Digital I/O Expansion Card Installation Instructions
PN 67601
Use the following procedure to install digital I/O
expansion cards in 720i, 820i, and 920i indicators:
1. Disconnect indicator from power source.
Disconnect power
indicator backplate.
before
Use the torque pattern shown in the indicator
Installation Manual to prevent distorting the
backplate gasket. Torque screws to 15 in-lb
(1.7 N-m).
removing
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 920i
CPU board, J6 on the 820i CPU board, or J12
on the 720i CPU board. Press down to seat the
option card in the CPU board connector.
4. Use the screws and lock washers 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).

5. Make connections to the option card as
required. Figure 2 shows connections
available on option card connector J3 (up to
eight digital I/O channels). Connector J2
provides all 24 channels using a 50-pin ribbon
cable (see Table 1).
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.

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), 820i Installation Manual (PN
93018), or 720i Installation Manual (PN
103121) for more information.
The indicator 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.
For the 920i, 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.
A digital I/O card installed in the 720i or 820i is
configured as slot 2.
