The board connector is a 40 pin right angle connector termi-
nating to either a 37 pin D-subminiature assembly (option
B-2) a 40 pin connector with a 60-inch cable (option B-5),
or a 40 pin connector with a 24" cable (option B-9 used with
a Wall Mount Model) The B-5 option provides flexibility of
terminating BCD signal lines to the terminal board options
B-6 and B-7.
•
The pin designations for the BCD output are noted in Cable
Pinouts List - Parallel BCD Board Connector to BCD Con-
nector. All data outputs have a drive capability of 15 LSTTL
loads (6 mA total) and use positive true logic. PRINT/
READY has a drive capability of 10 LSTTL loads (4mA).
This option board is electrically and optically isolated from
the main board.
