MPLAB ICE 4 In Circuit Emulator
User Guide

Install the Latest Software

Download the MPLAB X IDE software from www.microchip.com/mplabx and install onto your computer. The installer automatically loads the USB drivers. Launch MPLAB X IDE.

Connect to Target Device

Connect the MPLAB ICE 4 to the computer using
a USB cable.
Connect external power to the emulator. Connect external power* to the target board if not using emulator power.
Connect one end of the 40-pin debug cable into the emulator. Connect the other end to your target or optional adapter board.

Setup Wi-Fi or Ethernet

To configure MPLAB ICE 4 for Wi-Fi or Ethernet, go to Project Properties>Manage Network Tools in MPLAB X IDE.

Use the following steps to set up your selected computer connection.

Ethernet or Wi-Fi Setup and Tool Discovery in MPLAB X IDE

Connect the emulator to your PC via the USB cable.
Go to Tools> Manage Network Tools in MPLAB® X IDE.
Under “Network Capable Tools Plugged into USB”, select your emulator.
Under “Configure Default Connection Type for Selected Tool” select the radio button for the connection you want.
Ethernet (Wired/StaticIP): Input Static IP Address, Subnet Mask and Gateway.
Wi-Fi® STA: Input SSID, Security type and password, depending on the security type of your home/office router.
Click Update Connection Type.
Unplug the USB cable from your emulator unit.
The emulator will restart automatically and come up in the connection mode you selected. Then either:
All Except Wi-Fi AP: The LEDs will display for either a successful network connection or a network connection failure/error.
Wi-Fi AP: The normal Wi-Fi scanning process of Windows OS / macOS / Linux OS will scan for available Wi-Fi networks on your PC. Find the tool with SSID “ICE4_MTIxxxxxxxxx” (where xxxxxxxxx is your tool unique serial number), and use the password “microchip” to connect to it.
Now go back to the “Manage Network Tools” dialog and click on the Scan button, which will list your emulator under “Active Discovered Network Tools”. Select the checkbox for your tool and close the dialog.
Wi-Fi AP: On Windows 10 computers, you may see the message “No Internet, Secured” and yet the button will say “Disconnect” showing that there is a connection. This message means that the emulator is connected as a router/AP but not by direct connection (Ethernet.)
If your emulator is not found under “Active Discovered Network Tools”, you can manually enter information in the “User Specified Network Tools” section. You must know the IP address of the tool (by the way of network admin or static IP assignment.)

Connect to a Target

See the table below for the pin-out of the 40-pin connector on your target. It is recommended that you connect your target to the MPLAB ICE 4 using the high- speed 40-pin cable for best debug performance. However, you may use one of the legacy adapters provided in the MPLAB ICE 4 kit between the cable and an existing target, but this will likely degrade performance.
