EH244 ENCODER HOST SERIES

CONFIGURATION (continued)

DHCP: ENABLED, DISABLED – this configures the ethernet control interface to use DHCP for its IP configuration settings

when enabled, or to use the static IP configuration that follows when disabled.

IP ADDRESS: Variable – this sets the ethernet control interface's static IP address when DHCP is disabled.

SUBNET MASK: Variable – this sets the ethernet control interface's IP subnet netmask when DHCP is disabled.

GATEWAY ADDRESS: Variable – this sets the default gateway for the ethernet control interface when DHCP is disabled.

DTA/EAS CONTROL: DISABLED, MASTER, SLAVE – this sets the unit's EAS and DTA control mode. When MASTER,

the unit is the first in the daisy chain of Drake devices; when SLAVE, the unit is not the first in the daisy chain.

DTA MODE: DISABLED, ENABLED – this enables the DTA control feature of the unit (which allows SCTE65 control

messages to be passed out to low-cost DTA settop boxes for channel lineup and firmware update purposes).

EAS MODE: DISABLED, MODULE 6, SCTE 18, MODULE 6+SCTE 18 – this sets the EAS mode in use. MODULE 6

replaces all video and audio streams with the input from the EAS encoder when an EAS alert is active. SCTE 18 sends

the SCTE 18 EAS control messages when an EAS alert is active. MODULE 6+SCTE 18 performs both actions when an

EAS alert is active.

EAS RF CHANNEL: Channel number – this configures the SCTE 18 force-tuning RF channel number that every receiver

should tune to during an EAS alert.

EAS MODULATION: QAM-64B, QAM-256B – this configures the SCTE 18 force-tuning channel modulation method that

every receiver should tune to during an EAS alert.

EAS MPEG PROG #: Program number – this configures the SCTE 18 force-tuning MPEG program number that every

receiver should tune to during an EAS alert.

EAS MAJOR CHAN: Major number – this sets the PSIP major channel number of the SCTE 18 force-tuning channel.

EAS MINOR CHAN: Minor number – this sets the PSIP minor channel number of the SCTE 18 force-tuning channel.

PACKET DELAY: 0-200 usec – this sets the delay interval between encoder output packets, in microseconds. This

setting may be used to enable older settop boxes with small decoder buffers to work with the SDE24 encoder's output

stream. If needed, a setting around 70-100usec works well, but this setting must be tweaked for each encoder based on

the deployed settop boxes.

OUTPUTx BITRATE: Variable – when a specific output is not being used for generating a QAM channel, the output

bitrate may be varied to allow for more flexible deployments. This allows the optional ASI outputs to run at higher than the

standard QAM data rates (or lower, if they will be used in conjunction with an external lowerbitrate modulator).

ENCODER x: OUTPUT - x – this setting allows each encoder's output program to be assigned to any or all of the output

channels, by cycling through all of the options.

MGT/VCT: DISABLED, CVCT, TVCT – this sets the MGT/VCT table style to the cable (CVCT) or broadcast (TVCT)

standard as needed by the deployment.

VIRTUAL+MPEG #s: DEFAULT, USER DEFINED – this setting allows the operator to override the default virtual channel

numbers (which default to RF_channel_number - encoder_index_number). The user-defined settings must be set from the

ethernet control interface.
