Control Boards Is Designed To Be Used To Control Our Thermal Printer
BD2-3880UC
Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.
Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.
Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.
Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.
Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.
Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.
After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.
Electronics Finder is a website of GID Industrial, an ISO 9001:2015-certified company that has specialized in servicing industrial computer boards and providing other industrial products for sectors including manufacturing, defense, aerospace, entertainment, healthcare, and more by utilizing our combined skills and vast international network of trusted suppliers since our founding in 2015.

CAUTION:
1. For LED of ERROR and PE, there is a resister of 330 Ω on the circuit side to make the
current value 10 mA. Please use LED with a forward voltage of approx. 2V. LED exceeding
10 mA may break a control board.
2. Power supply for circuit (VDD and GND) requires feeding to only one pin. However, power
supply for driver circuit (VP and P-GND) requires feeding to all pins to secure the capacity.
3. Serial interface equips a driver and receiver of RS-232C, make sure to use it at RS-232C
level.
4. RESET terminal is pulled up by 47 KΩ. Make sure to make this terminal NC, when this
terminal is not used.

5. POWER SUPPLY
5.1 Specifications
VDD : 5V ±5% Approx. 130 mA

Operating votage is 7.2V (Max)
8.5V is a voltage only right after charging. 8.5V cannot be used for
normal voltage.
5.2 Precautions
(1) Design the product to supply power to VDD before VP when power is supplied to this
control board.
(2) Design the product to turn off the power for VDD after VP when power is turned off.
(3) Make sure to turn off the power in case of connecting/disconnecting connectors.
(4) Make sure to use VDD and VP following their specifications.
(5) Make sure to use this control board connecting all of terminals between VP and P-GND.

Data input method : 8 bit parallel signal (DATA0~7)
Control signals : nACK, BUSY, nSTB, nFAULT, PE, nRESET
6.2 Explanation of Input/Output Signals
DATA0~7 : 8 bit parallel signal (Positive logic)
nSTB : Strobe signal to read 8 bit data (Negative logic)
nRESET : Signal to reset control board (Negative logic)
nACK : 8 bit data request signal. Pulse signal output at the end of the BUSY
signal (Negative logic)
BUSY : Signal to indicate BUSY state of the printer. Input new data for “LOW”
(Positive logic)
nFAULT : Signal which is made “LOW” when printer is in alarm state.
(Negative logic)
In this case all the control logics within the printer stop functioning.
PE : Signal which is output when paper runs out. (Positive logic)

BD2-3880/3890 User’s Manual
7.2 Explanation of Input/Output Signals
(1) RXD
Serial receiving data signal. On occurrence of framing error, overrun error, or parity error, the
data is printed as “?”.
(2) DTR
When this signal is READY, write data or a command. When they are written in BUSY, overrun
error is occurred and data is ignored. Data can be written into the input buffer even when the
printer is busy printing. A BUSY also occurs when the printer is powered on, in test print, in
Online mode, or being reset.
(3) TXD
If data remaining in the printer’s input buffer is 256 bytes or less, the printer transfers a DC3
(13H: Data Receive Not Ready) signal to the host. If data in the input buffer exceeds 256 bytes,
the printer transfers a DC1 (11H: Data Receive Ready) signal to the host.
(4) GND
Common GND on the circuit.
7.3 Error Detection
Parity, framing, and overrun are detected. On detection of any error, the data are stored in the
buffer as “?”.
(1) Framing Error
With “space” state having been detected on detection of a stop bit, error takes place.
The data are stored in the buffer as “?”.
(2) Parity Error
With an error having been detected under specifying parity check, the data is stored in the buffer
as “?”.
(3) Overrun Error
On detection of an overrun error, the data are stored in the buffer as “?”.
15
BD2-3880/3890 User’s Manual
7.4 Data Receiving Control
When DTR/DSR control is selected, data from the host is received with DTR signal at “space”
but not received with DTR signal at “Mark”. When XON/XOFF control is selected, data from
the host is received after sending XON but cannot be received after sending XOFF.
7.5 Buffering
Data transfer to the input buffer include DTR signals and TD signals as the control signals
concerned.
(1) DTR signals [See 7.2 (2)]
(2) TXD signals [See 7.2 (3)]
