SyncBox Master Specification

Function Description

A Clock distribution system use RJ45 wire.
It can deliver 2 clock. 
1MHz fast clock for XDAQ
1KHz slow clock for MCU
1 UART for Control Start/Stop and Reset

Generate Clock1(1MHz) Clock2(<1KHz) to remote XDaq for Sync
Suport max 16/32(??) SyncBox Slave.

Control remote XDaq through UART port to SyncBox Slave.
Such as , Reset/Start/Stop command.
And Master can tell slave staus from the UART Port.
