1. EM100 Module
1.1. Introduction
The Electronics Module, EM100-C, is a precise amplifier with integral 24-bit sigma-delta analogue-
to-digital converter for weighing and force measurements with strain gauge sensors. The module
includes an extensive selection of standard weighing and calibration functions for accurate static or
dynamic weighing applications. Its high-speed measuring rate, advanced filters and optimised
software functions are especially useful for check-weighing and other dynamic processes.
The EM100-C model is an approved accuracy class III module examined under OIML R51. The
measurement module forms part of an approved (‘legal-for-trade’) weighing system. The EM100-C
can be used in ‘legal-for-trade’ and industrial applications.
The device features a CAN interface with support for the CANopen protocol as well as full-duplex
RS-232 and RS-485 interfaces. A USB interface has been included for ease of use and is only for
configuration, setup and firmware upgrade.
Communication to the module is based on ASCII characters sent to a variety of serial interfaces
making it easy to connect to a PC, PLC or other devices. Setup of the module is simple using a
terminal emulation program or FDC application software (available from Flintec.com).

3. Getting Started
You will require:
•PC or PLC with RS-232, RS-485 or CANopen communication ports.
•Load-cell/scale with test weights or a load-cell simulator.
•+12VDC to +24VDC power supply capable of delivering approximately 200mA.
•A suitable ASCII communication software e.g. Hyper-Terminal, Putty, TeraTerm etc. or
Flintec Device Configuration (FDC) application software. Download the latest copy of FDC
from the Flintec website (www.flintec.com).
Note: The Flintec FDC application was developed in-conjunction with the ‘Peak System’ USB
to CAN adaptor. If using the CANopen interface AND the FDC application, only use the ‘Peak
System’ adaptor. See website below for more details. For all other interfaces listed above,
generic adaptors can be used in accordance with the manufacturer’s instructions and drivers.

The power supply is designed to accept a +12VDC or +24VDC supply. The power supply ground is
not the same potential as the comms or main chassis ground pins. Only use the appropriate power
and return pins for the supply, all comms and GPIOs pins to be referenced to the associated comms
or main chassis ground.

3.3.4. RS-485 Connection
The RS-485 network requires a 120Ω termination resistor at both the host end (EM100) and at the
furthest point in the network. The EM100 has a software selectable terminator built-in (see ‘STR’
command).
Note: For half-duplex (RS-485) operation tie RS-485 TX+ with RS-485 RX+ and RS-485 TX- with
RS-485 RX-.

3.3.5. CANopen Connection
Note: For the CAN network to operate properly, it is necessary to place a 120Ω termination resistor
at both the host end (EM100) and at the furthest point in the network. The EM100 has a software
selectable terminator built-in (see ‘CTR’ command).

3.4. Driver Check
During the first session, it may be necessary for the PC to install appropriate drivers. If using a CAN
adaptor or USB-to-serial converter, consult the manufacturer for instructions and latest drivers.
If using the USB CDC connection, the following driver from STMicroelectronics will need to be
installed. View the ST.com website for the latest revision:
http://www.st.com/en/development-tools/stsw-stm32102.html
An installation manual is available from the Flintec website (www.flintec.com).
