Exclusion Zone Figure A 2 RCM5400W Exclusion Zone NOTE There is an antenna associated with the RCM5400W RabbitCore modules Do not use any RF absorbing materials in these vicinities in order to realize the maximum range The RCM5400W modules were tested for heat dissipation over the specified operating temperature range and normal heat dissipation by convection was found to be adequate If you plan to use RCM5400W modules in a tightly enclosed space additional forced air cooling will likely be needed If you are planning to mount your RCM5400W directly in a panel mounted enclosure the RP SMA antenna connector will extend outside the enclosure Keep the thickness of the enclosure plus washer and lock nut to less than 0 2 5 mm to make sure that the antenna can be mounted securely in the RP SMA antenna connector OEM User s Manual 79 Table A 1 lists the electrical mechanical and environmental specifications for the RCM5400W Table A 1 RCM5400W Specifications Parameter RCM5400W RCM5450W Microprocessor Rabbit 5000 at 73 73 MHz Data SRAM 512K 512K Program Execution Fast SRAM 512K 1MB Flash Memory 512K 1MB Serial Flash Memory 1MB 2MB Backup Baten ao e a General Purpose I O Es ne a 1 0 lines configurable with four layers Additional Inputs Startup mode 2 reset in Additional Outputs Status reset out Can be configured for 8 data lines and External

15. 1 1 Infrastructure Mode The infrastructure mode requires an access point to manage devices that want to communi cate with each other An access point is identified with a channel and service set identifier SSID that it uses to communicate Typically an access point also acts as a gateway to a wired network either an Ethernet or WAN DSL cable modem Most access points can also act as a DHCP server and provide IP DNS and gateway functions When a device wants to join an access point it will typically scan each channel and look for a desired SSID for the access point An empty string SSID will associate the device with the first SSID that matches its capabilities Once the access point is discovered the device will logically join the access point and announce itself Once joined the device can transmit and receive data packets much like an Ethernet based MAC Being in a joined state is akin to having link status in a 10 100Base T network 802 11b g interface cards implement all of the 802 11b g low level configurations in firm ware In fact the 802 11b g default configuration is often sufficient for a device to join an User s Manual 55 access point automatically which it can do once enabled Commands issued to the chip set in the interface allow a host program to override the default configurations and execute functions implemented on the interface cards for example scanning for hosts and access points 6 1 2 Ad Hoc
