27.2. Introduction
The base unit uses a 32K bit serial EEPROM (IC4) for storing volatile parameters. All parameters
are set up before the base leaves the factory. Some of these are vital for the operation of the
hardware so a set of default parameters is programmed before the actual hardware fine-tuning
can be initiated. This document lists all default settings with a short description.
In the tables below values in a range that are similar are not repeated; i.e. Address 00 to 01
contains the value 00 simply means that the value 00 is repeated in all addresses in the range. All
values in this document are in hexadecimal notation.
Type Name Description
D default The EEPROM location is preset to the Default value by the eeprom default
loader.
A adjust
The EEPROM location is set during the production test and should not be
overwritten. The value is set by the eeprom default loader only if the
location
contains all 1’s (byte: 0xFF, word FFFFh), i, e. it has never been set.
- EEPROM location which is not set at all.
