LEMOS INTERNATIONAL CO. INC. releases the Lemos / Sena Industrial Bluetooth Headset

Tuesday, October 17th, 2017

The Lemos / Sena Tufftalk is the first fully Bluetooth integrated intercom device to both protect the user and supply a clearer communication channel. This device marks our continued commitment to the safety and efficiency of the industrial field.”

The Lemos / Sena Tufftalk,is an earmuff Bluetooth® communication and intercom headset, and is designed specifically to meet the communication and connectivity needs of industrial applications. Tufftalk sports a 1.4 km working Bluetooth range – the furthest of any product on the market today. Its sturdy design and tough manufacturing offers up to 15 hours of uninterrupted intercom communication between up to four headsets. Coupled with its seamless compatibility with other Bluetooth and two-way radio devices, including SENA SR10i which allows for wireless two-way radio communication, Tufftalk far outpaces the competition.

Breaking through the noise

In rough and loud environments, safety is key, and this is exactly where Tufftalk truly shines. Tufftalk’s secure earmuffs help protect users from harmful noise with an audio attenuation of 24dB. The ambient mode feature allows users to amplify external sounds – generating greater awareness of surroundings so important alarms or calls can be heard while still protecting hearing. For more active applications, Tufftalk offers an optional hard hat mount package.

“Poor worksite communication is costly for businesses,” Kim said. “With Tufftalk we applied Sena’s two decades of expertise to offer industrial strength seamless communication for the harshest of environments.”

Equipped with HD quality speakers, Tufftalk delivers crystal clear audio that industrial mobile workers need to stay safe on busy and noisy worksites. Tufftalk features Sena’s Advanced Noise-Control™ technology, which limits the interference of background noise while maintaining the full volume of voice communication.

Sena’s patented Jog Dial design is glove-friendly and easy to control, while the VOX technology allows users to answer phone calls, communicate and react to voice commands, all while hands-free. Tufftalk is also compatible with a Sena App to configure settings and presets easily through any smartphone. As with all Sena units, Tufftalk is completely firmware upgradeable to ensure it remains compatible with all of the latest Bluetooth technology.

Multiple Connection Mode feature of Parani-SD1000 & Parani-ESD products

Wednesday, June 30th, 2010
As you may know, one of the competitive-edge features of Parani-SD1000 and Parani-ESD (ESD1000, ESD100v2 and ESD110v2) Bluetooth products is that; they support multiple connection mode feature.

Now that; we have released a software utility, “Parani Multi Wizard”, that allows configuration of multiple connection mode feature.  In the space below, let me summarize you about multiple connection mode feature and “Parani Multi Wizard”, for your reference.

Multiple connection mode:

With multiple-connection feature, one Sena Bluetooth adapter (let’s say Parani-SD1000) master unit can connect up to 4 Parani-SD1000 slave units simultaneously. There are two different multiple-connections modes available:

– Multi-Drop Mode

One master and up to 4 slaves can communicate with one another simultaneously in both direction.

– Node Switching Mode

Up to 4 slaves remain connected to the master, but only one slave communicates with the master at a time. The master selects which slave unit to communicate with using AT commands.

For detailed information about multiple connection mode, please see the attached presentation (1.2 mb / PPT) or following web locations:

Multiple connection mode configuration using Parani Multi Wizard:

The “Parani Multi Wizard” is the software tool for the configuration of multiple connection mode of Parani-SD1000 and Parani-ESD (ESD1000, ESD100v2, and ESD110v2) products.

The “Parani Multi Wizard” supports a couple of modes.  (1)  Wizard mode (2) Manual mode.  The Wizard mode provides the user, step-by-step instructions for multiple connection mode configurations.  In the Manual mode, settings for the multiple connection mode are to be entered manally, but can be configured in one window.
