The common port ("Out") can be switched to one of two input/output ports ("In A",
"In B"). The unused input/output port is terminated internally. Latching relays are
used for switching.

DEV 11-0010
Two input ports ("In A", "In B") can be switched to one output port ("Out"). The
unused input port is terminated internally. The module is able to pass an external
10 MHz reference signal.
The module provides RF level monitoring, i.e. the RF level of both input ports is
measured and is compared with (adjustable) RF threshold levels. This enables the
functionality to indicate an event (if the present input signal levels are below a
threshold level), and/or permits the DEV 1951 to control the switching
autonomously.

DEV 11-0011
The functionality of the module DEV 11-0011 is identical with the module
DEV 11-0010 (please refer to chapter 3.2.3), but the module is designed for a
different frequency range.
