REMOTE CONTROL AND MONITORING
The MQM6000Lmay be used with the 'Drake Digital

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.

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.

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
