Safety Notes:
The control board is DC powerelectronics of the designed to accept
ONLY. Ensure connections are made that the positive and negative
correctly ing the unit. Incorrect wiring will cause before the power on
damage to the board.
The control board is o not conductive an open circuit design. D allow
objects like small or metal pieces of wire stray pieces of to touch any of
part of the circuit Mount inside an inclosure using insulated (plastic) .
stand offs or insulating pads. Do not mount directly to any conductive
metal or aluminum plates. Handle with care, do not drop or touch the
electronic parts on the board.
Keep the board from damp environment.
Keep the board in adequate ventilation.
Keep the board from mechanical damage.
Note: the DB25M-3R6A has a male 25 pin line printer port input to be
used with a female parallel printer cable. It can not be used with serial
printer cables, usb to serial printer cord adapters, or any other cable that
is not a parallel printer cable . If your computer does not come with a
DB25 parallel printer port, one may be installed. To avoid frustration be
sure you have the right cable.
Note: then DB25M-3R6A is equipped with a usb port. This port is for
supplying power to the board. It is not used for any communication with
the computer or with the board. It is strictly used as a power supply
input.
Usage:
The control board is designed for MACH3 software DB25M-3R6A CNC
and other CNC programs that utilizes the s DB25 er port. computer line print

The control board is extensively used in the CNC uch as CNC industry. S
engraving machine CNC lathes CNC lasma cutting machine CNC s p s, , ,
laser engraving machine CNC milling machines s , , etc.
The use of the DB25M-3R6A is designed to put an isolation buffer
between the computers sensitive electronics and the high current and
voltages of the control (motor) drivers. The board also aids in making easy
connections of the line printer port and to help boost signal strength.
Features:
1. igh reliability Easy to install, low cost, h .
2. Absolute voltage isolation The CNC control board is powered by the .
computer USB port used as digital power that d s and is a supply is esigned
as common cathode and common an ode which is connected to n , the
motor d iver's common portr .
Note: This must be energized to operate the control board.
3 designed into the . Three relays are board that can be programmed to
control external equipment such as solenoid valve cooling pump and so a ,
on. is A secondary power supply (24VDC) required to energize the three
relays, all inputs and spindle-out on the board. This is the used as analog
power power supply and is isolated from the digital supply through the use
of an optocoupler. Each relay has a corresponding LED to as a use pilot
lamp.
Note: this power source is not required if the relays, inputs and spindle are
not intended for use.
4 for . Five signal ports are isolated by optocouplers which can be used
limit position finding origin points, starting and switches, switches,
emergency stopping.
5 (6 Axis . Twelve output ports can control six motors simultaneously
control). T can also be programmed to be used as single outputs hey .
Some ports are communally designed for two functions (input or output)

Due to the limitations of the Db25 LPT, there are only 12 outputs.
Pin 1, Pin 14, Pin 16, and Pin17 are shared outputs. Which means you select
how to use them. You can have up to 6 driver outputs. However in doing so,
you will have no relay outputs or spindle output. By using the onboard jumper
you select which outputs you wish to use and how to use them. If you wish
to use all three relays and spindle, you will only have 4 axis output.
P14 Jumper, P16 Jumper, P17 Jumper.
Remove these jumpers to disable the relays.
Once disabled they can be used as a motor
out pins.
P1 Jumper. Remove this jumper to
disable the spindle output. Once
disabled they can be used as a motor
out pin.
