The Microframe Model 240, 4-digit Remote Display, is designed to operate with any standard RS232, RS485, or 20 mA current loop input to provide Remote Display capabilities for a computer, PLC, or scale display. The Model 240 Display contains Ultra-bright LEDs configured in 5.5-inch tall digits viewable up to 125 feet and is encased in an extruded aluminum case.
Operation
The computer passes numbers and a carriage return (ASCII 13D), and the numbers will be displayed on the Model 240. Pass a carriage return to display a blank screen (ASCII 13D). Insert the decimal point in the number string, and it will light. Include a colon in the number string to light the colon for that number. Leading zeros will be blanked if the user-selectable option is enabled.
Microframe's 200 Series displays will show positive and negative integers. The 240, 4-digit display will show a negative symbol. However, the negative symbol replaces the first digit, leaving only three integers. Example: Positive [1234] or Negative [-123]
