Product Features
Technical Overview
The USB-SER adapter supports both RS232 and RS485 signal protocols, offering versatility for different serial communication standards. RS232 connectivity uses a 4-conductor 22 AWG shielded cable for point-to-point communication, while RS485 employs a 2-pair 22 AWG CAT5 cable for multi-drop networks, allowing connection to multiple devices over longer distances.
This adapter is fully compliant with USB 1.1 and USB 2.0 specifications, ensuring broad compatibility with modern computing hardware. It operates within a temperature range of 5°C to 70°C (41°F to 158°F), making it suitable for both climate-controlled offices and industrial environments with variable conditions.

Deployment / Use Cases
The USB-SER adapter is specifically designed for access control system integration, enabling communication between modern Windows-based management software and legacy Keyscan control boards (PC109x or later). This allows facilities to maintain their existing access control hardware while upgrading to current computer systems and software platforms.
Beyond access control, this adapter serves industrial automation applications where PLCs, sensors, or machinery use serial communication. It's equally valuable in commercial settings for connecting point-of-sale systems, time clocks, or other serial-based equipment to modern computers. The compact form factor makes it ideal for space-constrained installations such as control cabinets, server racks, or behind-desk deployments.
Access Control Modernization
Bridge older Keyscan access control panels to current Windows computers running management software, extending the life of existing security infrastructure.
Industrial Equipment Integration
Connect serial-based industrial devices to monitoring or control computers for data collection, remote management, or system integration.
Physical Profile
The adapter features a compact plastic housing measuring 2.76 inches (70 mm) in height and 0.75 inches (19 mm) in width. This slender profile allows installation in tight spaces within control panels, behind equipment, or alongside computer workstations. The lightweight construction and durable plastic material make it suitable for both permanent installations and temporary deployments where equipment may be relocated between sites.

FAQ
What communication protocols does the USB-SER adapter support?
The Keyscan USB-SER adapter supports both RS232 and RS485 serial communication protocols. RS232 is typically used for point-to-point connections between a computer and a single device, while RS485 supports multi-drop networks allowing connection to multiple devices over longer distances. This dual-protocol capability makes the adapter versatile for different types of serial equipment in access control, industrial, and commercial environments.
Does this adapter require external power or special cables?
No external power supply is needed. The USB-SER adapter draws power directly from the host computer's USB port, simplifying installation and reducing cable clutter. The package includes a 6-foot USB extension cable for flexible positioning. For serial connections, standard RS232 uses a 4-conductor 22 AWG shielded cable, while RS485 uses a 2-pair 22 AWG CAT5 cable, both of which must be sourced separately based on your specific application requirements.
