Internally, we now stick to a particular chipset that we have found to be the most reliable because overall its just less headache.FTDI based adaptors seem to be the most reliable, although Im not saying this is going to be the same for everyone).
So if youve already got a Serial Port on your PC, your USB to Serial device will be operating on a different one. Youll need to change the port to match which one your device is plugged into. If I remember correctly (Im going back a few years), the main problem was that each time the adapter was plugged in it had a different COM port or the settings were totally different. Serial Port Overrun Error Labview Drivers In MAXI also had to synchronize the VISA drivers in MAX to what Windows had occasionally. But If you have other application that takes these port it have to assign new port to that USB. But, I dont understand why this happen for normal RS232 pc port and dont happen with FTDI USB converter. So, why does this error occurs only when I use the pc rs232 and doesnt occur when I use usb-adapter. This loopback plug can come in extremely handy when writing Serial RS232. The Serial Port is harder to interface than the Parallel Port. UART. On the software side of things, there are many more registers that you. Serial Port Overrun Error Labview Serial Data TransferSo what are the advantages of using serial data transfer rather than parallel. The serial port transmits a 1 as -3 to -25 volts and a 0 as 3 to 25 volts where as a parallel port transmits a 0 as 0v and a 1 as 5v. Therefore the serial port can have a maximum swing of 50V compared to the parallel port which has a maximum swing of 5 Volts. Therefore cable loss is not going to be as much of a problem for serial cables than they are for parallel. If your device needs to be mounted a far distance away from the computer then 3 core cable (Null Modem Configuration) is going to be a lot cheaper that running 19 or 25 core cable. However you must take into account the cost of the interfacing at each end. You may of seen many electronic diaries and palmtop computers which have infra red capabilities build in. However could you imagine transmitting 8 bits of data at the one time across the room and being able to (from the devices point of view) decipher which bits are which Therefore serial transmission is used where one bit is sent at a time. IrDA-1 (The first infra red specifications) was capable of 115.2k baud and was interfaced into a UART. The pulse length however was cut down to 316th of a RS232 bit length to conserve power considering these devices are mainly used on diaries, laptops and palmtops. Microcontrollers have also proven to be quite popular recently. Many of. Devices which use serial cables for their communication are split into two. Terminal Equipment.) Data Communications Equipment are devices such as your. The electrical specifications of the serial port is contained in the EIA. An open circuit voltage should never exceed 25 volts. In Reference to GND). Take note of this one). This is commonly used as a cheap way to network games or to transfer files between computers using Zmodem Protocol, Xmodem Protocol etc. This can also be used with many Microprocessor Development Systems. The Data Terminal Ready is looped back to Data Set Ready and Carrier Detect. All left to worry about now is the Request to Send and Clear To Send. As. Notice that the ring indicator is not connected to anything of each end. This line is only used to tell the computer that there is a ringing signal.
