Troubleshooting Q & A 
There is no image on my SDI monitor. 
If  your  source  is  1080p,  your  monitor  may  only 
support 1080i, but not 1080p.  Turn the rotary dial 
to  position  1  to  change  your  1080p  source  to 
1080i. 
There is no image on my SDI monitor. 
Check the color of the status indicator. If the indi-
cator  is  green,  it  means  there  is  power  but  no 
input  source  is  detected,  this  may  be  related  to 
the content protection on the HDMI source.  If this 
is the case, please call Apantac for technical sup-
port at (503) 968-  3000.
I  have  both  the  RJ-45  and  HDMI  input 
plugged in, but there is no image on my SDI 
monitor.   
Push  the  scan  button  once,  it  will  scan  for  the 
active source.  If both RJ45 and HDMI inputs have 
active sources, the RJ45 has priority. 
The status indicator LED is not lit.   
Check for a possible loose power adapter connec-
tion. Use the fastener that comes with the acces-
sories kit to ensure a secure connection.
