4.14.2 Special func tions featured by Macro protocol
4.14.2.1 Polling

Communication between keyboard and matrix is based on polling techniques.
If the keyboard is connected to a personal computer or another OEM device the polling can be suspended to
ease the implementation of a Macro protocol and avoid the need to respect very strict timing requests.

Set to YES if the multiplexer Sanyo is connected to a matrix Aux line. When enabled a set of special screens
are available on the keyboard.
If the multiplexer is directly connected to the keyboard set to NO.
4.14.2.3 9999 Camer as
Default: NO.
Set to YES if the system is composed by a group of matrixes (instead of a single one) and allows to control up
to 9999 cameras.
4.14.2.4 Decode Rec eivers
Default: YES.
Usually to a video input corresponds a telemetry receiver/dome identified by the same number (video input
1/receiver 1, video input 2/receiver 2, etc.)
When this easy association is not possible either the keyboards or the matrix has to manage the link between
identification numbers. Not every matrix model can manage this feature.
When decoding is performed by the matrix it is not possible to choose receiver numbers from the keyboard. The
respective receiver number is not read on display.
