Product Features & Benefits

The Variable Message Sign (VMS) product range is designed to be used in conjunction with Nortech’s NCT100 and NCT200 counter modules to monitor and display count values such as the number of available spaces in a car park.

The VMS displays this information to visitors at suitable locations. Its large 4-digit, LED display panel housed in an outdoor enclosure provides clear visibility.

Up to eight VMS’s can be connected on a single RS485 bus to display different count values. The count value that a VMS displays is selected by setting an associated node number on its DIP switches. More than one VMS unit can be set to display the same count value. There is a choice of red or yellow LED colours.

The LED intensity can be set to one of four levels via the NCT100 or NCT200 module to accommodate different ambient lighting conditions.
