ADDITIONAL INFORMATION

SET TOP BOX MAPPING

The output stream of the MQM6000L will contain programs

xx - 1 thru 6 where xx is the RF output channel and 1 thru 6

are the MPEG program numbers assigned that correspond

to the ASI inputs1 thru 6.

STANDBY MODE

The MQM6000L has a standby output mode which turns

off the RF output. This can be used when it is desirable to

temporarily disable the output without unplugging the AC

line cord. Select STANDBY in the OUTPUT FORMAT

menu.

OVER TEMPERATURE SENSOR

Temperature monitoring is built into this product. If inad-

equate ventilation is provided, overheating may occur. If

this condition is detected, the default LCD message will

change to OVER TEMP. If this occurs, the problem should

be corrected as soon as possible. The unit will remain

operational but the ventilation must be restored to prevent

premature part failures due to overheating.

STATUS DISPLAYS

When the units are not in the adjust/program mode, status

displays are shown. The default display shows the QAM

OUTPUT in Mbits/S. Pressing the down arrow button

willshow the percentage of buffer capacity that is currently

in use on the left side of the display and the maximum

percentage of buffer capacity that has occurred since the

unit was last programmed is displayed on the right side.

Pressing the up arrow button will show the firmware version

number.

REMOTE CONTROL AND MONITORING

The MQM6000Lmay be used with the 'Drake Digital

Headend Remote Control Software' program to allow

remote monitoring or control. Make sure that the version of

the program includes the MQM6000L. Earlier versions will

not operate with this unit.

Connect the RS232 cable coming from the PC or modem to

the RS232 IN DB9 rear panel connector.

Assign a UNIT ID (1 to 63) to use the remote program.

Leave at, or set to, 0 if no remote access is desired.

Set the RS232 BAUD RATE to match the PC setting.

If you are familiar with the program, operation will be clear.

If not familiar with it, see further instructions in the insert

provided with the CDROM or stored on the CDROM.
