Figure A-2. Serial Communication Options
Figure A-2 shows that the binary transmission has three independent options.
These options are independently selected and are used to custom-configure the
serial data format. The Suppress Clear Data option is applicable when the sensor
is unobstructed. While the sensor is blocked, serial data is transmitted; once the
sensor is unobstructed, the “clear” data is transmitted once, and then no further data
transmission occurs until the sensor is again blocked. The Suppress Header option
will serially transmit the array data bytes. The three header bytes are not transmitted.
The Compress Data option affects the data bytes for the measurement modes
excluding the ALL mode. Except for the ALL mode, the analysis modes use two bytes
to transmit the appropriate information. For cases where the sensor cannot provide a
result greater than 255, the Compress Data option will provide this data in one byte.
As an example, assume that you have a 48-channel sensor with a last beam blocked
of 35 and a controller ID of “B.” Assume two binary format options. The first option is
the standard Binary Transmission format. The second format will use the Suppress
Header and Compress Data options. The two strings would be as follows:
Option 1: Binary Transmission
0x1c B 0x00 0x23 0x0a (a total of 5 bytes per scan)
Option 2: Binary Transmission, Suppress Header, Compress Data
0x23 (1 byte per scan)
