CS5-LAN Network Injector

Masterclock's CS5-LAN network injector is a compact, precision time and frequency translator for a wide range of applications in the commercial, industrial, military and laboratory environment. One compact unit can read CS5246 countdown code as defined in the Range Commanders Council ‘s IRIG 215-12, with mission character and planned/actual times and broadcast the CS5 packets by Ethernet to NTP multiple clocks on the network while using only approximately 1K of the Ethernet bandwidth. Using additional CS5 injectors, almost unlimited numbers of counts can be transmitted on the Ethernet.
