2. Introduction

Speed meters of series SD, SA and SR have been designed to close a gap with multiple speed measuring applications, which cannot be accomplished by normal industrial tachometers.
A continual demand for increasing production speeds and higher precision at the same time results in counting frequencies exceeding the conventional frequency range.
Particularly with fast running machines it is most important to also get fast response of the switching outputs or the analogue output.
Many applications require to evaluate the signals of two incremental measuring systems, and to compare the results with respect to the sum or the difference or the ratio of the two speeds. The latter is e.g. required to indicate the diameter of a winding roll by sensing the line speed and the roll rpm.
Other applications with food processing or process technology need to record the speed in a reciprocal way (i.e. baking or processing time calculated from the actual speed)
And still there exist applications where the use of traditional thumbwheel switches offers real advantages compared to keypad and menu operations.
These are some of the reasons why the new indicator series SD / SA / SR have been designed.
This manual at first provides all basic instructions for operation of the
counter models presented in the previous chapter
For operation of relay outputs and thumbwheel switches (if applicable)
please observe the supplementary instructions given in the appendix
For easy PC setup and PC communication with SD and SA counters,
please use our “OS32” operator software (free of charge, download from our homepage www.motrona.com
Where you like to have free serial access to the unit by PLC or IPC or by a
remote operator terminal, please observe the serial protocol details described in our separate manual “Serpro”
Subsequently the manual uses the expression SD340 as a replacement for
all available models. However, statements are fully valid for the other models too, except where especially remarked.

*) 120 mA and 150 mA are per encoder, i.e. total maximum currents are 240 mA and 300 mA

3.1. Power Supply

The SD340 counter accepts both, a 17 – 40 volts DC power or a 24 volts AC power (+/-10%) for supply via terminals 17 and 1. The current consumption depends on the level of the input voltage and some internal conditions; therefore it can vary in a range from 100 – 200 mA (aux. currents taken from the unit for encoder supply not included).

3.2. Auxiliary Outputs for Encoder Supply

Terminals 2 and 18 provide an auxiliary output with approx. +5.2 volts DC (300 mA totally). Terminals 3 and 19 provide an auxiliary output with approx. +24 volts DC (240 mA totally)

3.3. Impulse Inputs for Incremental Encoders

All input characteristics of the impulse inputs can be set by the parameter menu, for each of the encoders separately. Depending on the application the unit can accept single channel information (input A only without direction signal) or dual channel signals (A = step and B = direction) or quadrature information (A / B, 90°). The following settings are possible:
Symmetric input (differential A, /A, B, /B) according to RS422 standard TTL inputs at a level of 3.0 to 5 volts (differential, with inverted signal) TTL inputs at a level of 3.0 to 5 volts (single-ended) *) HTL signals at a 10 – 30 volts level
(alternatively differential with inverted signals A, /A, B, /B, or single-ended A, B only)
Impulses from photocells or proximity switches etc. providing a HTL level (10 – 30 volts) Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see “Special parameters F08”
All encoder input lines are internally terminated by pull-down resistors ( 8,5 kΩ ). Where encoders with pure NPN outputs are used, corresponding pull-up resistors must be available inside the encoder or externally to ensure proper function (1 kΩ ... 3,3 kΩ).

3.4. Control Inputs Cont.1 – Cont.4

These inputs can be configured for various remote functions as described under 6.2.4. All control inputs require HTL level. They can be individually set to either NPN (switch to -) or PNP (switch to +) characteristics. For applications where edge-triggered action is needed, the menu allows to set the active edge (rising or falling). Control inputs also accept signals with Namur (2-wire) standard.
For reliable operation the minimum pulse width on the control inputs should be 50 µsec.

