•When Connecting to a Preexisting Network
The following figure illustrates an example in which the CX2000 and
a PC are connected to the network. When connecting the CX2000 or
the PC to a preexisting network such things as the transfer rate and
connector type must match. For details, consult your system or
network administrator.

Connecting a Monitor to the VGA Output Terminal
(Option /D5)
Supported monitors: VGA monitors and multisync monitors with VGA
display capability.
1. Turn off the CX2000 and the monitor.
2. Connect the CX2000 and the monitor using an analog RGB cable (D-
Sub connector).
3. Turn on the CX2000 and the monitor. The screen of the CX2000 is
displayed on the monitor.
CX2000 Installation and
Connection Guide
IM 04L31A01-71E 4th Edition
Yokogawa Electric Corporation
Thank you for purchasing the CX2000.
This manual contains simple explanations about how to install and connect
the CX2000. For more information about the procedures described herein,
safety precautions, and the CX2000 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.

2. Insert the CX2000 into the front of the panel.
3. Using the mounting brackets, attach the CX2000 to the panel as shown
in the following figure.
First, attach the two mounting brackets and temporarily fasten the
attachment screws. Next, fix the CX2000 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.
(The figure shows the case when
the mounting brackets are used
on the top and bottom of the case.)

found on the provided CD-ROM.
Connection Types and Procedures
There are various terminals and connectors on the rear panel of the CX2000. 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.

•RS-422/485 (When Connecting to a PLC, Temperature Controller or
Other Such Devices)
Verify that the CX2000 has an RS-422/485 connector, and then connect the crimp
connectors (for 4-mm screws) to the terminal strip as illustrated on the right. Do not
expose more than 5 cm of the cable surface from the shield.
Connecting the Power Supply
When using electrical wiring, be certain to follow the safety
recommendations prescribed in the CX2000 User's Manual.
Use a power supply that meets the following conditions:
Rated supply voltage: 100 to 240 VAC
Supply voltage range used: 90 to 132, 180 to 264 VAC
Rated supply voltage frequency: 50/60 Hz
Permitted supply voltage frequency range:
50/60 Hz ±2%
Maximum power consumption: 75 VA (100 V), 106 VA (240 V)
1. Turn OFF the CX2000 and open the cover (transparent) for the
power supply wires.
2. Connect the power cord and the protective ground cord to the power
supply terminals.

3. Close the cover (transparent) for the power supply wires and secure
it in place with screws.
For the power supply specifications and connection method of the 24VDC/AC
power supply option, please refer to the CX2000 User's Manual.

Connecting Input/Output Connectors
When connecting various input/output connectors for control or
measurement, proceed as described below.
Connect the crimp connectors (for 4-mm screws) to the terminal
strip.
1. Turn off the CX2000 and remove the terminal cover.
2. Wire the signal wires to the terminals.
Attach the terminal cover and secure it with the screws.
