modes are described below.
Power Input
Power to the SX-550 Module and the SX-550-6900 Evaluation Daughtercard is supplied through the
power jack, located at J4, at +5VDC ±10%. Use the included power supply or an equivalent +5VDC
power supply with a minimum of 1 amp capacity.
power jack, located at J4, at +5VDC ±10%. Use the included power supply or an equivalent +5VDC
power supply with a minimum of 1 amp capacity.
Power of +3.3VDC ±5% is input to the SX-550 Module via the OEM header, J5.
Power Management
Power for the SX-550 Module is less than 3 watts in normal power mode and peak consumption is less
that 3.3 watts. In low power mode average power is 1.2 watts.
that 3.3 watts. In low power mode average power is 1.2 watts.
Serial Ports
The two serial ports can be accessed with RS-232 signals, via the DB-9 connectors, or logic signals, via
the 10-pin headers. Note that serial port 2 is dedicated for use as a console port for configuring the SX-
550. Serial Port 2 is always set for operation at 115.2Kbps, 8 bit character size, no parity, and no flow
control.

The two logical serial port headers are located at JP2 and JP6. The serial ports provide four dedicated
signals and three optional signals. The optional signals are configured using jumpers. Table 5 details the

All signals are 0 to 3.3 V logic signals.
To use header JP2, disable the RS-232 transceiver, U3, by placing a jumper on both JP8 pins.
To use header JP6, disable the RS-232 transceiver, U6, by placing a jumper on both JP9 pins.
