Troubleshooting Serial Communications

Here are some basic troubleshooting guidelines.

No Communications

Is all the cabling correct? 

• Add a null-modem adaptor and see if that resolves the issue.

Is the right COM port selected in the communication settings?

• If using a USB to serial adaptor, use the Windows Device Manager to find the 

correct COM port.

Are the communication settings correct? Is the software set for 9600,N,8,1?

• If the problem is with a LiQuilaz II, check the instrument’s communications setup 

screen.

Is hardware flow control enabled? 

• If so, disable it.

Dropped Characters or Strange Characters

Is the baud rate correct?

• Verify that hardware flow control is not enabled.

Is there a problem with the serial port on the PC? 

• Bad USB to Serial adaptor drivers can cause issues.

Unexpected Characters

• If there are extra blank lines, check the <CR> and <LF> input translation. 

• If characters are duplicated, half duplex mode may be enabled. Use full duplex 

mode.
