UTNH23B Optical shared hub unit
UTNH23B 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.
