Brightsign serial control of Dynascan LCD

I am attempting to control a Dynascan LCD display that uses RS232 (115200, 8,1,N) from an XD1132.

 

The command to turn a display on is:

01 54 80 00 00 00 00 00 00 AA

The command to turn a display off is:

01 54 00 00 00 00 00 00 00 AA

I see these strings if I watch the output of Dynascan's own display control software.  But I can't seem to get this to work using serial control from my XD1132.  I regularly control LG and Samsung displays using the Brightsign player and serial so I am familiar with it but I am failing with Dynascan.

I have the Presentation Properties - Interactive tab set for 115200, 8, N, 1.  I have tried Protocol-Binary and Protocol-ASCII.  I have tried "Invert Signals" even though I don't even know what that means.  In the command I have tried Send-Serial String (EOL) (no EOL), ASCII and Hex.

 

Any thoughts from anyone?  I imagine there are not many people trying to control Dynascan displays.

  Use these settings on File > Presentation Properties > Interactive tab:

  

   

  Power on command should be 1,84,128,0,0,0,0,0,0,170

  

   

  Power off command should be 1,84,0,0,0,0,0,0,0,170

  

   

  When you publish schedule serial debugging must be switched off:

  Once again you guys are great!  This worked for the DynaScan DS471LT4 (I think most DynaScan displays have everything the same for serial control).

   

  I would like to point out that if you change the Presentation Properties - Interactive Tab - Baud Rate and publish to the player...you must also reboot the player for the new baud rate to take effect.  I implemented your code above and nothing happened...so I began to doubt you until I physically rebooted the player and the commands began to work.
