1.8.10 EEP-ROMS
(1) EEP-ROMS and stored data
AG-DV2500 is equipped with two EEP-ROMS for the purpose of data stored, and their contents are as per the following list. When
the circuit board or EEP-ROM is replaced, there will be no data in the EEP-ROM. When the unit is powered up, and the SYSCON
CPU or MSD CPU recognizes that there is no data in the EEP-ROM, it automatically writes initial data into the EEP-ROM to initialize
it. The memory data shown in Table 1.8.10 will all be reset back to default settings, so it will be necessary to perform necess ary
adjustments and settings again.
(2) IEEE1394 ID setting method
IEEE1394 equipped units have an ID, as defined by the IEEE1394 standard, stored in the internal EEP-ROM (IC 301). At the time of
production, the ID assigned for each individual unit are written into the EEP-ROM, and a sticker bearing the ID is affixed inside the
unit. When the EEP-ROM (DV/CPU board assembly) or DV/CPU board assembly is replaced, the ID needs to be set again.
Procedure for setting IEEE1394 ID
The ID is an 8 digit, hexadecimal code, with 1 high Byte being the model code, and 3 low Bytes being individual to the unit. The
model code is automatically initialized, so only the lower 3 Bytes of individual code need to be set manually. Go from Service Menu
OTHERS Menu MEM. EDIT (Memory Edit) to select the address in the ID data section and make the setting directly. The 3
low Byte address is as follows. Make the setting while confirming the ID printed on the label (ID: 80xxxxxx) pasted on the inside of
the AG-DV2500 (See Fig. 1.8.10).
