DM240XR High-Speed Digital Modulator Installation

MN-DM240XR– Revision 13 2–2

CAUTION

Before initially applying power to the unit, it is a good idea to disconnect

the transmit output from the operating ground station equipment. This is

especially true if the current DM240XR configuration settings are

unknown, where incorrect settings could disrupt existing

communications traffic.

2.2 Unpacking

The DM240XR Modulator was carefully packaged to avoid damage and should arrive complete

with the following items for proper installation:

 DM240XR Unit.

 Compact Flash Card. Must be installed.

 Power Cord, 6-foot with applicable AC connector.

 Installation and Operation Manual.

2.3 Removal and Assembly

Carefully unpack the unit and ensure that all of the above items are in the carton. If the Prime AC

power available at the installation site requires a different power cord/AC connector, then

arrangements to receive the proper device will be necessary before proceeding with the

installation.

The DM240XR modulator is shipped fully assembled. It does not require removal of the covers

for any purpose in installation. The only replaceable assembly in the unit is the data interface and

is not intended to be accomplished in the field. Should the power cable AC connector be of the

wrong type for the installation, either the cable or the power connector end should be replaced.

The power supply itself is designed for universal application using from 100 to 240 VAC, 50 to

60 Hz, < 40 W.

2.4 Mounting Considerations

When mounted in an equipment rack, adequate ventilation must be provided. The ambient

temperature in the rack should be between 10° and 35° C, and held constant for best equipment

operation. The air available to the rack should be clean and relatively dry. The DM240XR units

may be stacked one on top of the other up to a maximum of 10 consecutive units before providing

a 1 RU space for airflow.

Do not mount the DM240XR in an unprotected outdoor location where there is direct contact

with rain, snow, wind or sun. The DM240XR is designed for indoor applications only.

The only tools required for rack mounting the DM240XR is a set of four rack mounting screws

and an appropriate screwdriver. Rack mount brackets are an integral part of the cast front bezel

of the unit and are not removable.
