DC M&C Unit 1.2.5
This board includes a DC/DC converter, regulators, and a EMI/EMC filter to make all kinds of DC
voltages required in the BUC. It also contains a Monitor and Control (M&C) function to monitor and
control the BUC, and communicate with a remote modem unit. The key parts for the M&C function
are a microprocessor and communication ICs for RS-232 and Ethernet.
CAUTIONS AND WARNINGS 1.3
Read all the following instructions prior to using the BUC.
Introduction 1.3.1
There is a potential safety risk unless appropriate precautions are taken while working with the BUC.
All the precaution and danger notes must be carefully read before beginning to use the BUC.
ESD Protection 1.3.2
The BUC contains elements sensitive to electrostatic discharges (ESD). It is important that the staff
is ground-connected while they are working with them.
Cleaning 1.3.3
Do not use liquid washing products or aerosols. Only use a damp cloth for cleaning.
Water 1.3.4
Do not expose the BUC to standing water. Failure to follow this precaution could result in electric
shock and injury to persons.
Installation of the BUC 1.3.5
The BUC described in this manual should not be installed in an unstable situation because it may
cause serious injuries to persons as well as a severe damage to the BUC.
Power Supply 1.3.6
An external power supply is necessary to convert the input AC to +48V DC, and for the internal
DC/DC converter within the BUC to generate appropriate DC voltages for IF, LO, Up-converter,
SSPA, and DC M&C units.
