2.2 Command format
Commands are not case-sensitive, so either format can be used for input.
Every command input must be completed with a delimiter. This can either be a line feed (LF)
or a semi-colon (;).
If a delimiter is all that is sent to the DIS, the DIS input buffer is cleared.
The data provided in round brackets () for the commands are mandatory and must be part of
the command input. Parameters in pointed brackets <> are optional and do not have to be
provided. The brackets themselves are not part of the input.
Text must be enclosed in quotes.
With numeric input, preceding zeroes are suppressed.
Responses are output in ASCII characters and end with LF.
Each command consists of the command shortform, one or more parameters and the
delimiter.
 

LF: Line Feed (lf = 0a hex)
Example: MSV?;
A measured value is output following this command.
All ASCII characters<20H (Blank) can be used between the command shortform, parameters
and delimiter.
The following characters can be used for commands and parameters:
’ ’ ’+’ ’-’ ’.’ ’,’ ’”’ ’0’ ...’9’ ’A’...’Z’ ’a’...’z’
The input range for an input string (PST command) comprises: 0x1fhex < char < 0x7fhex. In
this case, the string is enclosed with ”...String...”.
NOTE
When the master has sent a command sequence (query), the reply must be waited for
before the next query is sent.
When the master has sent a command sequence (input), the next query or command can be
sent at the earliest after 10 milliseconds.
14 DIS2116 - Communication commands

2.3 Response to commands
NOTE
Note on the response times of the DIS:
The DIS response times indicated in the command description do not include the
transmission time of the command to the DIS or the transmission time of a response from the
DIS.
2.3.1 Response to inputs
The DIS COM2 computer interface is an RS-232 interface.
Following a valid input, the DIS responds with 0CRLF.
Following an invalid input or syntax error, with ?CRLF.
Example:
 

When the master has sent a command sequence (query), the reply must be waited for
before the next query or command is sent.
NOTE
If the parameter is a legal-for-trade parameter and the legal for trade mode is
switched on, this parameter is not changed and the response to the command is ?crlf.
CRLF: carriage return, line feed (cr = 0d hex, lf = 0a hex)
DIS2116 - Communication commands 15

2.3.2 Response to parameter queries
A parameter query is input with a command to which a question mark is added.
A parameter query is always responded to in ASCII format. The delimiter is a Line Feed (LF
= 0A hex).
The output length of a query is always constant for every command.
Example:
 

When the master has sent a command sequence (query), the reply must be waited for
before the next query or command is sent.
2.3.3 Responses to incorrect or unknown commands
The DIS responds with ?crlf when a command is incorrect or unknown.
16 DIS2116 - Communication commands

2.4 Output types for measured values
The response to measured value queries (MSV?) is a ±8 digit measured value including
decimal point followed by one blank and 4 characters unit.
Examples:
 

LF: Line Feed ( = 0a hex) , CR: Carriage Return ( = 0d hex)
The measurement output delimiter is always a Line Feed.
2.5 Password protection parameters
DIS password protection includes important settings for the characteristic curve of the scale
and its identification. Commands with password protection are only activated once the
password is entered. Unless the password is not entered with the command SPW this
command will not be executed. A query is always possible.

3 Individual command descriptions
3.1 Interface commands
To set up communication between the DIS and the computer, the interface must be
configured. The following commands are available in the DIS for setting up the interface and
selecting the transmission format:
• COM1 Baud rate setting BD1
Communication (2, 4-wire operation) TWC
• COM2 Baud rate setting BD2
Parity setting PA2
Function FC2
• COM3 Baud rate setting BD3
Parity setting PA3
Function FC3
Protocol PT3
• COM4 Baud rate setting BD4
Parity setting PA4
Function FC4
Protocol PT4
Serial interface characteristics:
 

The asynchronous interfaces of the DIS are serial interfaces, i.e., data are transferred bit by
bit, one after the other and asynchronously. Asynchronous means that the transmission
works without a clock signal.
A start bit is set before each data byte. Then come the word bits (D0...D7), one or no parity
bit(s) for the transmission check and a stop bit.
20 DIS2116 - Communication commands

Fig. 1: Composition of a character
As the data are transmitted one after another, the transmission speed must match the
reception speed. The number of bits per second is called the baud rate.
The exact baud rate of the receiver is synchronized with the start bit for each character
transferred. Next come the data bits, which all have the same length. When the stop bit is
reached, the receiver goes into the wait state until it is reactivated by the next start bit.
The number of characters per measured value is fixed at 13 characters (11 characters
measured value and 2 characters CRLF).

