Use jog shuttle & SELECT to set the pattern MOSI (CH2) or MISO (CH3) to be
assigned to Pattern B.
13.
Use jog shuttle & SELECT to set the data length of the determination pattern to
be specified from 1 to 8 bytes (Data Byte box). The number of bytes displayed
in the B Pattern box is set to the number of bytes that matches the selected
result.
14.
Use jog shuttle & SELECT to set the determination pattern for each byte in
hexadecimal or binary (B Pattern box). When determination is not to be
performed, select X.
15.
Use jog shuttle & SELECT to set the condition of Pattern B to True or False
(Condition box).
16.
Use jog shuttle & SELECT to select whether to compare the Pattern B to the
pattern immediately after the byte count (First Byte) or continue to compare until
SS is negated (Anywhere) (After Byte Count box).
Select this when using
pattern B as a trigger
condition.
Select the data length
of Pattern B in the
range of 1 to 8 bytes.
