• Name resolution was failed due to an incorrect host name or DNS server has been halted.
• Network cable is blocked off.
• Proxy server settings is not correct.

Q: When does E-RDS send counter information to UGW? How many data is sent?

Ans.

The schedule of data transmitting, the start time are determined by settings in the UGW side. The send time cannot be
specified on the E-RDS side. Data is sent once every 16 hours.
The data size of counter information is approx. 285 KB.

Q: Will data which failed to be sent due to an error in communication with UGW be resent?

Ans.

Data shown below will be resent.

• Jam log
• Service call log
• Alarm log
• Browser information

It is resent only when the web browser option is enabled.

Data is resent endlessly (after 5, 10, 15, 20, 25, and 30 minutes since the occurrence of communication error; once 30
minutes have passed, it is resent at 30-minute intervals) until it is sent successfully. Resend continues even if the power is
turned OFF and then ON.

Q: What is the upper limit of the number of COM-LOGs? What is the upper limit of the number of
characters of error information displayed in a COM-LOG?

Ans.

Up to 5 log data can be saved.
