Digital I/O Expansion Card Installation Instructions
PN 67601
Use the following procedure to install digital I/O
expansion cards in 920i indicators:
1. Disconnect indicator from power source.
Disconnect power before removing
indicator backplate.
2. Place indicator face-down on an antistatic
work mat. Remove screws that hold the
backplate to the enclosure body.
Use a wrist strap to ground yourself and
protect components from electrostatic
discharge (ESD) when working inside the
indicator enclosure.
3. Carefully align the large option card
connector with connector J5 or J6 on the CPU
board. Press down to seat the option card in
the CPU board connector.
4. Use the screws and lockwashers provided in
the option kit to secure the other end of the
option card to the threaded standoffs on the
CPU board (see Figure 1).
Figure 1. Installing Option Card Onto CPU Board
5. Make connections to the option card as
required. Figure 2 shows connections
available on connector J3 (up to eight digital
I/O channels). Connector J2 provides all 24
channels using a 50-pin ribbon cable (see
Table 3).
Use cable ties to secure loose cables inside the
enclosure.Once cabling is complete, position
the backplate over the enclosure and reinstall
the backplate screws. Use the torque pattern
shown in Figure 4 to prevent distorting the
backplate gasket. Torque screws to 15 in-lb
(1.7 N-m).

2920i Digital I/O Expansion Card Installation Instructions
6. Ensure no excess cable is left inside the
enclosure and tighten cord grips.
7. Reconnect power to the indicator.
8. Use the DIG I/O menu to configure digital I/O
as necessary. See the 920i Installation Manual,
PN 67887.
Figure 4. 920i Enclosure Backplate
The 920i automatically recognizes all installed option
cards when the unit is powered on. No hardware-specific
configuration is required to identify the newly-installed
card to the system.
A digital I/O expansion card installed at connector J5
on the CPU board is configured as slot 1; a card
installed at connector J6 is configured as slot 2.
