1.0 Typical Wiring Schematic
A typical wiring schematic diagram is provided in Figure 1-1. Although it is designed for
UIM240xx Stepper Motor Driver, it may be used for other stepper motor drivers.
User control devices (such as PC) connect to the UIM2901-5A through a male to male DB25
cable. The logic side (user device side) electronics are powered by either a USB cable or a
standalone 5VDC power supply. A 12VDC power supply is required if the user wants to use
the Relay, Limit Switches, EMS Switch and/or other machine side electronics. There are opto-
isolators between the logic side and the machine side.
Please note, the 12V power supply is NOT requireded, if only the UIM240xx Stepper Motor
Drivers are connected (i.e., not using other switches or functions like spindle control, etc.).

2.0 I/O Definitions and Jumper Settings
To help users clearly understand the operation/configuration of the UIM2901-5A Breakout
Board, schematic drawings of the board are provided below. Please note, the jumpers’
orientation/direction is the same as that on the PCB.
2.1 DB25 Connector Schematic
UIM2901-5A uses a male to male DB25 cable to communicate with the MACH3 software.
The definition of each PIN is provided in the Figure 2-1. Al input signals are opto-isolated and
buffered. All Output signals are buffered and opto-isolated either by the UIM2901-5A Board or
by the UIM240xx Stepper Drivers.
If the upper two pins of JP1 is shorten, Axis X’ and Axis X running direction will be opposite. If
the lower two pins of JP1 is shorten,Axis X’ and Axis X running direction will be the same.

2.2 Motor and Charge Pump Control Circuit
By shorting the left two pins (near the mark of JP2/JP3) of both JP2 and JP3, MACH3’s
Charge Pump feature can be enabled. Charge Pump action will disable all UIM240 Stepper
Drivers and the Charge Pump relay, which can cause stepper motors and spindle to stop.
Shorting the right two pins of JP2 and JP3, the Charge Pump feature will be disabled. Signal
from the PIN17 can be used to control the open-collector output of P17C and P17E.

2.3 Digital Input and Output Circuit
By shorting the left two pins (near the legend of JP5/JP6) of both JP5 and JP6, the onboard
relay can be enabled and controlled through DB25 pin 17.
Pin 16 can be used as open-collector control output. Please note that, P16C links to the opto-
isolator’s collector pin and the P16E links to the emitter pin.

2.4 Spindle Control Circuit
By shorting the left two pins (near the legend of JP7/JP8) of both JP7 and JP8, a PWM wave
will be generated to provide a voltage used to control the spindle speed.


2.5 Digital Input Filters
By shorting the four sets pins of JP4, the hardware digital input filter can be enabled. If JP4 is
left open, the digital inputs can be used for high speed inputs.
