​Question:

How do I troubleshoot DXLink connection issues?

Answer:

Telnet to the DXLINK box and type: show vs100 stats
The return data will be in the following format:

>show vs100 stats
---------------------------------------------------------------------------
VS100 RX Local Status:
Link Status: HDBaseT link ON
HDMI Status: HDCP ON
Op Mode    : HDBaseT Mode
Cable Len  : 46m (Valid for HDBaseT and Long Reach Op Modes)
MSE(db)    : ChA: -17, ChB: -18, ChC: -18, ChD: -19
 
VS100 RX Remote Status (Not valid for local No Link)
Link Status: HDBaseT link ON
HDMI Status: HDCP ON
Op Mode    : HDBaseT Mode
Cable Len  : 56m (Valid for HDBaseT and Long Reach Op Modes)
5V/HPD     : 5

The most important parts are the MSE values which are reported per pair of twisted cables in the run.  The ideal value is -22.  -20 to -22 should give no problems.  -17 is the absolute limit to expect functionality.  However, if there are video glitches, test on a short patch cable or re-terminate the existing cabling.
