4 Auto Streaming Control
The MINI-ARRAY Basic Two-Piece Measuring Light Curtain by default has an auto streaming feature. Auto stream
automatically starts streaming data 5 seconds after the device is powered up without the need for a command.
The default measurements that are streamed are First Beam Blocked (FBB) and Total Beams Blocked (TBB). Up to four
measurements can be streamed, which can be configured using Banner's Sensor Configuration Software.
If any serial command is sent within the initial 5 seconds, streaming is disabled. To resume streaming, cycle power to the
device. After streaming begins, all communications to the sensor fail because of an unavoidable data collision.
BAUD Rate
Default setting: 38400
The default BAUD rate can be changed by using the Banner Sensor Configuration Software.
Auto Stream Serial Protocol
The serial communication follows the this data format:
1. Start of Header: 0xF4
2. Sensor Address: 0x41
3. Command: 0x64
4. Number of Data Bytes: 0x04 in little endian format (LSB first)
5. Data Bytes (4 total)
6. Checksum Low
7. Checksum High
Checksum Calculation
Ones compliment of the sum of the bytes in Auto Stream Serial Protocol, numbers 1 to 5.
Example All Channels Clear:
F4.41.64.04.00.00.00.00.62.FE
Example All Channels Blocked:
F4.41.64.04.01.00.20.00.41.FE
