The 2801–JMB interface board is designed for direct edge connection to the
I/O Interface Box, Catalog Nos. 2801–N21, –N27.
If you intend to use the 2801–JMB board and the I/O Interface Box, you will
need to know the relationship between the discrete I/O line numbers and the
LED numbers, the optic–isolator type, and the terminal block screws
numbers on the 2801–JMB board. These are shown in the figure and table
that follows.
To power the JMB logic components, you must connect an
external +5VDC power supply to the (+) and (–) terminal
screws shown on the board layout that follows.
