Network: IP

WLAN

Enter the IP adress for the WLAN network interface. The IP adress shown right to the entry box shows the IP adress which is currently active. This is particular usefull if DHCP is switched on.

Enter the Subnet Mask / Gateway / DNS for the WLAN network interface. The values shown right to the entry box show which values are currently active. This is particular usefull if DHCP is active.

The Avisaro device has a build in DHCP clint and a DHCP server. The DHCP Server is mainly designed to make configuration easy - it is not a full featured DHCP server (such as keeping a list of all DHCP clients, ..). However, for i.e. sensor networks with Avisaro Moduls this works totally fine. Settings are:

Auto Configuration: In this setting, the DHCP server is only active, when the WLAN network name ("SSID") is "avisaro" and the WLAN network mode is "adhoc". Thus, during module setup the DHCP server is active and it is easier to connect using a PC since no IP setting needs to be configured manually. Once the Avisaro Modul is configured to another WLAN Network, the DHCP server is disabled automatically.

Autoconf. and Client: As long as the default wlan network name is active, the DHCP server is active, as soon as the WLAN network changed, the Avisaro DHCP Client is active and try to retrive its setting from the network.

Client only: Rather than using above static IP settings, a DHCP request is send out.

Server: The DHCP server is active. Clients (such as a PC or other Avisaro devices) requesting IP adresses are assigned settings. The DHCP Server is working on the IP addesses 192.168.0.* only. The start address is 192.168.0.150 and ranges until 192.168.0.254. 

Disabled: The DHCP Server and Client is switched off. Only static IP adresses are used

 

Local / Subnet Mask / Gateway / DNS

Enter the Local IP Adress / Subnet Mask / Gateway / DNS for the Ethernet network interface. The values shown right to the entry box show which values are currently active. This is particular usefull if DHCP is active.

Use DHCP

Disabled: The DHCP Client is switched off. Only static IP adresses are used.

Client: DHCP requests are send out to receive IP settings for the network.

TCP/IP Keep Alives

To verify that a TCP/IP connection is still alive if if no data is currently send, a 'Keep Alive' packet is send. This is basically a empty TCP packet which is acknowledged by the connection partner. If no acknowledge is received, the connection is terminated. All connected TCP sockets on all network interfaces will send keep-alive packets if they are inactive for the given time

Enter a value (in seconds) here to define how often a keep alive is send out. A '0' switches the feature off.