3.2 Scale characteristic curve and output scaling
 

The DIS2116 is solely suitable for operation with digital load cells (e.g. C16i). With these load
cells, the factory settings are stored in the load cells themselves.
An unloaded digital load cell delivers a measured value of 0 and a digital load cell loaded
with the maximum capacity delivers a measured value of 1000000 internal digits.
The relationship between internal digits and weight units, e.g. kg, t, etc. is implemented via
the user characteristic curve (LDW, LWT)
The user characteristic curve is set with the commands described in this section:
Setting the characteristic curve
The DIS works with the factory characteristic curve set in the load cells. This factory
characteristic curve must not be changed.
A second characteristic curve (LDW, LWT) is available for the adjustment of the scale.
The gravitational acceleration correction is, in this case, activated via the command GCA
and GDE , when the site where the scale was adjusted is different to where it is now installed
and when the gravitational acceleration factors are not identical.
DIS2116 - Communication commands 35

G Correction Factor
(G factor correction, calibration site)
 

Relevant to
verification
Yes
 

Note: ( ) Required parameters, < > optional parameters on parameter input.
DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
This command is used to correct for the effect of gravitational acceleration when the site
where the scale is adjusted is not identical to the installation site and when the gravitational
acceleration factors (g) are different.
Parameter description:
When queried, the value is output in 6 digits with a positive or negative sign (e.g. 098102
CRLF).
The correction is deactivated with GCA = GDE.
Calculation of the internal correction factor:
The internal GF parameter is automatically reset (GDE := GCA) when
• the characteristic curve LDW / LWT is measured again.
Typical input example:
Adjustment site = Darmstadt " g = 9.8104
Installation site = Tokyo " g = 9.7977
GF = 1.001285

Note: ( ) Required parameters, < > optional parameters on parameter input.
DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
When queried, the value is output in 6 digits with a positive or negative sign (e.g. 098104
CRLF).
The correction is deactivated with GCA = GDE.
See command GCA.
You can adapt the DIS characteristic curve with the command pair LDW/LWT to your
particular requirements.
Using the command CWT , the user characteristic curve can also be set with partial load.
NOTE
The characteristic curve commandsLDW and LWT must be input or executed in the following
order: LDW and then LWT. The input data are only offset when both these parameters have
been entered or measured in pairs.
After the scale is adjusted, the range LDW → LWT is assigned to the following number

DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
When measuring, the actual input signal (e.g. scale not loaded, but with deadload weight) is
assigned to the internal measured value, the output value 0 digits.
Parameter description:
When queried, the value is output in 7 digits with a positive or negative sign (e.g. -0000246
CRLF).
The user characteristic curve is deactivated at LDW = 0 and LWT = 1000000.
The LDW value is not converted via NOV .
There are two options for zero point adjustment:
LDW
DIS2116 - Communication commands 39

1. Adopting the zero point of the user characteristic curve with LDW
(reaction time < 4.2 s):
The scale is not loaded. Adopt the zero point with the command LDW;
The transducer electronics measure the input signal between
3 mV/V or the zero load of
the scale, store the measured value and offset it, but only after the parameter for LWT is
entered.
2.Manual input of the user curve zero point via LDW (reaction time < 10 ms):
Use the command LDW to enter the value for the zero point of the scale. The
value entered is stored, but only offset after the parameter for LWT is entered.
If the LDW/LWT adjustment is not being executed with 100 % of the input signal, the CWT
value (calibration weight) must be set first.

the internal measured value, the output value 1000000 digits.
Parameter description:
When queried, the value is output in 7 digits with a positive or negative sign (e.g. -0950246
CRLF).
The user characteristic curve is deactivated at LDW = 0 and LWT = 1000000.
The LWT value is not converted via NOV .
LWT
DIS2116 - Communication commands 41

Adopting the nominal value of the user characteristic curve with LWT
(reaction time < 4.2 s):
1. The scale is loaded at max. capacity.
2. Using the command LWT;, the AED/FIT measures an input signal between
3.0 mV/V or
at max. capacity and offsets this measured value with the previously entered value for
LDW to a new characteristic curve.
Manual input of the user curve full scale via LWT (reaction time < 10 ms):
1. Enter the LDW value.
2. Use the command LWT to enter the measured value for the max.
capacity.The value entered is stored and offset with the previously measured or entered
LDW value.
If the LDW/LWT adjustment is not being executed with 100 % of the input signal, the CWT
value (calibration weight) must be set first.
Manual input of nominal value via LWT:
1. Use the command SPW to enter your password.
2. Set the legal-for-trade switch to LFT = 0.
3. Reset the correction factor: GCA = GDE
4. The scale is not loaded.
5. Query the measurement output (MSV?).
6. Enter the LDW value.
7. Load the scale with maximum capacity.
8. Query the measurement output (MSV?).
9. Enter the measured value for the maximum capacity via the command LWTcapacity>.
The input value is stored and offset with the previously measured or input LDW value.
10. Save the new characteristic curve with TDD1;.
NOTE
The characteristic curve commands LDW and LWT must be input or executed in the
following order: LDW and then LWT. The input data are only offset when both these
parameters have been entered or measured in pairs.
With partial load adjustment (measurement):
The LWT value is offset to 100% according to the input CWT value, the CWT value is then
reset to its 100% value (= 1000000).

