Introduction Thank you for choosing the PLASTIC-PALM 10BASE-T Ethernet Hub. The hub was designed and manufactured to give you years of trouble-free and reliable service. The hub is designed for plug-and-play installation and easy management. The hub provides an Uplink connection for your network expansion via a RJ-45 connector, making it easy to link two or more hubs together. The hub features LINK/RX LEDs to show the connection and receive status of each twisted pair port. PWR and COL indica

9-port Ethernet Hub with BNC port 17-port Ethernet Hub with BNC port LED Indicators Power (PWR): This indicator lights green when the hub is receiving power, otherwise, it is off. Collision (COL): This indicator indicates data collisions on the respective Ethernet segments of the hub. Whenever a collision is detected, the respective COL indicator will briefly blink amber. Link/Receive: This indicator green when the port is (LINK/RX) connected to a Ethernet station , If the 4

station to which the hub is connected is powered off, or if there is a problem with the link, the LED will remain off. And the indicator blinking green when the data will be received to all other connected ports. BNC: This indicator blinking green when the data is transmitted. Rear Panel Indicators Twisted-pair Jacks Use these jacks connect stations to the hub. These are MDI-X (Medium Dependent Interface, Cross-Wired) jacks, which means you can use ordinary stright-through twisted-pair cables t

Installation Installing the Hub The site where you install the hub may greatly affect its performance. When installing, consider the following pointers: Install the hub in a fairly cool and dry place, for the acceptable temperature and humidity operating ranges. Install the hub in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. Leave at least 10 cm of space at the front and rear of the hub for ventilation. Install the

Crossover Cables When making an uplink connection between one hub and another (or between a hub and a switch or bridge) using X -type jacks at both ends, you must use a crossover cable. In a crossover cable, two pairs of wires are switched at one end. Carry out the following steps to create a crossover twisted-pair cable: 1. Leave one end of the cable as-is, with the wiring on the RJ-45 connector unchanged. The wiring needs to be modified at one end only. 2. At the other end of the cable, conne
