Video Text Overlay Unit with PC keyboard interface

& On Screen Scrolling Message Function

This unit features the ability to construct scrolling video text overlays from text typed on each of the unit's eight available screen pages. Each message can be up to the length of the entire screen full of characters. The text, and the scrolling feature, are stored when the unit is switched off and scrolling will restart when power is restored. The unit uses the standard UK or US keyboard key mapping, see the documentation. There is no facility to change to the keyboard mappings of other countries.

The RTCKBD-S unit allows a PC keyboard to be used to create text overlays to annotate a video picture. The RTCKBD-S version does not have a counter interface. Instead it features the ability to create and display scrolling text messages. This is designed for use in ATV repeaters. For full details of the unit's operation please see the details and the documentation.
The message you wish to use can be composed either over the unit's internal video signal or live video. The time and date can optionally be displayed in addition to the message.


The RTCKBD-S unit is housed in an ABS plastic enclosure with phono connectors for video in / out and a 2.1mm DC power socket. It is designed to be powered from the same power supply as the camera and so the unit does not have a power switch. Keyboard connection is via a 6-pin mini DIN socket for a PS/2 keyboard. These units will not work with USB only keyboards which require PC operating system support. They will only work with standard PS/2 keyboards and USB keyboards which implement PS/2 functionality. The latter can be connected via a USB to PS/2 adapter. Flexible keyboards similar to the one shown above, not included, are compatible if they have PS/2 functionality. The character size cannot be changed by the user, although some customisation of the character set is possible. Please contact us before you make your order for details of customisation.
