Ultra-Long Range Transmission: Achieves ultra-stable 2.4G DSSS wireless communication, with a transmission distance of up to 2 kilometers, perfectly avoiding the complicated wiring constraints in super large factories.
Zero Packet Loss Architecture: Ideal for real time data streams. It provides a full-duplex, error-free communication channel without packet loss, stalling or data corruption (up to 38400 bps).
Flexible Mesh & Star Topologies: adaptable to any facility layout. It supports point-to-point, star and peer-to-peer mesh networking with up to 65,535 user-definable network IDs and 16 independent channels to eliminate crosstalk.
Universal Serial Bridging: acts as a true transparent serial bridge. Effortlessly integrates RS232, RS485 and RS422 legacy instruments into a single wireless network with no changes to your existing PLC code.
A: The device has a dedicated hardware “Config” switch (DIP switch). Simply switch the device into configuration mode and connect it to your PC using a standard RS232 or USB-to-RS485 adapter. Then you can easily configure your operating modes, channels and baud rates using our free Zigbee Configuration Tool for Windows.
Q: Nah. The VT-ZIGBEE700 employs advanced DSSS (Direct Sequence Spread Spectrum) technology and 16 selectable independent channels, even though it operates in the 2.4GHz band. Pick a channel that does not overlap with the frequencies your local Wi-Fi is using and you are guaranteed no cross-talk and perfect data integrity.
A: Yeah. You can easily configure a Point-to-Multipoint (Star) or Mesh topology by setting up one node as the “Center Node” (Master) and the other nodes as remote nodes. The polling requests of the PLC will be transparently broadcasted by the master node and the addressed slave node will reply, emulating a traditional wired RS485 daisy-chain over the air.
