B.5 USING METACAST 2 WITH THE 8084AD
MetaCast 2 is a Windows software application that schedules the XDS packets sent by the 8084AD
Encoders according to the program schedule currently being aired. It allows the station operator to
program XDS packets such as show name, duration, V-chip rating for each program segment. In order
to accomplish this in sync with the programs being aired, MetaCast 2 needs to have a stable time
reference. The preferred method is to have MetaCast 2 read the time from the 8084AD (which is in
turn reading the time from the house time code reference). MetaCast 2 will maintain this time internally
as the Broadcast Time and use it to control the scheduling of packets.
MetaCast 2 also provides tools to monitor and set the time, date and time zone offset of the encoder, to
manage changes to and from Daylight Saving Time and to enable and disable the transmission of XDS
Time of Day and Time Zone packets. These tools are available by opening the Clocks windows from
MetaCast 2's tool bar.
B.5.1 Connecting MetaCast 2 to your 8084AD
You can connect one of the serial ports on your PC to any port on an 8084AD using an ordinary NULL
modem cable that should have been supplied with the 8084AD encoder. The next step is to ensure
that both devices are using the same communication settings. For the 8084AD Encoder, these can be
selected from the front panel engineering menu. Check your encoder manual on how to change the
port settings. It is recommended that the 8084AD be set at 9600 baud, 8 data bits and no parity.
The next step is to configure MetaCast 2 to the same settings. The encoder communication settings
can be found under Comm Settings in the Encoder menu. On the dialog form, select the PC port to
which the 8084AD is connected and choose the same settings in the designated combo boxes. For
