*Note: DC-to-DC Converter Built In (-V) Option)
Notes:
1. If the “-V” Option is selected for this module (standard):
With this option an onboard DC-DC Converter will generate approximately +25V Vo internally.
With this option DO NOT CONNECT ANY EXTERNAL VOLTAGE TO THE VEE PIN.
2.
If the “-TC” option is selected for this module:
The contrast voltage is generated and preset internally, and it it temperature compensated.
With this option leave both the Vo and Vee pins with NO CONNECTION.
