ELSA Line Amplifier LA-101 is an amplifier/repeater for the RS485 communication cable to extend the useful data from ELSA Master Clock ES-185A to ELSA Slave Clock / RTC PC Sync. 

Timing is needed for everyone, especially for those who require the same timing system in several different places at once; Such as aerospace and defense airport, public transports, financial services, hospitals, etc.

ELSA RTC PC Sync is a slave clock software that is embedded/installed on a PC/computer with Windows operating system. So the timing of the computer system will be synchronized with the UTC timing of the NAVSTAR satellites. This can be obtained by connecting a PC that has been available software ELSA RTC PC Sync with ELSA Master Clock ES - 185A.

ELSA Slave Clock is the timing system that can be synchronized with GPS time and have many variants to the size of the display systems. ELSA Slave Clock can operate on its own and also synchronized using a Master Clock ES-185A. If the Slave Clock is receive the UTC time from Master Clock, the lock indicator will light on. And the timing will always be updated.
