TDC Ultra User’s Manual

A-8

Data Output Format

The following information is not normally needed to use the TDC Ultra.

It is provided for those who are interested in some of the technical aspects

of the TDC Ultra. It is also provided for those customers who do not plan

to use the analysis software, or who are interested in interfacing the TDC

Ultra to their own computer hardware and/or software systems.

The data that is sent out of the TDC Ultra is in standard ASCII (text) format.

Any communications program, such as Windows Hyperterminal, can be used

to capture the data. It is also easy to write software that can read the raw

data, if you are familiar with a programming language. (Doing something

with the data is another matter.)

Each interval of data is sent separately. The format of the data for each of

the TDC Ultra’s studies is as follows:

Standard Turning Movements, Roundabout:

varies* leader characters (20)

001 count number

001 interval number
