The VT500 Video Time-Date Generator & Video Stop Watch (Video Timer) from MicroImage Video Systems can display a real time clock on screen and it can also operate as a full function stop watch with various timing modes and remote capabilities.

The VT500 is a high performance multipurpose video timer. The display can be customized to fit most common time and date display standards throughout the world. The unit will keep time, even during extended periods without power. The VT500 has a five year (typical) internal battery life (the battery can be replaced when needed).

The display of the time/date can be adjusted to suit many tastes with several hundred different display combinations. The time can be displayed in 12 or 24 hour mode with AM/PM display optional. Seconds may be turned on or off. The date format may be month followed by day or day followed by month and the month can be displayed as a number or three character word. The century and day of week may individually be displayed or suppressed.

The time/date/stop clock display can be moved anywhere within the active display area of the screen and can be set to one of many colors. A color background can optionally be displayed behind the characters. Character size is relatively small (unobtrusive) yet very crisp and can be easily read during tape playback, even on poor quality recordings. The VT500 is designed to support B&W, composite and S-Video (YC) signals.

Stop watch display accuracy is selectable and can be set as precise as 1/1,000 second. Maximum count time is 99 hours, 59 minutes and 59.999 seconds (99:59:59.999). As a stand alone unit (remote control not used), the VT500 can act as a simple timer or stop clock. Using the front panel switches, the clock may be stopped, started, reset and the display can be frozen while continuing to count. Several modes of split timing are available.

The stop watch capabilities of the VT500 can be realized by using the external control inputs. These inputs are designed to interface easily to logic levels (3V or 5V), switches, relays, or virtually any other type of contact closure. Each input can be programmed for normal or inverted logic or have a digital noise filter applied as well. When the external inputs are used, the resolution of the VT300 can be as precise as 1/1,000 second.

The timer/date/counter overlay may be turned on or off at any time, without affecting the clock or count, simply by pressing the display switch on the front panel. Turning off the display switch allows the video signal from the source (such as a camera) to pass through but it does not display the time / stop clock image on the screen. The time display can be easily positioned virtually anywhere on the screen via the front panel switches. Options are set through an easy to use, on screen menu system and reside in nonvolatile memory when power is off.

The VT500 can be powered from a +12VDC, negative ground power source. A Universal 120-230V power supply is included with cased units. For OEM applications, MicroImage Video Systems can provide board level product or private labeling. The VT500 has a one year parts and labor limited warranty.

A Rack mounting kit is available as an option.
