Programming Mode; Serial Rs-232 Connector - Fenix Imvico TK51 Series Operation Manual

FENIX IMVICO TK51/IF9000 OPERATION MANUAL
2.2.1.a) EARTH–GND connection.
The IF9000 arranges a terminal to connect the system EARTH to printer GND signal.
Between both terminals, there is a filter circuit implemented:
EARTH
R53
C3
1M
GND
This RC filter avoids a current drift when the EARTH circuit is not good (there is not
EARTH connection or is defective, other noisy device in the system is injecting spurious
in the main power supply, etc).
If the installation system EARTH is very good (impedance<5 Ohm), it will be possible to
have a direct and optimum EARTH-GND connection, by shorting C3 pads (it is not
mounted by default).
