COM-8C-LPE

Low Profile PCI Express 8‑channel RS‑232C serial I/O board. Supports up to 921,600 bps with 128‑byte FIFO buffers per channel. Operates as standard Windows/Linux COM ports. Includes standard size bracket for versatile installation.

The COM‑8C‑LPE provides eight 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.

• 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.
• High density — 8 ports on a single board; up to 16 boards per system (128 ports).
• Low Profile / standard — supports both form factors with interchangeable bracket (standard bracket included).

The board uses a 68‑pin on‑board connector. An optional conversion cable (PCE68‑9PS) is available to split into eight standard 9‑pin D‑SUB male connectors. Alternatively, custom cables can be made for direct connection.

• Optional conversion cable — PCE68‑9PS (68‑pin to 9‑pin D‑SUB ×8).
• 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.

• 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.
