799 Decision 159
The byte mapping of each measurement/decision pair depends on its ID as specified in the
Gocator measurement interface. Each measurement will begin at byte (0 + 5*ID). For example,
a measurement with ID set to 4 can be read from bytes 20 (high byte) to 23 (low byte) and the
decision at 24.
ASCIIProtocol
This section describes the ASCII protocol.
The ASCIIprotocol is available over either serial output or Ethernet output. Over serial output,
communication is asynchronous (measurement results are automatically sent on the Data channel when
the sensor is in the running state and results become available). Over Ethernet, communication can be
asynchronous or can use polling. For more information on polling commands, see Polling Operation
Commands (Ethernet Only) on the next page.
The protocol communicates using ASCII strings. The output result format from the sensor is user-
configurable.
To use the ASCII protocol, it must be enabled and configured in the active job.
The Gocator 4.x firmware uses mm, mm
2
, mm
3
, and degrees as standard units. In all protocols,
values are scaled by 1000, as values in the protocols are represented as integers. This results in
effective units of mm/1000, mm
2
/1000, mm
3
/1000, and deg/1000 in the protocols.
For information on configuring the protocol with the Web interface (when using the protocol over
Ethernet), see Ethernet Output on page 434.
For information on configuring the protocol with the Web interface (when using the protocol over Serial),
see Serial Output on page 443.
Connection Settings
Ethernet Communication
With Ethernet ASCII output, you can set the connection port numbers of the three channels used for
communication (Control, Data, and Health):