3.5. Switching Outputs K1 – K4

RS 232
RS 485
SD340 provides four presets and outputs with programmable switching characteristics. K1 – K4 are fast-switching and short-circuit-proof transistor outputs with a switching capability of 5 – 30 volts / 350 mA each. The switching voltage of the outputs must be applied remotely to the Com+ input (terminal 29)

3.6. Serial Interface

The serial RS232/RS485 interfaces can be used for the following purposes:
Set-up of the unit by PC (if desirable), by means of the OS32 PC software Change of parameters during operation Readout of actual counter or other values by PLC or PC
The figure below explains how to connect the SD340 unit and a PC using the standard Sub-D-9 serial connector, and how to connect the RS485 terminals to a PLC. Details about serial communication are shown in chapter 9.

3.7. Fast Analogue Output (SA models only)

An analogue output is available with all SA models, providing a voltage output of +/- 10 volts (Load = 2 mA), and a current output of 0 – 20 mA or 4 – 20 mA (load = 0 – 270 Ohms). All output characteristics like beginning of conversion range, output swing etc. are freely programmable via menu. The response time of the analogue output depends on the mode of measuring and the sampling times used. The analogue resolution is 14 bits.
Please note that extensive serial communication with the unit may temporary increase the analogue response time.

4. Operating Modes of the Counter

For best survey, all parameters of the unit are arranged in 13 expedient groups, named “F01” - “F13”. Depending on the application, only a few of these groups may be important, while all other groups may be irrelevant for your specific application.
All details about configuration and function of the parameters can be founds in chapter 6. Practical examples for settings are shown in chapter 7.
This section describes possible applications and operating modes of the unit.
The operation mode can be set under parameter group F02, parameter # F02.004.
It is possible to cycle the display between all reading modes shown in the following
function tables, by pressing one of the front keys or by using one of the control inputs (you must have assigned the "display scrolling function" to one of the keys or the inputs under menu F05 to activate the scrolling of the display).
LED L1 (red) and L2 (yellow) indicate which of the values is actually visible in display
L1 on: the speed of encoder 1 is displayed L2 on: the speed of encoder 2 is displayed L1 and L2 on: the combined value [encoder1]*[encoder2] is displayed.
LEDs shining continuously indicate: actual measuring value.
LEDs blinking slowly indicate: minimum value (since last reset of the min/max memory). LEDs blinking fast indicate: maximum value (since last reset of the min/max memory).
Scrolling of the display from one reading mode to another will not affect the function
of the preselection outputs K1 – K4
The analogue output (models SA) can be assigned to any of the readings accessible in
the display, by a special parameter. Scrolling of the display from one reading mode to another will not affect the analogue output.
With all operating modes the evaluation of the input frequencies occurs fully
separately with use of individual scaling factors. Please observe that only integer results after the scaling operations, but no decimal positions will appear in the display. Where you like to display your result with decimals, please scale your value correspondingly higher (by factor 10, 100 or 1000) and then use a decimal point to receive the desired display value (see examples under 7.1)
With all encoders providing information about the direction of rotation
(e.g. quadrature encoders A/B/90°), the unit will also display a sign (positive with A leading B and negative with B leading A). Preselection values can be set for response to absolute values only (no consideration of the actual sign), or for response to the signed value. With models SA the analogue output will also change the +/- polarity in accordance with the actual sign.
All combinations [encoder1] * [encoder2] are calculated straightaway according to the
individual operating mode and the scaling factor of each channel. Please take care that the results to combine are scaled with proper and compatible dimensions (don't compare apples and oranges)
You can choose from the following operating modes:
Operating Mode
0
Single mode, evaluation of encoder 1 only
1
Dual mode, individual evaluation of encoder 1 and encoder 2
2
Sum mode, [speed of encoder1] + [speed of encoder2]

F02.004
Your choice of operating mode will decide how in general the two encoder frequencies have to be treated. It will not affect the scaling or the measuring characteristics or the final presentation of the result.

