Essential details：UTNH23A Optical Shared Hub Unit TOSHIBA
Features of Optical Shared Hub Units
TC-net 100 is a monitor and control LAN for the Integrated Controllers, which can be configured using optical fiber transmission lines and twisted-pair cable transmission lines. The optical shared hub unit is necessary for configuring optical fiber transmission lines, and connects TC-net 100 stations to the network.
The UTNH23A, which has SNMP for TC-net 100 mounted in it, permits diagnosis of the ports connected to the optical shared hub unit.
The standard TC-net 100 has dual transmission lines, of which line A is for connecting UTNH23A and line B for connecting UTNH23B.
The information and control network TC-net 100 has the following features.
• Open The TC-net 100 is a monitor and control network featuring the open characteristic of the 100-Mbps Ethernet, collision averting function, and definitive time response.
• Communication service Communication service covers scan transmission (cyclic broadcast transmission and reception) for periodic control data transmission and ordinary message transmission.
• Scan transmission has three modes: High-speed mode, medium-speed mode, and low-speed mode. These modes can be assigned according to the data refreshing cycle to assure definitive real-time response.
• Message transmission is supported by not only TCP, UDP, and IP but also the Toshiba standard protocol PCMP.
• High reliability
High-reliability systems can be built by dual transmission line configuration. Electric or optical transmission lines can be selected.
UTNH23A
• AC connector
Power is supplied through this connector to the optical shared hub unit.The input voltage range is wide from 95 VAC to 250 VAC. A power supply sufficient for the power consumption of 0.6 A/100 VAC must be ready. The connector has a built-in fuse, which becomes broken by an overcurrent to shut off power supply. A burnt fuse must be replaced with a new one (250 V, 3 A, UL compliant). It is recommended that the fuse be periodically replaced even if it is not broken. (Refer to 6.3 Expendable Parts.) Use the shielded power cable supplied with the hub unit.
• RJ45 modular connector (TX-0)
This is an electric 8-pin modular connector for TC-net 100. Connect it to a station having an electrical interface with an enhanced category 5 twisted-pair straight cable. Connect to the optical shared hub unit, having an electrical interface with an enhanced category 5 twisted-pair cross cable.
• MT-RJ optical connectors (FX-1 to FX-8)
These are MT-RJ optical connectors for TC-net 100. Connect them to stations having an optical interface with optical fiber cords (GI quartz 62.5/125) with an MT-RJ connector.
• Connector for line A/B SNMP (DUAL)
This is an SNMP data communication connector for TC-net 100. It is used to connect dual hub units UTNH23A and UTNH23B to each other with the enhanced category 5 twisted-pair cross cable that is supplied with the UTNH23B.
• Ethernet connector (MENT)
This is an SNMP communication port. Connect it to a 100BASE-TX Ethernet card with an optional enhanced category 5 twisted-pair straight cable (one-to-one connection only) for communication with TC-net 100 stations.
