Variable Message Signs

Product Description

The DPX-400 is used to control all aspects of a Variable Message Sign (VMS) using 3G/4G, Ethernet, ISM or Zigbee secure links. A wireless bridge is established between existing serial EIA-232 or EIA-485 systems by the DPX-400.

The system is designed so that a second DPX-400 can be placed at the central site.
