12 Switch-0 Function switch CMOS In Used for the “Connect on external
signal” function, see the Serial Port
Adapter AT command Specification
for more information on the Func-
tion switch.
See section A.2.3.4 for design ex-
amples.
13 GREEN/
Switch-1
Green LED output and
Restore switch
CMOS In/Out This signal is multiplexed:
GREEN:
Logic Green LED Signal (see Chapter
3, Table 8). Not valid until 500ms
after startup.
Switch-1:
If the level on this pin is pulled-
down with 1kΩ** the units goes
back to default serial settings.
The “Restore Default” input is only
active during the first 500ms after
startup.
See the Serial Port Adapter AT
command Specification for more
information on the Restore switch.
See section A.2.3.3 for design ex-
amples.
14 BLUE Blue LED output CMOS Out Logic Blue LED Signal (see Chapter
3, Table 8).
Note:
Signal will flicker at data transmis-
sion.
See section A.2.3.1 for design ex-
amples.
15 UART-CTS* Clear To Send CMOS In Hardware flow control.
16 UART-TxD* Transmit Data CMOS Out
17 UART-RTS* Request To Send CMOS Out Hardware flow control.
18 UART-RxD* Receive Data CMOS In
19 UART-DTR* Data Terminal Ready CMOS Out
20 UART-DSR* Data Set Ready CMOS In
* All signals are logic level UART signals (typically 0 - 3VDC)
** Use 1kΩ as pull-down which is different to previous product generations from connectBlue
