The LDM35 Series of products is designed to allow video display terminals (VDTs) and other RS-232 devices to be connected over distances sufficient to cover any industrial or institutional complex of buildings. These modems feature a rugged enclosure small enough to mount on the back panel of VDT units, saving valuable desk and floor space. The LDM35 Series does not require a power supply for operation. The use of low power circuits and a sensitive optical receiver allows the devices to derive all necessary power from the RS-232 data and control signal. They are designed for full-duplex, asynchronous operation over two, DC-continuity, non-loaded, twisted-wire pairs. Two-wire simplex operation may be accomplished over two wires. The modem circuits and, consequently, the host device are protected from electrical transients due to lightning strikes or operation of heavy industrial equipment. Each device features a convenient Data-Communication Equipment (DCE) to Data-Terminal Equipment (DTE) switch which reverses pins 2 and 3 of the RS-232 connector. For installation and troubleshooting, each unit has diagnostic Light-Emitting Diodes (LEDs) on the transmit and receive lines. The RS-232 connector may be ordered as a male or female 25-pin connector. Field connection is made through a modern, solderless, screw-termination assembly. Alternatively, a convenient four-wire modular phone jack is available. Model LDM35 is powered by the RS-232 data and control signals from its host computer or terminal device. It receives power from Data Terminal Ready, pin 20 or Request To Send, pin 4, and Transmitted Data, pin 2. Transmitted data may be on pin 3 when the DCE/CTE switch is in the DTE position. For proper operation, minimum required signal voltage level is ±6 V at 3.0 mA to 10.0 mA.



產(chǎn)品介紹

LDM35-P_LDM35-S信號供電的有限距離調制解調器OMEGA歐米茄

LDM35系列產(chǎn)品的設計允許視頻顯示終端(VDT)和其他RS-232設備通過(guò)足夠的距離連接,以覆蓋任何工業(yè)或機構建筑群。這些調制解調器的特點(diǎn)是堅固的外殼小到可以安裝在VDT設備的背板上,節省了寶貴的辦公桌和地板空間。LDM35系列不需要電源即可工作。低功耗電路和靈敏的光學(xué)接收器的使用使設備能夠從RS-232數據和控制信號中獲得所有必要的電源。它們設計用于全雙工、兩個(gè)以上的異步操作、直流連續性、無(wú)負載、雙絞線(xiàn)。兩線(xiàn)單工操作可以通過(guò)兩條線(xiàn)完成。因此,調制解調器電路和主機設備受到雷擊或重型工業(yè)設備運行引起的電氣瞬變的保護。每個(gè)設備都有***個(gè)方便的數據通信設備(DCE)到數據終端設備(DTE)的開(kāi)關(guān),它可以反轉RS-232連接器的插腳2和3。對于安裝和故障排除,每個(gè)單元的發(fā)射和接收線(xiàn)路上都有診斷發(fā)光二極管(LED)。RS-232連接器可訂購為25針插頭或插孔連接器?,F場(chǎng)連接是通過(guò)***個(gè)現代的,無(wú)焊,螺絲終端組件。此外,還提供了***個(gè)方便的四線(xiàn)模塊化電話(huà)插孔。LDM35型由主機或終端設備的RS-232數據和控制信號供電。它接收來(lái)自數據終端準備就緒、針腳20或發(fā)送請求、針腳4和發(fā)送數據針腳2的電源。當DCE/CTE開(kāi)關(guān)處于DTE位置時(shí),傳輸的數據可能位于插腳3上。為了正常工作,3.0 mA至10.0 mA時(shí)所需的***小信號電壓水平為±6 V。
