Thank you for purchasing the CX1000.
This manual contains simple explanations about how to install and connect
the CX1000. For more information about the procedures described herein,
safety precautions, and the CX1000 functions and operation, please refer to
the PDF manual found on the provided CD-ROM.
Installation Procedure
1. Cut the instrument panel according to the diagram below.
For the panel cut dimensions when installing multiple units closely
together, see the
the provided CD-ROM.

2. Insert the CX1000 into the front of the panel.
3. Using the mounting brackets that came with the package, attach the
CX1000 to the panel as shown in the following figure.
First, attach the two mounting brackets and temporarily fasten the
attachment screws. Next, fix the CX1000 in place by tightening the
attachment screws with the appropriate torque (0.7 to 0.9 N-m.). As you
fasten the screws, press the mounting bracket against the case so that
they are in contact with each other.

There are various terminals and connectors on the rear panel of the CX1000. Connecting them to peripheral devices allows you to perform control and measurement operations. Below are the names of each connector and terminal, as
well as connection procedures.
Connecting the Ethernet Interface
• When only Connecting to a Hub
Connect the CX1000 and the PC through a HUB as shown in the
Connecting the Serial Interface
• RS-232 (When Connecting to a Computer or Other Such Devices)
Verify that the CX1000 has an RS-232 connector, and then connect a serial cable to it. Connect the other end of the serial cable to the other device.

The following figure illustrates an example in which the CX1000 and
a PC are connected to the network. When connecting the CX1000 or
the PC to a preexisting network items such as the transfer rate and
connector type must match. For details, consult your system or
network administrator.

Label on the Front of the Terminal Cover
The terminal numbers are written on the label on the front of the terminal cover. Terminal numbers are
unique three-digit numbers. They are used to locate terminals on the wiring diagram, etc. The highest
digit indicates the arrangement position of the terminal block; the lower two digits indicate the terminal
position within the terminal block (top right terminal is assigned "01" bottom left terminal is assigned
"36"). The terminals that cannot be used are indicated as " ".
Label on the Back of the Terminal Cover
Indicates the type of input/output signals for each terminal.
You can select the control modes from "single loop control", "cascade control", and "loop control with
PV switching" on the CX. The arrangement of the analog control input (PV) terminals are changed
depending on the control mode selected. The terminal arrangement for these three control modes are
written on the label on Analog Control Input Terminal.
