OSD measurement card
<
The OSD card is intended for subtitling the TV image from a video camera in the analog PAL/SECAM standard.
The selected positions of the screen can thus primarily display measured values,
both read from the serial line (RS485) and measured directly at the card inputs (incremental sensor for measuring length, logic and analog inputs).
The RTC circuit allows you to display the date and time. It is possible to connect a PC keyboard, the controller SW contains a simple text editor.
Lines or pages of text can be stored in permanent memory, and then inserted into the text by the editor.
