To specify the output number to be adjusted, write the value to the rightmost byte
of IR word n as shown in the following diagram.
(Rightmost)
(Leftmost)
Word n
Output to be adjusted (1 to 8)
I/O specification
1: Output (fixed)
For the IR word addresses, n = 100 + 10 x unit number.
For Units #A to #F (10 to 15), n = 400 + 10 x (unit number – 10).
The following example uses output number 1 adjustment for illustration. (The
unit number is 0.)
