MDN49 Multi-Network Digital Display

The MDN multi-functional digital display syncs to an internal or external NTP (Network Time Protocol) source for accurate, USNO legally traceable time. Alternatively, the MDN can be remotely programmed to sync to and display IRIG B or choose to auto detect and display varieties of IRIG analog (CS3) and digital (CS5) countdown time codes or planned times that can be received by cable or from an almost unlimited choice of counts available by Ethernet by using Masterclock CS5 Ethernet injectors.
