Safety Instructions
å Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the
maximum ambient temperature per Section 2.3.
å Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment
is not compromised.
å Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
å Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of
the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
å Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g. use of power strips).
å Read all safety and operating instructions before you operate the unit.
å Retain all safety and operating instructions for future reference.
å Heed all warnings on the unit and in the safety and operating instructions.

QTPCM-4 (QAM Transcoder Power Control Module) provides control and monitoring of QTM-HD-4 (6243), QTM-HD-4-NPU
(6223) and QTM-HD-Plus (6242) transcoder modules via GUI-based web pages. Local or remote control via the Internet is
accomplished with any computer running a standard web browser. The QTPCM-4 will power up to four (4) QTM-HD-4 (2
slot width) or four (4) QTM-HD-4-NPU (2 slot width); eight (8) QTM-HD-Plus (1 slot width); or a combination of modules
all housed in a QTRC (stk# 6233A) rack chassis. The 3RU chassis, when fully loaded with four (4) QTM-HD-4 or (4) QTM-
HD-4-NPU and a QTPCM-4, will transcode sixteen (16) QPSK/8PSK satellite transponders to sixteen (16) QAM channels.
The QTM-HD-4 contains (4) independent transcoders in a single module. Each transcoder accepts one (1) input in QPSK or
8PSK format and delivers (1) QAM channel output, therefore each QTM-HD-4 module transcodes (4) satellite transponders
to (4) QAM channels (54-864 MHz). An integrated satellite selector switch allows the operator to select any of the 4 inputs
to any of the transcoders without the need for an external multi-switch.
The QTM-HD-4-NPU functions the same as the QTM-HD-4, but with a “Null Packet” feature that allows adding/removing
null packets to/from the input stream.
The QTM-HD-Plus features a single transcoder, accepting a QPSK or 8PSK input and delivering a single QAM channel output
in the frequency range of 54-864 MHz. This module is typically used in applications requiring QAM 512/1024 modulation.

It is recommended to disconnect AC power to the QTPCM-4 when installing or removing QTM modules. When replacing
QTM Modules, simply disconnect the input and output cables along with the power supply/control cabling and remove
the module from the chassis. Install a new “like”module and reconnect the cabling. The QTPCM-4 will automatically
configure the new module with the same settings as the replaced module.
If the QTPCM-4 has to be replaced, remove power and all cabling on the rear of the unit. Replace the module and
reconnect power and cabling. Once the new QTPCM-4 has booted up it will read the configuration settings from the
transcoder modules, store them in memory and return to full system operation, without any further user interface.

The "Time" screen (Figures 5.7a and 5.7b) allows the user to set the current date and time for the QTPCM-4. It is
recommended to use the "automatic" option which allows the unit to automatically acquire time settings from a "Time
Server", in which the user must enter the IP address of the time server (see Section 5.6.1 for details). The time server
specified must support the Network Time Protocol (NTP) in order for automatic time acquisition to work properly.
