Protocols • 522
Name Description Default Port
Control To send commands to control the
sensor. 8190
Data To retrieve measurement output. 8190
Health To retrieve specific health indicator

Ethernet Ports for ASCII
Channels can share the same port or operate on individual ports. The following port numbers are
reserved for Gocator internal use: 2016, 2017, 2018, and 2019. Each port can accept multiple
connections, up to a total of 16 connections for all ports.
Serial Communication
Over serial, Gocator ASCII communication uses the following connection settings:
Parameter Value
Start Bits 1
Stop Bits 1
Parity None
Data Bits 8
Baud Rate (b/s) 115200
Format ASCII
Delimiter CR
Serial Connection Settings for
ASCII
Up to 16 users can connect to the sensor for ASCII interfacing at a time. Any additional connections will
remove the oldest connected user.
Polling Operation Commands (Ethernet Only)
On the Ethernet output, the Data channel can operate asynchronously or by polling.
Under asynchronous operation, measurement results are automatically sent on the Data channel when
the sensor is in the running state and results become available. The result is sent on all connected data
channels.
Under polling operation, a client can:
l
Switch to a different job.
l
Align, run, and trigger sensors.
l
Receive sensor states, health indicators, stamps, and measurement results
Gocator sends Control, Data, and Health messages over separate channels. The Control channel is used
for commands such as starting and stopping the sensor, loading jobs, and performing alignment (see
Command Channel on the next page).
