Also because of its rigid construction the cable can be used in hard environment. Since no additional firmware installation required for working, the interface can be established at any place and time. The cable is cheap and easily available in the market.

128 byte receive buffer and 256 byte transmit buffer, utilizing buffer smoothing technology to allow for high data throughput.ДЇTDI cables are the best option available for interfacing UART devices to the PC.

Operating temperature range: -40вњ¬ to +85вњ¬.

True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input.

Entire USB protocol handled by the electronics in the cable.

Received Data The data set receives the initial signal via the receive data line (RxD). Data Carrier Detect After a data terminal is detected, a signal is sent to the data set that is going to be transmitted to the terminal. Output can be directly connected to microcontroller UART or I/O. An RS232 pinout 9 pin cable features nine pins: 1.Internal EEPROM with user writable area.Receive and Transmit LED drive signals.Abaixo voc tem a imagem da pinagem do conector, vamos utilizar somente os pinos 2,3 e 5 (2,3 RX/TX, 5 terra) geralmente tem outras conexes e jumpers mas somente com a montagem simples vai funcionar. Vai precisar de um ferro de solda e estanho. No additional firmware programming required. 01 metro de cabo 3 vias (eu utilizei um cabo de udio que tem uma malha bem resistente).Data transfer rates from 300 baud to 3Mbaud at TTL levels.The function of each pin is stated in below table.

If stated in a single sentence, we can use FTDI cable to connect RS232 devices to PC.ДЄs shown in FTDI cable pin diagram, one end of FTDI cable is connected to USB and other end we have six output pins. So they are simple plug and play devices.

The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB and they do not require any additional software installation and setting before using them. The chip handles all the protocol of converting USB data to UART serial data. The 'point of view' of the computer (DTE).FTDI cables are the family of USB to TTL serial UART converter cables and they are incorporated with FT232R IC. The names: 'receive' and 'transmit' should be interpreted from The meaning of the pins are the same on both Data Terminal Equipment andДata Communications Equipment. Nowadays computers used as DTE instead of a terminal. Initially, RS232 ports were used for connecting aДumb terminal (DTE) to a modem (DCE). On the same wire but neither would be able to receive any

If you will do it, then they would both send out signals Therefore, you can't connect two devices that can send data out (DTE-DTE connection) using a straight cable. Unable to receive any signal using this pin. For example, if pin #2 outputs data, then it is You can see examples in the ' SerialДЄll signals of the RS232 port is are unidirectional. There are several cable layouts possible. Two DTE devices (for example, two computers or a computer and an external device). It is possible two connection types between serial ports: straight (pins 2 on both sides are connected) or null-modem (pin #2 is connected to pin #3 on another side).ДЇirst connection type is used between DTE (Data Terminal Equipment) and DCE (Data Communications Equipment) devices (for example, a computer and modem), and the second connection type is used between

How to connect RS232 ports using cablesДЄ serial port is used to connect devices or computers, and therefore it should be connected to another serial port.ДЄn external device or modem that is connected to the serial port has an identical built-in serial Serial Port Monitor software can work with all signal of the RS232 interface. It is possible for all the 6 signal wires, but usually in standard devices these signal pins are used as described in the table above. In other cases the modem may not handle this signal or do something else when DTR is LOW (-12V). For example, a modem can hang up the telephone line when DTR is LOW. 3V)ДЇor example, Advanced Serial Port Monitor can automatically control the DTR signal and set it LOW (-12V) when sends data out.ДЄ modem (or another device) that receives thisДTR signal on another side (if these pins are connected) may do various things. RS232 uses following voltages for signals: ITU V.24 (pins description and names) and V.28 (electrical). RS232 defines both the physical andД®lectrical layers of this interface. Telecommunications Industry Association) issued several RS232 standards. This is defined by the hardware interface and you can't change it.Д«ut all other pins can be controlled by a software and can be used for other tasks (rarely). Only 3 pins of the 9 have a fixed meaning: send, receive and signal Note: DCD can be sometimes labeled as CD Port Pins May Have No Constant Meaning
