RFM/Cirronet Inc WIT2492 WIT2492 Labeling and Notices Labeling: A clearly visible label is required on the outside of the user’s (OEM) enclosure stating the following: ”Contains FCC ID: HSW-2492” ”Contains IC: 4492A-2492” Notices: WARNING: This device operates under Part 15 of the FCC rules. Any modification to this device, not expressly authorized by RFM, Inc., may void the user’s authority to operate this device. FCC NOTICE: This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IC Notice - This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter, IC: 4492A-2492, has been approved by Industry Canada to operate with the antenna types listed later in this manual with the maximum permissible gain and required antenna impedance for each antenna type indicated. Canadian ICES-003 - This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of Industry Canada. Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites applicables aux appareils numeriques de Classe B prescrites dans le reglement sur le brouillage radioelectrique edicte par Industrie Canada. Canadian Department of Communications Industry Canada (IC) Notice Canadian Department of Communications Industry Canada (IC) Notice This apparatus complies with Health Canada’s Safety Code 6 / IC RSS 102. "To prevent radio interference to the licensed service, this device is intended to be operated indoors and away from windows to provide maximum shielding. Equipment (or its transmit antenna) that is installed outdoors may be subject to licensing." RFM/Cirronet Inc WIT2492 WIT2492 1. INTRODUCTION The WIT2492 radio transceiver provides reliable wireless connectivity for either point-to-point or multipoint applications. Frequency hopping spread spectrum technology ensures maximum resistance to noise and multipath fading and robustness in the presence of interfering signals, while operation in the 2.4GHz ISM band allows license-free use and worldwide compliance. A simple serial interface supports asynchronous data up to 921600 bps. An on-board 3 KB buffer and an error-correcting over-the-air protocol provide smooth data flow and simplify the task of integration with existing applications. Multipath fading impervious frequency hopping technology with 43 frequency channels (2401-2475 MHz). Supports point-to-point or multipoint applications. Built-in data scrambling reduces possibility of eavesdropping. Nonvolatile memory stores configuration when powered off. Smart power management features for low current consumption. Dynamic TDMA slot assignment that maximizes throughput. Meets FCC rules 15.247 and ETS 300.328 for worldwide licensefree operation. Superior range to 802.11 wireless LAN devices. Transparent ARQ protocol w/3KB buffer ensures data integrity. Digital addressing supports up to 64 networks, with 62 remotes per network. Low power 3.3v CMOS signals Simple serial interface handles both data and control at up to 921600 bps. Fast acquisition typically locks to hopping pattern in 2 seconds or less. Selectable 10 mW or 100 mW transmit power. Support for diversity antenna. RFM/Cirronet Inc WIT2492 WIT2492 4. MODEM INTERFACE Electrical connection to the WIT2492 is made through a 16-pin male header on the modem module. The signals are 3.3 volt signals and form an RS-232 style asynchronous serial interface. The table below provides the connector pinout. Pin Signal Type GND TXD Input RXD Output CFG Input Description Signal and chassis ground Transmit data. Input for serial data to be transmitted. In Control Mode also used to transmit modem commands to the modem. Receive data. Output for received serial data. In Control Mode, also carries receive modem status from the modem. Configuration selector. Used to switch between Control and Data Modes. Normally, CFG will be set for Data Mode. An internal 10K pull-up enables Data Mode if this signal is left unconnected. Control Mode is also accessible by transmitting an escape sequence immediately after wake up or power up. (0v) (3.3v) RTS Input Request to send. Gates the flow of receive data from the radio to the user on or off. In normal operation this signal should be asserted. When negated, the WIT2492 buffers receive data until RTS is asserted. (0v) (3.3v) SLEEP Input DCD Output 1 = Receive data (RxD) enabled 0 = Receive data (RxD) disabled. Sleeps/wakes radio transceiver. In sleep mode all radio functions are disabled consuming less than 50µA. At wake up, any user programmed configuration settings are refreshed from non-volatile memory, clearing any temporary settings that may have been set. (3.3v) (0v) 1 = Control Mode 0 = Data Mode 1 = Sleep Radio 0 = Wake Radio Data carrier detect. For remotes, indicates the remote has successfully acquired the hopping pattern of the base station. (0v) (3.3v) 1 = Carrier detected (synchronized) 0 = No carrier detected (not synchronized) CTS Output 10 Reset Input 11-15 Reserved for future use. Do not connect. 16 VCC Positive supply. Min 3.3 v, 5.0 v nominal, 10.0 v max. RFM/Cirronet Inc Clear to send. Used to control transmit flow from the user to the radio. (0v) 1 = Transmit buffer not full, continue transmitting (3.3v) 0 = Transmit buffer full, stop transmitting Reserved for future use. Do not connect. Resets the radio. WIT2492 WIT2492 9.

Serial Connector Pinouts Signal GND TXD RXD CFG RTS SLEEP DCD CTS WIT2492M/S4 OEM Pinout HN-510 DB9 Pinout Note: The WIT2492M4 is the standard part number and has the serial connector pins pointing down allowing connection to a mother board without using a cable. WIT2492S4 has the serial connector pins pointing up. The HN-510 is wired as a DCE device and as such can be connected to DTE devices such as PCs with a straight-through cable. When connecting a HN-510 to a DTE device, a “null modem” cable is required. To effect a null modem cable, cross-wire TXD and RXD and connect ground. The HN-510 can operate with just these three wires connected. However, as the WIT2492 does not support software flow control, there will be no flow control in this mode. If the DTE device fails to respond, connect DCD from the HN-510 to the DTR and RTS inputs to activate the DCE device whenever the WIT2492 asserts carrier. When connecting to the WIT2492M/S4, make sure that all of the inputs (TXD, CFG, RTS and SLEEP) are terminated for proper operation. 9.3. Approved Antennas The WIT2492M/S4 is designed to ensure that no antenna other than the one fitted shall be used with the device. The end user must permanently affix the antenna by using an adhesive on the coupling such as Loctite, or ensure the antenna has a unique coupling. The table below lists the antennas which can be purchased directly from Cirronet. Contact Cirronet Technical Support with any questions.
