5.4 MON Module (Monitoring & Communication)
NOTICE!
ONLY
the master mode PCS-9785 clock source is equipped with the MON module.
The MON module consists of high-performance built-in processor, FLASH, SRAM, SDRAM,
Ethernet controller and other peripherals. Its functions include management of the complete
device, human machine interface, communication, etc.
The MON module uses the internal bus to receive data from other modules. It communicates with
the LCD module by inner RS-485 bus.
The MON module NR1110D provides two RJ45 ports and four SFP sockets. The two RJ45 ports
are used for Ethernet network (MMS communication and SNTP/NTP time message). The four
SFP sockets support the Precision Time Protocol network (IEEE 1588 protocol).
CAUTION!
