ADDITIONAL SYNCHRONIZATION:
NONE - Clock does not have additional synchronization
485 - Serial data transmission between devices over a two-wire line. If a master synchronization is used, e.g. GPS, the 485 is set to transmit (MASTER) the time protocol. If master synchronization is not used, 485 is in ready mode (SLAVE) ready for reception. A device in “MASTER” mode can be connected to several devices in “SLAVE” mode. They then have time synchronized according to "MASTRA". The protocol also allows to transmit temperature data.
DHF BUILT - Serial wireless data transmission. If master synchronization is used, the direction is set to broadcast (MASTER) the time protocol. If no main synchronization is used, the clock in the input mode (SLAVE) is ready for reception. A device in “MASTER” mode can be connected to several devices in “SLAVE” mode. They then have time synchronized according to "MASTRA". The protocol also allows to transmit temperature data.
NTP - connector for synchronization from NTP server in ethernet network. Once connected to the network, the addresses of two servers can be set via the web interface. The clock will then sync from the listed servers. NTP server you can have your own or use some of the servers on the Internet.
OPTIONAL EQUIPMENT:
SIREN WITHOUT SIREN - The clock does not have piezo-sulfur.
WITH SIREN - Part of the clock is a siren with a constant tone. The clock can be programmed to sound the siren at nine programmed times. Used to report breaks.