Both inputs, encoder 1 and encoder 2, are active. Both speeds are multiplied to form the product, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02.
Besides the actual speeds and the multiplication result, the unit also records minimum and maximum values of the product.
Preset K1 is related to the absolute speed of encoder 1. Preset K2 is related to the absolute speed of encoder 2. Presets K3 and K4 are related to the product of both speeds (encoder 1 x encoder 2)

Both inputs, encoder 1 and encoder 2, are active. The unit calculates the ratio of the two speeds, with consideration of the individual scaling of each channel. The final result can once more be scaled into user-friendly engineering units by means of the special scaling parameters in parameter group F02 (conversion factor K = F02.09 : F02.08), see figure below*).
F02.004 = 5 calculates [encoder1] : [encoder2] F02.004 = 6 calculates [encoder2] : [encoder1]
Besides the actual speeds and the ratio the unit also records minimum and maximum values of the ratio.
Preset K1 is related to the absolute speed of encoder 1. Preset K2 is related to the absolute speed of encoder 2. Presets K3 and K4 are related to the ratio of both speeds

*) The unit presents the ratio of the two speeds as an integer number only, e.g. if both speeds are equal,
the unit would just display "1". To display a ratio with decimal positions like 1.0 or 1.00 or 1.000 etc. it is necessary to follow one of these hints: a. scale the speed used as numerator by a factor of 10 or 100 or 1000 higher than the denominator, or b. set parameters F02.009 (multiplier) and F02.008 (divider) with a ratio of 10, 100 or 1000

5. Keypad Operation

PROG

ENTER
An overview of all parameters and explanations can be found under section 6.
The menu of the unit uses four keys, hereinafter named as follows:
Key functions depend on the actual operating state of the unit. Essentially we have to describe three basic states:
Normal operation General setup procedure Direct fast access to presets and set values

5.1. Normal Operation

In this mode the unit operates as a counter according to the settings defined upon setup. All front keys may have customer-defined functions according to the specifications met in the keypad definition menu F05 (e.g. scrolling of the display, Reset, Inhibit etc.)

5.2. General Setup Procedure

The unit changes over from normal operation to setup level when keeping the key down for at least 2 seconds. Thereafter you can select one of the parameter groups F01 to F13.
Inside the group you can now select the desired parameter and set the value according to need. After this you can either set more parameters or return to the normal operation.
The adjoining sequence of key operations explains how to change Parameter number 060 of group F06 from the original value of 0 to 8

5.5. Code Protection against Unauthorized Keypad Access

Parameter group F07 allows to define an own locking code for each of the parameter menus. This permits to limit access to certain parameter groups to specific persons only.
When accessing a protected parameter group, the display will first show “CODE” and wait for your entry. To continue keypad operations you must now enter the code which you have stored before, otherwise the unit will return to normal operation again.
After entering your code, press the ENTER key and keep it down until the unit responds. When your code was correct, the response will be “YES” and the menu will work normally. With incorrect code the response will be “NO” and the menu remains locked.
In order to avoid inadvertent misadjustment upon commissioning, parameter groups F07 (keypad protection), F08 (special functions) and F11 (Linearization) are already protected by factory setting. For access please use code 6078

5.6. Return from the Programming Levels and Time-Out Function

At any time the PROG key sets the menu one level up and finally returns to normal operation. The same step occurs automatically via the time-out function, when during a period of 10 seconds no key has been touched.
Termination of the menu by automatic time-out will not store new settings, unless they have already been stored by the PROG key after editing.

5.7. Reset all Parameters to Factory Default Values

Upon special need it may be desirable to set all parameters back to their original factory settings (e.g. because you have forgotten your access code, or by too many change of settings you have achieved a complex parameter state). Default values are indicated in the parameter tables shown later. To reset the unit to default, please take the following steps:
Switch power off
Press
Switch power on while you keep down both keys
Where you decide to take this action, please note that all parameters and settings will be lost, and that you will need to run a new setup procedure again.

