VGA-232 - Serial RS232 to VGA Display

VGA-232 is a small PC Module, developed to solve the need for better displays on POS and Embedded systems, and large readout Meter and Timers applications.
It provides a low cost solution, that allows use of STANDARD, low cost VGA displays, of any size.
Tested with displays from 7" to 24" plus

2012 Firmware & PCB upgrade:

Newest version have a DIN-rail housing option, and can support custom variants for Large panel metering applications.
Firmware changes improve interaction of the VGA-232 with the Auto-fit features on high resolution Monitors, which do not all work the same.
VGA-232 can work with Monitors from 640x480, 800x480, 1024x768 to over 1366 x 768
The newest Monitor chipsets seem to need essentially no manual Post-Auto-fit adjust, whilst ones from 2-5 years ago can need a little.
Default model supports 38400 Baud, new models can support 115200 baud via a jumper option.
Custom serial protocols (10KBd, 12V) are also an option, for weighing system remote displays.

Common Problems:

Custom VGA ASICs, have too short a design life, and are too complex to interface to 8 bit controllers. They also require special DRAMs.
LCD Modules are OK for small, local displays, but full Graphic LCD modules rapidly escalate the cost / complexity, and they too have short design lifetimes.

The Solution: VGA-232

Our VGA-232 has been designed to use industry std components, for a long design life, and also has added features NOT found on std PC VGA systems.
An on board controller allows RS232 Serial interface, so the VGA display(s) can be placed remotely from the Host Controller.
This controller can also simply and quickly SCALE the normal 16x8 font, for improved long distance readable displays.
The VGA-232 card provides a low cost method for adding remote VGA displays, to even the smallest applications.
Unlike DOS terminal PC VGA displays, VGA-232 can easily mix scaled characters anywhere on the display area, of between 8 and 144 pixels high.
VGA-232 is an OEM product, available in qtys from 5 to 50,000+.

eANSI control

VGA-232 uses our eANSI protocol. eANSI is an enhanced version of the old ANSI 'Esc[' prefix protocol. eANSI is optimised for speed, and extended for VGA display usage, and has a 'cleaned up' state engine. Porting older sw is designed to be easy.

Shared Control

By using eANSI as a communications Protocol for any embedded uC <-> PC link, designers have the choice of any mix of PC and Vga-232 modules. PC software can parse the simple strings to extract the field information, and for low end, or simply diagnostics, you simply plug the RS232 into a VGA-232 unit.
This allows Two Feature price points, and mixed solutions can be offered to your customers: 'Factory' units operating Vga-232, and an Office Monitor running on a Windows PC.
