OUTPUTS 
 
The two optocoupled general purpose outputs available on the CBX800 spring clamp terminal blocks are 
managed by the reader connected to the 25-pin connector. The meaning of the two outputs Output 1 and Output 
2 can be defined by the user. They are typically used either to signal the data collection result or, for 2D readers, 
to control an external lighting system.
