4. I can ping SMN-890 but SMN-890 seems not able to contact with

server. What should I do?

Try to ping the server IP to make sure the server is contactable in

network first.

If the server is able to ping, open the SMN-890 ‘server settings

configuration page’, make sure server IP address and port are set

correctly. If only one server is used, make sure the 4 server IP are

set to same value. For the changes of setting to take effect, click

‘save’ button then reboot the device by clicking the ‘reboot’ tab.

‘Figure 6 on page 13’ shows the ‘server settings configuration

page’.

If SMN-890 is still not able to contact with the server, check the

firewall settings of the server. Make sure the server port is not

blocked by firewall.

5. How to know if SMN-890 able to receive data from the sensor?

When SMN-890 receives data from sensor, the UHF Led will

blink. It is shown on ‘figure 2 on Page 6’. Besides, you can open

SMN-890 statistic web page. The SMN-890 will show how much

data has been received since it is power-on.

If SMN-890 cannot receive any data, make sure the SMN-890 RF

frequency is set correctly and there is a tag within its coverage

range.

6. Why SMN-890 Led keep blinking once it is power-up?

Once SMN-890 is power-up, its Led will keep blinking to indicate

SMN- 890 now is in boot loading stage. When it is boot loaded

successfully (after 10 seconds), the Led will stop blinking.

7. Why the Green Led on SMN-890 front side keeps blinking?

The blinking of this green led indicates SMN-890 is transmitting

IR signal. The blinking frequency indicates the SMN-890 IR

transmitting frequency. As thus, the green led will not blink if

SMN-890 IR transmission is disabled.
