User’s Manual
SUs must use the same channel, either automatically negotiated or set in
common.
• Network Name: a 32-bit (entered as 4 hex digits) network key that must be
the same for all communicating radios.
• AES Private Key: a 128-bit (entered as 32 hex digits) value that is the private
encryptionkeyusedtosecurethetrafcsentbetweenradios.Allcommuni-
cating radios must have the same assigned key.
• Serial Port Settings: the familiar parameters associated with any UART con-
nection, baud rate, data bits, parity and stop bits.
• Bit Delay and Record Length: These are performance tuning parameters that
help to optimize the match between incoming data and packet transmission
in UART mode. For a complete discussion, go to avalanwireless.com/faqs.com
and look for AW2400mSPI Performance Tuning.

10. At this point, you will want to activate the second Evaluation Board by repeat-
ing steps 1 through 9 with it. If both Evaluation Boards are connected to the
same PC, the COM port numbers assigned will be different. The higher num-
beredCOMportineachpairisalwaystheBootCongSerialPortandthelower
numbered port is used for data that is transmitted and received via RF.

are successfully communicating: Their channel LEDs will show the same binary
channel number and the quality LEDs will indicate RF signal strength. If a radio
is continuously scanning through the RF channels and just one red quality light
is lit, the units have not successfully negotiated an RF connection and a mis-
