second during normal operation while bus signal
and power is fully connected. It will also generate a

a short circuit condition.

Pin 1 and pin 3 are jumped together in default to allow single
toggle switch operation, which both power and bus signals are
turned on together. User may connect an external toggle switch
to pin 5 or an external TTL high signal to pin 8 to control the
board.
To control the bus signals separately from the bus power, remove
the jumper at pin 1 and pin 3 and connect external TTL control at
pin 3. Power should be connected first, then the bus signals.
The on-board toggle switch should be at down (off) position, if
external TTL control is used.
