NETCLOCK/2™ INTERFACE OPTION

6.1OVERVIEW

A Coordinated Universal Time (UTC) standard option is available that allows the CEC/IMC to be synchronized to WWVB, operating on a frequency of 60 kHz, in Fort Collins, Colorado. This option uses Spectracom® Corporation's NETCLOCK/2™ WWVB receiver which interfaces to the CEC/IMC via an RS-232 serial port at the CEC/IMC Manager (usually COM2). With this option installed, the CIMs and consoles are synchronized to the UTC signals broadcast by WWVB.

NOTE

NETCLOCK/2 functions are now integrated into the Microsoft Windows NT operating system. Previously, NETCLOCK/2 functions were integrated into CEC/IMC Manager software program V4.0. The option was a Terminate Stay Resident (TSR) program in software versions prior to V3.0 (V2.12 and earlier).
