1. Introduction
The NS-205R has 5 Ethernet Switching ports that support 10/100Base-T(X),
with a 10/100M auto-negotiation feature and auto MDI/MDI-X function. It
can connect 5 workstations and automatically switches the transmission
speed (10 Mbps or 100 Mbps) for corresponding connections. The flow
control mechanism is also negotiated. LEDs embedded in RJ-45 jacks
make for easy monitoring. Port connectors are shielded RJ-45. A power
source for +10 ~ +30VDC is required.
