控制集线器
从这里你可以控制集线器。您可以启用和禁用安装的任何变送器，设置检测模式并选择旁路模式条件。单击通信按钮， 主屏幕警告：仅更改传输控制、旁路控制和检测模式列中的值不会执行更改。单击“更新”按钮提交更改并刷新状态。Ethernet GUI显示的状态屏幕不会自动更新。您必须单击“更新”按钮才能查看当前状态。Artisan Technology Group-优质仪器…保证|（888）88-SOURCE | 操作软件描述1检测模式选项信号丢失（LOS）每个小型可插拔收发器模块都有一个LOS信号，当SFP收发器模块未能在正常光谱工作范围内检测到足够的光时，该LOS信号变高（1）。对于反射式存储器，惯例是将该信号视为信号检测（不是）而不是信号丢失，因此每个SFP的LOS被反转并显示在以太网控制和状态屏幕的信号检测列中。标记为SD的每个端口附近的黄色LED也对应于信号检测。单和多同步每个端口接收器包含检测网络同步模式K28.5在大约15.5µsec的每个周期内发生的电路。
K28.5同步模式出现在所有网络分组之间，并在网络空闲时重复出现。此外，该电路检查输入数据流是否存在有效的运行差异（每个模式中正确的零（0）和一（1）数量），这是可靠操作所必需的。有效同步和有效运行差异的组合需要构成“真”条件。如果检测模式控件设置为单同步设置，则根据此“真”条件的状态，相关端口的同步检测位将每隔15.5µ秒设置或重置一次。如果检测模式控件设置为多同步设置，则端口同步检测位的状态将仅在连续出现四个“有效”或“无效”时段时发生变化。在连续出现四个“有效”或“无效”周期之前，端口同步检测信号的状态将保持不变。当在旁路控制选项中选择了自动模式，并且选择了单同步或多同步设置时，如果出现相应的无效情况，端口将被旁路。由于硬件限制，检测模式（LOS、单同步或多同步）的设置在端口对中完成。这对是端口0和1、端口2和3、端口4和5以及端口6和7。更改对中一个端口的检测模式也会更改对中另一端口的检测方式。
Control hub
From here you can control the hub. You can enable and disable any transmitter installed, set the detection mode, and select bypass mode conditions. Click the communication button, and the main screen warns that changing only the values in the Transmission Control, Bypass Control and Detection Mode columns will not be performed. Click the Update button to commit the changes and refresh the status. The status screen displayed by the Ethernet GUI is not automatically updated. You must click the Update button to view the current status. Artisan Technology Group - High quality instrument... Guarantee | (888) 88-SOURCE | Description of operating software 1 Detection mode option Loss of signal (LOS) Each small pluggable transceiver module has a LOS signal. When the SFP transceiver module fails to detect enough light within the normal spectral operating range, the LOS signal becomes higher (1). For reflective memory, the convention is to treat this signal as signal detection (not) rather than signal loss, so the LOS of each SFP is reversed and displayed in the signal detection column of the Ethernet control and status screen. The yellow LED near each port labeled SD also corresponds to signal detection. Each port receiver of single and multiple synchronization includes a circuit that detects that the network synchronization mode K28.5 occurs in each cycle of about 15.5 µ sec.
K28.5 synchronization mode appears between all network packets and repeats when the network is idle. In addition, the circuit checks the input data stream for valid operational differences (the correct number of zeros (0) and one (1) in each mode), which is necessary for reliable operation. The combination of effective synchronization and effective operational differences requires a "true" condition. If the detection mode control is set to single synchronization setting, the synchronization detection bit of the relevant port will be set or reset every 15.5 µ s according to the status of this "true" condition. If the detection mode control is set to the multi synchronization setting, the status of the port synchronization detection bit will only change when four consecutive "valid" or "invalid" periods occur. The status of the port synchronization detection signal will remain unchanged until four consecutive "valid" or "invalid" cycles occur. When the automatic mode is selected in the bypass control options and the single synchronization or multi synchronization settings are selected, the port will be bypassed in case of corresponding invalidity. Due to hardware limitations, the detection mode (LOS, single synchronization or multi synchronization) is set in the port pair. This pair is ports 0 and 1, ports 2 and 3, ports 4 and 5, and ports 6 and 7. Changing the detection mode of one port in the will also change the detection mode of the other port in the.
