Remote I/O Installation and Programming Manual
2.0 Installation
The section describes the procedures used to install
the Remote I/O interface board into IQ plus 510/710
indicators, connect communications cables, select the
termination resistance, and set the configuration DIP
switches for the Remote I/O interface.
2.1 Installing the Remote I/O Interface
To install the Remote I/O Interface board into the IQ
plus 510/710 indicators, do the following:
2.1.1 Replace Backplate
1. 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.
Loosen cord grips 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.
2. Disconnect and remove any load cell, serial
communications, and digital I/O cabling
through the indicator backplate.
3. Disconnect power cord ground wire from
enclosure ground stud, then disconnect
ground wire from backplate. Cut cable tie that
secures the line filter input wires to the inside
of the indicator enclosure and remove power
cord.
4. Remove cord grips from original backplate
and reinstall in Remote I/O backplate.
5. Route power cord, load cell, digital I/O, and
communications cables through cord grips in
Remote I/O backplate.
6. Reconnect power cord wires to the line filter.
Use a cable tie to secure the line filter wires to
the cable tie mount. Reconnect backplate and
power cord ground wires to enclosure ground
stud.
7. Reconnect load cell, digital I/O, and
communications cables to the appropriate
connectors on the indicator CPU board.
2.1.2 Install Remote I/O Interface Board
8. Use the four 6-32NC kep nuts supplied to
mount the three brackets as shown in
Figure 2-4 on page 4.
9. Attach three cable tie mounts to the inside of
the indicator enclosure as shown in
Figure 2-4.
10. Use cable ties to secure cable from the
backplate LED annunciators to the Remote
I/O Interface board.Allow enough slack in the
wires to reach the location of connector J3
(see Figure 2-4).
11. Remove connector J4 from the header on the
indicator CPU board. Connect the black, red,
and green wires to the connector as shown in
Table 2-1 and in Figure 2-4, then reinstall J4
on the indicator board.
12. Plug 10-pin ribbon cable into connector J15
on the indicator CPU board as shown in
Figure 2-4. Ensure connector is oriented as
shown in the drawing, with red wire of ribbon
cable toward center of board.
13. Use the four 6-32NC x 1/4 machine screws
supplied to mount the Remote I/O Interface
board on the brackets as shown in Figure 2-4.
2.1.3 Connect Cables to Remote I/O Interface
14. Connect black, red, and green wires from the
indicator J4 serial connector to the J4
connector on the Remote I/O Interface board.
Table 2-1. Indicator-to-Remote I/O Serial Port Pin
Assignments
15. Plug ribbon cable connector from J15 on the
indicator CPU board into connector J1 on the
Remote I/O Interface board. Ensure cable is
oriented as shown in Figure 2-4, with red wire
of ribbon cable attached at pin 1 on both
connectors.
