UTNH23A Optical shared hub unit
UTNH23A用于信息和控制网络TC-net 100的光共享集线器单元UTNH系列构成了TC-net 100光传输线路。它采用了一个有8个端口的MT-RJ光学连接器。集线器单元还有一个用于RJ-45模块连接器的端口，它可以连接到TC-net 100(双绞线)设备。在使用单个单元时，对线路A传输线UTNH23A(为TC-net 100安装的SNMP)使用光学共享集线器单元，或对线路B传输线UTNH23B使用光学共享集线器单元-UTNH23A Optical shared Hub Unit for information and control network TC-net 100 The UTNH series constitutes the TC-net 100 optical transmission line. It uses an MT-RJ optical connector with eight ports. The hub unit also has a port for the RJ-45 module connector, which can be connected to TC-net 100(twisted pair) devices. When using A single unit, use an optical shared hub unit for line A transmission line UTNH23A(SNMP installed for TC-net 100) or for line B transmission line UTNH23B.
The information and control network TC-net 100 has the following characteristics.
• Open
TC-net 100 is a monitoring network with the open characteristics of 100mbps Ethernet, collision avoidance capabilities and deterministic time response.
• Communication services
The communication service includes scanning transmission (circular broadcast sending and receiving) and ordinary message transmission that periodically control data transmission.
There are three modes of scan transmission: high speed mode, medium speed mode and low speed mode. These patterns can be assigned according to data refresh cycles to ensure real-time response later on.
• Message transmission supports not only TCP, UDP and IP, but also Toshiba standard protocol PCMP.
• High reliability
Dual transmission line configurations build highly reliable systems. Electro-optical transmission line is optional.
