5.12.1 Data Fields
Data fields show the data from the sign’s internal RTD buffer. This field will show up
as a series of X’s in the Message Editor.
If a data field is chosen, the next step is to identify the proper offset and length.
Offset: The offset is the location in the sign’s RTD buffer where the information to be
displayed will begin. For information on this number, refer to the RTD “item number”
definition of the RTD source. The default offset is zero-based.

The offset for RTD input in the Venus 1500 software can be customized to meet
individual customer needs. From the Editor Defaults dialog box (refer to Section
5.17), select either Zero-based or One-based for the desired offset.
The user can determine the current setting by observing the text located to the right of
the offset parameter in the RTD configuration dialog boxes as shown below:
The Venus 4600/6500 and Venus 7000 controllers use an “item number” for RTD
offset. Unlike the Venus 1500, the item number is one-based. If you are operating a
system using both the Venus 1500 and another Venus controller, be aware of this
difference.
Length: The length is the number of characters to show from the sign’s RTD buffer,
starting from the offset.
5.12.2 Horn Field
Horn fields control the horn of the sign, if
one is installed. It is designed for use with
sporting applications, receiving RTD
feeds from some external Daktronics
sports controllers. This field appears as
H’s in the Message Editor, but when the
message runs, nothing is visually
displayed. Due to this action, it is
recommended to place horn fields at the
end of a line in a message.
Horn Fields are specified by the port and offset.
