Pushbutton Reset
Connector J18 includes an input for a pushbutton reset switch. Shorting J18 pin 40 to ground
causes the Bengal to reboot.
The input can be connected to ground using the normally open contacts of a pushbutton switch or
a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. The
input must be driven to a voltage between 0 V and 500 mV to be recognized by the Bengal. Do
not add an external pull-up resistor to this signal.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
A reset button is provided on the VL-CBR-5015 paddleboard (S2). Header J2 on the paddleboard
also provides a reset signal on pin 11 and ground on pin 14.
Note:
Holding the reset button in when powering on the board prevents booting and requires a re-
power. Make sure the reset button is not being asserted low when powering on the board.
Speaker
Connector J18 includes a speaker output signal at pin 39. The VL-CBR-5015 paddleboard
provides a Piezo-electric speaker (as shown in Figure 8).
