Aviosys 9211 - Manual (Page 13)

If the resistance between the two contacts in one set within 0Ω~200Ω, 9211 shows ON. If the
resistance within 500Ω~
∞, 9211 shows OFF. So user can detect the movement of equipment through
the magnetic reed switch or other kind of reactive sensors.
NOTE :
1. The data in this figure is the average measure
value. To ensure the correct detection, we suggest
user set the voltage lower than 200Ω when it shows
ON and higher than 500Ω when it shows OFF.
2. When measure the resistance of web contacts, the
maximum voltage is 5V and the maximum currency is
no more than 10Am.
PS: magnetic reed switch: using the magnetic field of the magnet to produce a signal when there is a
movement happened in switch. Low cost and easy to use is the chief characteristic of magnetic reed
switch. Most of them are used in security equipment, living product and automatic mechanism.
4.3 Connecting to the Internet:
After the Ethernet and router have been set correctly, you can access the IP Power 9222 from the
Internet. It will provide all kinds of convenience.
To correctly setup the device
:
1.) Assign the right IP addresses and make sure that you can connect to your 9222 via local network.
2.) If a router/firewall is used, the router must be port mapped or port forwarded to the port of the
9222. Please refer to your routers manual in the port forwarding section.
After these steps have been correctly setup, you should be able to access the device through the
internet without any problems.
Below is a picture of what the setting may look like.
