INTRODUCTION
This is a description how to customize MRS3000's EEPROMs.
The EEPROMs can easily be reprogrammed from the CU, by entering any of the programming modes.
EEPROM structure
The EEPROM is split in some different areas:
•
Area 1, local in each CU 200/210, determining it's identity number for the internal communication, it's
local short-numbers, and line attenuation. Remaining areas are common for all CUs:
•
Area 2 with tables specifying some general options, radio interface etc.
•
Area 3 with tables specifying the tone system, transmitter tables, receiver sequence's general
structure etc.
•
Area 4 with the call number-tables, specifying all individual call numbers to receive.
Each EEPROM area has it's own checksum.
If there is a checksum error in any EEPROM area, the connected CUs will not operate in the normal
way, their display will show: "EEPROM ERROR: code X".
To fix the error, the programming mode shall be entered, the set-up should be checked, or default
values restored, and programming mode exited again.
The programming areas for the different error codes are:
Error
code Area
1 & 2
2
3
3
4
4
PROGRAMMING
Programming of area 1 will not affect any other part of the system than the CU being programmed, to
which the LP will consider the connection as broken. As soon as programming mode is left, connection
will be established again.
Programming of area 2-4 will bring the whole system, all CUs and the LP, down. No regular traffic will
be handled as long as programming is going on. When programming mode is left, connection will be
established with the CUs, and the system will start operating normally.
Programming mode is entered by pressing the upper leftmost key once or twice to get the display
"PASSWORD:", enter actual password and programming mode is entered. For programming of area 4,
please refer to the
MRS3000 RECEIVER CALL NUMBERS PROGRAMMING GUIDE
.
For area 1-3 there are EEPROM default values residing in PROM. To restore the default values, press
the |TFR|-key and dial the additional password described below.
