The 5600ACO/ACO2 Automatic Changeovers are intended for use
with two 5600MSC Master Clock/Sync Generators. The 5600ACO/ACO2 system uses latching
relays to ensure maximum reliability and minimal disruption in the event of any
failure. The complete system provides the highest level of security for
television station video and time synchronization systems. The 5600ACO is a 1RU
device which is an ACO for a subset of the 5600MSC outputs. The 5600ACO2 is a
2RU ACO for all outputs of the 5600MSC. Two power supplies are included as a
standard feature, to alleviate any single point of failure concerns.
The front panel has three switches, recessed into the panel
for added security. There is an AUTO/MANUAL switch, a GPI/FRONT PANEL switch
and an A/B select switch for manual changeover. In automatic mode, all signals
from both 5600MSCs are monitored to detect any abnormal signals. For example,
if a level, pulse width, phase, time code error or other abnormality is
detected, the 5600ACO’s circuitry will trigger and the entire bank of signals
will be switched to the backup 5600MSC. In manual mode the changeover can be
operated from a GPI or from the front panel switch. LEDs provide status
information as to the health of the two 5600MSCs, together with indication as
to which one is active. In addition, two GPO outputs indicate which master is
active and when the inputs from both masters are not the same.
The 5600ACO2 features selectable voting via VistaLINK® for
autochangeover features. Individual inputs may selectively be included or
excluded in the voting process to drive autochangeover logic (feature only
available on 5600ACO2 model).
Each 5600MSC is equipped with 2 GPI inputs and 2 GPO
outputs. To facilitate installation, these connections are brought through to a
2x6 pin terminal block on the 5600ACO. The outputs from the 5600MSCs are passed
straight through the 5600ACOs. The inputs to the 5600MSCs are internally split
by a 'Y' connector, to ensure that both 5600MSCs receive the same GPI contact
closures.
In the event of a changeover occurrence, it is necessary
that all outputs on one 5600MSC have the same timing as those on the other.
Identical timing for both 5600MSCs is assured by locking both to the same
frequency and phase source (e.g. GPS or by genlocking one 5600MSC to the
other). Identical phasing of the independent black outputs is assured by
implementing the "Syncro" mode in the 5600MSCs. To use this mode,
both 5600MSC communication ports are connected together using the link cable
supplied with the 5600ACO. With both 5600MSCs operating in Syncro mode, timing
adjustments made to one 5600MSC will be automatically applied to both. The link
cable is connected permanently, so that any system re-timing will be applied to
both 5600MSC units (See system connection diagram on 5600MSC brochure).
Technical Details
• Three front panel switches select automatic, front panel
or GPI activation of changeover
• Front panel switches are recessed to prevent accidental
operation
• Front panel status LEDs show the health of each of the
inputs
• Front panel status LEDs show the operational modes of the
changeover
• Redundant power supply standard
• GPIO input/outputs
• Automatic changeover is a voting system based on which
source has the most valid signals and that the valid signals on the present
master are also on the backup
• VistaLINK® control for device configuration and status
monitoring (5600ACO2 only)
