® CyberResearch Serial Communications COML 106U(-X)-D25 Introduction Overview The CyberResearch, Inc. COML 106U is a one channel PCI Bus serial I/O adapter for the PC and compatibles. It provides one field selectable RS-232/422/485/530 serial port supporting asynchronous data rates up to 460.8K bps as well as isochronous data rates up to the speed of the supplied clock. Now, with this card, you can use your standard communications software and connect over a clocked digital communications line.
® CyberResearch Serial Communications COML 106U(-X)-D25 Card Setup RS-485 Enable Modes RS-485 is ideal for multi-drop or network environments. RS-485 requires a tri-state driver that will allow the electrical presence of the driver to be removed from the line. The driver is in a tri-state or high impedance condition when this occurs. Only one driver may be active at a time and the other driver(s) must be tri-stated.

This is selectable via two 24 pin DIP-shunts at E1and E2. Please use the following illustration to aid in the configuration of your electrical interface.
® CyberResearch Serial Communications COML 106U(-X)-D25 Clock Modes The COML 106U employs a unique clocking option that allows the end user to select from divide by 8 and divide by 1 clocking modes. These modes are selected at Header E6. To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, … 115.2K Bps ) place the jumper in the divide by 8 mode (silk-screen D8).

COML 106U(-X)-D25 ® CyberResearch Serial Communications Appendix B - Electrical Interface RS-232 Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard.
® CyberResearch Serial Communications COML 106U(-X)-D25 Appendix C - Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends.
