The ACT/Technico 8012 is a 4-port RS-232/422/485 serial communication card designed for industrial and embedded applications. Below are its key features and specifications:
Key Features:
-
4 independent serial ports supporting RS-232, RS-422, and RS-485 (software-selectable per port).
-
PCI interface (commonly used in industrial PCs and embedded systems).
-
High-speed communication (baud rates up to 921.6 Kbps or higher, depending on the UART chip used).
-
Optical isolation (available in some models for protection against electrical noise and surges).
-
Automatic RS-485 data direction control (solves common driver control issues in multi-drop networks).
-
Wide operating temperature range (suitable for harsh industrial environments).
Typical Applications:
-
Industrial automation (PLC communication, CNC machines).
-
Data acquisition systems.
-
POS terminals and kiosks.
-
Legacy device connectivity (e.g., barcode scanners, scales, sensors).
-
Building automation (HVAC, access control).
Driver & Compatibility:
-
Supports Windows (XP/7/10/11), Linux, and some real-time OSes.
-
May require manufacturer-provided drivers for full functionality.
