CHAPTER 4
INSTALLATION AND SETUP
INTRODUCTION
The MT930B is designed for installation in a standard 19-inch equipment rack.
Individual units are rapidly installed and are easy to configure requiring simple
tools but no soldering (unless needed for your cables) or external test
equipment.
SET INTERNAL SWITCHES FIRST
Before installing a unit in a standard 19-inch equipment rack, make sure all
internal switches are set to the positions desired. Chapter 3 illustrates the
internal switches that control video inversion and their locations. We expect only
limited users may need these switches. All others will need factory default
position.
RACK MOUNTING
1. Install the first receiver (if more than one is to be installed) to the
position of choice. If a rack is to be full, start with the bottom position
and work upward, leaving one rack unit (1¾ in.) between each unit for
adequate cooling. The open space may be covered with a blank plate. If
other equipment is to be installed, make sure adequate cooling is
provided for all equipment within the rack.
a. Slide the unit into the rack opening.
b. While holding the unit level, secure the two front mounting brackets
with four user-supplied screws and/or washers.
2.
See the separate section at the end of the chapter regarding the RS-
232C and CONTROL I/O connectors and their use in remote control
operation.
CONNECTIONS
1. Connect L-band input(s), up to four, to RF INPUT ports #1, #2, #3,
and/or #4 as required. With user editing of the internal satellite
database, any port can be used for any input, but we recommend C-
band Vertical be connected to #1, C-band Horizontal to #2, Ku-band
Vertical be connected to #3, Ku-band Horizontal to #4 to maximize the
pre-programmed database which assumes these connections.
