The switching transition of HQView can be set to Freeze, Blank, Fast Fade and Slow Fade. Freeze halts

the prior channel image until the new channel image is stable. Blank switches the output to show a

black screen instead of the last channel image. Fast and slow fade have the prior channel image faded

out and fade into the new channel video image once it is stable.

3.10.4. Display Mode

The “Display Mode” can be set to either Low Latency or Best Picture. In Best Picture optimum image

processing is applied, whereas in Low Latency mode the lowest latency is achieved. The flicker of

interlaced video is not suppressed totally for the latter setting. Thus it has the disadvantage of

conventional CRT TVs, but also their advantage of almost no delay in response, which is important for

applications such as gaming, simulation or imaging in medical treatment.

3.10.5. Menu Settings

This menu provides items to change the menu position and menu display time, i.e. the time after which

the OSD is switched off again with no user interaction. OSD Messages can be activated and

deactivated.

The menu language can be altered and the keypad can be locked. Either all keys or the menu and

menu navigational keys can be locked. To unlock the keypad a combination of keys has to be pressed

at the same time. The locking of the keyboard is accompanied by a message: Keypad is locked. Press

Menu/Up/Down to unlock. When successfully unlocking the keypad the message shows up: Keypad

unlocked.

3.10.6. Network Settings

The Network Settings menu allows to configure the HQView-325 TCP/IP address. Under Address Type

a static or DHCP leased address can be chosen. The static address and Netmask need to be entered

manually.

The Network Settings menu has a section with information on the DHCP Status and IP address

assigned to the board, as well as the fixed MAC Address programmed into the HQView-325. The DHCP

status is Off when static assignment is used or it displays an address when DHCP has leased an

address accordingly or it is None assigned if the lease was not successful.

Note: When changing from DHCP to Static mode or vice versa it is strongly recommended that

HQView-325 is powered down after such a change, then powered back up, so that it is properly

recognised by other devices on the network.

3.10.7. Factory Defaults

This button let you restore all settings to the default values of the HQView-325, thus, provide a means to

get back to a known (good) system state. A requestor will come up and ask to confirm prior to actual

restore.
