Introduction

PCI-Bus Serial Communications up to 460.8 kbps

CyberResearch's COMHP 7801 series are PCI-bus serial cards designed for RS-232 communications at up to 460.8 kbps. The boards come equipped with either the 16554 (COMHP 7801) or 16854 (COMHP 7401-E) standard. The 16554 features programmable baud rates, data format, and interrupt control, plus a 16-byte FIFO buffer. Upgrades to more advanced UARTs are available. The 16854 UART feature a deep 128-byte data buffer, which can increase the speed at which you can acquire data. A larger buffer makes it easier to program high-speed Windows® applications and allows you to achieve even higher data transmission rates (depending on the parameters of your application). This is a worthwhile hardware upgrade for medium- and high-performance applications.

The COMHP 7801 and COMHP 7801-E boards each include a cable breaking out the board's 78-pin connector to eight DB-9 (9-pin) connectors. The COMHP 7801-D25 and COMHP 7801-E-D25 each include a cable breaking out the board's 78-pin connector to eight DB-25 (25-pin) connectors.
