The AFS-16 offers three different methods for switching A/B
1. Manual A/B Switching: Manual A/B Switches are used to
initiate switching of one or more Circuit Modules.
2. Code Activated A/B Switching: ASCII commands are
sent to the Control Module to initiate switching of one or
more Circuit Modules.
3. Automated A/B Switching (Monitor Mode): The AFS-16
monitors a signal received via the Control Module AUX
Port, and switches one or more Circuit Modules according
to user-defined parameters.
These methods are discussed in the sections that follow.
5.1. Manual A/B Switching
The most basic method for switching A/B paths is accomplished
using the manual A/B toggle switches on the Control Module and
on each Circuit Module. When performing Manual A/B
switching, note the following:
·The Control Module's Master A/B Switch can be used to
switch all sixteen Circuit Modules.
·The Master A/B Switch can be enabled or disabled by
positioning a jumper on the Control Module board as
described in Section 3.3.2.
·Each individual Circuit Module can be set to ignore or obey
the Master A/B Switch by positioning a jumper on the
Circuit Module board as described in Section 3.4.
