Description
A
INTFC 7: GEN
Interface 7 Generator Port Identification label. This option is an information-only
label identifying the menu.
B
03
EA_PORT Generator Port function parameter. This option displays the logical port
from which the
EA-PID is blocked during an emergency alert condition. 03 is the default value.
0-16 is the valid range of values for this field.
C
UP
Up option. This option returns to the MAIN menu.
D
1503H
FFFFH
FFFFH
FFFFH
EA-PIDS map option. This option displays the EA-PIDs that are blocked during an
emergency alert condition. Up to four EA-PIDs can be blocked. 1503H is the
default value. 0000H to 1FFFH is the valid MPEG PID range for these fields. A
value of FFFFH (invalid) in any of the four fields indicates that no EA-PID is
blocked for that field. These fields are edited in the
OM1000.ini
file.
Emergency Alert (EA) functionality is not required outside the United States.
Setting Up PID Maps
You must set the routing for the PID map default entry and set the PID re-assignment and
packet routing for each individual PID to be remapped or reassigned.
CAUTION
When setting up the PID maps for the GEN port, ensure that the input PID values are different. For the internal
generator, the buffer used to store PID values is static and is used repetitively. If a mapped value enters the GEN port
that matches an existing PID value, the value is overwritten, which forces the default entry to take effect and nullifies
the mapped value.
Refer to Setting PID Maps to set up PID mapping for the internal generator port.
