Connect the Frame Ground Wire
1. Connect a frame ground wire to the I/O module's Frame Ground
terminal.
2. Connect the other end of the frame ground wire to frame ground.
Caution: The shield ground connections of the RS-232 port, LAN port, PoE
port, I/O port and Frame Ground terminal are internally connected. The
system grounding is designed to be at a zero ground potential; this zero
ground potential extends through the cable and to peripheral equipment (e.g.,
a vision system, PLC, etc.). To ensure safe operating conditions, it is strongly
recommended that all ground connections are checked to ensure that a zero
ground potential is met.

Connect the Input and Output Wires
If connecting the vision system to an I/O device, complete the following steps.
Note: Refer to the In-Sight
discrete input and output lines.
1. Determine how I/O devices will be connected to the I/O module's input
and output terminals.
2. Use a screw driver to loosen the appropriate screw terminals.
3. Connect the input and output wires (16 - 22 AWG, solid or stranded wire)
to the input and output terminals and the other end of the cables to the
applicable I/O device.
4. Tighten the screw terminals with the screwdriver to secure the wire leads
in the terminal block; the maximum torque is 0.1921 Nm (1.7 in-lb).
