|
| ||
| Module / Integral Controller | The on-board dedicated microcontroller, which acts as an interface between the CPU and the row and column drivers. The controller takes care of generating characters, refreshing the display, etc. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Serial Interface Option | Display has a serial interface such as RS232, USB, etc. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Electro Luminescent Backlight | VFDs do not require backlighting but some offer it as an option. Usable in all lighting conditions. A kind of lamp that gives off a cool glow, powered by hi-voltage, high-frequency AC from a DC-AC inverter. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Fluorescent Backlight | VFDs do not require backlighting but some offer it as an option. Not usable in high ambient light conditions. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Keypad Interface | Has a keyboard to interface with the module. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| RoHS | Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
