40. Select the transfer rate in bits/s.
41. Select the number of bytes per character:
You can select 7 or 8 bits.
If the MODBUS RTU protocol is used, it cannot be modified, the value is set to 8
bits.
42. Sets the parity bit for error control.
The possible modes are None, Even Parity, and Odd Parity.
43. Select the number of stop bits, 1 or 2 bits for information synchronization.
44. Sets the value of the position of the first character to be displayed.
This option is intended to prevent the display of headers or labels that other devices may
send along with the information. For example, a scale could send "Weight (Kg): 203.5".
If the value 1 is applied, all the characters up to the first number will be ignored,
very useful if the label is variable (NET WEIGHT (Kg), AVERAGE WEIGHT (Kg),
etc...).
Values greater than 1 allow focusing on a part of the numerical data, useful in
processes where the numerical value does not vary much. In this way, for
example, the thousands could be ignored in a process where only the units or
tens change.
Example: The information "PESO 203.5" is sent. Depending on the value of this
element (13), the following situations would occur:
G. 0. As many characters as the display has, are shown. "PESO 203.5" is
H. 1. Everything up to the first numeric character is skipped. "203.5" is
I.
45. Allows to invert the order of the value displayed:
Example: The value "123456" is sent to the display, depending on the chosen
parameter two situations can be displayed:
E. NORMAL. Shows "123456".
F. INVERTED. Shows "654321".
46. This parameter complements parameter 13, but for the final part of the message. That is,
you choose how many values to display counting from MSG.OFFSET.
The value of this parameter has different effects depending on the previous
element (14).
E. NORMAL. Shows only the beginning of the message up to the
F. INVERTED. Skips the start of the message (pre-reversal) to the

7. The first 7 characters are skipped. "3.5" is displayed.
designated position.
Example: With MSG.CURSOR = 3. If "123456" is sent, "123" is
displayed.
Example 2: With MSG.CURSOR = 2. If "123456" is send, "12" is
displayed.
designated position.
Example 1: With MSG.CURSOR = 3. If "123456" is send, "654" is
displayed.
Example 2: With MSG.CURSOR = 2. If "123456" is send, "6543" is
displayed.
