Serial read and write with an instrument that has no flow control

I have a gaussmeter that has no built in flow control and I keep getting the error 

"VISA: (Hex 0xBFFF0015) Timeout expired before operation completed."

I'm using the example included with labview called "Continuous Write and Read.vi"

My settings look like this. The port is correct (com4) and the command "log status" is a legitimate command according to my instrument's manual. Not sure what I need to do, but it must be something simple.
