Safe Rail System Data Acquisition Software

Fig. C. 5 - Com settings window

For example, selecting External device type RS-232 GPS :



Select 1 in the

Com

menu (or set the number of the COM port

number the GPS is connected to) and the other parameters according

to the GPS characteristics;



Use the

Refresh rate

field in Fig. C. 3 to select the number of

sweeps interval the GPS data will be acquired with; for example, if

you have set the

Acquisition Step

to 2.4cm and the

Refresh rate

field to 20, the system will acquire GPS data every 48cm (2.4cm

*20=48cm); if the

Refresh rate

= 1, the SRS_PLUS system will

uptake all the information produced by the GPS according to the

time parameters set on GPS equipment.

Step 5

Accept the parameters set in the

COM settings

field by clicking the

button, as shown Fig. C. 5.

Step 6

Correct functioning of the GPS and its communication with the

SRS_PLUS system is indicated by the GPS

spy light in the acquisition

window; when the light is green, the GPS is correctly connected and

functioning; when the GPS is red, either the connection between the GPS

and SRS_PLUS systems has not been correctly made or the GPS is

switched off (see picture Fig. C. 6).
