zmn2430hp firmware configurations zmn2430hp modules are shipped loaded with one of three firmware configurations: coordinator, router or end node. each zigbee network will include one, and only one coordinator. this module coordinates the overall net- work operation and is the host application or gateway interface point for the network. the part number designation for a coordinator is zmn2430hp-c . router modules are capable of retransmitting messages and provide the mesh networking infrastructure in a zigbee network. the part number designation for a router is ZMN2430HP-R . end node modules provide field connection points for sensors, data loggers, plcs, etc. the coordinator and the routers in a zigbee network must stay active (awake) continuously to support network operation. end nodes can be sleep duty cycled where needed for extended battery life operation. the part number designation for an end node is zmn2430hp-e . a router can provide the same field connection support as an end node, but a router can - not be sleep duty cycled without affecting mesh network operation. specify the number of modules for each firm - ware configuration when ordering zmn2430hp modules. www.rfm.com e-mail: info@rfm.com page2of6 ?2008 by rf monolithics, inc. zmn2430hp- 6/6/08 characteristic sym notes minimum typical maximum units adc input range 0 3.3 v adc input resolution 7 12 bits adc input impedance 55 m ? pwm output resolution 12 bits uart baud rate 1.2 115.2 kb/s digital i/o: logic low input level -0.3 0.5 v logic high input level 2.8 3.3 v logic input internal pull-up resistor 20 k ? gpio3 logic low sink current 20 ma power supply voltage range v cc +3.3 +5.5 vdc power supply voltage ripple 10 mv p-p receive mode current 33 ma transmit mode current 130 ma sleep mode current 3a operating temperature range -40 85 o c zmn2430hp electrical characteristics caution: electrostatic sensitive device. observe precautions when handling.

rfio stripline the rfio pad on the radio module is connected directly to an antenna on the host circuit board, or to an mmcx or similar rf connector. it is important that this connection be implemented as a 50 ohm stripline. referring to figure 3, the width of this stripline depends on the thickness of the circuit board between the stripline and the groundplane. for fr-4 type circuit board materials (dielectric constant of 4.7), the width of the stripline is equal to 1.75 times the thickness of the circuit board. note that other circuit board traces should be spaced away from the stripline to prevent signal coupling, as shown in figure 4. the stripline trace should be kept short to minimize its insertion loss. www.rfm.com e-mail: info@rfm.com page5of6 ?2008 by rf monolithics, inc. zmn2430hp - 6/6/08
