SCAN2G Scan Converter/scaler

SCAN2G big picture

Video monitors designed to operate from old PC standards such as EGA or CGA have become expensive and difficult to source. They are also not future upgrade compatible.

The main problem is due to the low frequency of their horizontal deflection or scanning system. The C.A. Designs scan converter SCAN2G reads the original video signals into solid state memory at the original frequency and, almost simultaneously, writes this signal out again at a new horizontal frequency. The output signal is processed to be made compatible with standard, low cost and easily available monitors used with current PCs. The SCAN2G contains a scaler, so that the video output can be made to fill the monitor screen.

The SCAN2G module connects directly with the signal source via a 9-way D male connector.

  • Video Input
    accepts TTL video (8, 16, or 64 colour)
  • Video Output
    via 15-way high-density D female socket (VGA type)
  • Power Supply
    9 to 12v external PSU on a DC coaxial connector with centre pin positive

They have a range of manual adjustments to modify the signal capture and picture position. These adjustments are made with a standard PC keyboard (PS/2 style).

Adjustments made are stored in non-volatile memory and are retained when power is off (default settings can be restored if required).

Note that the SCAN2G can scale the picture horizontally and vertically, but will not change the vertical frequency.
