11 Additional Information
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 inadequate 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 will show 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 mqm6000L may 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 willnot
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.
