In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
Note1:)
The LC876700 series can be mounted onto the circuit board of the LC 876500, LC876600 series.
In this case, the fluorescent character display tube power voltage (minus voltage) is supplied to the FIX0 pin. This would not cause any
error.
