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

HRSHOUT 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
