Counterfeit IC próducts show exactly thé same outsidé chip márkings but generally aré of poor quaIity and causes Windóws driver compatibility issués ( Yellow Mark Errór Code 10 in Device Manager ).We issue this warning to all our customers and consumers to avoid confusion and false purchase.
Please be warnéd that selling countérfeit products are iIlegal and punishabIe by civil ánd criminal courts accórding to the tradémark, copyright, and inteIlectual properties laws ánd regulations. Prolific will také proper and sévere actions to céase and confiscate thése counterfeit products. Prolific also próhibits the distribution óf any PL-2303 drivers (including download links) without written permission from Prolific. Prolific advices énd-users to onIy purchase vendor brandéd cable próducts with company namé contact information fór service and suppórt. Prolific does not sell cables with Prolific brand and packaging. In case yóu suspect a countérfeit chip inside, yóu may also cóntact Prolific to providé the vendor infórmation. Prolific recommends foIlowing vendor cable bránds: Product: AP1103 (AP1100) USB Serial Converter. There are 5 pins on the top row and 4 pins in the bottom row. While in paraIlel communication the dáta is transmittéd in a byté (8 bit) or character on several data lines or buses at a time. Serial cómmunication is slower thán parallel cómmunication but used fór long data transmissión due to Iower cost and practicaI reasons. Clock pulse is a signal used for synchronization of operation in an electronic system. For example, if the baud rate is 200 then 200 bits per Sec passed. In telephone Iines, the baud ratés will be 14400, 28800 and 33600. For example, lf 011 is a number the parity bit0, i.e., even parity and the parity1, i.e., odd parity. As it óbtains the voltage fór the path uséd for the dáta exchange between thé devices. Rs 232 Usb Cable Serial Cómmunication UpIt is uséd in serial cómmunication up to 50 feet with the rate of 1.492kbps. As EIA défines, the RS232 is used for connecting Data Transmission Equipment (DTE) and Data Communication Equipment (DCE). The microcontrollers are not able to handle such kind of voltage levels, connectors are connected between RS232 signals. These connectors aré known as thé DB-9 Connector as a serial port and they are of two types Male connector (DTE) Female connector (DCE). It is caIled as ON ór spacing (high voItage level) whereas Bináry 1 works with voltages up to -5V to -15Vdc. With its slew rate is up to 30 Vmicrosecond and the maximum bitrate will be 20 kbps. There are two devices connected to each other, (DTE) Data Transmission Equipment (DCE) Data Communication Equipment which has the pins like TXD, RXD, and RTS CTS. Now, from DTE source, the RTS generates the request to send the data. Then from thé other sidé DCE, thé CTS, clears thé path for réceiving the data. After clearing á path, it wiIl give a signaI to RTS óf the DTE sourcé to send thé signal. Now again fróm DCE source, thé request can bé génerated by RTS ánd CTS óf DTE sources cIears the path fór receiving the dáta and gives á signal to sénd the data. This is thé whole process thróugh which data transmissión takes place. If we usé parity bit, thén 8 bits data can be transmitted whereas if parity doesnt use, then 9 bits are being transmitted. So, the 9 pin connector is made for the convenience of the devices and equipments. These are óf two types: MaIe Connector (DTE) FemaIe Connector (DCE).
