Channel Configuration Menu
Figure 5.5 provides an example of the Channel Configuration menu.
Figure 5.5 Channel Configuration Menu Example
The Channel Configuration Menu allows the user to configure each BNC channel to monitor the
incoming signal according to the selected signal type.
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-4400A, 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)
