Table 1: DIP SWITCH FUNCTIONS
For the ASI-CHO-2x1-PB, only DIPs number 2, 4, 5, and 8 (and 15+16) will have
any effect. The rest will be ignored and can be set to any position.
3.2 Gyda mode
All functions of the card can be controlled by the Multicon Gyda control system. In Multicon
Gyda the module has an information page and a configuration page.
3.2.1 Information page
The information page for ASI-CHO-2x1-PB is a subset of the information page for FRS-HD-
CHO, which in turn is a subset of the information page for FRS-HD-CHO-ASI. While the
FRS-HD-CHO and FRS-HD-CHO-
ASI only differ in that the latter has an extra line for “Input
signal type”, the ASI-CHO-2x1-PB information page is quite reduced, because the frame
synchronizer and audio embedder/d-
embedder functionality quite simply isn‟t included. The
difference between Figure 3 and Figure 4 should make this clear. The following paragraphs
will describe the information page for FRS-HD-CHO(-ASI), but as far the mentioned items
are also present in the ASI-CHO-2x1-PB information page, the description will apply for that
product version as well.
The information page shows a dynamic block-diagram of the board and some additional
information in textual form. The block diagram updates with the boards status, showing input
signal selected, signals missing (by red crosses over signal lines), and routing through
switches. It also shows the audio matrix selections that have been made on the configuration
page.
Note that if embedded audio is missing from a group, the user will still be allowed
to select those inputs in the matrix, but the output will go to a fallback position.
Missing audio channels will be shown in the block diagram with a red cross over
the matrix input line.
The text on the information page gives information about functionality not displayed on the
dynamic block diagram.
The video delay represents the actual delay between input and output video.
If the ASI option has been purchased, th
e name of the module will have „-ASI‟ appended. In
addition, a line „Input signal type‟ followed by „SDI‟ or „ASI‟ will appear as a reminder of the
selected mode, ASI or SDI.
