PPI-04 Parallel Port Interface

Table 1: 10-pin Header J3, J4, J5, J6 (see Figure 2)

The PPI-04 module is a buffered interface allowing direct connection of up to four single-axis step motor drivers to the parallel port of the personal computer. It can be used with BSD-01v2 or BSD-02 step motor drivers manufactured by Interinar. No separate power supply necessary. It is a perfect interface for all CNC applications where standard PC is used as a controlling device. The PPI-04 simplifies connection between computer and drivers eliminating soldering and mistakes made with custom cables.

The standard DB25 Male to Male Cable connects a PC to the PPI-04 module. This straight-thru cable must be fully-wired to support parallel application. Step Motor Drivers are connected to the PPI-04 module using 10-conductor ribbon cables with female receptacles on both sides matching 0.100"x 0.100" headers installed on BSD Drivers and PPI-04 Interface.

The power for internal circuitry is provided directly from the step motor driver through X-Axis connector J3. Only this header provides the power so when only one step motor driver will be used it must be connected to connector J3.