Calibration Weight
(Weight for partial load adjustment)
 

Relevant to
verification
Yes
 

Note: ( ) Required parameters, < > optional parameters on parameter input.
DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
If you cannot apply 100 % of the input signal when adjusting the user characteristic curve,
then the CWT command also gives you the opportunity to adjust the DIS with an input signal
in the range 5 % to 120 % of the required nominal value (partial load calibration).
CWT
DIS2116 - Communication commands 43

Parameter description:
P1 is a 7 digit decimal number in the range 50000 to 1200000 (=5 % ... 120 %).
When P1 = 1000000 (= 100 %), this partial load calibration is deactivated.
P1 is a 7 digit decimal number in the range 50000 to 1200000 (=5 % ... 120 %) in not
legal-for-trade applications.
In legal-for-trade applications, the partial load calibration must be implemented with a load
of = 20% of the nominal value.
P1 is the percentage of the maximum capacity with which the next LDW / LWT adjustment
must be carried out.
Example:
The scale characteristic curve LDW/LWT of a scale is adjusted with 15 kg = 15000 d.
However, only a 10 kg balancing weight is available for the adjustment. Please proceed as
follows:
1. Set the CWT value to 666667 for the adjustment (corresponds to 66%).
2. Set the NOV value to 15000 for the adjustment.
3. Carry out an LDW/LWT–adjustment.
After the adjustment, the DIS will output the measured value 10000 digit at 10 kg and
15000 digit at 15 kg.
4. Set the increment to RSN5 and the decimal sign to DPT3. With a maximum capacity of 15
kg, this gives a partial number of 3000d = e and a display of 15.000.
NOTE
After an adjustment, the LDW and LWT values can be read out. They correspond to
parameters as if the adjustment was carried out at maximum capacity (and not at partial
load). If you need to enter the values for LDW and LWT again at a later time, you must first
enter CWT = 1000000 and then the LDW value to be read out, followed by the value read
out for LWT.

DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
This command is used to set up the scale as a one or two range scale. MRA0; deactivates
the 2-range mode. Use MRA > 0 ... NOV to specify the changeover point between range 1
and 2. When the 2-range mode is activated, then the set RSN increment applies for range 1.
The increment for range 2 is then automatically the next increment.
Examples:
RSN = 2: Range 1 with increment 2, range 2 with increment 5
RSN = 5: Range 1 with increment 5, range 2 with increment 10
When the scale is unloaded, the display changes back to the increment of range 1.

3.3 Linearization settings
The DIS has the ability of reducing the linearity deviation of the scale. The DIS works with a
3rd order polynomial. Two additional points between dead load (LDW) and maximum
capacity(LWT) must be used for this correction.
These commands must be set after the scale is adjusted (LDW, LWT, NOV).
• Measured value of the correction LIM
• Weight value for the correction LIN
Four value pairs are required to calculate the coefficients for a 3rd order polynomial:
 

These two additional points must therefore lie in the range 0 ... NOV. In addition, the
following conditions must be met:
0 < LIM1 < LIM2 < NOV
0 < LIN1 < LIN2 < NOV

Note: ( ) Required parameters, < > optional parameters on parameter input.
Function:
The LIM values are the required output values of the linearization curve.
The LIN values are the values that should be displayed for the applied weight. The LIM values are the
actual values measured for the applied weight.
Example:
Curve for unloaded scale = 0 scale loaded with maximum capacity = 10.000kg(10000)
The linearity error should be compensated for at 2.5kg and 7kg.
Use command LIN 1 to input 2500 (2.5kg) and the command LIM 1 to acquire the measured
value for the 2.5kg load.
Then use command LIN 2 to input 7000 (7kg) and the command LIM 2 to acquire the
measured value for the 7kg load.
The linearity compensation is calculated from the 4 values pairs for 0, LIN1/LIM1, LIN2/LIM2,
nominal value. Both value pairs LIN1/LIM1, LIN2/LIM2 must always be input (measured).
The value pairs for 0 and nominal value cannot be input.

Note: ( ) Required parameters, < > optional parameters on parameter input.
DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
This command selects a digital filter. This influences the filter performance of the DIS
(measurement signal bandwidth).
The limit frequency of the filter determines the settling time. The higher the filter index, the
better the filter effect, but the longer the settling time when changing the weight. The filter
setting should be chosen to be as low as possible, while still being able to ensure
non-operation (standstill) at a weight that does not change.
Mean-value calculation influences the overall settling time of the DIS. The total settling time
is also dependent on the mechanical construction of the transducer, on the dead load of the
scale and on the weight to be weighed.
Parameter description:
With ASF0, the filter is deactivated.
The measured signal filtering occurs in the load cells, please refer to the descriptions of the
load cells or measurement chain used for the filter properties.
When setting and selecting the filter, the commands HSM, ASF and FMD must be taken into

Note: ( ) Required parameters, < > optional parameters on parameter input.
DIS responds with ?CRLF, if the input or the query is incorrect.
Function:
After switching on the voltage, during a RESET or after an RES command, zero setting is
carried out after a standstill of approx. 2.5 s in the selected range. Any change to the zero on
start-up range only takes effect after the voltage cut-in or after the RES command.
If there is no standstill or if the gross value falls outside the selected limits, zero setting does
not occur. The internal zero memory is always cleared before automatic zeroing. If the gross
value at standstill falls within the selected range, the gross value is accepted into the zero
memory. Zero memory cannot be read out. The standstill condition is specified with MTD.
The unit Digit (d) is relates to the nominal value (NOV) and the increment (RSN).
