April 1997 CG00000-011503 REV. A H-5
The tests can be set using the following parameters:
H-4.3.2 LOAD/UNLOAD: Two diagnostic tests to check loading and unloading
(Set the tests in detail using the given parameters.)
The tests can be set using the following parameters:
DIAG parameter 1: For “FRD READ”, “BWD READ” or “WRITE”, set the operation mode.
0x00 - STREAMING : Set a continuous read (or write) operation.
0x01 - START/STOP : Set the start/stop operation.
: For “LOCATE”, specify a sector. Specify a location sector from 1 to 99.
DIAG parameter 2: For “FWD READ”, “BWD READ”, “WRITE”, “FRD/BRD”, “L.W.R.” and “FEED
THR”, specify a test wrap.
0x00 - WRAP 1 : Wrap-1 test
0x01 - WRAP 2 : Wrap-2 test
DIAG parameter 4: For “WRITE”, select a write data pattern from the following:
0x00 - D.S.E. PT : D.S.E. pattern
0x01 - 2 F PT : 2F pattern
0x02 - 1/6 F PT : 1/6F pattern
0x03 - 1/5 F PT : 1/5F pattern
0x04 - 1/4 F PT : 1/4F pattern
0x05 - 1/3 F PT : 1/3F pattern
0x06 - 1/2 F PT : 1/2F pattern
0x07 - 1 F PT : 1F pattern
0x08 - 1/12 F PT : 1/12F pattern
0x09 - 1.5 F PT : 1.5F pattern
DIAG parameter 5: For “L.W.R.”, select a path of the Loop Write To Read command from the following:
0x00 - PATH:A : Path A
0x01 - PATH:B : Path B
DIAG parameter 6: For “L.W.R.”, set a level of the Loop Write To Read command from the following:
0x00 - LEVEL LO : Low level
0x01 - LEVEL HI : High level
execution time: When diag parameter 1 is START/STOP, set the GO ON time (time when the tape is
running).1 count is 10msec.
If this parameter is set to “0,” the GO ON time becomes 10 ms.
: For the path test, specifies start position by the machine reel counter.
stop time: When diag parameter 1 is START/STOP, set the GO OFF time (time when the tape is
not running). 1 count is 10msec.
If this parameter is set to “0,” the GO OFF time becomes 0 ms.
: For the path test, specifies end position by the machine reel counter.
execute count: Specify an execution count. Specify a command execution count from 1 to 99,999.
When 0 is set, the command execution continues with no stop.
1) NO CTG:Loader and Threader test not using cartridge ------- CMD CD : 0x20
2) WITH CTG:Loader and Threader test using cartridge. ------- CMD CD : 0x21
DIAG parameter 2: For NO CTG, select a test type from the following:
0x00 - LOADER : Loader test
0x01 - THREADER : Threader test.
DIAG parameter 3: For WITH CTG, select a loading position from the following:
