The
HUB-485-4 is an industrial-grade (wide temperature range with surge & static protection) optically-isolated RS-485 Hub/Splitter/Repeater, which can be used to expand RS-485 networks by splitting one RS-485 network into four, in turn increasing the maximum number of nodes and the distance covered by an RS-485 network. The unit comes with options for RS-485 or RS-232 input, for easy installation. It was designed so that data coming from the input (RS-232 or RS-485) will transmit to all four loops of RS-485 networks. However, each loop of RS-485 devices will transmit data back to the input only, thus reducing any possible interference between each loop of the RS-485 devices. Also, the failure of any individual loop will not affect other loops, making the RS-485 networks more robust and reliable.
The product features opto-isolation circuitry, which effectively protects your RS-232/RS-485 devices from transient surges, ground loops and spikes. Opto-isolation also eliminates ground loop and noise problems. The unit supports data rates up to 115,200 bps and features data format auto-sensing and self-adjusting; therefore, no DIP switch or jumpers are required.
