Description
The NSM-108 has 8 Ethernet Switching ports that support 10/100Base-T(X), with a 10/100M auto-negotiation feature and auto MDI/MDIX function.
It can connect 8 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections.
The flow control mechanism is also negotiated. There is link/data rate LEDs for each port to aid trouble-shooting. Port connectors are shielded RJ-45.
This unit is supplied in an IP20 rugged, high-strength steel case capable of either DIN-Rail or Wall Mounting.
Features
- Automatic MDI / MDI-X crossover for plug-and-play
- Each port supports both 10/100 Mbps speed auto negotiation
- Store-and-forward architecture
- Full duplex IEEE 802.3x and half duplex backpressure flow control
- 2 Gbps high performance memory bandwidth.
- Supports +10 ~ +30Vdc voltage
- Supports operating temperatures from -30 ~ +75°C
- IP20 rugged hugh-strength metal case
- DIN rail mount for industrial usage and screw hole for wall mounting
