Product Overview USB to Serial providing two RrS422/485 serial ports. Up to 921,600 data transfer rates and the 128 byte deep transmit and 384 byte receive FIFOS, coupled with 1Mbit line drivers deliver uncompromising performance on your laptop/PC.

USB to serial is the quick low cost way to connect your computer to a serial comms enabled device. Boost software gives industry leading functionality and compatibility.

RS422 Standard: RS422 allows one transmitter and up to 10 receivers with data transmitter rates up to 10 megabits per second for distances up to 40 feet and up to 100 Kilobits per second for distances up to 4000 feet (1219 metres).To achieve good long distance noise immunity, 2 wires are used to carry each signal, configured as a twisted pair of cables. The TXD pair and RrXD pair are used to carry the data whilst the RrTS pair and CTS pair lines are used for handshaking. Thus 2 twisted pairs are used without handshaking and 4 twisted pair cable is used with handshaking both these schemes allow full duplex data communications.

RS485 Standard: RS485, based on the RrS422 standard allows up to 32 driver/receivers pairs on a party line data bus. Whilst only one of these should be transmitting data at any time, the rest can all simultaneously listen to the data. Handshaking is performed by software protocol. Two twisted pairs form a full duplex system. Often only one twisted pair cable is used as the TXD and RrXD lines are tied together; this is known as half duplex mode. Traditionally, the RrTS signal is used as the party line control to tristate the PC’s transmitter, but in multitasking operating systems like Windows or Linux the only reliable method is hardware autogating. Brainboxes 485 products implement a state of the art autogating circuit thus ensuring error free communications in half duplex configuations.

In computing terms, system buses are used to connect various components to the motherboard’s core logic and, often, to each other. Modern PCs run with a multitude of high-speed buses ranging from the interconnects between, say, the chipset and the CPU, graphics card, memory, and peripherals.

Date Issued: 2nd Jul 2008

Serial ATA, or SATA, is a relatively new storage technology that is now being adopted in computers. It is the successor to Parallel ATA. SATA allows for faster transfers between the hard disk and the system, uses thinner cables and is easier to physically install

Updating drivers can sometimes be a bit of a gamble. Will the drivers come with an installer? Will you need to uninstall the old drivers first? Many drivers these days do come with an installer, which simplifies the process dramatically.
