* All signals are logic level UART signals (typically 0 / 3.0VDC).
** Use max 4.7kOhm as pull-down which is different to previous product generations from connectBlue.
*** Alternative signal pin recommended to use in new designs (both signal pins should be connected).
**** Available on request. Contact
The cB-0939 module has an step down DC/DC voltage regulator, which means that the current decrease if the voltage supply level is
increased.

Used for the "Connect on external signal" function, see the
Serial Port Adapter AT command Specification for more
information on the Function switch. Active low.
A secondary function is that the module will restore all factory
settings if both the Switch-1 and Switch-0 signals are low
during start up.
See the Serial Port Adapter AT command Specification for
more information on the Restoring Default Configuration
functionality.
See section
This signal is multiplexed:
GREEN:Logic Green LED Signal (see the
section). Not valid until 500ms after startup. Active low.
Switch-1: If the level on this pin is pulled-down** the unit goes
back to default serial settings. The Switch-1 input is only
active during the first 700ms after startup. The module will
restore all factory settings if both the Switch-1 and Switch-0
signals are low during start up.
See the Serial Port Adapter AT command Specification for
more information on the Restoring Default Configuration
functionality.
