Answer
When registration of the device (e-RDS) is deleted from the
UGW, the status will be changed to that the communication
test has not completed because related
information has lost from a database. Therefore, device
information will also become invalid if that condition is going
for seven days without carrying out the communication
test. Hence, to avoid the invalid condition, carry out the
communication test.
The following cases can be considered in the becoming NG
case.
- 1. Name resolution was failed due to an incorrect host name
or DNS server has been halted.
- 2. Network cable is blocked off. Network cable is broken.
- 3. Proxy server settings are not correct.
The schedule of data transmitting, and the start time are
determined by settings in the UGW side. The timing is once
per 16 hours by default, and counter data size
could be maximum 1400 bytes.
While operating the device (e-RDS), the power of the device
must be ON. If power OFF is needed, do not leave the device
power OFF for long time. It will
become "Device is busy, try later" errors if the power supply
of network equipment such as HUB is made prolonged OFF.
