Programmable Input Lines
To connect I/O devices to one or more programmable input lines, first connect an I/O
extension cable (part number 300-0240), and optionally a DB-25 extension cable
(185-0334) and terminal block (195-0330), to the frame grabber’s P4 and/or P6
connector. Use Table 9 to determine the pins to use on the 300-0240 cable’s DB-25
connector or on the 195-0330 terminal block.
Opto-isolated inputs on P4 and P6 share the anode (+) pin between two lines. See
Programmable Line Input Circuitry on page 73 for a wiring diagram for this connection
type.
