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 an equipment called a “HUB” or
“repeater”. It maybe necessary to have a converter between coax, T/P and the fiber cable. It is easy to design a
HUB or a repeater because the TMC2005 has various features for expanding such network.
It can connect with HYC9088 and HYC9068, RS485 transceiver, HYC2485S, HYC2488S 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.
