2.0 Installation
This section provides an overview of LaserLT-60 and LaserLT-100 installation.
Install the instrument on a stable, vibration free, flat surface. Disconnect from power source to completely power off the
instrument. The back mounting bracket is for vertical mounting. An optional side mount for horizontal surfaces is available for
the LaserLT-100.
Remove protective film from the overlay as it may become difficult to remove if exposed to heat or sunlight.
2.1 Grounding the System
For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in proximity of the
instrument on which to connect the ground of the instrument, an interface cable and shields. Connect the ground point of the
remote display directly to the ground bar of the electric panel or to a grounding rod.

2.3 Power Supply
The instrument is supplied with an AC power cord, connected to an internal AC/DC power adapter. To power the instrument
with 12 VDC or 24 VDC, connect the power supply cable directly to the terminal strip on the CPU board, see J1 in Figure 2-1.
This input is for static DC, not for an automotive source.
The maximum power of the outputs 48 VAC 0.15A max (or 60 VDC 0.15 A max), the maximum voltage applicable to the inputs
is between 12 VDC and 24 VDC with current from minimum 5 mA to maximum 20 mA.

3.3.1 String Example
The weight value of the first character position is defined within the parameter of weight position, or Wei.pos, in the string
transmitted by indicator. A possible polarity sign is also part of the weight value. The unit can parse a string up to 39 characters.
For example, if the received string is bpwwwwwwwLGS+CR+LF:
Received String
String Position
b p w w w w w w w L G S CR LF
00 01 02 03 04 05 06 07 08 09 10 11 12 13

3.3.2 Advanced Parsing Parameters
Advanced Parsing Parameters utilize logical operators and bit masking to set the individual bits of the string to read the sign,
stability, zero and over/under load and units.
Figure 3-6. Advanced Configuration Parameters
Parameter Description
W.nEt Weight Net – Bit and character that indicates if the weight is net
nEG.SiG Negative Sign – Bit and character that indicates if the weight is positive or negative
StAbiL Stability – Bit and character that indicates if the weight is stable
W.ZEro Weight Zero – If the value is not set (MASK = 0) the scale is considered to be in the zero range when the weight is equal to 0
W.UnDeR.L Weight Under Load – Bit and character that indicates if the weight is under load
oUEr.L Over Load – Bit and character that indicates if the weight is over load
Unit 1 Unit 1 – Lights W1; If 076 lights unit 1, the unit of measure is L, or pounds;
Unit of measurement stickers are provided to replace W1 function LED labels
Unit 2 Unit 2 – Lights W2; If 075 lights unit 2, the unit of measure is K, or kilograms;
Unit of measurement stickers are provided to replace W2 function LED labels
Table 3-4. Advanced Parsing Parameter Settings
Each of the Advanced parameters are defined by setting the following parameters:
Parameter Description
mask Mask – Byte where will extract the data, relative to step indicated in AdU.CEd (from 0–255); Character is logical Adv.Ced with this mask,
the result is compared with Value; Parameter is not managed if the value is set to 0
n.byte Index Byte – Indicates the character where the data will be extracted; Character index in the string
value Value – Character value that defines what was selected in AdU.CEd step; If the character of the string is a letter it is necessary to insert the
relative ASCII code value Und.Our if the tr.L0 is set and the tr.HI parameters will be ignored
Table 3-5. Advanced Parsing Parameter Settings
Example: If the string sent by the scale indicator has the form: WWWWWWF<CR><LF>
Where WWWWWW is the weight, F some flags.
Wei.pos will be 0. Wei.Len 6.
If check bit 2 of flag character F is desired and this bit is about negative weight, then set in Adv.ced / Neg.sig:
• Mask = 4 (if check bit 2 is desired, binary mask is 00000100, decimal = 4)
• N.Byte = 6
• Value = 4
When character 6 of the string AND (logical AND) Mask = 4 weight is considered negative.

Page 13
Check Multiple Bits
Sum the mask decimals of all bits to be checked to check multiple bits.
Example: Check bits 7 (decimal 64) and 6 (decimal 128) the mask will be 192 (binary 11000000).
Sum all mask decimals to check a whole character.
Example: If the stability condition is a character ‘S’ in a certain position, the mask will be 255 (11111111 binary) and
value will be 83 (ASCII code of character S). When character and 255 (character remains unchanged) is equal to
ASCII of S (83) the weight is considered stable.

3.4 Semi Auto Learn Using rEPE.in
rEPE.in is a semi-automatic mode to establish the start and end positions of the weight value. rEPE.in has no parameters
and does not read annunciators for units, mode, or status. This parameter is in the PCMode.
The polarity sign is to be included as part of the start position. The total weight length can be more than six characters. If a
negative value is present, the negative sign will be placed in the character to the left of the displayed value, as long as the value
is not more than five digits.
