DIL Switch Settings 

The DIL switch located on the top site of the unit provides 
customer-specific settings of desired operation modes. 

 

The switch settings below show normal operating mode with 
current input and freely adjustable frequency range. No default 
values will be loaded, the serial link is set to RS232 format and 
to printer transmission mode.
