ACO-4500 User Guide (v3.0) Front Panel Menu System • 39
The number of channels displayed in this menu will be the same as that previously set in the menu item: Main
Menu | System | Number of Channels. If there are more than 5 active channels, these are accessed by scrolling the
menu downwards.
The menu displays the signal type to which each BNC channel is set to monitor. Each setting is selected from the
list of supported signal types.
All input signals are detected for amplitude. Some signal types have pre-defined fault levels associated with them,
and are used to determine whether an error has occurred. Other signal types have a simpler “Loss Of Signal”
detection system. For the special case where signals are present but not required to be monitored for the purpose of
errors, the “No Measurement” setting should be used.
Installation Scenarios
The most common scenario is one where a specific number of signals are required to be both monitored and
switched. In this case, the “Number of Channels” setting will correspond with the same number of “Channel
Configuration Menu” lines, all set to their relevant signal types.
Another scenario is one where more signals are required to be switched than monitored. On the ACO-4500, when a
fault occurs, ALL channels switch, regardless of how many inputs are populated or configured. So, for this case, the
user can either:
• select the 'additional' channel types as “No Measurement”, or,
• reduce the “Number of Channels” setting to correspond to the actual number of inputs to monitor, rather than the
number of inputs connected.
Channel # Type
The options displayed in the field “#” are: 01 up to the “Number of Channels” setting.
Upon entering this menu, rotating the rotary control allows the user to select a channel to adjust. Pressing the rotary
control allows the user to adjust the selected channel.
The options for the type are:
• No Measurement
• Color Black (no ancillary signals present, i.e. only Sync & Burst)
• Color Black + VITC (with one or some ancillary signals present)
• 600mV TriSync
• SD SDI - LOS
• HD SDI- LOS
• 3G SDI- LOS
• 1V 10MHz
• 1V Subcarrier
• 1V AES
• 2V Pulses- LOS
• 4V Pulses- LOS
After making your selection, press the rotary control to confirm the selection. Select additional channels to adjust.
When finished, press the push-button to return to the Main Menu.
