NEEDED I N EIGHT-BIT MOPE.
2. PlNS 1 THRU
8
AND A THRU J CAN BE USED AS
EITHER BIDIRECTIONAL OR UNIDIRECTIONAL
LINES BETWEEN THE 10746A BINARY INTERFACE
AND THE SYSTEM CONTROLLER.
I F USED AS
BIDIRECTIONAL LINES, KEEP I N MIND THAT I T IS
HALF-DUPLEX OPERATION (I.E., YOU MUST SEND
OR RECEIVE SEPARATELY). ALSO, PlNS 9 THRU
16 AND K THRU T NEED NOT BE CONNECTED.
I P USED AS UNIDIRECTIONAL LINES, THEN PlNS
1 THRU 8 AND A THRU J ARE THE OUTPUTS TO
THE SYSTEM CONTROLLER AND PlNS 9 THRU 16
AND K THRU T ARE THE INPUTS FROM THE
SYSTEM CONTROLLER. REFER TO TABLE C-2
