Intelligent Monitoring MIC-3920/3921 and Alarm Module F e a t u r e s  Monitoring: +3.3 VDC, +5 VDC, +12 VDC, -12 VDC system bus voltages  Four fan sense inputs for fan speed monitoring  Three temperature sensor inputs  One "power good" signal input for power supply monitoring  Three channels of relay outputs for external alarm connection  One serial port can be set as RS-232 or RS-485 port, supporting modem output  Three configurable alarm levels: critical, major, minor  Audible alarm with three sound effects  On-board battery backup  Built-in watchdog timer for self-detection Introduction The MIC-3920/MIC-3921 is an intelligent PC-system monitoring module. High Reliability It can detect abnormal system conditions and generate alarm outputs, To ensure operational reliability, the MIC-3920/MIC-3921 features a built- allowing users to take action before system failure. With the in watchdog timer for self-testing. The on-board backup battery enables MIC-3920/MIC-3921, the MIC-3031, MIC-3032, MIC-3033, and MIC- non-stop operation even in the event of total system power failure. 3081A systems are changed into intelligent, self-diagnostic systems, increasing the reliability of critical applications, such as in communications Remote Monitoring or computer telephony. The alarm module comes in two versions: the The MIC-3920/3921 serial port can be configured either as RS-485 to MIC-3920 and the MIC-3921. The MIC-3920, using front panel LEDs for communicate over distances up to 4000 feet, or as RS-232 to connect to status display, is a 3U high, 2-slot (8TE) wide module which can be inserted other devices such as a modem. Users can remotely monitor a number into the MIC-3033. The MIC-3921, equipped with a of computers through a host computer's serial port. high-brightness vacuum fluorescent display and a control keypad, can be inserted into the MIC-3031, 3032, and 3081A. Software Support Powerful Functions The MIC-3920/MIC-3921 is shipped with a powerful and easy-to-use software utility to minimize the time for system integration. "PC Sentry" The MIC-3920/MIC-3921 can detect a wide variety of internal system can run under Windows 95/98/NT. This allows the system host to conditions including temperatures, voltages, fan operation and power communicate with one or more alarm modules via the serial port, for supply status. It can generate several different alarm outputs including configuration, alarm level setting, real-time status display, alarm event acoustic signals and relay outputs to notify nearby users. It can also send logging and so on. messages through the serial port for remote notification. The on-board CPU allows users to set the alarm criteria for each input sensor independently and to program different alarm outputs.
