General Description
When configuring a network, the maximum number of nodes and the maximum cable length are limited by the electric capacity of the transceiver. In this case, the network is expanded by a piece of equipment called a "HUB" or "repeater". It may be necessary to have a converter between coax, T/P and the fiber cable. It is easy to design a HUB or repeater because the TMC2005 has various features for expanding such a network.
It can connect with HYC9088, RS485 transceiver, HYC5000/4000/2000 and TTL interface for optical module. It can connect with three different transceivers at the same time and convert the media of each. (The data rate cannot be converted. It is necessary to operate all nodes in the same network at the same data rate.) The Hubs can be expanded by connecting two or more TMC2005 chips. By setting one of 5 ports to open-drain output, the Hub can be expanded to either 12 or 16 ports.
