-== Description: ==
+== Software Features ==
 The PBX-USB is a USB interfaced CNC controller that was developed specifically to work with the CNC USB Motion Controller Software from [http://www.planet-cnc.com www.planet-cnc.com]. This Interface sports 4x 10 pin PBX-Header Connections for interfacing to our existing stepper motor drivers. It has an additional header for direct connection to our RBX-1 3 channel relay board. This software/hardware combination can be further expanded with jog key inputs and an I2C bus for nearly unlimited additional I/O. This will allow the development of jog pendants, digital readouts, and input/output cards for a variety of purposes. The software runs on Windows and replaces Mach3 or EMC2. It can even be run through a virtual machine on a Mac or Linux host.

-|Pie
+|Connect a 10K logarithmic taper potentiometer to control jog speed. This signal is replicated in the pendant header (SPEED).
 |-
-|E-stop Loop
+| align="right" | E-stop Loop
 |The E-stop loop is a normally closed circuit which loops through the 16-pin pendant header and the e-stop loop screw terminals. Any open condition in the loop will cause an e-stop. If e-stop switch(es) are not used, the circuit must be closed with jumpers. A small peice of wire will suffice to close the screw terminal loop.
 |-
-|Jog Inputs
+| align="right" | Jog Inputs
 |The jog inputs can be used to make a simple jog pendant. Normally open push buttons connected to the jog inputs and the adjacent +5V connections will do the trick.
 |-
-|Limit/Home Inputs
+| align="right" | Limit/Home Inputs
 |Normally closed limit/home switch loops. You can use a single input for both + and - switches, or separate switch inputs for + & -. The LZ- input is used for the tool length compensation touch plate.
 |-
-|Aux Outputs
+| align="right" | Aux Outputs
 |The spindle, mist, and flood outputs come out to the relay board header for direct connection to our RBX-1 relay board. Those signals are also replicated to the screw terminals for connection to other devices. The signal output cannot exceed 20mA or the micro-controller will be damaged.
 |-
-|I2C
+| align="right" | I2C
 |Currently the I2C interface suports Spindle (M3, M4, M5), Coolant (M7, M8, M9), general purpose outputs (M62, M63, M64, M65), as well as current machine position.
