MSD-248
8 x M8 2xRS422 signal splitter module with replaceable input card.
The MSD-248 is an 8xM8 output 16x RS422 (Tx) splitter module with a replaceable input card. It is compatible with OCP cards and can be used as a multi-output splitter with signal-type conversion. Available inputs are M8 RS422(Rx), 2xSMA TTL@50Ω (internal only), and a GNSS receiver for 1PPS and ToD (NMEA) signals. These modules can split the following signals: 1PPS, ToD (NMEA).
