تبدیل شبکه RS485 به USB و برعکس U-485

اطلاعات فنی بیشتر:

1, Applies to all USB ports on PC. Support U-485 operating system: Win98/2K/XP; MAC OS-9/X;

Linux 2.40 and above

2, USB port-powered, no external power, the current <50 mA

3, Output for the second-line Connection-half-duplex RS485 interfaces

4, Use the shielded twisted pair whose sectional area is over 0.5 mm2 as communication lines

5, The largest communications distance is 3,000 meters (4800 bps), 2000 m (9600 bps) and

1000m(115.2Kbps).

6, Group website is at least 32 points. For the most points of the group website site is depend on

the input impedance of RS485.

7, Communications rate of 300 bps ~ 1Mbps, standard baud rate adaptive

8, Support for UART data format: data bits: 7-8, stop bit: 1, 2, check-bit: odd / even / no parity

9, A transient voltage suppression, RS485/422 port can withstand the transient over-voltage

whose power is up to 600 W and electrostatic discharge and lighting strikes impact

10, The working temperature: -20 ~ 70C
