Description

The USB-KOYO is a USB-to-PLC programming cable designed for communication between a
PC and Koyo PLCs. Koyo PLCs is commonly branded under various names, such as Automation
Direct (e.g., Direct LOGIC series) or other OEMs. This cable simplifies PLC programming,
monitoring, and troubleshooting tasks by providing a USB interface for systems that previously
required RS232 serial connections.
Key Features:
1. Connection Type:
USB-A connector on one end for PC connectivity.
A mini-DIN 8-pin connector or DB9 connector (depending on the model) for interfacing
with Koyo PLCs.
2. Compatibility:
Designed for Koyo PLCs, including the Direct LOGIC series (DL05, DL06, DL205, DL305,
and DL405).
Works seamlessly with programming software such as Direct SOFT.
3. Built-in USB-to-RS232 Converter:
Incorporates a USB-to-RS232 or USB-to-RS422/485 conversion chip, enabling
compatibility with PLCs using serial protocols.
4. Driver Support:
Compatible with most Windows operating systems (Windows XP/7/8/10/11, 32-bit and
64-bit).
Requires installation of a driver, usually included with the cable or available online.
5. Cable Length:

Typically, 1.8 meters (6 feet) in length, offering convenient flexibility for use in industrial
environments.
6. Applications:
Enables programming, uploading, downloading, and real-time monitoring of PLCs.
Useful for commissioning, diagnostics, and maintenance tasks.
7. Durability:
Sturdy design with industrial-grade materials to handle demanding environments and
frequent use.
8. Ease of Use:
Simplifies setup by eliminating the need for legacy RS232 ports or additional adapters.
Plug-and-play functionality with modern PCs and laptops.
Important Notes:
• Ensure compatibility with your specific Koyo PLC model and programming software before
purchasing.
• Install the necessary driver to establish communication between the PC and PLC.
• Properly handle the cable to avoid damage to the connectors or communication ports.
The USB-KOYO is an essential tool for automation engineers and technicians working with
Koyo PLCs, providing a reliable, modern connection solution for programming and maintaining
these systems.
