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.
