defective due to workmanship or materials and has not been caused by mishandling, negligence on behalf of the User,

Disposal of the Product The product must never be dumped in the Municipal Waste. Please check your local regulations
for disposal of electronics products.
Made In Italy : We stress the fact that all the boards are made in Italy because in this globalized world, where getting
the lowest possible price for products sometimes translates into poor pay and working conditions for the people who
make them, at least you know that who made your board was reasonably paid and worked in a safe environment. (this
obviously applies only to the boards marked "Made in Italy", we cannot attest to the manufacturing process of "third
party" boards).

HV outputs are delivered through SHV connectors. “Mixed” versions have two positive and two negative
channels.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel with 1
V/s steps. The module features 16bit ISET/IMON resolution. Optionally, the modules can be ordered with
current monitor resolution extended by 10x in a Lower range (selectable via software).
Safety features include:
•OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed
value
•OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it is
turned off
•Channels can be enabled or disabled through the Interlock logic
•Channels individually enabled via front panel jumpers (passive or active mode available)
Functional parameters can be programmed and monitored via USB and Ethernet (external PC required),
supported OS: Windows 7 or later; Linux kernel Rel. 2.4 or later.

2. Technical specifications
Packaging
The DT55xxE unit is a Desktop module housed in a 154x50x164 mm3 alloy box. The kit includes:
•DT55xxE desktop power supply unit
•External AC/DC power supply with separate power cord
•USB cable
•10BASE-T Ethernet cable
Power requirements
The module is powered by the external AC/DC stabilized power supply included in the delivered kit
(Switchbox Model FRA045-S12-4; see specifications in table p.5)
Note.: Using a different power supply source, like battery or linear type, it is recommended the source to
provide +12V and, at least, 2.5A; the power jack is a 2.1mm type, a suitable cable is the RS 656-3816 type
(or similar).

Alarm signal
As an Alarm condition is detected (see p.) pins 2 and 3 (- and +) are closed; the contact can be used to
switch an external device supplied by an external source, otherwise the VB and GND references can be
used to provide a TTL compatible level on pin 2 and 3.
In the first case (externally supplied device) the maximum allowed ratings are:
•Maximum voltage between + and -: 12V
•Maximum sink current across + and -: 100mA
In the latter case, to produce a TTL compatible Alarm Out, pin 3 (+) must be connected with pin 4 (VB) and
pin 1 (GND) with pin 2 (-); see the diagram below:

Interlock signal
With reference to diagram of the Interlock input shown above, the diode is part of opto-coupler stage.
Interlock means that channels are hardware disabled. The interlock operation is as follows:

The front panel Interlock LED is ON when the INTERLOCK is active; as INTERLOCK is active, channels are
turned off at the fastest available rate, regardless the RAMP DOWN setting.

CAEN HV Wrapper
CAEN HV Wrapper is a library, available either as a set of ANSI C functions or LabVIEW™ VI’s. Such set
provides the software developer an unified software interface for the control of CAEN Power Supplies.
This is a low level application in which the writing of the Control SW is assigned to the user. It contains a
generic software interface independent by the Power Supply models and by the communication path used
to exchange data with them.
CAEN HV Wrapper is logically located between an higher level application, such as GECO2020, and the
lower layer software libraries. For more info please visit www.caen.it (products>firmware/software
section).
Power Supply Modules LabVIEW Instrument Driver
Power Supply Modules LabVIEW Instrument Driver is a set of VI’S, developed for LabVIEW 2009 and later
releases (LabVIEW™ is a Trademark of National Instruments Corp.), that allow to configure and monitor
all parameters of remotely controlled CAEN Programmable HV Power Supply modules. Host PC shall run
LabVIEW 2009 or later releases and NI-VISA Run-Time Engine 5.3.
To install the Power Supply Modules LabVIEW Instrument Driver, go to CAEN web site in the “Software”
area, download the Power Supply Modules LabVIEW Instrument Driver installation package and follow
the Set Up instructions.

4. VT emulator control
Module access
The module is provided with a USB2.0 compliant interface and Ethernet Port (TCP/IP).
For link connection, refer to instructions given at page 10.
CAEN provides the CAEN GECO2020 Control Software that allows a friendly remote management of all
Unit’s functional parameters (see www.caen.it software support page); anyway, the connection can be
performed also via VT emulators, we suggest to use Tera Term (see https://ttssh2.osdn.jp/index.html.en)
USB
Launch the terminal emulator (we suggest using
Tera Term), select the serial communication link
and set the virtual communication port
associated to the module. Select USB connection
and the used port number; set port as follows
baud rate 9600
Data bits: 8
Parity: none
stop bit: 1
Flow control: none
Launch communication
Type caen then <enter>;
Ethernet
Launch the terminal emulator (we suggest using
Tera Term), select port number 23
Please note that line editing must be disabled prior
to Ethernet access.
Default settings are:
IP address 192.168.0.1
Subnet mask 255.255.255.0
Gateway 255.255.255.0
Launch communication
Type caen then <enter>;
as the communication is established, the Main Menu will be displayed:
Fig. 10: Terminal Board Menu
Five options are available:
•Display
•Format
•Update
•Ethernet
•Quit
Ethernet configuration
To configure the Ethernet Port; with reference to Fig. 10: Terminal Board Menu, Type E; the following
screen will open:

CAEN
Electronic Instrumentation
DT55xxE Desktop HV Power Supply

Fig. 11: Terminal Ethernet settings
At first Power On the module is configured with default static IP (factory setting); such IP can be updated
using the “arrows” to select the fields, typing the new values and confirming with <Enter>.
Type S to save the new setting in the EEPROM and go back to Main Menu.
The new setting will become active at next Power On; if a DHCP Server is available, then the module can
be enabled or disabled as DHCP client; type S to save the new setting in the EEPROM and go back to Main
Menu: the DHCP server will automatically assign a new IP to the module at next Power On.
Firmware upgrade

•unplug the USB cable
•do not turn off the module!
•connect once again to the module, via USB
•the following message will be shown:
•Press any key
•Wait until the following message is shown:
