Communications Devices

Cansec manufactures a variety of RS-485 communications devices ranging from USB and network to wireless RS-485 devices. These options provide dealers the flexibility to choose a communications device that best fits the project requirements.

RS-485 Wireless CommunicationIntroducing a wireless RS-485 communications device that is compatible with most 2-wire RS-485 products on the market. The perfect solution for those installations where wired connections are cost prohibitive. Configured using simple DIP switch settings. Air-485TM has a built-in signal strength indicator to assist you in a quick and easy installation. Air-485TM supports Point-to-Point and Point-to-Multipoint network topologies with incredible ranges and reliability.

One of the biggest challenges in setting up a wireless system is determining the optimum placement of the RF modems to obtain the right balance of range and signal strength. The Air-485TM RF modem contains three LEDs which provide a simple visual indication of signal strength. No meters or other equipment are required for the installation. Because the Air-485TM  modems are totally separate from the wired or wireless LAN, there is no need to configure complex network parameters or involve any IT departments.