*) Important Hints:
a. With irregular and out-of-round motion-sequence it may be advantageous to use a
fixed number of input pulses for sampling, instead of a sampling time. This method is suitable to stabilize or suppress undulation of the display (e.g. with unbalanced and eccentric movements) because an overall average of one undulation is formed
b. It is advisable to always use the synchronized mode whenever measuring speed
ratios or percentaged speed difference. Otherwise unacceptable variation of the display may occur, caused by the different timing of the two speed values
With the synchronization set to ON, parameters "Sampling Time1" (or "Sampling Pulses") as well as "Wait Time1" are used conjointly for both encoders and the corresponding settings for encoder 2 are inoperative. The response time of the unit depends in each case on the lower one of the two input frequencies
c. Where the low-pass filter is used to limit the input frequency, higher frequencies
than indicated will no more be evaluated correctly

then this function can be used to temporary substitute the real input frequency of encoder 1 by a virtual frequency according to setting.

F03.031 Start-up Mode1: Start-up delay for the switching outputs *) 0 ... 10 0
The start-up delay is suitable to temporary suppress the control function of a switching output (in general for monitoring of a minimum value). The machine then is allowed to start up first, prior to activation of the alarm. The start-up delay becomes active upon power-up of the unit or after the unit has detected "standstill". The following settings are available (always for encoder 1):
0 = Start-up delay OFF 1 = timed delay: 001 second 2 = timed delay: 002 seconds 3 = timed delay: 004 seconds 4 = timed delay: 008 seconds 5 = timed delay: 016 seconds 6 = timed delay: 032 seconds 7 = timed delay: 064 seconds 8 = timed delay: 128 seconds 9 = automatic delay until first exceeding of the minimum value

Time1"), the unit will continue waiting until "Standstill Time1" has elapsed and then finally report "standstill of encoder 1".
*) When you use the start-up delay function with combined modes [encoder1] * [encoder2], always
the longest of both settings will be responsible for start-up

F04.042 Set Value2: Preset value to simulate fixed input frequency -199 999
When you have assigned the function "Set Frequency 2" to any of the front keys or the control inputs (see parameter group F05),
999 999 (x.xx Hz)
...
then this function can be used to temporary substitute the real input frequency of encoder 2 by a virtual frequency according to setting. This e.g. allows simulation of the unit and all functions / outputs while the machine itself is in standstill. When the Set Value2 is set to 2000 the frequency value corresponds to 20.00 Hz.
0
*) Practical setting examples for these display modes can be found in chapter 7.
**) For setup and scaling of the unit please always use decimal format first and
set your display to full seconds. When you find that all other functions work fine, then change over to the desired clock format.
F04 Range Default
F04.043 Start-up Mode2: Start-up delay for the switching outputs *) 0 ... 10 0
The start-up delay is suitable to temporary suppress the control function of a switching output (in general for monitoring of a minimum value). The machine then is allowed to start up first, prior to activation of the alarm. The start-up delay becomes active upon power-up of the unit or after the unit has detected "standstill". The following settings are available (always for encoder 2):
0 = Start-up delay OFF 1 = timed delay: 001 second 2 = timed delay: 002 seconds 3 = timed delay: 004 seconds 4 = timed delay: 008 seconds 5 = timed delay: 016 seconds 6 = timed delay: 032 seconds 7 = timed delay: 064 seconds 8 = timed delay: 128 seconds 9 = automatic delay until first exceeding of the minimum value
10 = external suppression by means of a control input
F04.044 Standstill Time2: Time for definition of "standstill" of encoder 2 0.00 ... 99,99
After the unit has detected "frequency = 0" (see parameter "Wait
sec.
0.00
Time2"), the unit will continue waiting until "Standstill Time2" has elapsed and then finally report "standstill of encoder 2".
*) When you use the start-up delay function with combined modes [encoder1] * [encoder2], always
the longest of both settings will be responsible for start-up

*)
*) mirror of positive range
x-registers are to set the numeric value that the unit would display without
linearization
y-registers are to set the numeric value that should be displayed instead,
i.e. the (y3) setting will replace the (x3) display value
between the interpolation points the unit automatically uses linear
interpolation
(x0)= 0 (y0)= 0
(x15)= 1000 (y15)= 800
x
(x0)= -1000 (y0)= 900
(x8)= 0 (y8)= 750
(x15)= +1000 (y15)= - 600
x- registers have to use continuously increasing values, e.g. the lowest display
value must be set to register x0, and the highest display value must be set to x16
Independent of the selected linearization mode, the possible setting range of
all registers x0, y0, … x16, y16 is always -199999 … 999999.
For measuring values outside of the defined linearization range, please note:
If the measuring value is lower than (x0), the linearization result will always be (y0).
If the measuring value is higher than (x15), the linearization result will always be (y15).

