EPC1200 SERIES OPERATION MANUAL
54/56
CON 2:
Printer mechanism connector. This is to connect the flat cable of the LTPA245B-384 Seiko
Printer mechanism.
CON 3:
Communications connector. Read sections
2.3-RS232 Serial Interface
and 2.4-
Centronics
Parallel Interface
for pin out and specifications. USB versions have the USB connector
located in the same position.
GROUND ANCHOR POINT:
This point is electrically connected to the main ground of the circuit
(and through a filter to GNDP). It can be used to connect to the
mechanism ground point to prevent paper from being charged with
electrostatic electricity.
F1:
Fuse wire, 10A. Apart from the supply connector polarity, the interface has a 10A, 29SWG
FUSE WIRE that protects it from inverse voltage as well as from current overload. In case of
needing a replacement, same fuse wire should be used, otherwise the interface could get
permanently damaged.
SW1:
Main switch. This switch is used for feeding paper, interface settings an printing Self-Test.
Please read section 3.2- Button Functions for more detailed information.
D3:
LED indicator. This is the position where the Tri-color LED indicator should be connected. The
polarity is as indicated on the silkscreen.
The output current capability (of each color) is about 10mA.
