About This Reference Guide
This reference guide provides detailed specifications, diagrams and additional information required to integrate
the SX-570/580 embedded intelligent module in a product. The intended audiences are the developers and
engineers responsible for the integration of the module in another product.
Safety recautions
To prevent damage to the SX-570/580 module’s electronic circuit components, follow established
ESD practices and procedures for handling static-sensitive devices. All ESD-sensitive components must be
stored and shipped in ESD-conductive bags or bubble-wrap and labeled as such using the standardized
ESD adhesive warning label.
Ethernet electrical wiring must be at least 6 feet from bare power wiring or lightning rods and
associated wires, and at least 6 inches from other types of wire (antenna wires, doorbell wires, wires from
transformers to neon signs), steam or hot water pipes, and heating devices.
rotectors and grounding wire placed by the service provider must not be connected to, removed,
or modified by the customer.
Emissions Disclaimer
Final emission certification per FCC, CE and other agency requirements are the responsibility of the OEM using
any printed circuit assemblies or other items described in this developer’s kit in their packaged product.

Chapter 1
Introduction
The SX-570/580 embedded intelligent module provides a complete solution for integrating wireless networking
technology into virtually any OEM product that has an RS-232 or UART serial port. It has a main printed circuit
board that contains a processor, memory, flash memory, three (3) serial ports (one dedicated for use as a
console) plus a USB V2.0 host port and an S I port. The SX-580 and SX-570 are very similar. The SX-580
supports dual 2.4GHz/5.0GHz operation, while the SX-570 only operates at 2.4 GHz. Information in this
document applies to both models, except where 5GHz operation is referenced, which applies only to the SX-580.
The SX-570 measures 55.0 x 30.0 x 8.25 mm and SX-580 measures 55.0 x 30.0 x 9.25 mm.
The SX-580-6900 Evaluation Daughtercard is available to expedite the development process. This board
includes an RJ45 Ethernet connector, three 9-pin serial connectors, one USB connector, header connectors for all
major I/O, power supply, antenna, cables, and software.

Chapter 2
Installing the Evaluation Daughtercard
The SX-580-6900 Evaluation Daughtercard is designed to help you in the development of the necessary
hardware and software required to use the SX-570/580 module. It includes I/O connectors, cables, and
power supply in an easy-to-use package. The SX-570/580 Module is installed in the Evaluation
Daughtercard as shown in Figure 3.

The Evaluation Daughtercard makes it easy to connect to the SX-570/580 for test and development by
providing the following:
•Three 9-pin connectors (CN4,5,6) and one 10-pin header (CN12) for connecting the SX-570/580
serial ports
•One 20-pin header for connecting G IO's, power and ground (CN8)
•One RJ45 Ethernet connector (CN1)
•One power jack (CN7)
•2 LEDs for displaying the power and network status (LED6,7)
•5 LEDs for monitoring the G IO signals (LED1,2,3,4,5)
•One Test Button for printing configuration data and resetting the unit to factory defaults (SW2)
•Three 12-pin header (J 20,21,23) for selecting G IOs and one 12-pin header (J 22) for
selecting S Is.
The locations of the major Evaluation Daughtercard connectors and headers are shown in the diagram
below.

Connecting the Evaluation Daughtercard to C
To connect the SX-580-6900 Evaluation Daughtercard to your C:
1. Connect one serial null-modem cable from the Serial ort (CN6) DB-9 connector on the Evaluation
Daughtercard to a serial port on a personal computer or laptop (the computer’s serial port must be set
to 115.2Kbps, no parity, no flow control, and 8-bit character size). The C or laptop acts as a console
port for command line configuration and monitoring. (CN6 is the Linux console which provides access
to the on board Linux system, while CN5 is connected to the configuration application, and is
connected to the console configuration task. Linux functions are not available from CN5.)
2. If you want to use an Ethernet LAN connection for the initial configuration of the SX-570/580, plug a category
5 Ethernet cable into the RJ-45 jack. The Ethernet interface has Auto-MDI/MDIX that automatically detects
and configures itself for either a straight-thru or crossover Ethernet cable.

Monitoring Module Status
You can monitor the module status using the Status LED (Orange) on the Evaluation Daughtercard.
Table 2 defines the default functions of the LED status indicators.
Table 2 Status Monitors

SLED On The network connection is active (wired/wireless).
Off The network connection is not active.
Blinking Firmware update is in progress (Important: Do not
power off the module during the update process)
OEM Interface
The OEM interface is a 50-pin header (CN9) that is used to connect the SX-570/580 module to the SX-580-
6900 Evaluation Daughtercard. It will also serve as the primary means of communications between the SX-
570/580 and your OEM device (refer to Chapter 5 for information on using this header to connect with your
device).
Table 3 shows the OEM interface pinout for the Evaluation Daughtercard. lease note that the OEM
interface signals are not directly accessible from the OEM header when the Evaluation Daughtercard is
used. Rather, these signals are available through convenient connectors on the Evaluation
Daughtercard, such as the CN8, CN12, CN13, CN14, CN15 and the 9-pin serial connectors. These
connectors are described later in this chapter.
All input and output signals, except the differential signals, are 0 to 3.3 V logic signals.

Serial orts
Standard serial RS-232 signals are available on the DB-9 male connectors CN4, CN5 and CN6 for Serial
orts 1, 2 and 3 (Serial ort 3 is the Linux console which provides access to the on board Linux system,
while Serial ort 2 is connected to the configuration application, and is connected to the console
configuration task. Linux functions are not available from Serial ort 2.) Serial ort 1 includes the RTS
and CTS modem signals for hardware flow control, and can also support DCD, DTR, and DSR by setting
the appropriate jumpers on the J 20 and J 23 header (see the Using the GPIO Special Functions
section later in this chapter). Serial ort 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.
Table 4 DB-9 inouts for RS-232 Mode
DB-9 RS-232 Signal Type
1 DCD Input
Enabled via J 23 header (Serial ort 1 only)
2 RXD Input
3 TXD Output

6 DSR Input

7 RTS Output (Supported on Serial ort 1 only)
8 CTS Input (Supported on Serial ort 1 only)
9 NC
Serial ort 1 can also be accessed using logic signals via a 10-pin header located at CN12. If you want
to use this header, you must place a jumper on 3.3V header (CN12) at J 24 to disable the RS-232
transceiver. The pinouts are as follows:

1 DCD Input
Enabled via J 24 header
2 DSR Input
Enabled via J 24 header
3 RXD Input 4 RTS Output
5 TXD Output 6 CTS Input
7 DTR Output

8 3.3V
9 GND 10 No

All signals are 0 to 3.3 V logic signals.
Note that Serial ort 3 is dedicated for use as Linux console commands. Serial port 3 is always set for
operation at 115.2Kbps, 8 bit character size, no parity, and no flow control.
Serial ort 2 is set by default for console operation at 115.2Kbps, 8-bit characters, no parity, and no flow control.
This port can be set as a second I/O port using the SET ORT S2 CONSOLE DISABLE console command.
RS-232 Cable
The supplied DB-9 female-to-female null modem cable is wired as shown below. The pinouts are
compatible with a standard C 9-pin serial connector, so this cable can be used to directly connect a C
to Serial ort 3 for use as a console terminal to configure the SX-570/580. It can also be used to connect
many types of OEM serial devices to Serial ort 1 or Serial ort 2, provided that these devices use C-
compatible 9-pin connectors.
