04 - external EEPROM checksum error. This means that the data in the external EEPROM
could be corrupted or the checksum value itself could be wrong. If several
reprogramming attempts do not eliminate this error, then the external EEPROM must
be replaced. Applicable to COPE only.
08 - blank internal EEPROM. This means that the internal EEPROM is blank (all locations
contain the hexadecimal value FF). Reprogram the radio. If unsuccessful, replace the
related microprocessor. Applicable to COPE only.
10 - ROM checksum error. This means that the read-only-memory (ROM) of the related
microprocessor has an error. Replace the faulty microprocessor. Applicable to COPE
only.
20 - Hardware error. This means that the external EEPROM is faulty. Replace the external
EEPROM and reprogram the radio. Applicable to COPE only.
The above listing contains the basic errors that can be displayed to the user. However, if more
than one error occurs simultaneously, the error message is simply an addition of the values of the
errors involved. A few examples will clarify this. Note that since the error values are
hexadecimal, the addition will also result in hexadecimal values. Some examples of common
error messages are given below.
Error message examples:
ERR 0 X1 - The CORE µP has an internal EEPROM checksum error. (X may be any value)
ERR 1 01 - The COPE µP has an internal EEPROM checksum error.
ERR 1 03 - The COPE µP has an internal EEPROM checksum error as well as a RAM
read/write error.
ERR 1 0B - The COPE µP has a RAM read/write error as well as a blank internal EEPROM
and internal checksum error. (01 + 02 + 08 = 0B in hexadecimal).
ERR 1 24 - There is an external EEPROM and hardware error as well as an external
EEPROM checksum error.
ERR 1 30 - The COPE µP has a ROM checksum error and the external EEPROM has a
hardware error. (10 + 20 = 30 in hexadecimal.)
ERR 1 00 - The radio has no errors.
ERR 1 0D - The display that comes up for a COPE 5 radio when the programmer starts writ-
ing to the radio.
