4-3-22 Overall check
(1)
The overall check is the final error rate test to be applied to MTU
for which various checks and adjustments have been made. This test
can be made on the user system side, if test program, etc. is
available there.
Description is given below on the overall check procedure using SOB
(D/CAS interface) and SOD (SCSI interface).
As for the MTU of BASIC interface, the interface signal can be
checked by using SOE. however, the SOE has not the error rate test
function. As for the MTU of BASIC interface, execute the overall
check by using the user system.
Articles to be used
(a) Work tape

"D/CAS" SOB
(c) "SCSI" SOD
(d) DC power supply
"D/CAS"
(2) Check procedure
(a) Connect SOB in accordance with Item 4-2-6.
(b) Load the work tape on MTU.
(c) Key in "BE", B2". and "A4". The tape is rewound up to BOT, and
the indicator DRY on SOB lights up.
(d) Key in "D51", and "AB". The MTU starts the write error test.
(e) After the completion of the write error test, the transfer block
count is indicated in hexadecimal notation to the display of SOB.
Record this value.
(This data is necessary to check if the
transfer block count matches when read error test is made by using
