Serial Interface Standard Summary, Synchrotech. All four of these standards were written by the EIA (Electronics Industry Association) to allow peripherals and computers to communicate with each other regardless of manufacturer. There are identical government (MIL spec) and international (CCITT) standards. This means that data is transferred one bit at a time using a start bit, 7 or 8 data bits, stop bit(s) and an optional parity bit. Synchronous communication requires an additional clock line between the sender and receiver.

Parallel communication requires a clock line, usually some control signals and several data lines. Both parallel and synchronous communication systems can transfer data faster than asynchronous serial systems but require more wires in the interconnect cables.

Serial WAN Interface Cards This section describes serial WAN interface cards (WICs) and how to connect 1- and 2-port Cisco serial WICs to a network. It contains the following subsections: 1- and 2-Port Serial WICs 2-Port Asynchronous/Synchronous Serial WIC. Hi, Serial Interface is generally based on TDM and for any speed which are less than T1/E1, it genenally works out to be feasible to go for TDM links in which the termination is done on V.35 or G.703 interface. For higher speed links it is generally feasible to go for. The circuit simply consists of a PIC micro, ICSP interface, an RS232 level translator and an HD44780 LCD. Serial LCD display Software The software is contained in two files (note there are many more created by the compiler): 16F877A-serial-lcd.c bit.h bit.h.

Types Of Serial Interface

PC parallel ports are examples of parallel communication. IBM's SDLC and HDLC are synchronous serial communication protocols and have been typically used in mainframe communications. The standards say nothing about the software protocol or how data is framed, addressed, checked for errors or interpreted. It is the standard used on PC COM port hardware. It is designed to connect two systems only and is . It is a robust interface with speeds to 1.

Maximum signal voltages are . Cable length depends on baud rate but is typically 5. The maximum signal voltage levels are .

Ground voltage differences can occur in electrically noisy environments where heavy electrical machinery is operating. It uses differential, or . Each signal requires 2 wires with a ground present in the system. The advantage of this method over RS- 2.

K baud rate, for example. Such a network can have a . Only one device may drive data onto the bus at a time. The standard does not specify the rules for deciding who transmits and when on such a network. That's up to the system designer to define. Both devices need to communicate at an agreed upon data rate (baud rate) such as 1.

KB or 1. 15,2. 00 KB. This protocol has been in use for 1. PC peripherals such as modems.

Sending synchronized information eliminates the need for a start and stop bit with each string of information. Noise which is picked up on both wires is rejected since a differential receiver responds only to the difference in voltage between the wires. A cooperative protocol for the bus ensures that only one transceiver on a bus transmits at any time.
