Note on termination of older BlueConnect Modules
Older modules have no slide switches on the board.
With older BlueConnect Modules, the termination of CAN bus and Modbus is done via
the configuration program (see 4 The BlueConnect Configuration Program).
Older modules are not terminated at the factory.
If there is no possibility to terminate the CAN bus via the configuration program:

4 The BlueConnect Configuration Program Software version: 1.13
4.1 Description
This operating manual describes the operation of the BlueConnect Configuration Program BlueConnect.exe.
The BlueConnect Configuration Program is enclosed1with every BlueConnect Module. For example, you can
use it (depending on the type of module and sensor) to read out sensor information, assign a Modbus address,
determine the internal amplification of the input signal, calibrate the sensor and display measured values.
The program runs under Windows 7 and newer. An installation is not necessary, the program starts by calling
up BlueConnect.exe.
4.2 Preparation
To enable your PC to communicate with a BlueConnect Module, you need a commercially available adapter
from RS485 to USB. The adapter creates a COM-port in the Windows system.
•The connection of the adapter is made at slot X3 at the contacts TX/RX- and TX/RX+.
•The power supply is made at slot X4 at the contacts GND and Power.
•In case of bus modules no other contacts may be assigned on the board.
4.3 Start BlueConnect.exe
The Select Port window (see below) opens. Here you have to select the right COM port for communication .
The program window opens:
Then select a Slave-ID2(quick select 1 to 16 or input 1 to 255),
or activate the ID Search (search from 1 to 255, the first match is selected).
Function buttons:
Opens the Sensor Info view in the function field.
Opens the Options view in the function field.
Opens the Calibration view in the function field.
No function on bus modules.
Opens the Measured Data view in the function field
1If not, contact GO Systemelektronik.
2Modbus address of the BlueTrace, factory preset is 1.

4.7 Calibration Sensor Modules
4.7.1 Calibration ISE, ORP and pH
A calibration compares the value pairs of the measured sensor raw values∗and allocated reference values
from calibration liquids. Here in addition you can set these values manually to calculate hypothetical calibra-
tions. These value pairs will be considered as points in a coordinate system. Through these points a curve will
be placed preferably exactly to a degree 1 up to a degree 5 polynomial, which is the calibration polynomial.
Example with degree 2 polynomial:
∗A raw value is the uncalibrated sensor mesasurement value.

4.7.1.1 The Calibration Table
There are two ways to enter the raw values:
•manual input – gives the possibility to calculate hypothetical calibrations
•measurement value transfer – current measured raw values for the actual calibration
The reference values are always entered manually. You can set up to 10 value pairs.
„measured value [ppm]“ is the reference value from a calibration liquid.
Manual input:
Unchecked:
Measure
After opening the calibration view the calibration table has
only one row. Click the cursor into the “raw value” cell and
enter the first raw value, click the cursor in
to the “measured
value” cell and enter the first reference value, or vice versa.
Measurement value transfer: Checked: Measure
After opening the calibration view the calibration table has
only one row. Click the cursor on the first row pushbutton:
as
long as the row pushbutton is checked the current
measurement raw value appears in the “raw value” cell.
Click the cursor into the “measured value cell” and enter
the first reference value.
To create a new row
, click the cursor into the last row with
an entry and press the ENTER-key.
To delete a row
, delete all row entries and click in another
row.
Order: Order means the degree of the calibration polynomial.
Click on one of the Order buttons 1 to 5 to get the best fit.
The graph of the calibration polynomial is displayed.
Writes the calculated coefficient values into the module memory after confirmation.

4.7.2 Calibration O2
The calibration of the O2 sensor is a two-point calibration (calibration degree 2 polynomial). One point is the
zero point, the other is determined by the saturation in air (100 %) or a pair of measured values from the
measurement value of the sensor and the measurement value of a reference measurement device in the same
measurement medium.
Start clicked: Measurement values are displayed every second.
Saturation calibration
Prerequisite: Setting O2 Unit % see 4.5 Options Sensor Module
1. Click on <Start>.
2. Hold the oxygen sensor in the air.∗
Wait at least 10 minutes until the displayed values are stable.
3. Click on <100% Calibration>.
4. The calibration is completed.
Reference calibration
Prerequisite: Setting O2 Unit mg/l see 4.5 Options Sensor Module
1. Click on <Start>
2. Immerse the oxygen sensor in your measurement medium and wait,
until the displayed values are stable.
3. Entering the oxygen content of the measurement medium according to the reference measur-
ing device
4. Click on <mg/l Calibration>.
5. The calibration is completed.
∗The galvanic cell for oxygen measurement is located at the bottom of the sensor body, the temperature sensor is near the
center. Therefore, a saturation calibration in the air can only be carried out when the entire sensor body has reached the tem-
perature of the ambient air. The larger the difference in temperature between the measuring medium and the ambient air, the
greater the time required for a temperature adjustment (30 minutes or more, if applicable).
The temperature adjustment can be accelerated by immersing the sensor in water, which has approximately the temperature
of the ambient air, before performing the saturation calibration.
Moreover, abrupt temperature changes (e.g., by direct exposure to the sun) must be avoided.

Appendix A – General Modbus Specification for GO Modbus Sensors
General The data to be transferred is always in a fixed frame and is defined as follows:
Address Function code Data CRC
1 byte 1 byte 0 … 252 byte(s) 2 bytes
Description Address: Sensor address (valid from 1 – 230)
Address 0 is the broadcast address and will not be answered.
Function code: Here you define whether parameters are to be read or written.
Data: e.g. from the master: Which parameters are requested?
e.g. from the slave: content of the requested parameters
CRC: CRC16
Data types
Standardized data types:
byte
(8-bit) and
register
(16-bit)
According to the Modbus specification, a register always transmits
the high-byte first, followed by the low-byte.
Extended data types:
32-bit integer
and
32-bit float
are transmitted as 2 consecutive 16-
bit
registers. 64-bit integer and 64-bit float are transmitted as 4 con-
secutive 16-
bit registers. The format of the float number corresponds
to the IEEE standard 754.
The transfer sequence of the registers is not specified. In most applications, however, it is as follows:
32-bit numbers Reg_L (bit 15..0) Reg_H (bit 31..16)
HByte LByte HByte LByte
64-bit numbers Reg_L (bit 15..0) Reg_H (bit 31..16) Reg_L (47..32) Reg_H (63..48)
HByte LByte HByte LByte HByte LByte HByte LByte

Transmission parameter RTU Modus 9600 Baud 8 data bits no parity bit 1 stop bit
Register
Modbus provides to store the data in different registers. Each register stores 2 byte. A difference is made in the
following registers:
Register number
Register address Type Modbus designation Description
– read / write Discrete Output Coils Discrete outputs
– read only Discrete Input Contacts Discrete inputs
0x0100 – 0x0FFF write only
(except IO) Input Registers Input register, Measurement
values of the sensors
0x0000 – 0x00FF read / write Output Holding Registers Hold register for parameters,
Device configuration, etc.
Slave table Each
slave has a parameter table and an actual value table. From these tables it can be
seen which parameters can be found under which addresses.
Coils should not be used, I/Os are managed via the parameter table.
