1.1 Overview
The RRS11 Solid State Transfer Switch offers IF or L-Band redundancy for the DM240XR in a
simple straight forward plug and play design. The RRS11 includes monitor ports that allows the
user access to the online and offline ports. The RRS11 also includes front panel LEDs that
indicate online status of the modulator.
The RRS11 can be configured to support 70/140 MHz or L-Band System. An external power
source is not required. DC power and fault status is supplied to by each DM240XR. The RRS11
will trigger a switchover in the event that the modulator faults. Figure 1-1 through 1-4 illustrates
the front panel and rear panel of the RRS11 models.
