DPM4 Low Cost Panel Meters by Versalent Home
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||
General Description
The DPM4 digital panel meter system provides one to four 4-digit LED panel meters. The optional meters are tethered to the Control Unit with a ribbon cable up to 18 feet long and each includes its own panel-mount bezel for any physical arrangement of meters. Signal and power wiring all connect to the Control Unit only. Meters can be configured for differential operation and each offers 19 different input range options. The programmable 8-decimal-digit scaling factors eliminate the need for analog pot adjustments. Programmable scaling and offset allows the meters to convert ANY available input range to ANY display range from -9999 to +9999 with decimal points automatically placed as needed. The Configurator application requires just a few simple entries to generate and download the scaling factors. And the configuration can be dynamically changed to alter the scaling from lbs and kilos, nanometers to microns etc. in an instant through the RS232 command port allowing a host to be hundreds of feet away. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
Advantages Over Conventional Panel Meters

Detailed Description Each of the up-to-4 independent meters provides 0.36" high red 7-segment LED digits. Once configured the DPM4 can operate autonomously, or can be dynamically reprogrammed to change scaling, or even display text messages provided by a remote host via RS232. Can be ordered with 2 or 4 analog channels and up to 3 additional (tethered) displays. The channels can be configured as separate or differential (CHX - CHY measurements). The wide-ranging flexibility of multiple analog signals, multiple displays, selectable mapping between them, and so many available hardware ranges requires an organizing application to manage. Plus the calculation of scaling and offset factors would be difficult without automated help. The Versalent Configurator is a Windows application that generates all the scaling factors and display mappings. User input is reduced to entering a few simple values: (for each channel) a signal input range: low-value, and high value such as 0.0V and 4.00V . And the desired meter readings associated with these inputs such as 100 and 9000. The configurator computes and downloads the factors to make your display do it!. A simple checkbox grid allows mapping the channels to displays. A host can issue RS232 commands to alter the scaling/display-mappings dynamically. The Configurator can generate alternate scaling/mappings to change the display from lbs to kilograms for instance. The alternate configurations can be stored in your host and sent to the DPM4 whenever the display requires re-scaling, or meters need to switch positions. Configuration messages are short and a meter can completely change its operation in a few milliseconds. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
