Wireless portable transmitter with 4 buttons - MIDAM WKEY01
Wireless, battery operated portable transmitter featuring four digital inputs (buttons). Elegant yet robust body ensures excellent portability and manageability. Native modbus map grants seamless integration into any SCADA systems. The communication is based on encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis.
- Portable transmitter with 4 digital inputs
- Elegant and robust housing
- Excellent accuracy and controllability
- Integrated Modbus map
Function
The WKEY01 module monitors 4 digital inputs/buttons, supporting long press and flip/flop emulating (one button function). The signal is sent to a receiver, such as a wireless DALI converter (WDALIx1), wireless digital outputs (WOUT2x1), or a wireless gateway (WCOMx1). Wireless communication is based on an unlicensed 868MHz band. Embedded AES 128-bit, provides the most secure encryption standard for wireless connections. All digital inputs (buttons) are configurable. The device has factory-set values to ensure the correct default function and allows direct reading and writing of values to the Modbus map, which is available in a separate document. All settings are also stored in the Modbus map directly in the device. Before using the device for the first time, it is necessary to pair it and it is recommended to perform individual configuration, especially to change the encryption password.
Application
- 4 digital inputs/buttons with wireless module supporting long press and flip-flop (single-button emulation)
- Control of up to four light circuits or two circuits in twin mode (wireless DALI)
- Shutter and blind control
- Wireless integration into DDC/SCADA systems
- General-purpose use
Pairing
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Usually, wireless gateway or configuration dongle is used to set up remote wireless devices. Use look-up function in software tool to display a list of all available devices in range and assign or adjust parameters based on wireless ID code for each single device. There is a comprehensive help section integrated in the software tool to provide support during the wireless device set up procedure. To perform manual pairing, set the PRG switch or the DIP switch on the remote device. From this time on, any digital input (button) on WKEY01 must be activated within 10 seconds. This confirms the pairing of both devices. Switch the PRG DIP switchs on remote device again.
SCADA system integration
For direct integration of the device, use of wireless gateways, such as WCOM01, or WCOM51 is recommended.
Midam KFP Password change
Prior to the first use, the encryption password (default “MIKROKLIMA1234AB”) must be changed using the WUSB01 configuration dongle and the relevant software tool.
