Secura Key SK-ACPE Board: What's New & Why It's the Best for Access Control

What is the Secura Key SK-ACPE Board? The Secura Key SK-ACPE Board is a next-generation access control panel designed to replace and improve upon the SK-ACP model. While it maintains the same core functionality, it introduces several enhancements that make it a faster, more reliable, and easier-to-use solution for managing access control systems. By upgrading key components, the SK-ACPE ensures better performance and more efficient integration into modern security setups.

One of the most significant upgrades is the addition of a built-in Ethernet adapter, eliminating the need for an external module. This built-in feature allows for direct network connectivity, making installation simpler, faster, and more cost-effective. The SK-ACPE is also equipped with a more powerful processor, improving system responsiveness and overall efficiency. These advancements help businesses and facilities maintain secure, streamlined access control without requiring major changes to their existing infrastructure.

Why is the SK-ACPE an Upgrade?

Compared to the older SK-ACP, this new model has:

• Built-in Ethernet: No need for an external adapter; it connects directly to a network.
• Faster Processor: Improves performance and speeds up access control operations.
• Better Efficiency: Reduces hardware requirements and simplifies setup.

What Does The SK-ACPE Mean for Users?

• Easier installation: With Ethernet already included, there's no need for extra parts.
• More reliable performance: The improved processor makes the system run smoother.
• Seamless upgrade: Works just like the SK-ACP, so users don't need to learn a new system.

For businesses looking to upgrade their access control system without a complicated transition, the SK-ACPE offers a modern, hassle-free solution that improves both performance and usability.

SK-ACPE Compatibility and Design

Upgrading access control systems often raises concerns about compatibility, downtime, and installation complexity. The SK-ACPE addresses these issues with a seamless, plug-and-play design, making it an effortless replacement for the SK-ACP. With full software compatibility, minimal hardware modifications, and enhanced features, the SK-ACPE ensures a smooth transition while modernizing access control systems.

How to Configure Input Circuits Using Software?

SK-ACPE Manual

In the SK-ACPE, the physical jumper used to switch input circuits between Normally Closed (NC) and Normally Open (NO) has been removed. Instead, this configuration is now managed directly through the SK-NET software (Version 5.1 or later).

Steps to Configure Input Circuits in SK-NET:

• Ensure You Have SK-NET Version 5.1 or Later:
  • If you are using an older version, update to Version 5.1 to access input configuration settings.
  • If you cannot update, inputs will automatically default to Normally Closed (NC).
• Open SK-NET Software: Launch the SK-NET application on your computer.
• Select the SK-ACPE Board: Navigate to the connected SK-ACPE board within the software interface.
• Locate Input Configuration Settings: Find the section that allows you to modify input circuit settings.
• Choose NC or NO for Each Input: Adjust the settings to either Normally Closed (NC) or Normally Open (NO) based on your system requirements.
• Save and Apply Changes: Confirm the changes and apply them to the SK-ACPE board.

This software-based configuration provides greater flexibility and eliminates the need for physical jumpers, making setup and adjustments easier than before. If SK-NET Version 5.1 is unavailable, the system will default to NC inputs, ensuring continued functionality without manual intervention.

How to Configure RS-232 Signals with Jumper JP1?

The SK-ACPE introduces Jumper JP1, which determines how RS-232 signals are routed. Depending on your setup, you can configure RS-232 communication for either a wireless LAN module or a direct computer connection

Steps to Configure RS-232 Using JP1:

1. Locate Jumper JP1 on the SK-ACPE board.
2. Choose Your Connection Type:
3. For Wireless LAN: Place JP1 in the correct position to enable RS-232 at J12. This allows the board to work with the optional SK-WLSE-LAN module for wireless networking.
4. For Direct Computer Connection: Set JP1 to enable RS-232 at J11/J10. This configuration allows for a wired serial connection to a computer.
5. Secure the Jumper in Place to ensure proper communication.
6. Test the Connection to confirm that the board is communicating correctly with the chosen device.

What are the key differences between the SK-ACPE and the SK-ACP?

The SK-ACPE is designed as a direct replacement for the SK-ACP while introducing several enhancements that improve performance and ease of use. It features an integrated Ethernet adapter, removing the need for an external module and allowing direct LAN connections through the RJ-45 connector (J10). The processing power has been upgraded with a 32-bit ARM Cortex M3 processor, ensuring more efficient operation. Additionally, the SK-ACPE includes improved surge protection with gas discharge tube protectors on the RS-485 bus (J8), reducing the risk of electrical damage. Despite these upgrades, the SK-ACPE retains full compatibility with SK-NET software and maintains the same core functionality as the SK-ACP, allowing for a smooth transition without major system modifications.

How does the SK-ACPE maintain compatibility with existing systems?

The SK-ACPE is fully compatible with SK-NET software versions 3, 4, and 5, ensuring that users do not need to upgrade their existing software. Most connectors retain their original functions, allowing businesses to replace their current SK-ACP boards without significant rewiring. However, the J3 and J4 connectors have been relocated to the side of the board for better accessibility, though this change does not impact functionality. Additionally, the reset button has been moved next to connector J2 for easier access. These design adjustments enhance usability while maintaining the familiar setup that existing users are accustomed to.

How have input configurations and RS-232 connectivity changed?

One key change in the SK-ACPE is the removal of the physical jumper for switching input circuits between Normally Closed (NC) and Normally Open (NO). Instead, these configurations are now managed directly through SK-NET software (Version 5.1 or later). If an older version of SK-NET is used, inputs will default to NC. The board also introduces a new Jumper JP1, which allows users to enable RS-232 signals at different locations. When RS-232 is enabled at J12, it supports the optional SK-WLSE-LAN wireless LAN module, while enabling it at J11/J10 facilitates direct computer connections. These changes streamline system configuration while maintaining flexibility for various setups.

What are the power and LED status updates in the SK-ACPE?

The SK-ACPE now has a redesigned power supply that recommends AC power for optimal performance. It can be powered using a 16.5VAC 40VA transformer, such as the SK-XFRMR, or a 24VDC power supply like the SK-DCPWR. Additionally, the status LEDs have been updated with repositioned placements to improve visibility and provide clearer system indicators. This change enhances monitoring and troubleshooting, making it easier for users to diagnose potential issues. These updates, along with improved surge protection, make the SK-ACPE a more robust and modern access control solution while preserving the ease of installation and operation.
