2 520/720i/820i/920i DeviceNet Installation and Programming Manual
2.0 Installation
The DeviceNet Interface hardware consists of a
dual-board option card. DeviceNet-specific functions
are provided by a DeviceNet module, which is
factory-installed onto a bus adapter card. The bus
adapter card plugs into an open option card slot on the
520 , 820i , or 920i CPU board (or expansion board)
and provides power and access from the indicator bus
to the DeviceNet module.
This section describes the procedures used to install
the DeviceNet Interface into the
520 , 820i , and 920i
indicators, connect communications cables, and set
the baud rate and node address DIP switch on the
DeviceNet module.
2.1 Installing the DeviceNet Interface
Use the following procedure to install the DeviceNet
Interface into
520 , 820i , and 920i indicators.
2.1.1 Installing DeviceNet Option in the 720i, 820i or
920i
Use the following procedure to install the DeviceNet
Interface in the
720i , 820i or 920i indicator:
1. Disconnect indicator from power source.
Disconnect power before removing indicator
backplate.
The 820i and 920i have no on/off switch.
Before opening the unit, ensure the power
cord is disconnected from the power outlet.
2. Open indicator enclosure. For indicator models
with backplates, 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 connector (J1) on the
bus adapter card with connector J6 on the 820i ,
J12 on the 720i , or J5 or J6 on the 920i CPU
board. Press down to seat the bus adapter 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 Figures 2-1 and 2-2).
5. Wire the card to the network as described in
Section 2.2 on page 4.
6. Set DIP switch as described in Section 2.3 on
page 4.
7. Use cable ties to secure loose cables inside the
enclosure.

8. For indicator models that include a backplate,
position the backplate over the enclosure and
reinstall the backplate screws. For the
820i or
920i desktop and universal models, use the
torque pattern shown in Figure 2-3 to prevent
distorting the backplate gasket. Torque screws
to 15 in-lb (1.7 N-m).
