.x or R3xx based on
EmberZnet3.x will be shown at the bottom of the window. Use File -> Open
Layout to select the correct set of buttons. In order to use the Telegesis
Terminal software, select the correct COM port and the connection parameters
(ETRX2 default 19200, 8 bits, no parity, no flow control) and press the
“Connect” button. These settings are automatically retained each time the
software is re-started.
To get started quickly, power up one node connected to the PC and type AT
followed by <enter>. If the communication to the module is working the module
will prompt OK, if not check power and serial connections and make sure you
have connected to the correct COM port.
3 Network Set-up with Telegesis AT commands
To start a PAN network issue the AT+EN command, or alternatively press the
„Establish PAN‟ button. The local unit will now scan all available 16 channels
and establish a PAN with a random PAN ID on the quietest one. This may take
up to 16 seconds and leads to the node becoming the network‟s coordinator.
When successful the module will prompt „JPAN:cc,PPPP‟1, where cc is the
channel number and PPPP is the PAN ID of the newly created PAN.
If you get an error message instead it is likely that the module was already part
of a PAN, so you need to issue the AT+DASSL command or press the „Disas
Local‟ button to leave the PAN before going back to starting a new one. In
order to find the network status simply issue the AT+N command or press the
„NWK Info‟ button.
Once the network is established remote nodes can be powered up ready to join
in. If you have serial access to remote nodes simply issue the AT+JN
command or press the „Join any PAN‟ button to join the newly established
PAN. If you don‟t have serial access to the remote nodes (such as with the
three MCBs provided with the DVKA) you just need to wait for them to join the
network automatically.
