The SRBC-16F2BL modules feature an enable

pin with negative logic. If not using the enable

pin, leave the pin open (the module will be on).

During logic_high, the module is turned off,

during logic_low, the module is turned on. It inner

circuit impedance is showed as figure.

The SRBC-16F2B0 modules feature an enable

pin with Positive logic. If not using the enable pin,

leave the pin open (the module will be on).

During logic_high, the module is turned on,

during logic_low, the module is turned off. It inner

circuit impedance is showed as figure.
