■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.

■ WIRING• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.

POINTS OF CAUTION■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

■ CONFORMITY WITH EU DIRECTIVES• The actual installation environments such as panel configurations, connected devices and connected wires may
affect the protection level of this unit when it is integrated in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure CE conformity.
■ POWER INPUT RATING & OPERATIONAL RANGE• Locate the power input rating marked on the product andconfirm its operational range as indicated below:

R7E-RS4CONFIRMING ETHERNET CONNECTION■ IP ADDRESSThe R7E does not support BootP Table Software. The IP Address and Subnet Mask can be configured using the R7CON
Configurator Software.
The Modbus/TCP Port No. is fixed at 502.
■ CHECK WIRING
Connect an Ethernet cable to the RJ-45 connector.
■ CHECK LED
When wiring is correct, LINK is turned on. When the module is connected in 100 Mbps, LINK100 is blinking.**. For firmware revision V0.20 or later, LINK100 is ON.

■ CHECK R7E CONNECTIONEnter “ping command” on the Windows MS-DOS as follows:		C:¥WINDOWS>ping ***.***.***.***		(***.***.***.***: Enter IP address in decimal.)		ping ***.***.***.*** with 32 bytes of data:		Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64		Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64		Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64		Reply from ***.***.***.*** : bytes=32 time<10ms TTL=64		Ping statistics for ***.***.***.***		Packets:Sent=4,Received=4,Lost=0(0% loss)
Replies in case of normal connection are as shown above. If the connection cannot be established normally due to e.g. wrong
IP address, other replies such as ‘timeout’ will be received.
■ CHECK CONNECTION TO THE APPLICATION SOFTWARECheck Point 1: LINK LEDs
When normal connection with PC, PLC or hub is established, the front LINK and LINK100 (when connected in 100 Mbps)
is/are turned on regardless of data sending/receiving status. Check power supply to the switch/hub in case that these LEDs
are not on.
Check Point 2: RUN Indicator LED
A green light turns on at the RUN Indicator LED in normal data sending/receiving with an application.
