Digital Outputs

 

 

The MCT466-QC provides a choice of serial output formats, RS232, RS485 and USB.  RS232 
is suitable for a single NIR tester to computer connection over a distance of up to 100 feet (30 
meters).  USB is optional and used for direct connection to a laptop PC. 
 

 

Serial Requirements: 

 

RS232/485:

    

Baud Rate: 9600 to 38400 (9600 default) 

 

               

Parity: None 

 

                

Data Bits: 8 

 

                

Stop Bits: 1 

 

Cables: 

 

 

RS 232: 9 pin ‘D’ serial cable wired pin to pin 
RS 485: Shielded twisted pair.
