Easy Software Development

Communications and software development is very easy, simply write your software to speak to the RS-232 serial port (COM port of your PC), and install the included RealPort Drivers that allow you to map a COM port to an I.P. address. So you do not have to know anything about Wi-Fi 802.11b communications to speak to the device.

Many Communication Protocols for Advanced Users

Advanced users may want to employ other communication protocols to speak the the Wi-Fi 802.11b Relay Controller. NCD Wi-Fi 802.11b Relay Controllers can also be controlled using Telnet. I.P. Addresses and are automatically or manually assigned. NCD Ethernet Relay Controllers Aaso support security protocols such as Shared Key, WEP, WPA, and Cisco LEAP with support for WEP, TKIP, and CCMP Data Encryption.

Wi-Fi Relay with Analog to Digital Conversion Wi-Fi Relay with UPX Expansion Port Wi-Fi Relay with XR Expansion Port

Onboard analog to digital conversion is available on selected models of these controllers! This will allow you to:

  • Read light and temperature levels
  • Easily activate relays when A/D limits are reached
  • Detect audio levels in a room when connected to a microphone
  • Read switches, potentiometers, and analog joysticks
  • applications are limitless, and surprisingly easy to integrate
  • Available on the 4, 8, and 16 channel boards

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:

  • Add Contact Closure Inputs
  • Add Analog to Digital Inputs
  • Add Voltage Detectors
  • Digital Potentiometer Outputs
  • Available on the 4 and 8 channel boards

Models with the ProXR suffix will feature the ProXR commend set. The ProXR series will allow you to:

  • Send simple commands to activate relays
  • Upgrade without having to re-write your software
  • Activate up to 16 relay timers
  • Control up to 256 total relays using the XR expansion port
  • Full backward/forward compatibility w/the ProXR series command set
  • Available on 4, 8, and 16 channel boards
