2 Remote I/O Installation and Programming Manual
2.0 Installation
This section describes the procedures used to install
the Remote I/O interface card into the
520 , 720i , 820i ,
and 920i indicators; connect communications cables;
select the termination resis tance; and se t the
configuration DIP switches for the Remote I/O
interface.
2.1 Installing the Remote I/O Interface
Use the following procedure to install the Remote I/O
Interface card into
520 , 720i , 820i , and 920i indicators.
1. Disconnect indicator from power source.
W arning
Disconnect power before removing indicator
backplate. The
520 , 720i , 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 and
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 option card connector with
the option card slot on the indicator CPU
board (or
920i expansion board). Press down
to seat the option card in the CPU board
connector.
4. Use the screws provided in the option kit to
secure the other end of the option card to the
threaded standoffs on the CPU board.
5. Set termination resistance (jumper JMP4) as
described in Section 2.1.1 on page 3.
6. Wire the card to the network as described in
Section 2.1.2 on page 3.
7. Set DIP switches as described in Section 2.2
on page 4.
8. Use cable ties to secure loose cables inside the
enclosure.
9. For indicator models that include a backplate,
position the backplate over the enclosure and
reinstall the backplate screws. For the
820i
and 920i desktop and universal models, use
the torque pattern shown in Figure 2-1 to
prevent distorting the backplate gasket.
Torque screws to 15 in-lb (1.7 N-m).
10. Ensure no excess cable is left inside the
enclosure and tighten cord grips.
