  • What type of data interface is required to communicate to serial input displays?

    Data interface includes three options: RS232, RS485 and Ethernet connections. RS232 is designed for peer to peer communication up to 100 feet away from the driving device. Standard PC's include an RS2...

  • How often do I have to change the bulbs?

    No bulb-changing is necessary! Our displays are designed with LEDS that have a life of over 10 years (100,000 hours)!...

  • How far away can LEDS be viewed?

    The viewing distance for LED displays is measured at 40-50 feet per inch of digit height. For example: 2 high text = 80-100 feet 4 high text = 160-200 feet 6 high text = 240-300 feet 8 high text = 320...
