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”.
