Industrial communication boardsSerial and parallel communication boards are the printed circuit boards (PCBs). These boards contain integrated components allowing serial or parallel communication supporting respective protocols. Serial boards use serial protocols to transmit data bit by bit. These are cost effective but relatively slow. On the other hand parallel boards transmit data quite fast with 8, 16, 32, 64 bit parallel lines. But parallel implementation is quite expensive.

Parallel Industrial Communication Boards

Parallel industrial communication board is a broader term. It includes boards offering parallel ports, parallel slots, or parallel interfaces. These boards are integrated into the systems to attain of these three functions. Parallel communication is suitable for small distances. For longer distances it is expensive and un-efficient. Because linger distances the major problem is skew. Skew means bits reaches at destinations not at the same time resulting in data losses or errors. In small distances such as scanner or printer connection parallel boards offer fast and efficient response.

Parallel industrial communication board bus specifications

Parallel industrial communication boards variety of bus standards. These include parallel ATA, PCI (peripheral component interconnect), PCI-e (PCI-express), cPCI (compact PCI), PCI-X (PCI extended), PC / 104, PC / 104 –plus, IEEE protocols such as 1284, and Advanced TCA (advanced telecommunication architecture). Form factor of parallel industrial communication boards are selected according to the bus standards. Compact PCI parallel industrial boards are designed for Industrial PC applications. Your general-purpose motherboards and backplanes can connect PCI industrial boards.

Serial Industrial communication boards

Serial industrial communication boards include serial ports, serial interfaces, and serial cards. These are available in a variety. A multi-port serial card offers numbers of external (out through computer case) serial connectors such as RJ 45, DB 9 and DB 25. Multi port boards are inserted into ISA or PCI slots.

Serial industrial communication board Specifications

Form factor is the most important issue to consider while selecting a serial communication industrial board. Its form factor also depends upon the serial communication standard it is required for. IN common you can find serial boards offering serial interfaces (RS 232, RS 422, and RS 485), USB, FireWire, S-ATA (Serial Advanced Technology Attachment), and IEEE 802.11 standards.

Serial Industrial Communication boards

Serial industrial communication boards are suitable for near as well as distant communication. For close equipment these boards offer ports for your system to connect keyboards, modems, or mouse. You'll find USB mice and keyboards common these days. You can attach CD / DVD ROMs through Serial ATA. 802.11 standard offers wireless local area network (WLAN) communication. Ethernet networks also use serial communication boards for communication.
