CHAPTER 6
• CLICK 510
If you would like for the device only to receive data, select the Switch option and then don’t
push the button while receiving data.
Test Pattern submenu 2 allows you to select which data packet will be sent to the Click 510
or computer. The submenu 2 selections are displayed on the device by the red LEDs (see
Figure 7.3). Data packets come in two forms; LED commands and ASCII text strings. When
you connect two Click 510 devices via your communication channel, the LED commands
will be received as long as both devices are in Test Pattern operating mode.
˽
LED flash –
Sends a message for all the submenu (red and yellow) LEDs to flash at
once. If it is received by a Click 510 the LEDs will flash; if it is received by the computer,
the message will appear as “f” in HyperTerminal.
˽
LED sequence –
Sends a message for each submenu LED to flash in sequence, start-
ing with the first yellow LED. If it is received by a Click 510 the LEDs will light up in
sequence; if it is received by the computer, the message will appear as the digits 1–8 in
HyperTerminal.
˽
ASCII sequence –
Sends an ASCII sequence—a lowercase alphabet—across the com-
munication channel. This pattern should be sent by the Click 510 to a computer; if it is
received by a Click 510, it will only register in the yellow (receive) system LED.
˽
ASCII text –
Sends an ASCII text message—“The Click Tester has been powered on for
XX hr XX min XX sec!”—across the communication channel. This pattern should be
sent by the Click 510 to a computer; if it is received by a Click 510, it will only register
in the yellow (receive) system LED.
Figure 6.5 – LED Commands and ASCII Text Strings in HyperTerminal
The four test patterns, as well as several other types of data packets, can also be sent from
your computer to a Click 510 via HyperTerminal. The following commands can be sent
(you can also see this menu by typing “m” in HyperTerminal):
˽ 1 . . . 8 – Lights up the corresponding LED on the Click 510. For example, typing a 5
causes the fifth LED to illuminate. The yellow LEDs are numbers 1–4 and the red LEDs
are numbers 5–8.
˽ f – Causes all the submenu LEDs to flash at once (this is the same as LED flash on the
510 menu).
