Extend sync RS-232/485 data beyond the 50 ft limitation over CATx at data rates up to 128 kbps and reach distances up to 4 miles in point to point or multipoint environments.
With selectable speeds up to 128 kbps, this line driver provides synchronous data communications over 2- or 4-wire lines and, as part of a multidrop network, can support up to 64 devices.
Your data travels at up to 128 kbps with the BLACK BOX® RS-232/RS-485 Multipoint Line Driver (LD485S-MP) to up to 64 locations!
With its RS-485 line interface, this driver delivers reliable signals, even in the most demanding shop environments - conveyor belts, time clocks, and more.
And the LD485S-MP is just as reliable in tail circuits, too. You get less jitter in Receive clocking, a range of Transmit-clock select options, and delayed RTS/CTS settings.
Front-panel LEDs indicate flow-control status. And three front-panel pushbuttons perform line and digital loopback testing.
Choose a standalone model or a rackmount card. Use the card with our 16-Card Interface Converter Rack (RM005).
