HME DX121

The HME DX121 system is comprised of the BS121 base station, BP200 beltpack or WH200 wireless headset, and compatible headsets. The DX121 supports 1 full-duplex or 4 push-to-transmit shared beltpacks, while providing interface option to 4-wire intercom systems only. It is a highly portable and versatile system that can be plugged directly into the headset jack of any intercom station or into a four-wire connection of a device such as a digital matrix intercom. The 2.4 GHz frequency-hopping, Spectrum Friendly technology allows up to eight DX121's to be used together to support multiple channel applications. The DX121 can be used to support wireless channels for theatrical and live crew events, broadcast control room operators, technical support crews and for connecting remote staff at large venues.

ETSI Compatibility as of January 1, 2015

The European Telecommunications Standards Institute (ETSI) has mandated a change in the way wireless products operate in the 2.4GHz bands. This new directive, EN 300 328 v1.8.1, requires Clear-Com to modify its HME DX-Series wireless intercom products and ship only v1.8.1 compliant products into countries that require CE compliance, beginning January 1, 2015.

What is EN 300 328 v1.8.1?

A new ETSI standard to address inteference issues within the 2.4GHz ISM band.

The main changes relate to how devices communicate and allocate radio space when they are in the same area. A new "adaptive mode" is required, which provides a mechanism so equipment can adapt to its environment by identifying other transmissions present in the 2.4GHz band.

How will this affect Clear-Com HME DX-Series products?
Clear-Com has modified its HME DX-Series wireless intercom products to be v1.8.1 compliant and created new model numbers for products sold in EU countries.

Characteristics of new v1.8.1 compliant product:
  • Spectrum-friendly feature will no longer be available.
  • New beltpacks will be backwards compatible with older versions of the base stations.
  • Older versions of beltpacks will not work with new base stations.
  • Testing is more important when installing in order to determine antenna placement and coverage area, particularly when other 2.4GHz equipment is nearby.