7. Practical Examples for Setup and Scaling

For proper scaling of the unit is mandatory to respond to the following questions:
Which input frequency (Hz) will the encoders produce at a typical speed? Which numeric value do we intend to display at this typical speed?
(sequence of numbers including the decimal positions)
Is the display characteristics proportional (speed) or reciprocal (time)?
The subsequent settings refer to the illustrations shown in chapter 4.

7.1. Settings for the Example a) of Chapter 4.1 (Speed Display)

Machine specifications: Calculations: Relevant parameters:
Encoder: TTL A, /A, B, /B 4096 ppr.
Measuring wheel: Circumference = 500 mm (diameter = 159,2 mm)
Expected Line speed: 0 ... 300 meters/min Desired display value: 0 ... 300,0 m/min (one decimal position)
With a speed of 300 m/min the measuring wheel will rotate at 600 rpm.
With a 4096 ppr encoder we will get 600 x 4096 = 2 457 600 Imp./ min equal to 40 960 Imp /sec. (Hz)
This means at maximum speed of 300 m/min the encoder frequency is 40 960 Hz.
We expect a display value of 3000 (to display 300.0)
F02.004 0 F02.0005 1 F03.022 0 F03.024 0,100 (assumed)
i.e. display cycle = 0.1 sec. F03.025 0,10 (display zero with f < 10 Hz) F03.027 40960 F03.028 3000
(= 300.0 with a decimal point) F03.029 0

7.2. Settings for the Example b) of Chapter 4.1 (Baking Time)

Machine specifications: Calculations: Relevant parameters:
Proximity switch: Standard PNP 3-wire type
Sensed pinion: 16 teeth 70 rev. of the pinion = 1 meter of travelling distance
Furnace length: 60 m
Range of baking times: from 10 min. up to 2 h
Desired display format: 01h : 59min : 59sec
To run over the full furnace distance of 60 meters, the proximity will generate a total number of impulses of 60 x 70 x 16 imp. = 67200 impulses totally
With maximum speed we expect a transition time of 10 min. equal to 600 sec.
With 67200 impulses in 600 seconds our frequency corresponds to 112 Hz

7.3. Settings for Example "Differential Speed" of Chapter 4.4

Machine specifications: Calculations: Relevant parameters:
Both encoders: 1024 ppr quadrature A / B / HTL 24 V
Circumferences (rolls): all rolls should have the same circumference of 350 mm
Speeds: Maximum speed on both conveyors is 200 m/min
Desired display: Differential speed with two decimal positions (format +/-99.99 m/min)
Wit a maximum speed of 200 m/min and a roll circumference of 0.350 m we will get a roll rpm of 200 m/min : 0,350 m = 571.43 rpm
This results in encoder frequencies of
571.43 x 1024 Imp/min = 585 143 Imp./min = 9752.4 Imp./sec. (Hz)

all = 2
both = 1000
(no re-scaling necessary)
It is advisable to synchronize
both measuring channels
whenever we use combined
display results
both = 1
For correct calculation of the
difference we must ensure that
both speeds have the same
direction (both positive or both
negative), i.e. either
[+Geber1] - [+Geber2] or
[-Geber1] - [-Geber2]
both = 0.500 (assumed), i.e.
display cycle = 0,5 sec.
both = 0,20 (assumed), i.e.
speed = 0 with f < 5 Hz
both = 9752 *)
both = 20 000 *)
(will appear as 200.00 since we
desire to have two decimal
positions)
both = 0
*) With high accuracy demand we are free to increase the frequency setting tenfold. This will allow to
also consider the remaining decimal position of our calculation (i.e. F03.027 = 97524). In order to maintain the proportionality we have then to increase also the desired display value by factor 10 (i.e. F03.028 = 200 000).

