WIT2492 RFM/Cirronet Inc 2 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 Description 1 GND - Signal and chassis ground 2 TXD Input Transmit data. Input for serial data to be transmitted. In Control Mode also used to transmit modem commands to the modem. 3 RXD Output Receive data. Output for received serial data. In Control Mode, also carries receive modem status from the modem. 4 Input 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) 1 = Control Mode (3.3v) 0 = Data Mode 5 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) 1 = Receive data (RxD) enabled (3.3v) 0 = Receive data (RxD) disabled. 6 SLEEP Input 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) 1 = Sleep Radio (0v) 0 = Wake Radio 7 Output Data carrier detect. For remotes, indicates the remote has successfully acquired the hopping pattern of the base station. (0v) 1 = Carrier detected (synchronized) (3.3v) 0 = No carrier detected (not synchronized) 8 Output 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 9 - - Reserved for future use. Do not connect. 10 Input Resets the radio. 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. RTS DCD CTS CFG Reset

Serial Connector Pinouts Signal WIT2492M/S4 OEM Pinout HN-510 DB9 Pinout GND 1 5 TXD 2 3 RXD 3 2 CFG 4 - RTS 5 7 SLEEP 6 4 DCD 7 1 CTS 8 8 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.
