The main objectives of these step-by-step instructions are:

• Power the Board and e-stop and test that the board activates/deactivates at hardware level only with e-stop.
• Install the C25XP license and configure the pinout and functions of MACH4 supported by the C25XP and test that MACH4 is communicating with the C25XP OK.
• Enable and configure the Safety Charge Pump to make sure the C25XP activates (green LED) when MACH4 becomes active (out of reset).

STEP 1: Connect an E-Stop button to short the E-Stop terminals, disable the Safety Change Pump (JUMPER=OFF). The SCHP is a watchdog, which will allow the board to activate only while the control software is active. This should activate the board (green LED). IF not, check other possible fault conditions and make sure they are not active. 

The main objectives of these step-by-step instructions are:

• Power the Board and e-stop and test that the board activates/deactivates at hardware level only with e-stop.
• Install the C25XP license and configure the pinout and functions of MACH4 supported by the C25XP and test that MACH3 is communicating with the C25XP OK.
• Enable and configure the Safety Charge Pump to make sure the C25XP activates (green LED) when MACH3 becomes active (out of reset).

STEP 1: Make sure the controller is connected to an Ethernet port on the PC and powered with LEDs ON.

STEP 2: Connect an E-Stop button to short the E-Stop terminals, disable the Safety Change

Initial Step by Step Wiring and Testing of a C94 with UCCNC

STEP 1: Connect an E-Stop button to short the E-Stop terminals. 

• This should give you a green LED while the board is powered and e-stop is closed.
• IF not, check other possible fault conditions and make sure they are not active.

STEP 2: Make sure the controller is connected to an Ethernet port on the PC and powered with LEDs ON. 

STEP 3: Download the UC Utility program for UCxxx.

• Run the to establish the connection, 
• Set a fixed IP on the PC’s LAN cad and whitelist t
