LED Test
The LED test checks the functioning of the display by lighting all the LEDs in the matrix. It also
tests the buzzer by changing the frequency to produce a variation in the tone of the sound.
There is no message displayed concerning the outcome of this test, which must therefore be
checked visually.
6.2.1.3.
Serial Ports Test
The serial ports test checks the communications on the following interface ports:
• CSafe COM test;
• Low Kit COM test;
• TGS COM test.
Using the + and – effort level keys, select the desired test item and confirm by pressing ENTER.
The test can have two outcomes:
• "Test Successful, press Enter to continue": This means that the test was completed
successfully, i.e. that the communications on the selected serial port are functioning correctly.
• "COMx error, press Enter to continue": This means that the outcome of the test was negative:
the message will specify COM1 in the case of the CSafe COM test, COM2 in the case of
communications with the low kit, or COM3 in the case of the TGS COM test.
The "TGS COM test" done on machine not provided with the key reader gives a fail outcome.
The same if the "CSafe COM test" is done on a machine which CSafe port is not plugged with
the monitor plug described at paragraph: 4.4. "Monitor plug for CSafe port".

The manual keyboard test checks the functioning of all the keys on the keyboard. After accessing

not working properly.
