join the Hub/network if they are configured with the same frequency and link
configuration as the hub and have sufficient signal strength to communicate with it.
11. Enter the Site Name (optional). This is a convenient name for the location or site and
can be used by operation staff for identification. Its value does not affect radio
operation. Up to 15 characters can be entered. This name is used by the optional
Network Performance Software (NPM) to display the status of sites and send alerts. It is
recommended that a unique name be given to each site.
12. Click on SET to make the desired Configuration changes within the ATR. The ATR will
automatically reset and begin using the new configuration information. Allow about 7-
10 seconds for this process to complete. And then press the Get button to verify the
new information is stored within the ATR. This information will be saved permanently
within the ATR until changed in the future and will not be lost if the ATR looses power.
13. If the serial port is used, open the Serial Port tab. Select the desired baud rate from the
pull down menu (1200 to 38400 bits per second). This value should normally be less
than the over-the-air data rate indicated in the Link Configuration field. Select the
desired character length, parity and number of Stop bits from the pull-down menus.
The receive (from user device) and transmit (from the ATR) data can also be inverted by
the ATR by checking the associated Data Invert boxes.
14. The serial port uses a transparent mode of operation and operates as follows:
When user data is detected on the serial port, the ATR collects all bits
received into a packet of up to M bytes (configurable max packet size).
Multiple packets may be required to capture the entire message, if longer
than the configured max size.
When the port goes idle for N (configurable) character times, the packet
is transmitted over the wireless link
This feature allows the ATR to be transparent to the serial port protocol and uses data
port activity to determine when to transmit. This mode will support most serial port
SCADA protocols
15. Click on SET to make the desired Serial Port changes within the Radio.
16. The ATR should now be configured and ready for installation and operation.
