2. Package Contents
- Manhattan 158220 PCI Parallel Adapter Card
- Standard-height bracket (pre-installed)
- Low-profile bracket (for small form factor cases)
- Driver CD (may not be required for modern operating systems)
3. System Requirements
- Available PCI expansion slot (not PCI Express)
- Compatible operating system (e.g., Windows XP/Vista/7/8/10, Linux)
- Desktop computer with an accessible interior
4. Setup and Installation
4.1 Safety Precautions
- Always power off your computer and unplug it from the wall outlet before opening the case.
- Discharge any static electricity by touching a grounded metal object (e.g., the computer chassis) before handling internal components.
- Handle the PCI card by its edges to avoid touching the gold connectors or components.
4.2 Physical Installation
- Power off your computer and disconnect all cables.
- Open the computer case. Refer to your computer's manual for specific instructions on how to open it.
- Locate an available PCI expansion slot on your motherboard. These are typically white or cream-colored slots, distinct from shorter PCIe slots.
- Remove the metal slot cover corresponding to the chosen PCI slot from the back of your computer case.
- If necessary, replace the standard-height bracket on the card with the low-profile bracket provided, by unscrewing the two small screws holding the bracket to the card, swapping the brackets, and re-securing the screws.
- Carefully align the Manhattan 158220 PCI Parallel Adapter Card with the chosen PCI slot.
- Apply even, firm pressure to both ends of the card until it is fully seated in the slot. Ensure the gold connectors are completely inserted.
- Secure the card to the computer case using the screw from the removed slot cover or a similar screw.
- Close the computer case and reconnect all cables.

4.3 Driver Installation
- Power on your computer.
- For most modern operating systems (e.g., Windows 7/8/10), the system should automatically detect the new hardware and install the necessary drivers. Allow the operating system to complete this process.
- If automatic driver installation fails or if you are using an older operating system, insert the provided driver CD into your computer's optical drive and follow the on-screen instructions. Alternatively, visit the Manhattan website for the latest drivers.
- After driver installation, it may be necessary to restart your computer for the changes to take effect.
5. Operating Instructions
Once the Manhattan 158220 PCI Parallel Adapter Card is successfully installed and its drivers are loaded, the parallel port will be available for use by your operating system and applications.
- Connect your parallel device: Plug the DB25 cable from your parallel peripheral (e.g., printer, scanner, CNC machine) into the DB25 port on the adapter card.
- Verify device recognition: Check your operating system's Device Manager (Windows) or equivalent utility to ensure the connected device is recognized and functioning correctly.
- Use with applications: Configure your software applications to use the newly installed parallel port for communication with your peripheral device.
