Power Management

The SX-560 power consumption is typically 280mA for wireless-to-serial usage, with a peak consumption is 400mA @ 3.3V. In powersave mode (refer to Chapter 4 for more information) with the SX-560 connected wirelessly to an access point, the consumption is 60mA while idling and an average of about 73mA including wakenings to answer the beacon poll.

The above numbers assume that the only active connections are the 802.11 wireless interface and the serial interface (for example, there are no connections to the GPIOs). Power consumption specifications are subject to change; contact Silex for more information.

Serial Ports

Standard serial RS-232 signals are available on the DB-9 male connectors J3, J4 and J5 for Serial Ports 1, 2 and 3 (Serial Port 3 is dedicated as a console port, while Serial Port 2 can be set as either a console port or an I/O port), as shown in Figure 4. Serial Ports 1 and 2 include the RTS and CTS modem signals for hardware flow control, and Serial Port 1 can also support DCD, DTR, and DSR by setting the appropriate jumpers on the JP9 header (see the Using the GPIO Special Functions section later in this chapter). Serial Port 3 does not support any modem signals, and is fixed for operation at 115.2Kbps, no parity, no flow control, and 8-bit character size.

The DB-9 connectors use industry-standard PC-compatible pinouts as shown below:
