 | Async (UART)
Click image for more information...
Term describing digital signals that are transmitted without precise clocking. Such signals generally have different frequencies and phase relationships. Asynchronous transmissions usually encapsulate individual characters in control bits (called start and stop bits) that designate the beginning and the end of each character. |

 | HDLC
Click image for more information...
Short for High-level Data Link Control, a transmission protocol used at the data link layer (layer 2) of the OSI seven layer model for data communications. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors. |

| HDQ Bus
Click image for more information...
The HDQ bus is a master-slave bus system using a simple one-wire, asynchronous, bidirectional, serial interface with a bit-rate of about 5-Kbit/s. The bus line is driven by open collector devices and therefore requires an external pull-up resistor. The relatively slow bit rate is sufficient for reading out as well as setting registers in battery monitor ICs. |

|
| Manchester Code
Click image for more information...
The Manchester code (also known as Phase Encoding) is a line code in which the encoding of each data bit has at least one transition and occupies the same time. It is, therefore, self-clocking, which means that a clock signal can be recovered from the encoded data. |
