The DVP824K products can be accessed in a 1.5U high 19” rack compatible chassis. Robust mechanics and logical interface design guarantee easy installation and operation. The box contains 3 pieces of regulated, internal fans. The fans are regulated in order to achieve optimally low noise level and sufficient cooling for the long term, stable operation.
Power Connection
The chassis contains internal power supply supporting all of the international mains electricity standards from 90V up to 265V. The small processor can be switched on and switched off by the following methods.
  • Back panel switch
  • Front panel, standby switch
  • LAN connector based switch-on or switch-off by remote command
Power Switches, standby mode
There are two switches controlling the switch-on and switch-off operation.
The mains switch on the back side and near the 230V mains connector performs full mains SWITCH ON or SWITCH OFF relating to the 230V power. The front switch of the chassis has special function if the back panel mains switch is on. The product can be put into standby phase by using the front panel switch. The very last status and output content is saved during the standby phase. The second push of the front panel switch deactivates the standby phase so the very last state of operation appears.
Please note to switch off first and then remove the power supply cable if opening the chassis for any reason.

Remote switch-on and switch-off
The DVP824K can be switched on and switched off remotely in case of the mains power switch is on. The TCP/IP based remote command can force the DIVIP to standby or can return the product from the standby phase.

Programmed wake-up and standby
The DVP824K contains separate scheduler to wake up the device or send to standby mode. This scheduling can be programmed and works according to the internal calendar clock.
Front LED and push buttons for setup
The front panel LED displays status information for setup and control. There are push buttons for navigation and control inside the setup to handle setting up of basic configuration information
  • Setting of DHCP or fixed IP address and additional LAN parameters
  • Function assignment of signal driving push buttons
  • Setting of RS232C signals’ connection parameters
  • OSD display settings
  • Factory reset setting
Push buttons for signal control
There is a set of push buttons for input signal and a separate set for output signal management. They can work for multiple purposes:
  • The input buttons can select a certain input signal to be displayed on a certain output channel identified by the output button. This can be used for signal display one-by-one, usually for testing.
  • The user can generate layouts and can assign them to push buttons. In this case the push of a certain button recalls the pre-designed layout on a rather straightforward way.

Disable of push button operation
Front panel push button operation can be disabled using a special system setting. In this case user can prevent un-authorized user action from the front panels and so improve system responsibility.

Real time signal handling for perfect customer satisfaction
The DVP824K products perform all operations in real time. So the output signals are displayed in real time from the inputs regardless of the signal resolution, scaling, PIP and number of signals controlled. No drop of frames, no black frames or transitions can be experienced
Unlimited scaling of input signals to outputs
The DVP824K devices contain two output signal scaling engines for each of the output channels. The scaling operation has no limit so the scale up from any input resolution as for example 640×480 or 1024×768 to any output resolution up to 1920×1080, 3840×2160 or even 4098×2160 is possible. The scale down from any input resolution as for example 3840×2160 can be performed to any output resolution as 1280×720 is possible. One of the scaling engines serve the main output while the second one supports the PIP channel. The scaling operation results crystal clear image displayed in real time with no drop of frames.
OSD over output signals (On-Screen-Display)
There is a built-in information text about the current output settings and input connections. This information text can be visualized on the OSD (On-Screen-Display) panel. The visibility settings of the OSD panel can be changed here.
  • Auto: the information panel is automatically displayed in case of any changes in the settings.
  • Yes: the information panel is visualized permanently.
  • No: the information panel is not visible.

By default, the information panel can be seen on the top-left corner of each display output. The position, size, timing, content, background colour, the text colour and the highlighted colour can also be specified in the OSD panel.

Professional HDCP handling
