Model 5600ACO2 Automatic Changeover Unit
3.2.1. Automatic Changeover Mode
To operate the 5600ACO2 in Automatic mode, set the CHANGEOVER MODE switch to the Auto
position. The 5600ACO2 will ignore the position of the other two switches in the Automatic mode. The
Auto LED will come on. The ACTIVE OUTPUT LEDs will indicate the currently selected master. The
5600ACO2 will decide whether to select the A or B inputs based on which source has the most good
signals and that the valid signals present on the currently selected master are also valid on the backup
master.
3.2.2. Manual GPI Changeover Mode
To operate the 5600ACO2 in Manual GPI mode, set the CHANGEOVER MODE switch to the Manual
position and the MANUAL CONTROL MODE switch to the GPI position. The Manual and GPI LEDs
will come on. The 5600ACO2 will decide whether to select the A or B inputs based on the ACO GPI
inputs on the top row of the terminal strip on the rear panel. There are two GPI changeover modes
described in sections 3.3.1. The ACTIVE OUTPUT LEDs will indicate the currently selected master.
3.2.3. Manual Front Panel Changeover Mode
To operate the 5600ACO2 in Manual Front Panel mode, set the CHANGEOVER MODE switch to the
Manual position and the MANUAL CONTROL MODE switch to the Front Panel position. The Manual
and FRONT PANEL LEDs will come on. The 5600ACO2 will decide whether to select the A or B inputs
based on the position of the FRONT PANEL switch. When the FRONT PANEL switch is set to A
Master A will be selected and the A LED will come On. When the FRONT PANEL switch is set to B
Master B will be selected and the B LED will come On. The ACTIVE OUTPUT LEDs will also indicate
the currently selected master.
3.3. DIP SWITCHES
There is an 8 position DIP switch located on the main circuit card inside the 5600ACO2. This DIP
switch is accessible through a cut-out in the rear panel of the unit. Table 3-1 shows the assigned DIP
switch functions.
