Host computer communicates with the monitor unit and the protection unit of LCUs through the CAN bus. PLC in LCU communicates with host computer through the RS-485 port.
主控计算机与各lcu中的监控单元和保护单元通过CAN总线通信，LCU中的PLC通过RS- 485接口与主控计算机通信。
The only disadvantage of the design is that at the two smallest field sizes (5 and 7.5 mm), the dose delivered per monitor unit is substantially lower than that attainable with a fixed collimator.
然而这种设计唯一的缺陷是对于2个最小的射野大小(5毫米和7.5毫米)，每个机器跳数传输的剂量基本上是低于固定准直器的。
