Revision G USER’S GUIDE

DR915L Repeater Address Map:

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

0x0002 = Preamble Bytes (high byte) (Valid range = 16 - 1000. Default = 16. A value of less than 16 will cause

improper operation.)

0x0003 = Preamble Bytes (low byte)

0x0004 = Group 1 (Valid range = 0 - 255)

0x0005 = Group 2 (Valid range = 0 - 255)

0x0006 = Baud Rate (*see below for proper settings)

0x0007 = Debug Enable (Valid range = 1 is enabled, 0 is disabled.)

DR915LT Address Map:

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

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

0x0003 = Preamble Bytes (high byte) (Valid range = 16 - 1000. Default = 16. A value of less than 16 will cause

improper operation.)

0x0004 = Preamble Bytes (low byte))

0x0005 = Destination Group (Valid range = 0 - 255 where 0 is broadcast group)

0x0006 = Destination Address (Valid range = 0 - 255 where 0 is broadcast address)

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

0x0008 = Source Address (Valid range = 1 - 255. A value of 0 must not be used.)

0x0009 = Packet Length (Valid range = 1 - 177. Default = 177.)

0x000A = CTS Deassert Limit (Valid range = 1 - 178. Default = 178. This value should be greater than the CTS

Assert Limit.)

0x000B = CTS Assert Limit (Valid range = 1 - 177. Default = 89. This value should be less than the CTS Deassert

Limit.)

0x000C = Baud Rate (*see below for proper settings)

0x000D = Communications Port (Valid range = 0 is SPI port, 1 is UART)

0x000E = Number of Repeaters in System (Valid range = 0 - 255.)
