1. About this manual
The purpose of this guide is to illustrate:
•the several parameters and commands available for the control and status
monitoring of the SY2527 Universal Multichannel Power Supply System and of
the board channels,
•the requirements and instructions for its correct operation in different hardware
configurations,
•the User Software Interface used to control the system interactively.
The preliminary section of the guide starts with a short description of the SY2527 system
with a summary of its main features and performances.
The core of the guide consists of two sections:
a reference section with a detailed description of the commands, alarms and parameters
which allow for the control and monitoring of the system and of the board channels;
a second section which illustrates the operating modes of the SY2527 system for
different hardware configurations for interactive control of the system, paying particular
attention to the User Software Interface for standalone and terminal operation.
A detailed description of all hardware components and system installation instructions
can be found in the Hardware Installation Guide.

The conventions adopted all through the manual are shortly listed in the following.
1.2.1 Safety rules
The user is requested to pay particular attention to the parts of the document containing
the following terms:
WARNING:
Warning statements identify conditions or practices that could result in injury or
loss of life.
CAUTION:
Caution statements identify conditions or practices that could result in damage to
this product or other property.
Please pay particular attention to the grey areas where warning and caution statements
are emphasised, as shown in the following examples:
CAUTION
PLEASE NOTE THAT THE FAN TRAY GRID MUST
NOT BE COVERED UNDER ANY CIRCUMSTANCES!
WARNING
DO NOT OPERATE WITHOUT COVERS!
1.2.2 Electrical signal specifications
The polarity of the electrical signals can be chosen via software by the user. As a
consequence, in this guide it has been adopted the following convention:
TRUE: an electrical signal is indicated as TRUE when it is active.
FALSE: an electrical signal is indicated as FALSE when it is not active.

2. General description of the system
This preliminary section contains a short description of the SY2527 system with a
summary of its features and some tables with its main technical specifications.
A detailed description of technical specifications and hardware installation instructions
can be found in the Hardware Installation Guide.
2.1 Overview
The SY2527 system is the small scale experiment version of the latest CAEN
UNIVERSAL MULTICHANNEL POWER SUPPLY SYSTEM. This system outlines a
completely new approach to power generation and distribution by allowing to house, in
the same mainframe, a wide range of boards with different functions, such as High/Low
Voltage boards, generic I/O boards (temperature, pressure monitors, etc.) and branch
controllers, where the latter are used to control other remote generators and distributors.
Modularity, flexibility and reliability are the key-points of its design, enabling it to meet
the requirements of a wide range of experimental conditions. The latter range from those
of LHC experiments, in which the system’s features find prior application, to those of
other less challenging, but still demanding, High Energy Physics experiments.
The SY2527 mainframe is housed in a 19"-wide, 4U-high euro-mechanics rack and hosts
three main sections (refer to Fig. 2.1):
•the Boards Section, with 6 slots to house boards, distributors and branch controllers;
•the Power Supply Section
•the CPU and Front Panel Section which includes all interface facilities.
