COMM+2.PCIe

The Ultra COMM+2.PCIe: 2 Port RS-232/422/485 LP PCIe Adapter is a high-performance serial interface adapter providing two configurable ports for RS-232, RS-422, or RS-485. It supports data rates exceeding 1 Mbps and is ideal for data-intensive applications requiring fast, reliable throughput..

  • Detail
  • Special Features
  • Specification

The Ultra COMM+2.PCIe adapter offers robust, ultra-fast communication through two serial ports, each configurable for RS-232, RS-422, or RS-485. Designed with high-speed UARTs and 256-byte FIFOs, it supports asynchronous data rates exceeding 1 Mbps, making it perfect for high-throughput serial communication in demanding applications. The DIP switch allows easy configuration for interface and line termination, with the option for software override through the Windows driver. For added reliability, RS-485 mode automatically handles transmitter enablement, eliminating bus contention risks. The Ultra COMM+2.PCIe is compact, fits in low-profile PCIe slots, and includes a standard-profile bracket for versatile installation.
