END OF THE TEST
After pressing the [ENC5] STOP, the test will be finished.
28 mLAN I/F (50pin)
* Only use in the company
50 CPU (DRAM/EEPROM) ALL
The all read/write test of the DRAM and the EEPROM is per-
formed. Check that OK is displayed.
RESULT OF THE TEST
OK :
NG :
read error of DRAM
NG :
refresh error of DRAM
NG :
read error of EEPROM
END OF THE TEST
After displaying the result, the test will be finished.
51 WAVE MEMORY ALL
The all read/write test of the WAVE RAM (the DRAM for wave
form stuck the circuit board) is performed. Check that OK is dis-
played.
RESULT OF THE TEST
OK :
NG :
END OF THE TEST
After displaying the result, the test will be finished.
52 SIMM ALL
The all read/write test of the WAVE MEMORY (SIMM) is per-
formed. Check that OK is displayed.
RESULT OF THE TEST
OK :
516, 517, 518, 519: CN number
In case of OK
**
: the capacity (MByte) of the understanding
DRAM
In case of R/W error
**
: NG
NG :
In case of the SWP30 access error
END OF THE TEST
After displaying the result, the test will be finished.
After pressing the [ENC5] STOP, the test will be finished.
53 DRIVE 100MB VERIFY (SCSI)
Connect the HDD to the SCSI Bus and execute the read/write test of
the 100MB. Execute by pressing the [ENC5] MANUAL and check
that OK is displayed.
The SCSI ID of the drive can be selected by testing on the [ENC3].
(The default ID is the ID4.)
The data on the SCSI DRIVE may be destroyed, so execute this test
after saving the back-up data.
RESULT OF THE TEST
OK :
n : SCSI ID(0 - 7)
