This 8-port expansion hub uses the RS-485 protocol, which is not only more
powerful than the RS-232 protocol, but is also easier and more affordable to
install. 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. Unit can be purchased
as either an RS232 or RS485 host interface. Dimensions are 6" x 4" x
1.5". A 12V power supply is included.
