High‑Speed RS‑232C
in Low Profile Form Factor

The COM‑2C‑LPE provides two RS‑232C serial ports on a Low Profile PCI Express board. It supports data rates up to 921,600 bps and includes 128‑byte FIFO buffers for transmit and receive per channel. The board operates as standard Windows/Linux COM ports using the included COM‑DRV driver.

Performance & Features
  • 921,600 bps max baud rate
  • 128‑byte FIFO (Tx/Rx per channel)
  • Asynchronous serial transfer
  • RTS/CTS/DTR/DSR software control
  • Up to 16 boards per system
Compatibility & Mounting
  • Standard Windows/Linux COM ports
  • Low Profile / standard slot compatible
  • Includes standard size bracket
  • Optional conversion cable available
  • VCCI-A · FCC-A · CE · UKCA

Used as standard COM ports — with COM‑DRV driver, works like built‑in COM ports using Win32 API (DCB structures) or Linux system calls. Supports .NET SerialPort class and PySerial.

Built for Versatile Connectivity

  • High speed — supports baud rates from 30 to 921,600 bps (depending on board revision).
  • FIFO buffers — 128 bytes each for transmit and receive per channel; reduces CPU load during high‑speed communication.
  • Software control — RTS, CTS, DTR, DSR lines can be controlled and monitored via software.
  • Low Profile / standard — supports both form factors with interchangeable bracket (standard bracket included).
  • Board ID — set via SW1 to distinguish multiple boards.

Connector & Cabling

The board uses a 44‑pin on‑board connector. An optional conversion cable (PCE44/9P2S) is available to split into two standard 9‑pin D‑SUB male connectors. Alternatively, custom cables can be made for direct connection.

  • Optional conversion cable — PCE44/9P2S (44‑pin to 9‑pin D‑SUB ×2).
  • Signal lines — TD, RD, RTS, CTS, DTR, DSR, DCD, SG, RI.
  • Cable types — use straight cable for modem connection, crossed (null modem) for PC‑to‑PC connection.
  • Board ID — set via SW1 to distinguish multiple boards.

Certifications & Compliance

  • VCCI Class A — Japanese EMC for commercial/industrial environments.
  • FCC Class A — U.S. emissions compliance for industrial use.
  • CE (EMC Directive Class A + RoHS) — European conformity.
  • UKCA — UK conformity assessed.
