User’s Manual 3
This document describes the technical and functional characteristics and how to use the DIPOT board.
The available models are identified by the following codes:
1. E6102094300xx : DIPOT RS485 IN 0÷5V/IN 0÷10V
2. E6102094301xx : DIPOT RS485 IN TEMP./PRESS. VDO
3. E6102094302xx : DIPOT CANBUS IN 0÷5V/IN 0÷10V
4. E6102094303xx : DIPOT CANBUS IN TEMP./PRESS. VDO
Thanks to its versatility, the "DIPOT" device lets you connect most products (Speed regulators, Voltage
regulators, Power factor controllers, etc.) that require a voltage or current input, to suit their variation and
management specifications. The output for piloting the boards is managed by a microcontroller that
controls the regulation of an output proportional current loop (which can be converted into a voltage
output using a simple resistance).
The output can be regulated and piloted with UP and DOWN digital inputs, or by modifying the Modbus
protocol registry value via RS485 connection or CANBUS J1939 connection to our generator
management boards DST4601, DST4601PX, DST4400, etc.
2.1
On all DIPOT models, the regulation of the Current Loop can be selected using three configurations of
dip-switches:
from 0 to +20 mA
from -10mA to +10mA
from -20mA to +20 mA
Using one of the current adjustable outputs we can create a voltage output by connecting a resistor to
pins 2 and 3 of connector J1.
The current loop device output is between pins +4, +3 for the positive, and pins -2, -1 of J1 for the
negative. The resistor can be connected to pin 2and pin 3of J1 .
Warning: Carefully consider the resistor and the dip-switch configuration, as the max.
voltage range is ± 11V.
Here are some examples:

Voltage required: min. -6V to max. +6 V.

2.2
Connector J5 is used for the power input; input voltage can be either 12 or 24VDC, with a self-rearming
internal fuse. The device is protected by input polarity switching.
The maximum current absorption is approximately 80 mA at a voltage of 10V. The input voltage range
is between 7.5 and 32 VDC.
Configuration:
-J5 –PIN 1: positive input
-J5 –PIN2: negative input
-J3 –PIN6: Ground (cable screens)
Wiring Diagram:
The DIPOT board has several dip switches, which let you set the specific functions of the device, the
current loop value and the properties of the serial port.
The SWE switch is an 8-way dip switch for setting the following specific functions of the product:
DIP 1-4 (Communication address: assign the modbus address to the device (in the CANBUS
version, the communication address is fixed)

User’s Manual 5
DIP 5(analog on CANBUS): enables/disables transmission via Can bus of the water temperature
and oil pressure sensors connected to the analog inputs of the DIPOT module (connector J2). In
the Can Bus version of the receiving device, the Can is always enabled, regardless of the state of
this switch, if SWE dip 7 is ON (REMOTE CONTROLS).
DIP 6 (CCW/CW): lets you switch the current loop output in relation to data control (and then
switch from CW to CCW operating mode). In CW mode, the request with a CANBUS/Modbus
message or from the UP button, for an increment in the command, will result in a drop in the value
of the output current while in CCW mode, the request with a CANBUS/Modbus message or from
the DOWN button, for a decrease in the command, will result in an increase in output current.
DIP 7 (REMOTE/LOCAL CONTROL): in "Local" mode the up/down/reset buttons are acquired
and let you change the current loop output value. In "Remote" mode, the current-loop output value
is determined by the CANBUS or Modbus command. With version RS485 in "Remote" mode, the
value of the MIN, MAX, RESET and RAMP trimmer is set in the "Holding register.
DIP 8(Rpm1500/1800 from CANBUS/DIGITAL INPUT): determines if the nominal speed of the
motor (1500 or 1800 rpm) is automatically detected by the CANBUS or digital input J3-2. (If the
input is active, the nominal speed is 1800 rpm, if the input is inactive the nominal speed is 1500
rpm).
Switch SWD is a 4-way switch and sets the properties of the available serial port on stereo jack connector
J6 and connector J4:
DIP 1 (120R ON/OFF): lets you connect/disconnect the 120R termination resistor on serial port
RS485 of J6 (only if necessary and if the port is set as RS485).
DIP 2 (Enable/disable Serial port): enables/disables the serial port on stereo jack J6.
In the versions with isolated RS485 (E6102094300xx and E6102094301xx) serial port of connector J4
is shared with connector J6. Use SWD dip 2 to select which port should be used. The serial ports on J4
and J6 cannot operate simultaneously. If the serial port is used on connector J6, disconnect the female
connector on J4.
In versions with CANBUS (E6102094020xx and E6102094303xx) the serial port on connector J6 is
always available.
DIP 3 (RS232/RS485): configures the serial port on Stereo jack J6 as RS232 or RS485 (not
isolated).
DIP 4 (9600/19200 Bd): sets the baud rate used by the serial port on Jack (J6) and also that of
isolated RS485 serial port (J4) if the product is version RS485.
The SWB switch is a 2-way switch and sets the scale of the current loop used:
from 0 to +20 mA SWB-1 OFF SWB-2 OFF
from -10mA to +10mA SWB-1 ON SWB-2 ON
from -20mA to +20 mA SWB-1 ON SWB-2 OFF
The SWC switch is a 4-way switch that lets you enable the voltage insulator function (Setting ON on
switch no. 1).
