DR915LT Address Map:

0x0001 = Channel (Valid range = 0 - 63)

0x0002 = Tx Holdoff (Valid range = 5 - 255. Default = 5.)

0x0003 = Preamble Bytes (Valid range = 15 - 255. Default = 15. A value of less than

15 will cause improper operation.)

0x0004 = Destination Group (Valid range = 0 - 255 where 0 is broadcast group)

0x0005 = Destination Address (Valid range = 0 - 255 where 0 is broadcast address)

0x0006 = Source Group (Valid range = 1 - 255. A value of 0 must not be used.)

0x0007 = Source Address (Valid range = 1 - 255. A value of 0 must not be used.)

0x0008 = Packet Length (Valid range = 1 - 180. Default = 180.)

0x0009 = CTS Deassert Limit (Valid range = 1 - 180. Default = 180. This value should

be greater than the CTS Assert Limit.)

0x000A = CTS Assert Limit (Valid range = 1 - 180. Default = 150. This value should

be less than the CTS Deassert Limit.)

0x000B = Baud Rate (*see below for proper settings)

0x000C = Communications Port (Valid range = 0 is SPI port, 1 is UART)

0x000D = Number of Repeaters in System (Valid range = 0 - 255.)

0x0100 = ESN byte #1 (least significant byte)

0x0200 = ESN byte #2

0x0300 = ESN byte #3

0x0400 = ESN byte #4 (most significant byte)
