1.  Check the interface parameters for both interfaces (on circulator and PC) 

and make sure they match. 
(Serial interface refer to page 45) 

2.  In the menu > MENU  CONFIG < set the menu item > REMOTE < to 

 > ON < .  

3.  Connect both units with an interface cable.. 
 

 

Like all parameters which can be entered through the keypad, interface 

parameters are stored in memory even after the circulator is turned off.
