designed to provide oems with license-free communications over long dis - tances, ac4868 becomes the essential, affordable alternative to products operating in the saturated 433mhz band. the fully certified 868mhz trans - ceiver delivers 250mw of output power , ideal for highly industrial european applications where reliable data deployment is crucial. ac4868 supports a host of communication architectures: point-to-point, point- to-multipoint and peer-to-peer . its dynamic serial firmware manages dif ficult over- the -air iss ues suc h as err or det ect ion, m ultipat h conce rns, link v erif icat ion and int erf ere nce. i t is sim ply the bes t pric e/per for man ce 8 68mhz av ailable. ac4868 modules are socket-compatible with aerocomm s 900mhz or 2.4ghz transceivers, enabling oems to design once and subsequently inter - change radios to accommodate new markets, regulations and environments. european approval allows use of the transceiver in both mobile and fixed installations without further licensing requirements. approved for european use. seamless cable-to-transceiver replacement. high 868mhz data rate: 57.6 kbps. small form factor: 1.65 x 1.9 inches. operates in ?0? to +80? temperatures. 250mw enables up to 15-kilometer range. recreation areas irrigation systems golf cart tracking score keeping order entry grounds maintenance pool & spa control t empe rature mon ito r i ng p um p a c t ivat io n illumination ? environmental controls access & activity alerts point of sale inventory tracking order processing credit/debit verification merchandise vending portable registers gaming devices lottery machines portable bingo bar trivia casino slots game kiosks p a r a m e t e r a c 4 8 6 8 ?2 5 0 interface 20-pin mini connector frequency 869.40?69.65mhz modulation sf fsk serial interface options 3v ttl serial interface data rate up to 57.6 kbps output power (w/ 2dbi antenna) 250mw variable power consumption (transmit/receive) 240ma/36ma security one-byte system id sensitivity (w/ 2dbi antenna) -103 dbm typical @28.8 kbps v oltage pin 10: 3.3-5.5v +/?0mv ripple pin 1 1: 3.3v +/?%, +/?00mv ripple range up to 15 kilometers line of sight t emperature -40 o to +80? humidity (non-condensing) 10% to 90% dimensions 1.90 x 1.65 x 0.20 inches (49 x 42 x 5 mm) w eight < 0.75 oz (< 21 g) antenna external mmcx connector * the 868mhz frequency band is approved in europe as an unlicensed spectrum subject to approval by device. ** although ac4868 radios will not talk to ac4490 radios, socket-compatibility allows for interchanging the modules network-wide. utilities management aut omat ic m eter r e adi ng lo ad prof il i ng, fo recasti ng data management t ampering alerts real-time support
aerocomm s embedded transparent protocol simplifies the oem? integration process by allowing for drop-in installation. as each transceiver receives raw data, it manages over-the- air protocol to assure successful communication. headers, data packet length, and crcs are not needed. rf232 supports simple cable-replacement to complex peer- to-peer configurations. broadcast communication to all trans - ceivers or address packets to a specific destination using unique mac addresses embedded in each transceiver . r f p r o t o c o l m o d e s a) communication unicast (one-to-one addressing) broadcast (one-to-many addressing) b) acknowledgement mode (ack) api wi th h ard wa re /so ftware ack ind ica tion i n t e r f a c e p r o t o c o l a) on-the-fly transceiver configuration destination address rf transmit power broadcast/addressed b) 9-bit serial interface mode c) a/d, d/a generic i/os d) v ariable baud rate e) rf packet size, timeout control f) onboard temperature sensor g) handshaking c t s / rt s h) in-range indicator i) error detection on bo a rd cr c du plica te p a ck et filter i n g j) data encryption standard (des) flexible rf protocol rf architectures protocol features point-to-point point-to-multipoint multipoint-to-multipoint s e l ec t f e at u r e s from t h e li st below to i de nti fy the app r o pri ate part n umber . mo r e pro duct lines are available for industrial & commercial applications. contact aerocomm sales for details: toll-free 1-800-492-2320, email sales@aerocomm.com . p a r t n u m b e r s a c 4 8 6 8 - 2 5 0 m 868mhz transceiver , ttl serial rs232, 0?50mw , -40? to +80? c, mmcx antenna a c 4 8 6 8 - 2 5 0 m - 4 8 5 868mhz transceiver , ttl serial rs485, 0?50mw , -40? to +80? c, integral antenna placing orders ac4868, actual size
