IPA3000C01
The GPIO interface includes the following signals:
TERMINAL
NAME
FUNCTION
6
F_ASI_M
This input indicates that that an error has occurred in the signal received at the
main DVB-ASI input (ASI Main) somewhere before entering the Module.
5
F_ASI_R
This input is identical to the previous one except that is refers to the reserve
DVB-ASI input (ASI Res.).
4
F_IP_M
This input is identical to the previous one except that is refers to the main DVB
over IP (IP Main) input.
3
F_IP_R
This input is identical to the previous one except that is refers to the reserve
DVB over IP (IP Res.) input.
2
F_OUT
This output indicates that no signal is present at the output of the Module.
1
GND
Ground connection.
The rear interconnection board is not designed to withstand mechanical stress. The
wiring must be fastened properly to the frame where the mounting frame is housed to
prevent the rear board from supporting the weight of the cables.
3.6.1. Electrical DVB-ASI video connections
All DVB-ASI digital video electrical connections are BNC type. Below are several
recommendations to consider when wiring electrical signals.
BNC connectors used on cables must be suitable for the high frequencies of DVB-ASI
digital video signals: it is strongly recommended to use high quality connectors from
well known manufacturers.
All coaxial cable used must be Belden 8281 or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the IPA3000C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
The use of analog video coaxial cables (RG-59 type or similar) is not recommended for
digital video except for very short distances.
