Connection
Connection port
There is no power supply to
the EJ1.
Supply power from the EDU power
supply terminal.
The Programmable Terminal
connection is incorrect.
Refer to the Programmable Terminal,
RS-422A Converter, and EJ1 manu-
als and wire the connection correctly.
The SAP is not compatible
with the EJ1.
Use a SAP for the EJ1.
The SAP is not for direct con-
nection.
Use a SAP for direct Programmable
Terminal connection.
The RS-422A switch settings
are incorrect.
Refer to the product manual and
make the correct switch setting for
the communications conditions.
An E58-CIFQ1 USB-Serial
Conversion Cable is con-
nected to port A and the CX-
Thermo Support Software is
started.
The CX-Thermo Support Software
and Programmable Terminals cannot
be used at the same time.
Close the CX-Thermo Support Soft-
ware if using Programmable Termi-
nals.
To temporarily use the CX-Thermo
Support Software, either turn OFF
the Programmable Terminal or move
the Programmable Terminal to the
System Screen and stop Program-
mable Terminal communications.
The Programmable Terminal
communications conditions
are different from the EJ1
communications settings.
Move the Programmable Terminal to
the System Screen and set the com-
munications destination for the com-
munications port on the
Communications Setting Screen to
Temperature Controller and the baud
rate to 38.4 (kbps).
