Installation (continued)
EDID Learn:
The switch is designed to learn the connected monitor’s EDID upon power up. In the event of
connecng a new monitor to the switch, a power recycle is required.
The switch will indicate to the user the EDID learn process by ashing the front panel’s LEDs. Port
one green will begin to ash for about 10 seconds. When the LEDs stop ashing, the EDID learn
process is done.
The monitor must be connected to the video output connector located in the console space at the
back of the switch during the EDID learn process.
If the read EDID from the connected monitor is idencal to the current stored EDID in the switch
then the EDID learn funcon will be skipped.
When learning the EDID, the audio will be disable unl execung the channel switch or audio
switch commands via RS-232 or Front Panel. Reboong power to the switch will also restore the
audio.

System operation
There are two ways to control the DV-SW8-P: RS-232 Serial Commands, and Front Panel Buons.
All modes of control will allow the user the set their desired conguraons.
front panel control
To switch to an input port, simply push the desired input buon on the front-panel of the switch. If
an input port is selected, the LED of that port will turn on.
There are 8 buons on the front panel of the device, depending on the model. There will be an added
EDID Learn funcon that can be triggered from the Front Panel, this will be triggered as follows:
Hold down the First and Last buon of Front Panel for 3 seconds to force Learn EDID.
rs232 serial control
The DV-SW8-P may also be controlled via RS-232 commands. To use these commands, you must use
HyperTerminal or an alternate terminal applicaon. The sengs for the connecon are as follows:
Baudrate 9600; Data Bits 8; Parity None; Stop Bits 1; Flow Control None.
Once you have connected to the DV-SW8-P via Serial, you will see the DV-SW8-P informaon when
the device starts up.
The following commands can be used for RS-232 with available keyboard hotkeys:
