This jumper is used to connect the current-loop output

 

 

(XTR117). For voltage output modules, set this jumper to the

 

 

Vdut Power (5V connected to power) position. For current-loop

 

 

modules, set this jumper to the Loop Power (power to loop

 

 

supply) position.

 

 

 

JMP9

NC

This jumper connects the VOUT pin on the PGA309 to the

 

 

XTR117 input. For voltage output modules, set this jumper to the

 

 

NC (no connect) position. For current-loop modules, set this

 

 

jumper to the Vout to XTR position.
