Model 5600ACO2 Automatic Changeover Unit
When individual Voting Control is enabled (through the serial port or Vistalink), the setting of DIP switch
4 is ignored, and the individual voting enables for balanced and unbalanced DARS will apply will apply.
See section 4.3.3 and 5.1.3.
3.3.5. AES Valid Condition
The AES valid condition is controlled by DIP switch 5.
DIP 5 AES Valid Condition
Off (Up) AES balanced or unbalanced
On (Down) AES balanced and unbalanced
Table 3-8: AES Valid Condition Switch Settings
When DIP switch 5 is in the Off position, the AES signal will be considered valid when there is a valid
signal into either the AES balanced input or the AES unbalanced input or both.
When DIP switch 5 is in the On position, the AES signal will be considered valid when there is a valid
signal into both the AES balanced input and the AES unbalanced input.
The signal presence will still be shown on the front panel LEDs regardless of this switch position.
When individual Voting Control is enabled (through the serial port or Vistalink), the setting of DIP switch
5 is ignored, and the individual voting enables for balanced and unbalanced AES will apply. See
section 4.3.3 and 5.1.3.
3.3.6. GPI Monitoring
The GPI monitoring function is controlled by DIP switch 6.
DIP 6 GPI Monitoring
Off (Up) GPI’s pass through but not monitored
On (Down) GPI’s pass through and monitored
Table 3-9: GPI Monitoring Switch Settings
When DIP switch 6 is in the Off position, the GPI’s on the AUX input DB9 connectors (from the
5600MSC) are passed through, but ignored otherwise.
When DIP switch 6 is in the On position, the GPI’s on the AUX input DB9 connectors (from the
5600MSC) are passed through, and added to the decision making process when in automatic mode. A
floating or high input is considered valid, and a low or shorted to ground signal is considered a fail
state.
This functionality is provided to use with the 5600MSC. By enabling the GPI monitoring mode, and
configuring the 5600MSC GPO outputs as failure tallies, the 5600ACO2 can be instructed to change
over on various failure modes in the 5600MSC. (i.e. power supply failure, or fan failure, or unlocked
etc.) See the 5600MSC manual for information on configuring the 5600MSC GPO’s.
