About EW2

The EW2 scan doubler enables a VPE editor with CGA (TTL) video display to be connected to a standard VGA / XGA monitor.This applies to VPE-131 through VPE-251 editors.  VPE-300 and DPE-500 series editors are already VGA compatible.

CGA requires a monitor that will lock to a lower frequency horizontal scan than is supported by standard VGA monitors.  The EW2 scan doubler reads the original video signals into memory at the original frequency and sends a signal out at twice the original rate. Due to the technology involved, occasionally pixels are misplaced. The output signal is compatible with standard, low-cost and easily available VGA monitors.

The EW2 module (3.9 in. x 2.3 in. x 1.1 in.) accepts CGA video input signals.  It connects directly to the VPE editor via a 9-pin D male to 9-pin D female lead supplied by Editware.

The output of the EW2 is as follows when using an Editware Editor: Output standard = VGA 640x480 mode; Resolution = 640 horizontal x 480 vertical pixels; Horizontal Sync Frequency = 31.5KHz; Vertical Sync Frequency = 50Hz PAL and 60Hz NTSC.

Video is output via a 15-pin high density D female socket. Power is supplied by a 9v to 12v external Power Supply on a DC coaxial connector with the center pin positive.

For non-Editware editor applications, see Extended EW-2 Adjustments for non-Editware Equipment at the end of this document.