cycles. As a result, after the first sampling period we can only see 12.5% (1/8) of the jump and only 7 cycles later we would come up to 100%. However, since the whole jump duration is only 6 cycles long, the display already starts to step back to the previous value before we reached the full jumping level
Time Constant of the exponential filter always equals 2 sampling times, we reach 63% of the jumping level after 20 msec.

8. Appendix for models SD/SA/SR 6xx

Thumbwheel set 2
Thumbwheel set 4

8.1. Relay Outputs

All available models are shown in section 1. While models SD 3xx provide high-speed transistor outputs only, all models SD 6xx provide four additional relay outputs, operating in parallel to the high-speed transistor outputs K1 – K4.
All electrical connections of 6xx models are fully similar to the 3xx models, except that with 6xx models the back plane is equipped with an additional 12-position terminal strip.

8.2. Front Thumbwheel Switches

Moreover, the models shown below provide thumbwheel switches on the front panel, for simple and easy setting of preselection levels. Every row allows in maximum 9 decades and one blank field for separation. The customer is free to specify any desired combination and number of decades individually, which is not wider than totally 10 spaces. As an example, with model 642 it is possible to specify
“Set1 = 3 decades, Set2 = 6 decades”, or e.g. “Set1 = 8 decades” etc.
Where your order does not clearly state a different array of the thumbwheels, the units will be supplied with 2 x 4 decades respectively 4 x 4 decades
Models 642 can have Models 644 can have max. 2 switch sets on front max. 4 switch sets on front

The following parameter settings apply for units with thumbwheel switches only and are not relevant for all other models:

8.3.1. Read and update thumbwheel switch settings All actual thumbwheel settings are automatically considered when the unit is powered up.

However, changes during normal operation will not be considered, unless upon special remote command. This can either be the actuation of one of the front keys, or a command signal to one of the control inputs.
Please see section 6.2.4 with the parameter group F05.
It is a “must” to assign the function "16" to at least one of the front keys or one of the control inputs. These functions will read the settings of the front switches. Otherwise there will be no way to activate changes of the switch settings during operation.

8.3.2. Positive or negative sign of thumbwheel settings In general and as a default, the front thumbwheel settings are assumed to have a positive sign.

Some applications may however require that one or the other setting should be interpreted as a negative value. Parameter F06.071 allows assigning negative signs to any of the front thumbwheels, following a binary schema as shown in the table below:

8.3.3. Assignments between thumbwheels and switching outputs In general and as a default, thumbwheel switch set No.1 refers to output K1; thumbwheel

switch set No.2 refers to output K2 etc. This may be convenient for most of the applications, but also cause inconvenience with some operating modes of the counter.
As an example, when using the “Sum Mode” (see section 4.3), the outputs K1 and K2 are firmly attached to the encoder1 counter and outputs K3 and K4 are firmly attached to the sum of encoder1 and encoder2.
From this follows that, if you use a counter model with two sets of thumbwheels only

(thumbwheel set 1 and thumbwheel set 2), you would only have preselections referring to encoder1, but no thumbwheel access to the sum.
To avoid such kind of limitations, parameter F06.072 allows free assignments between any of the thumbwheel switch sets (switch1 to switch4, see previous figure) and any of the four outputs (K1 to K4)

9. Appendix: Serial Communication Details

Serial communication with the counter can be used for the following purposes:
PC setup of the counter, using the OS32 Operator software Automatic and cyclic transmission of counter data to remote devices like PC, PLC or
Data Logger Communication via PC or PLC, using the communication protocol This section describes the essential and basic communication features only. Full details are
available from the special SERPRO manual.

