7.6 Terminal Displays

In addition to the ‘static’ displays described so far, the detector may be continuously

updating some outputs.

For example, entering ‘SPD’ displays the current speed of the vehicle being detected:

SPD:45

SPD:40

Second vehicle

SPD:33

Third vehicle

Although not clear from the above diagram, the new display will appear on the same

line as the original, thus overwriting the old display, and not on the following line as the

diagram may imply.

Note: Functions that have data changes which occur more often than once a

second may not be accurately reflected on the terminal display. For example, if

‘DOS’ is used to display detector activations, then very short activations

(<200mS) may not appear on the terminal display.

7.6.1 SieCom Implementation

The user may find they are using the Siemens SieCom interface connection with either

a cable connection or a wireless link. In both cases, if a continuous updated is required

the command ‘POLL’1 must precede the updateable command.

For example; ‘POLL DOS’ will provide a continuous updated display of the detector

output condition.

This is a function of the Siecom terminal interface not the detector unit. If terminal connection is made

via a normal terminal unit (e.g. hyperterminal), then the ‘POLL’ command will not be required.
