Understanding Ultimarc's I-PAC 2 and I-PAC 4 Encoders

If you're a gaming enthusiast or hobbyist interested in building your own arcade machine, chances are you've come across Ultimarc's I-PAC line of encoders. In this post, we'll delve into what the I-PAC 2 and I-PAC 4 are, how to set them up, and some basic troubleshooting tips to ensure your device operates flawlessly.

What is an I-PAC?

I-PAC, short for Input to PC Converter, is a series of encoders designed specifically for interfacing arcade controls (such as joysticks and buttons) with a computer or Raspberry Pi. Ultimarc has engineered these devices to mimic keyboard inputs, making them compatible with virtually all PC-based games, emulators, and custom applications.

The Difference Between I-PAC 2 and I-PAC 4

Both the I-PAC 2 and I-PAC 4 serve the same primary purpose, but they differ in the number of inputs and features:

- **I-PAC 2:** This model allows you to connect up to 32 inputs (buttons and controls) to your system. It’s a perfect choice for classic arcade setups where you might want to control a joystick, buttons, and potentially a few additional functions.

- **I-PAC 4:** If your needs extend to a more complex setup—perhaps supporting four-player capabilities or additional controls—the I-PAC 4 can accommodate up to 64 inputs. This makes it ideal for larger arcade arrangements or multiplayer options where each player has multiple controls.

How to Set Up an I-PAC

Setting up an I-PAC encoder is a straightforward process, but precision is key to ensuring everything operates seamlessly.

1. **Wiring:** Start by wiring your arcade controls to the appropriate terminals on the I-PAC. Each terminal is labeled, so you'll know exactly where to connect your buttons and joystick inputs. Make sure to use quality wire and secure connections to avoid any intermittent signals.

2. **Connect the I-PAC to PC:** Once you have everything wired together, connect the I-PAC to your computer using a USB cable. The I-PAC will communicate instantly with your system, and you should hear the familiar sound of new hardware being recognized.

3. **Configure Software (if necessary):** In most cases, there's no additional software needed as the I-PAC is treated as a standard keyboard. However, if you have specific configurations or macros in mind, you may need to use Ultimarc's configuration tools or a third-party key mapping software.

Basic Fault Finding

If you encounter issues after wiring up your I-PAC, here are some basic troubleshooting steps:

1. **Check Your Connections:** Ensure that all wires are properly connected to the appropriate terminals. Loose or damaged wires can lead to non-responsive controls.

2. **Inspect USB Connection:** Confirm that the USB cable is securely connected to both the I-PAC and your computer. If the device is not recognized, try using a different USB port or cable.

3. **Test Button Inputs:** Using a simple text editor, press each button connected to the I-PAC. You should see corresponding key presses appearing on screen. If not, double-check your wiring and ensure your buttons are functioning.

4. **Power Up Sequences:** Make sure your I-PAC is powered on, and the PC is booted up before connecting the USB. Some encoders need to be plugged in while the computer is powered on.

5. **Firmware Updates:** Occasionally, a firmware update may resolve compatibility issues. Check Ultimarc's website for any available downloads and instructions.


Ultimarc's I-PAC 2 and I-PAC 4 encoders represent a solid choice for anyone looking to construct their own arcade experience. With the ease of setup and a vast potential for customization, you can create an arcade machine that fits your specific gaming preferences. Just remember to follow the wiring instructions carefully and troubleshoot methodically if things don’t work as expected. Happy gaming!
