BCS Commands
To enter BCS commands, the system needs to be attached to a serial control device (see page 59) and running a terminal
emulation program (e.g., the Terminal view in DGX Configuration Software; see page 187). The settings on the PC
serial communication software and the enclosure must correspond to each other (for setting information, see page 60).
Note: BCS tunneling over TCP/IP is also supported (see page 65).
When using a terminal emulation program, command characters are entered and sent to the enclosure's CPU. The
command characters appear on the screen when the enclosure responds. When all of the entered characters appear, the
command has been successfully executed.
Levels in BCS commands are the equivalent of virtual matrices for switching purposes. Level 0 (VM 0) is the default
level (virtual matrix).
To disconnect the factory default switch using a BCS command:
1.
Enter the following BCS command line:
DL0I1T
When the "T" appears, the factory default switch of Input 1 to all outputs on Level 0 is disconnected.
To execute the test switch using a BCS command:
1.
Enter the following BCS command line:
CL0I1O2T
When the "T" appears, the test switch command routes Input 1 to Output 2 on Level 0.
If any other character(s) appear, the command was not successful. In that case, check to see if the source signal is present
(visible and/or audible) at the destination.
To disconnect the test switch using a BCS command:
1.
Enter the following BCS command line:
DL0I1O2T
When the "T" appears, the test switch is disconnected.

Protocol at www.amx.com.
Test Switch Troubleshooting
Note: Normally the Enova DGX Switcher switches non-encrypted content without problems when the display
is non-HDCP compliant. Be aware that when non-encrypted content is being played on a Blu-Ray player,
most players pass the content on as though it was encrypted. Therefore, when a Blu-Ray player sends
originally non-encrypted content as encrypted content to an Enova and the signal is switched to an output
board (e.g., SC Optical Board) or a device that does not support HDCP, the content will not display and the
image will be dark red.
If the display is dark red:
If an HDCP protected source device is switched from an HDMI, DVI, or DXLink Board to an SC Optical Board, the
encrypted video will be blocked on the destination device and replaced with a dark red screen due to an HDCP
authentication failure.
If the image has black bars on all sides:
If the source device is providing video at 1080p @ 60 Hz and black bars appear on all sides of the image:

Set the input on the source device to either a different input resolution or refresh rate (e.g., 1080p @ 50 Hz).
Or
Select a resolution and refresh rate from the PC's graphic driver control panel and be sure to select "Maintain
Display Scaling" as the "Scaling" option.
