Serial port to parallel port cable

This assember is actually a very good assembler for , and other 8 bit micros with 32 bit arithmetic, and a linux version available. TASM is produced by Squak valley software. The serial-to-parallel example program was intended to run on an AT89C using the prototype board that was originally supplied as part of the evaluation kit in our programmer. But the circuit is pretty darn simple, and a competent electronics person could build one up themselves, by hand, if they need to.

Note the pin functions are not shown on the circuit, as the circuit was intended to be a general purpose evaluation board, not just a serial to parallel converter.

The pin functions and a good thorough description are included in the firmware which is one of the parts you should download below. These ports are as fast as 8 bit bus cards and can achieve transfer rates upwards of Kbps. These ports are usually used by non-printer peripheral devices such as external CDROMs, tape drives, hard drives, network adaptors and more. Can do both 8 bit input and output at bus speeds. The specification for this port type was jointly developed by Microsoft and Hewlett-Packard.

ECP ports are distinguished by having DMA capability, on-board FIFOs at least 16 bytes deep, some hardware data compression capability and are generally featured more than other ports. These ports are as fast as 8 bit bus cards and can achieve transfer rates upwards of 1 Mbps and faster on PCs whose buses will support it.

The design is capable of faster transfer rates in the future. As explained, there are different LPT ports, but all use the same parallel cable for direct transfer between two hosts.. Note: One wire should be attached to the metal body of the male pins on both sides; this is also shown as the "metal body" on the diagram. Deal with bandwidth spikes Free Download.

In serial communication, the chunks of the data are sent one after the other. In contrast, in parallel communication, all these chunks can be transmitted simultaneously. You can refer to the article difference between serial and parallel transmission to understand the concept in detail. Before understanding each type of port individually, we must be aware of what a port is?

A port is a docking point with the help of which the various devices can be linked to a computer or other devices. There is a huge significance of these ports because, without it, the computers cannot be used at its maximum. It facilitates in creating communication between the devices and the CPU. Multiple bits at the same time. As mentioned above that the serial port is an interface used for attaching the serial lines where the serial communication can be attained.

In these ports a 9-pin D shaped connector can be docked which connects to the transmission line. As we know that the serial transmission obtained by a single wire and only a single stream of a bit is transferred from one end to the other end.

So, like parallel transmission, there is no data speed mismatch problem. Therefore, the wire length can be extended as required. The below-given diagram shows the DB-9 pin.
