Operating Mode - Hitachi EH-150 Applications Manual

4.1

Operating mode

Operation mode of EH-ETH2 is set by a dip switch on the front panel. The mode change is effective after
completion of EH-ETH2 initialization. The dip switch setting is effective only when power on or the reset
button pressed.
Regarding detailed Ethernet parameters setting, refer to "5.2 Configuration of Ethernet parameters using
EH-ETH2 Configurator". And regarding detailed Utility mode refer to "10.2 Send / Receive test facility".

[ Temporally IP address for Configuration mode]
Via the Ethernet, make Communication parameters setting by EH-ETH2 Configurator. So, require setting
temporally IP address to connect to EH-ETH2 Configurator. 3-top octet of temporally IP address is fixed value
"192.168.0". By dip switches No.4 to 8, set lowest octet of temporally IP address. "192.168.0.0"(No.4 to 8 are all
off) is invalid. Therefore, the range of assignable temporally IP address is from "192.168.0.1" to "192.168.0.31".

Caution
- Because IP address "192.168.0.0" has a special meaning, dip switches No.4 to 8 should not be all off. If the No.4 to 8
are all off, then the STS LED blinks 4 times cycle and the IER LED turns ON at the same time.
- IP address set by the dip switch is used temporally to access EH-ETH2 Configurator.
Therefore the IP address set by the dip switch is not saved in a FLASH ROM in EH-ETH2.
- When you change operation mode during normal operation, the all communications will be stopped. Regarding the
operation mode change and reset switch operation, please consult a system manager.
- When you restart EH-ETH2, you may operate relation equipments such as PC and work station.

Ethernet parameters are set by the user program.
Communication parameters (Ethernet parameters and ASR
parameters) are set by dedicated software "EH-ETH2 Configurator".
In this case, dip switches No.4 to 8 are the last 5 bits of temporally
IP address to connect to "EH-ETH2 Configurator".
