Hi*Tech manufactures a standard LED electronic display sign that is rugged, reliable, and cost effective for your in-car use. The electronic display sign can be custom mounted in a variety of locations inside a rail car or bus. Although there are two displays that are our standard, we can custom build nearly any type of LED electronic display sign for use inside your bus or train. International characters, bold-faced and double-high fonts, graphics, flashing neon light, scrolling and sequencing of the message are all standard features of these signs. Programming and controlling the signs can be made via an RS232 or networked through an RS485/422 interface.