9.1. Setup of the Counter by PC

Connect the counter to your PC as shown in section 3.6 of this manual. Start the OS32 Operator software. After a short initializing time you will see the following screen:
If your screen remains empty and the headline of your PC says „OFFLINE“, select „Comms“ of the menu bar and check your serial communication settings.
The edit field on the left shows all actual parameters and provides full editing function. The „File“ menu allows to store complete sets of parameters for printout or for download to a counter.
When editing parameters, please use the ENTER key of your PC after each entry, to ensure storage of your data to the counter.

Set any cycle time unequal to zero to parameter F10.110. Set the serial access code of the register you would like to transmit to parameter F10.111. In theory you could transmit any of the internal registers by serial link, however only the following registers make really sense:
Dependent on the setting of parameter F10.109 the unit transmits one of the following data strings, under cycle control of the timer: (xxxx = counter data*, LF = Line Feed <hex. 0A>, CR = Carriage Return <hex 0D>)
*) Leading zeros will not be transmitted

9.3. Communication Protocol

When communicating with the unit via protocol, you have full read/write access to all internal parameters, states and actual counter values. The protocol uses the DRIVECOM standard according to DIN ISO 1745. A list with the most frequently used serial access codes can be found in the previous section.
To request data from the counter, the following request string must be sent:
AD1 = Unit address, High Byte AD2 = Unit address, Low Byte C1 = Register code to read, High Byte C2 = Register code to read, Low Byte ENQ = Control character (Hex 05)
The example shows how to request for transmission of the actual encoder 1 speed (register code :9), from a unit with unit address 11:
Upon correct request, the counter will respond:
STXC1C2x x x x x x x
ETX
BCC
STX = Control character (Hex 02)
EOT
AD1
AD2
STXC1C2
x x x x x x x
ETX
BCC
EOT = Control
character (Hex 04)
C1 = Register code to read, High Byte C2 = Register code to read, Low Byte xxxxx = Counter data *) ETX = Control character (Hex 03) BCC = Block check character
*) Leading zeros will not be transmitted
The Block-Check-Character represents the EXCLUSIVE-OR function of all characters from C1 to ETX (both comprised).
To write to a parameter, you have to send the following string:
AD1 = Unit address, High Byte AD2 = Unit address, Low Byte STX = Control character (Hex 02) C1 = Register code to write, High Byte C2 = Register code to write, Low Byte xxxxx = Value of the parameter ETX = Control character (Hex 03) BCC = Block check character
Upon correct receipt the unit will respond by ACK, otherwise by NAK. Every new parameter sent will first go to a buffer memory, without affecting the actual measuring process. This function enables the user, during normal measuring operation, to prepare a complete new parameter set in the background.
To activate transmitted parameters, you must write the numeric value “1” to the “ Activate Data“ register. This immediately activates all changed settings at the same time.
Where you like the new parameters to remain valid also after the next power up of the unit, you still have to write the numeric value “1” to the „Store EEProm“ register. This will store all new data to the EEProm of the unit. Otherwise, after power down the unit would return with the previous parameter set.

9.4.1. Communication Commands

These commands have to be sent to the unit every time after one or several new parameters have been transmitted, in order to activate or to store the new values. Both commands are "dynamic", i.e. it is sufficient to just send the data value "1" to the corresponding code position.
Example: send the command "Activate Date" to the unit with Unit No. 11:
ASCII EOT 1 1 STX 6 7 1 ETX BCC
Hex 0 4 3 1 3 1 0 2 3 6 3 7 3 1 0 3 3 3

9.4.2. Control Commands

*) Sending data value "1" to the corresponding location will switch the command
persistently ON until sending again the data "0" to the same location **) Sending data value "1" to the corresponding location will switch the command
ON and the bit will automatically reset to 0 after execution
Example: Switch on the hardware keypad lock (disable keypad of unit No. 11):
Switch off the hardware keypad lock (enable keypad of unit No. 11 again)
