Here is the information you need to wire it to a second parallel port: http://cnc4pc.com/Tech_Docs/guide_fo..._over_LPT2.htm. You can use the supplied brains.
Please note you should wire the e-stop button to relay that will disable your system, as you should not leave mach3 alone to disable to shut down your system, as it the cause of the need for e-stop could be a problem related to the PC control. You could use our C22 – Pendant Interface Board: http://www.cnc4pc.com/Store/osc/prod...roducts_id=159, which comes with this relay. This wiring sample shows more information on how it is done: http://cnc4pc.com/Tech_Docs/E-STOP_RELAY.pdf. That is why all our breakout boards come with a terminal that allows the system to be disabled at hardware level.
Please also note there are also other ways of commenting this pendant to Mach3:
1. Modbus: Please we offer a Modbus system with 64 I/Os, of which 16 can be analogs. : http://www.cnc4pc.com/Store/osc/index.php?cPath=39. Check the M13 : http://www.cnc4pc.com/Store/osc/prod...roducts_id=184. Gives you the following features:
a. Comes with a DB25 connector for connecting the pendant.
b. Has a relay that reflects the status of e-stop, which can be used to disable your system at hardware level on e-stop.
c. Has lots of additional I/Os, this board is very practical for configuring advanced control panels with lots of buttons, knobs and lights. Many users when retrofitting, just fit the board in the existing control box, wire all the buttons and knobs to the board, and just run a serial cable back to the PC.
d. You can use the plugin for easy configuring the pendant (and other stuff connected to the M13 board): http://www.cnc4pc.com/Store/osc/prod...roducts_id=209.
2. PoKeys: We offer a mother board and a Pokeys core board: http://www.cnc4pc.com/Store/osc/index.php?cPath=54. If using the M2 Mother Board: . You will have the following benefits:
a. Has a DB25 connector for connecting the pendant.
b. The M2 has a relay that reflects the status of e-stop button, which allows handling e-stop at hardware level.
c. You can use the supplied brains and instructions.
d. You can use lots of additional expansion boards, including keypads, LCD displays, and lots boards with additional features. There are several other boards in the works.
e. Configuring and programming it is fairly easy using mach3 brains.
f. Plugins to empower the user with new features are in the works.
