Alltrax Motor Controllers:   
Communications Software
The Programmable Alltrax Electric Motor Controllers such as the AXE
(Series wound motors) and the
DCX (Shunt wound motors) include an
RS232 communications port.  This port can be used to adjust user
settings such as throttle type, power settings, and speed settings.  It can
also be used to monitor operation of the controller real time.

The program runs on
Microsoft Windows(TM) based machines, laptops or
desktops using simple user friendly controls.  Alltrax provides this
software down-loadable free of charge (cables not included).  Controller
Pro software has not been run on MAC
(TM) based machines.

A kit can be purchased from Alltrax which includes:
  • Communications cable - RS232 to USB adapter
  • CD-R with Controller PRO operators manual, tech-notes, and the
    Controller PRO software program
  • Wall wart (120 VAC 60Hz transformer) supplies 15-20 VoltsDC to
    power the logic for programming.  (International 220VAC 50Hz
    input to 15-20 VoltsDC transformers also available)
  • Instruction Manual & Technical notes (Available from web site)
  • Free technical support
