and the DSAPilot

No computer communication

Incorrect connections

Check that EIA-485 cabling to

 

 

both the computer and the

 

 

loudspeaker is wired correctly for

 

 

the +/- signal wires and cable shield.

No computer communication

Incorrect termination

Ensure that a termination is engaged

 

 

at the EIA-485 port at the computer

 

 

and the Terminate Switch is “ON” at

 

 

the loudspeaker at the farthest end of

 

 

the EIA-485 cable run. All other

 

 

Terminate Switches should be “OFF”.
