(1)Transceiver

A transceiver converts signals flowing through coaxial cables (yellow cables) into signals that the nodes can use, and vise-versa.

When you want to connect a transceiver, it should be installed at a distance of 2.5 m (or a multiple of 2.5 m) from any other transceiver. Coaxial cables are marked at 2.5 m intervals. That makes it easy to install the transceiver over one of these marks on the cable.

Before connecting a transceiver to a coaxial cable, shut OFF the power supplies for the nodes and transceivers. If you make a connection while the power is still on, you may cause a short circuit. Use transceivers that conform to the IEEE802.3 standard.
