Description
VBI MODE Off,
16_LINES_PT,
32_LINES_PT,
TIERNAN_CC Off Configures the encoder to transmit either 16 or 32
lines of VBI information or Tiernan proprietary
closed caption mode
? Off – disables expanded windows mode.
? 16_lines – enables 16-line expanded
windows mode.
? 32_line – enables 16-line expanded windows
mode.

TIERNAN_CC – Line 21 encoded
Tiernan mode
VBI VBI_QUANT 1 - 31 1 Sets the Quantization (number of pixels per data
bit) for VBI. Setting higher quantization levels will
provide lower bandwidth utilization at the expense
of decreased VBI data resolution.
NOTE: This parameter is for advanced users
only.
VBI VBI_END 6 - 23 21 Sets the last VBI encoded line.
NOTE: This parameter is for advanced users
only.

The SE4000 contains a bank of flash memory that is used to store firmware, software, and hardware
configuration files as well as unit configuration parameters. Parameter changes made using the front
panel are automatically stored in flash memory. When the SE4000 is reset, any changes made using
the front panel are restored. Any parameter changes made using a remote unit are not automatically
stored in flash memory. If the SE4000 is reset prior to issuing the CM SAVE command, any changes
made using the remote unit will not be restored. Instead, the SE4000 restores the last changes saved
to flash memory. When the SE4000 configuration is changed using a remote unit, an operational test
should be performed to verify that the system is operating correctly. Then the new configuration
should be saved by issuing the CM SAVE command. Once the configuration is saved, the SE4000
automatically restores saved settings when the unit is reset or powered up.

Command only valid when MUX CM is set to Redund.

Refer to the MUX RED_STATE command for additional information.
Tiernan standard product NMS backward compatability
For compatibility with NMS designs based around the Tiernan TE6000 modular products, the
SE4000 will accept slot numbers in mnemonics. For example:
AE A BR 256000 sets the Audio A bit rate to 256000. The SE4000 will accept AE.1.A BR 256000
as an alternative. The slot number is accepted but ignored.
