4. Configuring the AC4486
4.1 EEPROM P
A Host can program various parameters that are stored in EEPROM and become active after a power-
on reset. Table 7 - EEPROM Parameters, gives the locations and descriptions of the parameters that
can be read or written by a Host. Factory default values are also shown. Do not write to any EEPROM
addresses other than those listed below. Do not copy a transceiver’s EEPROM data to another
transceiver. Doing so may cause the transceiver to malfunction.

40 bytes - Product identifier string. Includes
revision information for software and hardware.
This value should only be changed when
recommended by Aerocomm.
This byte specifies the maximum amount of time
a transceiver will report In Range without having
heard a beacon (equal to hop period * value).
Do not set to 0h.
For systems using the RS-485 interface or Parity
Mode, the serial stop bit might come too early
(especially at slower interface baud rates). Stop
Bit Delay controls the width of the last bit before
the stop bit occurs.
FFh = Disable Stop Bit Delay (12us)
00h = (256 * 1.6us) + 12us
1 – FEh = (value * 1.6us) + 12us
Set 0 = 38h (Europe 500mW) – AC4486-5/500
