TEST

Operation 3-16
SYNC <0|1|2|3|4|5|6|7|8>
The commands SYNC <0|1|2|3|4|5|6|7> connect the selected
SYNC output to the corresponding TTLTRG line. SYNC 8
disconnects the SYNC output from the TTLTRG lines and is the
default (power up) state.
TEST 0.<testnumber> where <testnumber>::=1|2|3
This command causes the Option 01 to carry out a self test. The
possible tests are:
Non-Destructive RAM Test
EPROM Checksum Test
Non-Destructive Non-Volatile Memory Test
IF non-vol memory initialization is required, use the
TEST 0.3 command to accomplish the initialization.
Non-vol initialization will only be accomplished in the
event of a firmware revision change, or if corruption
of the non-vol is detected. If these conditions have
not occurred, the TEST 0.3 command will be executed
without reinitializing the non-vol memory. If non-vol
memory initialization is required, the contents od the
non-vol are invalid and will be erased during
initialization.
On commencing a test, the Ready bit of the status byte is reset
until the test is completed.
If self-test passes, the 1260-01 will return a hexadecimal 7F. If it
fails, an SRQ is generated, and the operator must send a YERR
command to determine the actual error.
