DD2401 Satellite Demodulator Installation
MN-DD2401 - Rev. G 2-1
Installation 2
2.0 Installation Requirements
The DD2401 can be installed within any standard 19 inch equipment cabinet or rack, and requires
one rack unit (RU) mounting space (1.75 inches) vertically and 21 inches of depth. Including
cabling, a minimum of 23 inches of rack depth is required. The rear panel of the DD2401 is
designed to have power enter from the right and IF Cabling enter from the left when viewed from
the rear of the unit. Data and control cabling can enter from either side although they are closer
to the right. The unit can be placed on a table or suitable surface if required.
There are no user-serviceable parts or configuration settings located
inside the DD2401 chassis. There is a potential shock hazard internally
at the power supply module. DO NOT open the DD2401 chassis under
any circumstances.
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 DD2401 configuration settings are unknown,
where incorrect setting could disrupt existing communications traffic.
2.1 Unpacking
The DD2401 Modulator was carefully packaged to avoid damage and should arrive complete with
the following items for proper installation:
1. DD2401 Satellite Demodulator
2. Power Cord, six foot with applicable AC Connector
