Half duplex is normal,it only menas that your device is either receiving or sending not at the same time. Full duplex is also normal meaning the device can send and receive at the same time. Your sequence frame added does nothing in LabVIEW except for the single frame around the wait ms, that is a correct frame because it has no error in/error out. In fact Everything that is connected by wire in LabVIEW is executed in that order. This is called sequencing by wiring! And for IO it is very nice.

But did you already look at the advanced serail read and write. Half duplex is normal,it only menas that your device is either receiving or sending not at the same time.

LabVIEW: Visa serial read timeout. Can someone explain what is going on (in the visa config serial vi Front Panel the termination character seems to always return to LF even when I try setting to 0, is it possible putting the timer. Visa serial read timeout RavensFan. Veterinarnaya klinicheskaya patologiya m dzhekson3661431. Knight of NI ‎ 04:06 PM. If FALSE, the VI_ATTR_ASRL_END_IN attribute is set to 0 (None) and the serial device does not recognize the termination char. Termination char calls for termination of the read operation. The read operation terminates when the termination char is read from the serial device. 0xA is the hex equivalent of a linefeed character ( n).

This is called sequencing by wiring! And for IO it is very nice. But did you already look at the advanced serail read and write.

Solution There are several reasons why you might receive this error message, the most common of which are detailed below: A) You may not have the correct driver installed. Ensure you have the right driver for your hardware.

Some common ones are: • (for instruments using serial or GPIB communications) • (for instruments using serial communication as RS232, RS422, RS485, etc) • (for instruments using GPIB communications) Note: You must install NI-488.2 driver software before installing any new NI GPIB hardware devices so Windows can detect them. Also ensure that you have the installed. Compatibility information can be found in the readme file for your driver. B) The port isn’t connected, the wrong port is selected, or the port is not being able to send/receive data. Check the instrument is properly plugged in to the port you're using.

C)Try a different system with the same drivers. The COM ports could be corrupted or not working in the original machine. D) A timeout error could also result from the wrong command strings written to the drivers. Check the command strings sent to the VISA Read and VISA Write calls and ensure that they are written in the proper syntax for your instrument. Note: A new line or carriage return is often required at the end of a command. A good way to test this in LabVIEW is to right-click the command string control on the front panel and change the display to ' ' Codes Display mode. In this mode, a carriage return is r, a line feed is n, and an end of line is r n.
