LABVIEW RS485 DRIVER
I bought a Labview rs485 to RS serial adaptor, based on the research I have so far I have to make labview rs485 that my baud rate, address and data format are matched 8 bit, no parity, 1 stop bit. The command strings and responses are similar. United States.
Industrial Communications. I want to use RS 2-wire mode to communicate with two device.
But I do not know how to connect the two machines. I connect labview rs485 like that. I connect three pins ,normally. Try this to start.

Then the question will be are there just a few commands you will execute which you can predefine the string to send along with its checksum character, or will the VI need to be more flexible to send any kind of command. If the latter, you will need to code how the block checksum character is calculated. You would also have to concatenate the special control characters together labview rs485 I did in the example I attached earlier.

Message 2 of Thanks, I tried that but still it doesn't work. In terms of other relevant info, I am communicating at Baud, 1 stop bit, and parity set to None. I have a decent labview rs485 of Labview experience but absolutely zero communications experience.
The first frame will contain labview rs485 actual serial write function. Also added in this step is the serial port initialize function. Use a numeric constant to set initialize the port to Com2 port 1 and set the port for the write operation by wiring as shown.
A command string of "RD0" must be sent in labview rs485 write operation and it must be followed by a carriage return for the ADR to respond. Enter RD0 followed by a carriage return as the string constant and wire as shown in Figure 7.

The linefeed must be changed manually to a carriage return. You can find more about this i This wireless sensor is available with one of two power options, depending on your application requirements.I am using a Delta temperature controller with RS communication port. In labview rs485 meantime, I have attached a tutorial that outlines a starting point for using RS with LabVIEW. The controller is provided with a RS communication port. Four RS or RS/ serial ports for NI CompactRIO.
National Instruments x serial modules add four RS or RS serial ports to NI CompactRIO systems. These C Series modules interface directly with the CompactRIO field-programmable gate array labview rs485 to offer extreme.
