WARNING
● Never handle the Control Board BD2-1220/1221 in the manners descried below;
otherwise, it may be damaged, get out of order or overheated, possibly causing smoke,
fire or electric shock.
● If the control board is damaged or breaks down, be sure to turn off the power, disconnect
the power plug from the wall outlet, and contact your CBM dealer.
• Do not allow the control board to be subjected to any strong impact or shock, such as stamping, hitting,
dropping, and the like.
• Install the control board in a well-ventilated place. Do not use the control board in such a manner that its
ventilation slots are blocked.
• Do not install the control board in a place like a laboratory where chemical reactions are expected, or in a
place where saltish gases are present in the atmosphere.
• Use the control board only on the specified voltage and frequency. Otherwise, fire or smoke generation may
occur.
• Do not connect/ disconnect the power cord or data cable by holding the cable.
Do not pull or carry the control board in such a manner that undesirable force is applied to the cables.
• Do not drop or insert any foreign substances, such as paper clips or pins, into the control board.
• Do not spill any liquid on or spray any chemical-containing liquid over the control board. If you spilled water
or any other liquid onto this product, immediately shut off power supply and contact your CBM dealer.
• Do not disassemble or modify the control board in any manner; otherwise, a fire or electric shock may result.
• Do not place the equipment where it can be easily touched during operation. Otherwise, possible shock or
static build-up may cause fire or damage to the control board electronics.
PRECAUTIONS FOR INSTALLATION
• Do not use or store the Control Board BD2-1220/1221 in a place exposed to heat of fire, moisture or direct
sunlight, or in a place where the prescribed operating temperature and humidity are not met, or in a place
exposed to oily mist, iron powder or dust; otherwise, the control board may get out of order, emit smoke or
catch fire.
• Do not install the control board in a place like a laboratory where chemical reactions are expected, or in a place
where saltish gases are present in the atmosphere; otherwise, there may occur a danger of fire or electric
shock.
• Install the control board on a horizontal, sturdy table in a place provided with proper ventilation and free from
any vibration. Do not install in an unstable place, as this may lead to equipment failure.
• Do not use the control board near a radio or television receiver. Avoid sharing an electrical outlet with a radio or
television receiver, or this may cause a reception problem.
• Never connect the grounding cable to a gas pipe, or this may lead to a danger of explosion.
• Be sure to turn off the power of the control board and the host computer connected before connecting or
disconnecting the cables; always hold both plug and cable. Do not use or wire the control board in such a
manner that an undesirable load is applied to the cables.
• Connect the connector cables correctly and securely.
• Use shielding wires or twist paired wires for signal lines in order to minimize the effects from noise. Do not
extend the data cable too long.
• Do not connect the data cable to noisy equipment.
• In case of emergency, always place the control board so that it is easily disconnected from the power source.
iv
PRECAUTIONS FOR HANDLING

• Exercise care not to drop any metallic foreign object onto this product.
• Do not spill any liquid on the control board, or spray it with any chemical-containing liquid.
• Do not stamp on, drop, hit, or impart any strong shock to the control board.
• Wirings to other devices should be carefully established to avoid cross connections which may damage not
only the control board itself, but other system devices attached to it.
• This product should only be used with the specified peripheral devices.
• Do not use the control board in a place where it can easily come into contact with the hands.
• This product contains devices that are sensitive to electrostatic damage. When handling, keep any source of
static electricity away from the control board.
• Do not connect this product to, or install it in the vicinity of, any equipment that is the source of
electromagnetic noise. The control board may have an adverse affect on any attached peripherals. We
recommend you use some kind of noise insulating device with this equipment.
• This product can be reconfigured for non-default operation parameters. When using a soldering iron for
jumper reconnections, exercise care not to damage the adjacent parts. Also be sure to turn off the control
board before launching reconfiguration work.
• When reshipping this product, carefully pack it to protect it from vibration, deformation, or electrostatic
damage possible in transit.
To prevent injuries and associated damages:
• Should any abnormal condition occur while the control board is operating, stop it immediately and
disconnect the power plug from the wall outlet.
• This product may partially heats up as a result of extended use. Allow a sufficient time to cool off before
starting repair or maintenance work.
• In case of trouble, never attempt to repair the control board yourself. Be sure to call your dealer for servicing.

2.3 Print Paper Specifications
Use the recommended thermal papers listed below:
TF50KS-E2D (normal paper) from Nippon Paper
F230AA (normal paper) from Mitsubishi Paper or equivalent
*Paper thickness depends on the thermal head models.
* If an unspecified thermal paper is used, print tone may vary from the standard print tone.
*To preserve printed information for extended time period, carefully control temperature, humidity,
and other storage conditions.
* For the details of usable thermal papers, refer to the Specifications for each thermal print head.
* While you can use up to 150µm of paper thickness on some print heads, it is limited to 80 µm if the
auto cutter (ACS-220/230 Series) is used.
2.4 Thermal Print Head and Peripheral Devices
The control board supports the following thermal print heads and peripheral devices:

3.1.2 Example of Power Connections
* For the serial and parallel interface connections, see the sections dedicated to the respective
interface.
CAUTION:
(1) The ERROR and PEOUT LED lights have a current limiting resistor of 330Ω each to limit driving current to 10 mA.
An LED with forward voltage drop under 2 V should thus be used for these lights. A driving current exceeding 10
mA could damage the control board electronics.
(2) The logic power supply (Vdd and GND) may have supply and return connections only to a single pin each.
However, the driver power supply (Vp and P-GND) must be connected to all the available pins in order to secure
the specified drive current capacity.
(3) As shown above, the LF-SW input connection is a circuit that uses a ceramic capacitor to prevent chattering. You
can adjust the switch if chattering is severe.
(4) The RESET input is pulled up to Vdd with an on-board 3.3KΩ resistor. Leave it at NC if it will not be used.
(5) The serial interface uses RS-232C driver and receiver. Be sure to use RS-232C compatible signal levels for this
interface.
(6) Unused terminals should be insulated to keep exposed cable leads from them.
