Electrical Characteristics

The power requirements, port pinouts, GPIO characteristics, cable connections and wireless operational modes are described below.

Power Input

Power to the SX-550 WLAN Module and Evaluation Daughtercard is supplied through the power jack, located at J4, at +5VDC ±10%. Use a +5VDC power supply with a minimum of 1 amp capacity.

Power of +3.3VDC ±5% is input to the SX-550 WLAN Module via the OEM header, J5.

Power Management

Power for the SX-550 WLAN 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.

Serial Peripheral Interface

The four SPI signals are accessible using the 20-pin header JP7. The Data Out, Data In and Clock signals are routed to both the JP7 header and an on-board temperature sensor. The SPI Chip Select signal is selectable to either the JP7 header or to the temperature sensor using the 3-pin header JP1.

Additional OEM Interface Signals

The output LED signals ORLED-, GRLED- and YELED- represent the state of the LEDs on the module. Logic 0 indicates the LED is on, and Logic 1 indicates the LED is off. Buffers are recommended if LEDs are to be driven on the end-user side.

The SWITCH signal is connected to a momentary pushbutton switch on the evaluation daughtercard and is in the normally open position. Depressing the switch causes a short to ground. A 4.7 K-ohm pull-up resistor to +3.3 VDC is connected. The module’s processor monitors this signal. The end-user can drive or use open-collector to this signal to either logic level or can monitor this signal as an input.

Using AT Modem Commands

The Evaluation Daughtercard contains a wireless serial device firmware with optional data filter for configuring using AT style modem commands. This feature allows devices with an existing AT command interface to configure the unit, if the AT commands can be properly modified. You must be familiar with the general operation of AT commands. Note that AT command processing is not enabled by default. Use the command SET PORT S1 FILTER AT to enable this feature.

All commands begin with AT and are terminated by a new line unless noted below. While standard AT commands are defined to be 40 characters or less (not including the AT), the server accepts commands of up to 80 characters.

Standard AT Commands Supported

The following standard AT commands are interpreted by the device server. The data channel must be in the command mode for commands to be recognized. The data channel will be in command mode upon power up or reset.

There are two operating modes for the unit when the AT command option is enabled. In command mode, data received from the serial port is passed to the AT command processor, and responses are returned to the serial port. No data is sent to any network application, and any data received from the network is ignored. In data mode, data from the serial port passes to the network application, and vice versa. This is equivalent to the normal serial port operating mode without the AT command option.

Table 16 describes the AT Commands. Table 17 details the Extended AT Commands that allow the configuration of the network server operating parameters.

Page 30 silex Accessing Configuration Parameters

Part Number 40183-101

Any AT command received, except the listed commands, are acknowledged with OK status. This allows existing modem applications to transmit commands without causing an error. These include AT<X>n, but not currently AT&<X>n, AT%<X>n, AT\<X>n, where <X> is a letter.

Table 16 AT Commands

Parameter Command Description

Enter Command mode <delay>+++<delay> If the string +++ is seen in data mode, with no

characters sent for 1 second before or after, then command mode is entered.

Initiate Connection Command

ATD <destination> Standard modem dialing command, redefined to

initiate an internet connection to a remote computer.

Indicates the IP address of the target, and optionally the TCP port number to use for connection. The T or P option (ATDT or ATDP) can be present and has no effect.

If present, the IP address must be exactly 12 decimal digits with 3 for each byte of the address.

If no IP address is given, then the ecable destination address defined for the port is used.

If the destination TCP port is defined, it is separated from the IP address by a '#' character, and is 1 to 5 decimal digits.

If TCP port is defined, the ecable destination port defined for the serial port is used. If the destination port is 0, the standard Telnet port (23) is used.

If the destination string ends with a semicolon, the server remains in the command mode, not the data mode, once a connection is made.

In command mode data is not passed from the remote computer, so data could be lost if the unit stays in command mode.

If the connection cannot be attempted, NO CARRIER status is returned. If the connection attempt fails, NO ANSWER status is returned.

If the connection succeeds, CONNECT status is returned.

Echo control

ATEn If n=0, commands are not echoed.

If n=1, subsequent commands will be echoed.

The default, upon unit reset, is for no echo (ATE0).

Disconnect ATHn If n=0, any connection to a remote host is dropped.

Other value of n is ignored.

Return to data mode ATOn Exits command mode and places the serial port in

the data mode.

All subsequent data is sent to the network application, if connected, until an enter command mode sequence is received. Any value of n is ignored, if present.

Parameter Command Description

Console pass through

AT#C<string> Passes the string to the server configuration console.

The string can be any valid console command. Refer to your server documentation for console commands available on your unit.

Since this command does not follow the normal AT command format of <command><number>, it must be the last command on the line unless the next command is a '#' command. All characters up to the end of line or a '# will be considered part of the console command.

If console quiet mode is not is enabled, then the response will be the standard console task response.

Example:

AT#Cset nw ssid silex#Csave

Configure Simple Network Management Protocol

The SX-550 module contains a Simple Network Management Protocol (SNMP) agent that collects and stores management information for network managers using standard SNMP commands. The management information is referenced as a hierarchically organized database called a Management Information Base (MIB).

To prevent naming conflicts, all of the manageable features of all products from all vendors are arranged in a single tree structure. Each vendor of SNMP equipment has an exclusive section of the MIB Tree .

Each branch of the MIB Tree has a number and name. The path from the top of the tree down to the point of interest forms the name of that point. A name created in this way is known as an Object ID or OID.

Table 23 describes the messages used to communicate between the network manager and the SNMP agent, as defined in RFC 1157. Each SNMP message must contain a Community Name, which is used like a password. The default Community name for the SX-550 module is PUBLIC.

Table 23 SNMP Commands

Command Description

GET Retrieves management information for a specific managed object contained in the

agent.

The GET message must contain the OID for the specified object. The response is a GET-RESPONSE message containing either the current value of the requested object, or an indication as to why the request failed.

GET NEXT Retrieves management information from a non-specific managed object.

The GET NEXT contains either a complete OID or a fragment of an OID. The response is a GET-RESPONSE message containing either the OID and data of the item immediately right of the specified OID in the tree or an indication as to why the request failed.

GET RESPONSE

This is the information sent back from the unit in response to the GET, GET NEXT command.

SET Requests a change to the value of a specified object.

The response is a GET-RESPONSE message with either an indication that the requested change had been made or with an indication as to why the request failed.

TRAP Sends a one-way notification from the agent to the manager that a significant event

has occurred. This is the only message initiated by the SNMP agent.

To set the SNMP Traps:

1. Using ExtendView, web browser interface or internal command console, click SNMP Traps tab. The SNMP Traps window displays.
