3.2 - Transmission check

The trial consists in verifying whether the command (of elevation or of rotation) correctly reaches

the treadmill. It requires the use of software installed on a personal computer in order to send the

command to the treadmill.

If the transmission of the command does not work, the software should show an error message.

Consequently, if the error message shows on the PC, it means that the transmission check is not

OK. Should this not occur, the transmission check should be considered OK.

Note: Unfortunately not all software on all PC’s have the possibility of determining whether the

command reached the treadmill in the correct manner, and therefore in these cases, one should

consider the check not OK, even in the absence of error messages.

3.3 - Connection check

With this check one must verify whether the connectors of the RS232 cable are properly inserted in

the ports of the PC and of the treadmill. It requires the manual verification of the positioning of the

connectors and possible reinsertion of them.

After this verification, one must send a new command (of elevation or of rotation) to the treadmill

and verify if the treadmill responds accordingly or not. If the treadmill correctly executes the

command it means that the connection check is OK, otherwise not OK.

3.4 - RS232 cable check

This check consists of the verification that the connection cable RS232 between the PC and the

treadmill is intact. It requires a visual trial, checking that the cable has not undergone damage and

that it is immune from cuts, tears, or crushing.

If the cable appears in a good state the check of the cable RS232 is OK, otherwise not OK.

3.5 - Substitution of RS232 cable

Essential tools:

• Screwdriver

Essential replacement parts:

• RS232 serial cable

This very simple procedure requires removal of the RS232 cable disconnecting the cable from the

ports and then substituting it with a new cable.
