1Introduction
The all-in-one Digital Amplifier DAD 143.x is a universal device for any weighing, filling or dosing operations
and for force measurements with strain gage sensors. The DAD143 is designed for DIN (TS35) rail mount.
To grant the quality and allow legal weighing, the DAD143.x is OIML R76 approved (pending).
The DAD 143.x supports a number of industrial Ethernet based protocols for industrial weighing, control and
- -
Ethernet
for direct control of valves or bars etc.
The device can be controlled either by the front keys, via service port RS232 or 2 Ethernet based ports. The 2
logic inputs and 3 logic outputs make complex control functions easy. The 3 logic outputs can be controlled
external, too.

1.2 Safety Instructions
CAUTION: READ this manual BEFORE operating or servicing this equipment. FOLLOW
these instructions carefully. SAVE this manual for future reference. DO NOT allow
untrained personnel to operate, clean, inspect, maintain, service, or tamper with this
equipment. ALWAYS DISCONNECT this equipment from the power source before
cleaning or performing maintenance.
CALL Flintec for parts, information, and service.
WARNING: Only permit qualified personnel to service this equipment. Exercise care when
making checks, tests and adjustments that must be made with power on. Failing to
observe these precautions can result in bodily harm.
WARNING: For continued protection against shock hazard connect to properly grounded
outlet only. Do not remove the ground prong.
WARNING: Disconnect all power to this unit before removing the fuse or servicing.
WARNING: Before connecting/disconnecting any internal electronic components or
interconnecting wiring between electronic equipment always remove power and wait at
least thirty (30) seconds before any connections or disconnections are made. Failure to
observe these precautions could result in damage to or destruction of the equipment or
bodily harm.
CAUTION: Observe precautions for handling electrostatic sensitive devices.

Colour code of e.g. standard load cells
3.3 Load Cell Connection
The load cell wiring should be made carefully before energizing to avoid damages to the amplifier and the
load cells. The input resistance of the load cells that you want to connect should be 50 Ω(ohms).
In case of using a load cell / scale with 4 wire cable, you have to short-circuit (bridge) the pins 1 & 2 and 6 & 7.
Remark: -wire cable of a load cell, as the cable is part of the factory calibration
(signal & temperature compensation).

Traceable Access Code (TAC) protected calibration commands
In case the seal switch (pins 26) is open, the following commands or menus be proceeded:
- Calibration Zero
- Calibration Gain
- Calibration Absolute Zero
- Calibration Absolute Gain
- Calibration Minimum
- Calibration Maximum
- Zero Tracking
- Zero Range
- Display Step Size
- Decimal Point
- Calibration Save
- Factory Default
- Non Volatile Tare
- Non Volatile Zero
- Initial Zero @ power ON, etc.
Activity Link of Port 1/2
Setup or changes of calibration can only be performed with an
open seal switch (26). Changes lead to get a new TAC value,
increased by +1.
Running a legal for trade application needs the jumper
connected to the switch pins and a seal. A broken seal shows
up changes of calibration, which are not allowed.
Protected commands see below.

3.9 Logic Inputs & Outputs
The 2 inputs can e.g. get the function to act as the ZERO or TARE button, see chapter 8.10.
The 3 outputs act as switches for setpoints with hysteresis, switch behavior etc. Several reference values such
as net weight, peak weight or average can be used, see chapter 8.11.
3.10 Analog Outputs
The DAD143.1 offers 2 isolated analog outputs for current
and voltage. For your application you can choose one of the
six modes like:
➢4 to 20mA / 0 to 20mA
➢0 to +5V / 0 to +10V
➢-5 to +5V / -10 to +10V.
Note : The DAD143.2 has no analog outputs.

4Communications and Getting started
4.1 Service Port
Communicating with the digital device DAD 143.x is carried out via serial service port RS 232.
The data format is the familiar 8/N/1 structure (8 data bits, no parity, 1 stop bit).
Available baud rates of RS 232 port are as follows: 9600, 19200, 38400, 57600, 115200, 230400 and
460800 baud.
Factory default: 115200 baud
4.2 Command Language
The command set of the DAD 143.x is based on a simple ASCII format (2 letters). This enables the user to setup
the device, get results or check parameters.
Example: DAD 143.x is connected via the RS 232 port to a PC / PLC system. You want to get the identity,
firmware version or net weight.
Remark: 
(LF) is not required and will be ignored by the device, if neccessary.
Master (PC / SPS) sends

4.3 Baud Rate
For baud rate setup use the command BR, see chapter 9.10.2.
4.4 Getting Started via service port RS 232
You will require:
•PC or PLC with a RS 232 communication port
•A load cell / scale with test weights or a load cell simulator
•A 12 to 24 VDC power supply capable of delivering approximately 200mA for each DAD 143.x
incl. the connected load cell(s).
•One or more DAD 143.x.
•A suitable ASCII communication software. **
Refer to the wiring diagrams in chapter 3.
**
You can easily communicate between a PC and a DAD 143.x using programs such as Procomm, Telemate,
Kermit, HyperTerminal or HTerm etc.
Additionally, the very powerful software DOP 4 (ver. 2.4.1.0 or higher) with graphical user interface and
oscilloscope function for the operating systems Windows XP/Vista/7/8/10 is available.
Hint:
A download of a new firmware version can be done with the program Protocol Firmware Loader PFL
ver. 1.00 or higher. The download has to be done via service port RS232 at a fixed baud rate of 115200.
More details of this procedure see chapter 12.

4.5 Getting Started Via Ethernet based Port, e.g. protocol for
EtherNet/IP
Following steps outlined below simplify the process of setting up a system for the first time.
•Connect the DAD to a suitable power supply.
•Connect a Windows PC to the DAD 143.x service port through a RS232 COM port or an USB to RS232
converter.
•A terminal program e.g. HyperTerm can be used for verifying or changing the setup of the DAD 143.x.
Default service port settings are: 115200 baud, 8 data bits, No parity and one stop bit.
•Or simply use the service commands for DAD 143.x of the EtherCAT Viewer, see below.
Screenshot of the EtherCAT Viewer ver. 1.2.0.0 Service Commands.
•Here you can edit the service parameters to the application needs.
•
•Connect one of the DAD Ethernet ports to your PC / PLC. The DAD 143.x needs for EtherCAT no
IP address. The DAD143.x has an Identification Value, e.g. 73 as shown above.
•To run the EtherCAT Viewer, you need to install on your PC a Npcap driver for your OS. You can find
•A Windows demo program for testing the EtherCAT functionality can be downloaded from
www.flintec.com
See screenshot of EtherCAT Viewer version 1.2.0.0 or higher on next page.
4.6 Downloading and Installing Npcap Free Edition
If you want to test the EtherCAT Viewer on your computer, you find support via the following link:
https://nmap.org/npcap/
You have to choose the required Installer for your OS.

•Press the butto -
Index, Current Value etc. per command.
For starting with another Ethernet based communication, the procedure is similar.
For detailed technical information of the different PLC bus systems, please see individual manuals for
#Profinet IO or #Ethernet/IP or #EtherCAT or #Modbus TCP.
