Discovery Commands
Sensors ship with the following default network configuration:
Setting Default
DHCP 0 (disabled)
IP Address 192.168.1.10
Subnet Mask 255.255.255.0
Gateway 0.0.0.0 (disabled)
Use the Get Address and Set Address commands to modify a sensor's network configuration. These
commands are UDP broadcast messages:
Destination Address Destination Port
255.255.255.255 3220
When a sensor accepts a discovery command, it will send a UDP broadcast response:
Destination Address Destination Port
255.255.255.255 Port of command sender.
The use of UDP broadcasts for discovery enables a client computer to locate a sensor when the senor
and client are configured for different subnets. All you need to know is the serial number of the sensor in
order to locate it on an IP network.
Get Address
The Get Address command is used to discover Gocator sensors across subnets.
