Introduction

Both high-frequency data and multiple data sources demand high speeds from serial communication boards. That's why we offer the half-size CYBM xxxxP (PCI) and xxxxA (ISA) series of boards. Both PCI and ISA versions deliver up to 921.6 kbaud data transfer rates with other software-selectable rates, including 115,200, 230,400, and 460,800 baud. That gives you the ability to match speeds of almost any device in your system. There is a 64-byte input buffer and 64-byte output buffer on each port to make sure that data continues to flow. Models with the suffix I also provide isolation.

To protect the integrity of your data, RS-422/485 cards in the CYBM series offer failsafe open-circuit and short-circuit detection and protection. As the first few bytes of a rapid reply can sometimes lost when using a multitasking operating system, we provide a special device driver that automatically detects the start of the data transmission and gates the transmitter onto the twisted-pair cable. The driver also automatically detects the last stop bit being sent and gates the port off the cable. The automatic gate-on/gate-off operation permits instant response from remote sources, even though the port looks like an ordinary RS-232 COM: port to applications on the host PC.
