4.5.1 IP SETTINGS
When the SMC motion sensor is connected to the LAN the motion sensor will receive a dynamic IP
address from the DHCP in the network if the Dynamic IP radio button is selected in the SMC
configuration software.
Note that the motion sensor is only searching for the DHCP server during the boot up process.
The motion sensor IP address is user configurable from the SMC Configuration Software. A radio
button option to enter a static IP address is available.
If the ethernet connection does not have a DHCP in the network, as for example when connecting
the motion sensor directly with a crossed ethernet cable to a PC the IP addresses would have to be
entered manually in the SMC IMU Configuration software. The motion sensor does not require to
enter a subnet mask.
If a static IP is set for the motion sensor and the selected IP address is no longer available, the motion
sensor would have to be setup using the serial communication to enter a new IP address within the
network alternatively set the motion sensor to acquire a new dynamic IP if there is an available DHCP
server in the LAN.
The IMU IP address displayed in the configuration software when connected to the network is the IP
address that the motion sensor is currently using. It can be the last IP address acquired via DHCP or
an IP that has been set manually. If the option to use a dynamic IP address is used the motion sensor
may get a different IP Address by the DHCP server during the next startup.
Note: Care must be taken when setting a static IP address, that the IP address chosen, does not
conflict with another device on the network. The motion sensor will start broadcasting on the
selected IP address even if there is another device with the same IP address in the network. The SMC
motion sensor will not respond to ARP requests such as a ping.
