MSD-244
RS422 signal splitter module with replaceable input card.
The MSD-244 is a 16 outputs 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: RS422(Rx), TTL@50Ω and GNSS receiver for 1PPS only. These modules split the following signals: 1PPS, ToD (NMEA), IRIG-B DCLS.
