Fenix EPC1800 Operation Manual page 12

NOTES:
(1) If the number of dots that are energized at the same time is increased, a higher current
will flow; therefore, a power supply with an adequate current capability must be used.
(2) When designing lines and bit images, take the printing ratio and print duty into
consideration. Print quality may be poor if the printing ratio (energizing pulses/dot line) or
print duty is high.
(3) Average energizing pulse width is defined as 64 of 192 dots/dot line that are energized.
NOTE ABOUT POWER SUPPLY:
The current demand depends on the density of the printout. A 60W power supply covers all
adverse possibility (see section 3.6- ELECTRICAL SPECIFICATIONS).
FENIX offers different power supplies as an accessory option (See APPENDIX B – HOW TO
ORDER). These power supplies which have been exhaustively tested are available in OPEN FRAME or
ENCLOSED version.
4.3- RS-232 SERIAL INTERFACE
4.3.1- RS-232 Serial interface specifications
• Data transmission type:
• Synchronization:
• Flow control:
• Signal levels (RS232):
• Speed:
• Data length:
• Parity:
• Stop bits:
• Connector (user side):
NOTE: Speed and parity depend on the settings (refer to section 4.3.1- RS-232 Serial interface
specifications).
4.3.2- Change between online and offline mode
The printer is in offline mode:
1) When powering up or resetting the printer, until the printer is ready to receive data.
2) When the door is opened.
3) After pressing the button while the paper advances.
4) When 'out of paper' causes the printer to stop printing.
5) When the power supply has a temporal abnormal voltage change.
6) When an error has occurred.
4.3.3- Serial RS-232 interface pins assignment
The assignments of the terminals of the RS-232 connector and the functions of its signals are
described in the following figures:
WARNING: Beware not to invert the polarity of power supply. This may
irremediably damage the printer. Ensure that the voltage is the correct
one. Use the 4 terminals (4 wires) with 0.35mm² minimum section each.
