Unlike serial communication, parallel communication transmits a full byte of data simultaneously over 8 data lines. There is no standard maximum cable length for parallel communication, but generally the cable lengths are far shorter than for serial, ranging from 6” to 15”.

D-sub) Cable which is less common, but used for connecting a PC to a non-printer peripheral that communicate over parallel (i.e. Centronics) Cable which is used to connect a PC to a parallel printer.
The most common parallel cable is the IEEE 1284-B (i.e. Connecting parallel devices requires specific cables to account for the multiple transmission lines. It requires multiple lines for transmission as opposed to the single wire required for serial communication. Parallel communication and transmission is the process of sending multiple binary digits simultaneously. Yet they also find applications in manufacturing/industrial settings such as CNC machines and monitoring devices such as weight scales and temperature sensors. cash registers, barcode scanners and receipt printers) and for modem and polling communications. For reference, LAVA serial cards are typically used in Point of Sale (POS) environments (i.e. Despite its age, a surprising number of electronic devices are still equipped with a simple UART for debugging. Serial communication is a reliable standard that has been used for decades because it is easy to implement, interface with, and perfect for monitoring devices where data may be occasional and periodic.
The most common standard (RS-232) has a distance limitation of only 15m (or 50ft), but this can be extended by using different cabling mediums (i.e. For example 8-N-1 would be used to transmit data in 8 bit segments with No Parity and 1 Stop Bit. Depending on how the serial port is configured, data can be transmitted in one of several different formats. The maximum baud rate for a standard RS-232 serial port is 115kpbs. baud rate) so in order for both ends to communicate correctly, both the sender and receiver must know the rate that data is being sent, as well as how the byte of data is formed. Each block of data is transmitted at a predetermined speed (i.e. The other lines on a serial port can handle hardware flow control but are not always required. Once a serial device has been connected to a serial port, data is transmitted sequentially over the Tx (transmit) and Rx (receive) lines located on the serial port, with 1s and 0s being measured in reference to the GND (Ground) line. But when connecting a DTE to another DTE, then a null model, or crossover cable is required to connect the ports. When connecting a DTE device to a DCE, a standard straight through cable is required. a barcode scanner), while a DCE would refer to something like a modem.
For most practical purposes a DTE would refer to the serial port on the back of a PC and/or a standard POS device (i.e. There are two types of serial communication equipment: Data Terminal Equipment (DTE) and Data Communications Equipment (DCE). The type of communication equipment that you’re planning to connect to a serial port will dictate the type of cabling required to successfully communicate with the hardware. But for modern purposes serial communication equipment is used to transmit data with cables.

In the most classic sense, Morse code could be considered a version of serial communication. Serial communication and transmission is the process of sending data sequentially, one bit at a time over a communications medium.
This article will provide an overview on what Serial and Parallel communication are, the differences between them, and how their advantages translate into different use applications. While technological advancements have largely transitioned to fast communication standards, serial and parallel still play an important role at LAVA and beyond. LAVA has been designing and manufacturing custom serial interfaces for 36 years, and in that time we established ourselves as industry experts on serial and parallel communication.
