4.1 Operating mode
Operation mode of EH-ETH is set by a dip switch on the front panel. The set operation mode is effective after
completion of EH-ETH initialization. There are 2 ways to start the initialization, one is from turning on power
and another is from executing Hardware and software reset.
Out view of the dip switch is shown in Fig. 4.1.1.
Regarding detailed Ethernet information setting refer to "5.2 Ethernet setting". And regarding detailed "self
diagnostic refer to "10.1 Test functions".

*1: In case of setting lowest byte of IP address, OFF position of the switch means "0" and ON position means
"1".
Upper 3 bytes are fixed to "192.168.0". Therefore select one IP address temporally from "192. 168.0.1 to
192.168.0.63"
*2: "*" means don't care.
*3: Need loop back connector.
Caution
- Because IP "192.168.0.0" has a special meaning, all bit 3 to 8 should not be "0". If the bit 3 to 8 are all "0",
then LED's turn ON or flick as follows.
In case of SOFTWARE VER.00 to VER.02: The Status LED turns ON in red 6 times.
In case of SOFTWARE after VER.03: The Status LED tuns ON in red 7 times and the I.ERR LED
- IP address set by the dip switch is used temporally to access a Web server in side EH-ETH.
Therefore the IP address set by the dip switch is not saved in a FLASH ROM inside EH-ETH.
