NMEA Buffer MR-208

Product Description

The MR-208 device can be used in buffer or splitter configuration. Two (2) listener inputs and eight (8) talker outputs are provided for this purpose., The on-board switches (DIP Switches) DIP 1 and 2 are used to provide configuration options., Switches 3 and 4 are used to provide the Baud rate, so the device can parse NMEA and AIS messages., When setting a standard Baud rate, the device sets both Listeners L1 and L2. When using the Auto mode, the device will check L1 and L2 independently., The MR-208 device incorporates LED indicators for status updates.
