  • RS-485 line termination, pull-up and pull-down resistors for each port are selectable via dipswitch
  • RS-485 ECHO can be enabled/disabled via dipswitch
  • Automatic RS-485 enable/disable in hardware
  • PCI Express X1 compliant
  • Compatible with low profile PCI Express slots
  • Included 36" cable terminates to four DB9M connectors (Item# CA200-ROHS)
The 7402e low profile PCI Express serial interface provides four serial ports, each individually field-configurable for RS-422 or RS-485 communications. The board uses a 16C954 UART with 128-byte Tx/Rx FIFOs that enables data rates to 921.6K bps for reliable high-speed communications in data intensive applications.

This high-performance UART includes 9-bit framing support and is register compatible with legacy 16550 software applications. In addition, the board derives a 62.5MHz clock from the PCI Express link. This ultra-high speed clock is divided by a flexible 8-bit clock prescalar with 1/8 steps to provide support for the widest range of standard and non-standard baud rates.

In RS-485 mode the board provides automatic control of the RS-485 driver in hardware, eliminating the need for application software control. This allows the 7402e to be used with standard serial communications applications and removes the risk of bus contention and data corruption. Additionally, RS-485 network termination, critical to robust multi-drop communication, can be selectively added to the circuit via DIP-switches.

Sealevel SeaCOM software driver and utilities make installation and operation easy using Microsoft Windows and Linux operating systems.

The 7402e is a PCI Express X1 board compatible with any low profile PCI Express slot. If you have a standard size PCI Express slot, please order the 7402eS. Both versions ship with a 36" cable that terminates to four DB9M connectors.
