! " # $ % figure 1.0.1 an example 802.11b/g/n network with WSN802G sensor nodes is shown in figure 1.0.1. a sensor net- work application running on a server or pc communicates with one or more WSN802G sensor nodes through a commercial 802.11b/g/n router. WSN802G sensor nodes can be used with 802.11b/g/n routers that are also serving other applications.

WSN802G modules can receive configura- tion commands through either their serial port or over-the-air in udp packets carrying snmp commands. 1.1 features WSN802G modules provide a unique set of features for wireless sensor network applications: ? compatibility with commercial and industrial 802.11b/g/n routers ? low power consumption for long life battery operation including sleep mode ? full -40 to +85 o c industrial temperature range operation ? analog and digital i/o, plus two serial and one spi port ? separate data and diagnostic ports ? system/application set up using just two management information blocks (mibs) ? full 14 channel 802.11b/g coverage for world wide operation ? fcc, canadian ic and european etsi certifications ? four module configurations: WSN802Gc - solder reflow mounting with rf connector for external antenna connection WSN802Gca - solder reflow mounting with integral chip antenna WSN802Gp - plug in connector mounting with rf connector for external antenna connection WSN802Gpa - plug in connector mounting with integral chip antenna ? automatic or manual i/o data reporting 1.2 applications WSN802G sensor networks are well suited to applications where ieee 802.11b/g/n router compatibility, industrial temperature range operation and long battery life are important. many applications match these criteria, including: ? energy monitoring and management ? physical asset management ? cold chain data logging and food safety ? security and access control systems ? environmental monitoring ? many more

figure 2.5.1 figure 2.5.1 shows the signals a WSN802G uses in spi master mode. the autoreport function triggers the WSN802G module to clock out a configurable command string, spi_mastercmdstr , to collect data from a slave peripheral. the collected data is then transmitted as a data message. alternatively, a host connected to the base can transmit an spi command as a data message to the remote. the WSN802G will clock the command into its slave peripheral and transmit back the slave ? s response, as show in fig- ure 2.5.2. in either case, data strings are limited to 256 bytes. $ / ( , ) 4 2 ( , (

( ' ' ) figure 2.5.2 2.6 analog i/o the WSN802G includes two 10-bit adc inputs, adc0 (pin 18) and adc1 (pin 19). pin 25 provides a full- scale reference voltage to support ratiometric adc measurements. adc measurements are triggered and added to the automatic i/o report when a logic high signal is first applied to the wake_ in pin or the autoreport timer fires, as discussed in section 2.2. an adc reading is also made on the internal buss voltage of the WSN802G and included in the automatic i/o report. these readings can also be retrieved anytime the WSN802G is in active mode using the io_report application protocol command as dis- cussed in section 4.1. the WSN802G also includes a 16-bit pulse width modulated output, pwm0 (pin 9). the pwm output is low-pass filtered to provide an analog output voltage with ripple suppressed to 7 bits. external low-pass filtering can be added to further suppress ripple. the full-scale pwm output is referenced to the regulated

WSN802Gp modules are mounted by plugging their pins into a set of mating connectors on the host circuit board. refer to section 10.3 and/or the WSN802G data sheet for mounting details. WSN802G enclosures must be made of plastics or other materials with low rf attenuation to avoid com- promising antenna performance where antennas are internal to the enclosure. metal enclosures are not suitable for use with internal antennas as they will block antenna radiation and reception. outdoor enclo- sures must be water tight, such as a nema 4x enclosure.

WSN802G modules support two snmp oid parameter sets, as discussed in section 7.2 below. the first set of oids is very similar to the oids in the WSN802G modules prior to revision f. there are a few oids that did change - these are detailed in the document 11 mbps firmware changes which can be found on the cd in the developer ? s kit or on the rfm website in the module tech support section. the second set of oids, distinguished by a different left-hand string, includes most but not all of the oids in the first set. traps, time-related parameters, and firmware upgrade related items are only found in the first set of oids. where there is duplication, it does not matter which oid is used as they operate identi- cally. the last two, non-zero, oid values of the second set of oids are the same as the bank and loca- tion values used in the serial port configuration commands. for example, to read the autoreportinveral using snmp, an snmp get to oid 1.3.6.1.4.1.32345.88.1.2.0 would be issued. to read the module ? s gpios through the uart or spi port, the cfg_read command would be issued with bank 1, location 2. 7.1 snmp traps WSN802G modules can generate four trap messages - request to update configuration, request to main- tain association, request to update time, and low battery warning. the port numbers used for snmp are 162 for source and 161 for destination snmp commands. a config trap is a message sent periodically to poll the snmp server to see if it has any commands wait- ing for it. after sending the trap, the module remains awake for a period of four seconds to allow the server to send it commands. by default, the module issues config traps over the wireless link every 20 seconds. config traps are sent to the snmp server address in the iphunter device discovery com- munications. the interval between config traps is a configurable parameter. the less frequently config traps are issued by the module, the longer the battery life will be, but the longer it takes to change the module ? s configuration over the wireless link. because config trap activity requires a significant amount of energy to execute, for battery-powered deployments the user should set this interval to once an hour or a few times a day to conserve battery life. at receiving a config trap, the server should immediately send a configcomplete command to indicate it has no commands to send. this allows the module to go back to sleep mode, rather than remaining in active mode for rest of the configuration window. the linkup trap is a message sent periodically by the module to maintain its association with its 802.11b/g/n access point. no information is conveyed, just "i'm here". the period of the linkup trap is set by the linkuptrapinterval system parameter. for compatibility with the majority of 802.11b/g/n routers, the default period is 10 seconds. note - this parameter should not be set above two minutes without con- tacting rfm technical support. the time sync update trap is a message requesting the time server to send updated time. windows xp and later microsoft operating systems include a time server, allowing the module to get its time from a pc. the batterywarninglevelinmvolt parameter (see table 4.14.5) sets the battery voltage level that triggers a low battery warning trap message. the default setting for a low battery warning is 2.3 v.

WSN802G will not accept sensor application commands - the module must be awake to accept applica- tion commands. either assert a logic high on the wake_in hardware line or queue the sensor application command to immediately follow an automatic (timer) i/o_report. use the rfm mib tab on the config dialog window in wsnconfig.exe to check for suitable autoreport and waketimeout values. see section 8.6 for additional information. range is extremely limited - this is usually a sign of a poor antenna connection or the wrong antenna. check that the antenna is firmly connected. if possible, remove any obstructions near the antenna.
