INTRODUCTION
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 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 following is the EW2 output 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 positive center pin.
The standard EW2 unit is programmed with default parameters suitable for a CGA input with a typical VGA
monitor output. It also has a range of manual adjustments to modify the signal capture and picture position.
These adjustments are made with the PS/2 style keyboard supplied by Editware. Adjustments made are stored
in non-volatile memory and retained when power is off (default settings can be restored if required).
For non-Editware editor applications, see EXTENDED EW-2 ADJUSTMENTS FOR NON-EDITWARE
EQUIPMENT at the end of this document.
