Physical Connections for Installed Boards
The indicator enclosure must be opened to connect cables and set DIP switches for the Remote I/O interface.
Ensure power to the indicator is disconnected, then place the indicator face-down on an antistatic work mat.
Remove the screws that hold the backplate to the enclosure body, then lift the backplate away from the enclosure
and set it aside.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD)
when working inside the indicator enclosure.
The Remote I/O interface board (see Figure 2-1) is mounted on brackets above the indicator CPU board.
Connections between the two boards are as follows:
•
Ribbon cable from connector J15 on the indicator CPU/power supply board (see Figure 2-5 on page 5) to
connector J1 on the Remote I/O board.
•
Serial communications wiring from the indicator EDP port on connector J4 to connector J4 on the
Remote I/O board.
Once wiring and DIP switch configuration (see Section 2.3) are complete, position the backplate over the
indicator enclosure and reinstall the backplate screws. Use the torque pattern shown in Figure 2-3 on page 3 to
prevent distorting the backplate gasket. Torque screws to 10 in-lb (1.13 N-m).
