High‑Density RS‑232C
for PCI Systems

The COM‑4(PCI)H provides four RS‑232C serial ports on a PCI 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
  • 4 RS-232C ports
  • 921,600 bps max baud rate
  • 128‑byte FIFO (Tx/Rx per channel)
  • Asynchronous serial transfer
  • RTS/CTS/DTR/DSR software control
Compatibility & Expansion
  • Standard Windows/Linux COM ports
  • Up to 16 boards per system
  • Optional conversion cables/units
  • 37‑pin to 9‑pin/25‑pin adapters
  • 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.
  • High density — 4 ports on a single board; up to 16 boards per system (64 ports).
  • Flexible power — supports both 3.3V and 5V PCI slots via jumper selection (depending on board revision).

Connector & Cabling

The board uses a 37‑pin on‑board connector. Optional conversion cables are available to split into four 9‑pin D‑SUB (PCE37/9PS) or four 25‑pin D‑SUB (PCE37/25PS) male connectors. A DIN‑rail mountable conversion unit (CCU‑78F/25M) is also available.

  • Optional conversion cables — PCE37/9PS (37‑pin to 9‑pin D‑SUB ×4), PCE37/25PS (37‑pin to 25‑pin D‑SUB ×4).
  • Optional conversion unit — CCU‑78F/25M (DIN‑rail or wall mount, 78‑pin to 25‑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.

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.
