The EMA Adaptor Board 9612 for Iridium SBD modems allows hassle-free replacement of existing SBD 9601 with next-generation modem SBD 9602.
The Iridium 9602 SBD is smaller and cheaper, but it connects and communicates differently, so a redesign of the device that integrates the old transceiver was necessary in order to install the new one. With the EMA Adaptor Board 9612 redesign can be avoided and 9602 transceiver fitted in the 9601’s place with no extra development effort.
