Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers
Appendix C – DGX_SHELL Commands
channel This command is used to read or write video settings for the designated channel (using the command alone
results in a dump of the entire system).
IMPORTANT: The channel index (BCPUx:y) relates to the physical input or output port on an input or
output board, whose hardware numbering is complex due to the varying orientation of the boards on
different Enova DGX products (see the “Product to Board Slot Correspondence” table on page 245).
We recommend using the variables Ix and Ox to specify the desired input and output channels (e.g., enter
channel -v I25 for Input 25).
NOTE: To persist the -m scaler change to flash (for power on scaler setting), the -p (persist) must also be
sent.
Usage: channel {-a}{-d <hex_string>}{-m <hex_string>}{-o <hex_string>}{-p}
{-s <hex_string>}{-v}{Ix|Ox|BCPU|BCPUx|BCPUx:y|BCPUx:y:z}
Options:
-a ar_policy <HEX_BYTE>
-d flash_dtd <HEX_DTD_STRING>
-m mode <HEX_BYTE> 00 = Auto, 01 = Manual, 02 = Bypass
-o override_dtd <HEX_DTD_STRING>
-p persist
-s sharpness <HEX_BYTE>
-v verbose
Target:
BCPU
BCPUx x = 1-32 (boardID) where x = 1-32 for Enova DGX 6400; x = 1-16 for Enova DGX 3200; x = 1-8 for
Enova DGX 1600; x = 1-4 for Enova 800
BCPUx:y y = 0-3 (channel-hardware order)
BCPUx:y:z z = 0-7 (port)
Example 1:
DGX_SHELL> channel -v BCPU19:0
Output: 9 (BCPU19:0:7) Video: 1920x1080p,59.9Hz Audio: 48 kHz, 16 bits
DTD:
02 3A 80 18 71 38 2D 40
58 2C 45 00 00 00 00 00
00 1E
AUX_MODE:
00 01 00
AUX_POLICY:
01 01 00
AUX_SHARPNESS:
02 01 00
Example 2:
DGX_SHELL> channel -m 02 BCPU7:0 [sets the scaler mode of BCPU7:0 to Bypass (02)]
Output: BCPU7 Channel: 0 port: 0 Video: 1920x1080p,60.0Hz
DGX_SHELL> channel -p BCPU7:0 [persists the power-on scaler mode to flash for BCPU7:0]
Output: BCPU7 Channel: 0 port: 0 Video: 1920x1080p,60.0Hz
clear This command is used to clear the terminal screen.
Usage: clear
date This command displays both run-time clock and system time information and the time of the last NTP (Network
Time Protocol) update.
• rtc is the time held by the real time clock chip. The last updated is the beginning of unix time.
• systime (system time) is the time known by the coldfire and is generated locally.
Usage: date
echo This command is used to print a string back to the terminal.
Usage: echo "string"
Example:
DGX_SHELL> echo "Hello World!"
Hello World!
history This command is used to display a list of previously invoked commands.
Usage: history
