Connecting Communications
The wiring and connections of the communications interfaces are described
here. For further details, refer to the following manuals.
Serial communications: E5ZE Multipoint Temperature Controller Communica-
tions Manual (H77)
DeviceNet communications: E5ZE-8 Multipoint Temperature Controller Devi-
ceNet Communications Manual (H104)
2-7-1 RS-232C
•
Mount the RS-232C Communications Unit on the E5ZE Serial Communica-
tions Model.
•
The E5ZE is connected to the RS-232C interface in the ratio of 1:1.
•
Refer to the E5ZE Multipoint Temperature Controller Communications Manual
(H77) for details on communications.
Cable Connections
•
The maximum cable length is15 m. To extend the transmission path, use the
OMRON Z3RN RS-232C Optical Interface.
•
Use shielded twisted-pair cable with a wire thickness of AWG28 minimum.
•
Use the following OMRON 25-pin D-sub Connectors or equivalent.
Plug:
XM2A-2501 Connector
Hood:
XM2S-2511 Hood

•
The E5ZE’s RS-232C communications do not support a CD (carrier detect)
signal from the host device. If the CD signal is required, provide support at the
host device.
When using the RS-232C auxiliary setting jack on the E5ZE-8
D1
B
(DeviceNet Model with casing), use the following Connecting Cables.
•
ES100-CT021-202 (25-pin)
This Cable is used to connect the E5ZD-SDL1 Setting Display Unit.
•
ES100-CT023-202 (9-pin)
The RS-232C auxiliary setting jack is designed to be used only temporarily for
initial settings and performing maintenance. Do not use the RS-232C auxiliary
setting jack to mount the E5ZE to a device. If the RS-232C auxiliary setting jack
is left connected for a long time, the reliability of the connection will deteriorate.
