KBOB   by Versalent   Home

A small low-cost module to convert a standard PC PS/2 keyboard to a simple on-screen text overlay editor for the XBOB-4 video overlay unit from
Decade Engineering . KBOB coupled with the XBOB-4 adds text in selectable fonts on top of your video image so you can embed any relevant messages into your live video stream with ease.

Editing commands use simple, intuitive single keystrokes that implement the   XBOB-4   video unit's command set automatically. By translating the PC keyboards complex scan-codes to the RS232 character sequences of the XBOB's edit-control language, the KBOB provides a low-cost, simple to operate on-screen editor that does not require the use of an expensive PC and therefore can remain conveniently connected and ready to use at any time. Included is a Y power-cable adapter to allow your XBOB-4 wall supply to power both the XBOB-4 and the KBOB.
