CNC4PC Pendant for Mach4 with C22M1

CNC4PC Pendant for Mach4 with C22M1

Used software: Mach4 4.2.0.4612, PLUGINS ESS V275

Used hardware: C82 R4 and C22M1 R1.

STEP 1: On many systems, MS Windows can recognize the USB drivers, but if not, you can download them from here: https://www.cnc4pc.com/pub/media/productattachments/files/Driver_FT232_USB_UART.zip

STEP 2: Connect the C22M1 to the USB port, Right Click on the USB Serial port, Select Update Driver Software.

STEP 3:

STEP 4:

STEP 5: Configure/Control/Plugins

STEP 6: Configure/Plugins/Modbus

STEP 7: CONFIGURING THE CONTROL SOFTWARE: To configure use the following sample configuration screen:

STEP 8: Add Modbus Function

STEP 9: To configure Encoder use the following sample configuration screen:

Mach4 configure

STEP 10 : Configure/Controller/Input Signal

STEP 11 : Configure/Controler/Output Signal

STEP 12 : Configure/Controler/MPGs

STEP 13 : You can download, install, and use this screen:
