Video Text Overlay Unit with PC keyboard interface, Real Time Clock & On Screen Counter RTCKBD-E Order RTCKBD Order Documentation The RTCKBD unit allows a PC keyboard to be used to create text overlays to annotate a video picture. It is primarily designed for video inspection tasks such as drainage, construction and agriculture. For full details of the unit's operation please see the documentation. This unit features the ability to construct scrolling video text overlays from text typed on each of the unit's four available screen pages. Text, and the scrolling feature, are stored when the unit is switched off and scrolling will restart when power is restored. The RTCKBD-E 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. To use the RTCKBD you will need to make connections for the keyboard, video in, video out and power as described on the video overlay board connections page.
