3.2.4. Rack 4: THRSHOUT
This board allows the current thresholds for an analogue input channel to be read or written by the
application. The application can write new thresholds in the THRSHOUT board for a particular channel,
and it can read the current thresholds from the THRSHIN board, under control of a channel in the
THRSHOUT board.
Note that channels 0 and 41 are internal reference channels, and are not connected to the field.
Channels 1 to 40 are field channels.
Channel Description
1 Write the threshold data for a particular
input channel on channels 3 to 11 to the
module. The data is written on a rising
edge 0 to 1.
2 Read the threshold data for a particular
channel from the module to the THRSHIN
board. The data is read on a rising edge 0
to 1.
3 Channel number to write/read threshold
data. Range 0 to 41.
4 States 2 > 1 falling threshold
5 States 1 > 2 rising threshold
6 States 3 > 2 falling threshold
7 States 2 > 3 rising threshold
8 States 4 > 3 falling threshold
9 States 3 > 4 rising threshold
10 States 5 > 4 falling threshold
11 States 4 > 5 rising threshold
