Baldwin Boxall Digital-to-analogue Converter BDM400IF

The BDM400IF is an Interface Module for the BDM400 range of RS485 serial microphones. The module interprets the RS485 serial data produced by the microphone and converts this information into conventional parallel terminations. This enables the BDM400 range of microphones to be retro-fitted to existing installations and also allows them to be used in new installations that do not have an RS485 system controller.

The BDM400IF allows a BDM400 microphone to be retro-fitted to an existing system through a BMS25 termination unit using a 25way D type cable. In addition to providing a direct connection to an existing system the BDM400IF also provides extra terminations to access the enhanced features of the BDM400 range of microphones if required.
