DMX STATUS (Green LED)
If the DMX Status LED is on, then the dowser is receiving a DMX signal, and is under DMX control
(local level is set to {00}). If the DMX Status LED is off, then the dowser is not receiving a DMX signal
OR is under local control.
Termination Switch
This switch provides an onboard method of terminating the DMX line. In accordance with DMX
standard practices, if the unit is at the end of a DMX chain, it should be terminated with a 120-ohm
resistance to prevent line reflections, which could cause data errors. By turning this switch on, a 120-
ohm load is added to the DMX line to terminate it. Only use this at the end of a DMX chain.
