EI813F电子模件,EI813F中文说明
支持每个通道都有指示灯发送和接收活动的状态。
RJ-45插孔已金属化接地外壳。应使用屏蔽电缆，屏蔽连接到金属化接头壳体。
RS-232通信板CI271板是一个可选接口配有两个RJ-45插孔，用于RS-232通道，每个都配有全套调制解调器控制信号。可安装两块CI271板在AC 800C中。以太网通信板CI272板是一个可选接口带一个用于以太网10Base-T的RJ-45插孔（双绞线，最大电缆长度100 m）。
EI813F电子模件IP地址通过控件输入建筑商M.可使用两块CI272板安装在AC 800C中。冗余网络可以进行布线。
电池/实时时钟板SB210是AC 800C的可选板它包含一个锂电池和一个实时时钟。电池为实时时钟供电并保存公羊至少一年。实时时钟（RTC）跟踪电源故障的持续时间。
如果没有SB210，RAM内容可能是通电约20分钟后丢失失败应在以下时间更换蓄电池每年至少一次，或电池电量不足时电压由闪烁的PWR指示
指示电池可以更换操作期间。
support. Each channel has LEDs indicating the status of transmit and receive activities. The RJ-45 jacks have metallized grounded housings. A shielded cable should be used, with the shield connected to the metallized housing of the connector. RS-232 communication board The CI271 board is an optional interface with two RJ-45 jacks for RS-232 channels, each with a full set of modem control signals. Two CI271 boards can be installed in AC 800C. Ethernet communication board The CI272 board is an optional interface with one RJ-45 jack for Ethernet 10Base-T (twisted pair, max. cable length 100 m). The IP address is entered via Control Builder M. Two CI272 boards can be installed in AC 800C. Redundant network routing is possible. Battery/real-time clock board SB210 is an optional board for AC 800C which contains a lithium battery and a realtime clock. The battery supplies the real-time clock with power and preserves the contents of the RAM for at least one year. The realtime clock (RTC) keeps track of the duration of a power failure. Without SB210, the RAM contents may be lost after about 20 minutes of power failure. The battery should be replaced at least once a year, or when low battery voltage is indicated by a flashing PWR indication. The battery can be replaced during operation.
