New PCI Express Board Adds Two RS-232/422/485 Ports

The 7205e PCI Express serial interface provides two serial ports individually configurable for RS-232, RS-422, or RS-485.

  • Utilizes 16C950 UARTs with 128-byte FIFOs for error-free operation in high-speed applications to 921.6K bps.
  • Standard support for 9-bit serial protocol
  • Available for low profile and standard size PCI Express slots
  • Includes cable with two DB-9M connectors

Read about the 7205e low profile and 7205eS standard size PCI Express serial interface adapters.


PCI Express Serial Interface with 16 RS-232 Ports

The 7161e provides sixteen RS-232 serial ports on any computer with a standard size PCI Express slot.

  • Utilizes 16C854 UARTs with 128-byte FIFOs for reliable operation in data intensive applications
  • Supports serial data rates to 460.8K bps
  • Interface is fully PCI Express x1 compliant
  • Includes cables with DB-25M or DB-9M connectors

Tech Lowdown – PCI Express–The Next Generation Bus for the PC

PCI Express is designed as a high-speed upgrade for the 32-bit parallel PCI bus. The PCI Express interface is a bi-directional serial connection that transports data in packets similar to the method used for Ethernet connections. Each point-to-point serial connection, or “lane”, utilizes two pairs of differential data lines. For devices like video cards that require significant data transfer, up to 32 lanes can be stacked together to increase the amount of bandwidth available. The PCI Express x1 (single lane) connector is capable of bidirectional data transfers up to 250MB/s, which can easily handle even sixteen of the fastest high-speed serial ports.
