The new Unified Host Interface provides both an RS-232 or
RS-485 interface port (only 1 can be used) that is jumper
selectable.
This 8-port expansion hub is used to distribute RS-485 signals
and power to devices located up to 4000 ft away. Because RS-485 signals travel farther along the line, you can run
dedicated cable without having to purchase expensive repeaters, couplers,
amplifiers. You'll also save money by reducing the amount of wiring used,
since devices connected to the RS-485 line can be daisy chained, instead of home
run.
Each channel has a separate RS-485
driver, which can transmit signals along 4,000 ft. of cable on each channel.
Other features include 2-wire half-duplex operation and 4-wire screw terminal
strips (2 power, 2 data). The unit also offers such optional features as a
two-way RS-232/485 converter and 16-device configuration.
