7.5.1.6 IDENT XBAR Interface
If a Venus preselection matrix or a Jupiter c ontrol system is connected to the
production switchers, the IDENT XBAR protocol may be used to transmit
the abbreviated names of the sources corresponding to the current switcher status
from the matrix to the switcher. The current source name is then indicated in the
displays (option) of the source selection keys.
Installation The installation of this mode of operation is made in the INSTALL EBOX menu (see
above). The IDENT XBAR protocol must be selected for the port that is linked e.g. to
the router’s controller interface.
Note: The controller interface must have the corresponding software. For
the Jupiter control system a VM board or a SI board is available as
interface.
The protocol serves to transmit mnemonic codes to the switcher at a rate of
38.4 kBaud, 8 databits, no parity, 1 stop bit.
The transmission can be made from any computer system with a serial interface.
The serial interface must correspond to the RS-422 standard.
In this mode the switcher operates as tributary, the port (9 pin D-sub, female) of the
switcher is assigned as follows:
Pin 1, 9 Frame ground
Pin 2 Transmit A
Pin 3 Receive B
Pin 4 Receive common
Pin 5 not connected
Pin 6 Transmit common
Pin 7 Transmit B
Pin 8 Receive A
