Power Arrangement
The DS1206N-RS and "-TM" devices have "12V"-to-3.3V switching regulator
onboard. Conventionally, the power is supplied through the power jack. The Power
Jack of the DS1206N accepts "small" power connectors with 3.5mm diameter. Use
, or
power adaptor supplied by Tibbo or similar
adaptor with 12V nominal output voltage. Adaptor current rating should be at least
500mA. On the power jack, the ground is "on the outside", as shown on the figure
below.
Alternatively, the DS1206N-RS can be powered through pin 9 of the DB9M (RS232)
connector, while the DS1206N-TM can be powered through pin 2 of the TTL
interface connector. Two internal diodes combine power jack and pin 9 (pin 2)
inputs into a single line, which goes to the internal regulator of the DS1206N.
On the DS1206N-RS, pin 9 of the DB9M connector can also be used to provide "12V"
power to an attached serial device. "12V" actually means "input power on the power
jack", which is not necessarily stabilized. The power line of the jack passes through
a software-controlled switch and is then connected to pin 9 through a Schottky
