数据信号传输采用一对一寻址的RS - 485总线传输，造成工程开工布线和工程完工后的拆卸工作繁重，甚至可能引起仪器损坏。
Data acquisition signals are communicated with RS485 bus point to point. As a result, installation and disassembly of instruments become heavy loads, and instruments may be damaged easily.
它会修谈到无限信号并且会显示找到的任何在公共无线网络里传输的数据。
It sniffs the airwaves and displays whatever data it finds being transmitted in the public hot spot.
它们通过光纤飞速传输，几乎不丢失数据也不被其他东西干扰（这就是为什么不同的信号可以在同一根光纤中传输以倍乘它的容量）。
They whizz through optical fibres, rarely getting lost or interfering with one another (which is why different coloured signals can be sent down a single fibre, to multiply its capacity).
