规格：
With selectable speeds up to 128 kbps, this line driver provides synchronous data communicati*** over 2- or 4-wire lines and, as part of a multidrop network, can support up to 64 devices.
Your data tr***els at up to 128 kbps with the BLACK BOX? RS-232/RS-485 Multipoint Line Driver (LD485S-MP) to up to 64 locati***!
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 Tran***it-clock select opti***, and delayed RTS/CTS settings.
Front-panel LEDs indicate flow-control status. And three front-panel pushbutt*** perform line and digital loopback testing.
