Concepts
Discovery
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)
The Get Address and Set Address discovery commands can be used to modify a sensor’s network
configuration. Discovery 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.
Command Channels
A client can send commands and receive responses over the Control and Upgrade TCP channels.
Command Channels
Channel Port Description
Control 3190 Sensor accepts commands for most operations.
Upgrade 3192 Sensor accepts commands for firmware upgrades.
The Control and Upgrade channels can be connected simultaneously, but the sensor will accept only
a single connection on each port. If an additional connection is attempted on a port that is already
connected, the previous connection will be closed and the new connection will be accepted.
Result Channels
A client can receive data messages from a Gocator sensor by connecting to the Data or Health TCP
channels.
Result Channels
Channel Port Description
Data 3196 Sensor sends data messages.
Health 3194 Sensor sends health messages.
Each of the above ports can be connected simultaneously and the sensor will also accept multiple
connections on each port.
