TXDU

Hello, I'm trying to query a device via ascii commands to retrieve measurement data from it. I need to send the following ascii command "Q/D<CR><LF>" to a KE-40B1 particle counter. It is then supposed to respond with an ASCII string in response similar to this: ""D/KS-XX tMin [vML], Value1, Value2.............ValueN <CR>" I'm using a CJ2H PLC with an CJ1W-SCU21-V1 serial communications unit. I'm relatively new to the PLC world. From research, it looks like TXDU/RXDU are my best bet for commands? I need help deciding the best route to go here and a little help setting these up. How do I set the control words to handle these ascii commands and responses? Any help in this matter would be awesome........
