Preliminary Rev.03
9.3 Error LED and measure
Following table shows the indication and the measure in case an error occurs in communication between
EH-ETH and other station.
9.3.1 ERR confirmation by LED indication
When EH-ETH detects the abnormality of devices itself and also the abnormality in a communication is
detected those LED that is related abnormally is lighted up.
No.
1 A fault of hardware
2 Setting of Ethernet information,
ASR information is wrong.
3 Temporary IP address is
192.168.0.0.
4 Cable wrong
5 A error occurs at the time
connection open (active open
station)
6 A error occurs at time of sending
7 A error occurs at time of receiving
*1: A connection specified passive station does not detect the abnormality below a data link level layer.
Therefore, the other station should have detection of error when the connection specified passive station
is not open.
The contents of this manual might be changed without notice.

Chapter 9 Maintenance, check, error
LED name Cause of error and measurement
STATUS Apply the power or reset with RES switch to initialize
I.ERR Correct the setting according to the contests of status
STATUS register or status register
Set IP address in the range from 192.168.0.1 to

POW (1). Wrong kind of cable
or
- Check if the using cable is straight or cross type.
Tx/Rx
(2). Wrong connection of cable
It confirms whether cable is inserted to a connector neatly
- It confirms whether cable is not snapping
ERR (1). The other station is not in network.
- Confirm that the other station is in network.
- Confirm the cables for own station and the other station.
(2). Setting mistake for own station
- Confirm the IP address and logical port number for the
own station.
(3). Setting mistake for the other station
- Confirm that the other station is in passive open.
Before the complete of the transmission procedure, EH-
ETH is required next transmission.
- Make cyclic transmission period longer.
- Make data size sending one time smaller.
Before the complete of the receive procedure, EH-ETH
receive next data..
- Make transmission priod of the other station longer.
- Make data size of receiving one time smaller.
