Overview
The Radyne RCS20 M:N Redundancy Switch provides backup switching/protection for up to
nine pairs of satellite modem channels (modulators/demodulators). The RCS20 is a companion
product to the Radyne DD240, DM240, DMD15, DMD20, DMD2401, and DMD50 units. The
RCS20 may be referred to in this manual as the RCS20, "the switch", or "the unit".
The RCS20 can be operated automatically, in which case an automatic backup of a failed online
modem occurs after a preprogrammed delay. The switch may also be operated manually,
allowing the operator to manually switch to a backup modem.
