Common binary mode In this mode the input detects the close open state of the contact The state is detected only in case of wake up the module by Measuring timer and it is stored in the internal logger if enabled This is the basic mode of binary input operation Alarm mode Basically this mode differs from the common mode in an immediate detection of contact closing which results in the immediate module wake up Then the module runs the measuring cycle and process the rules It ensures the asynchronous i e independent on Measuring timer transmission of alarm information Neither the measured value nor the input activation event are stored in the internal logger Additionally neither the crossing of alarm thresholds on analog inputs nor the increments and alarm level crossing on totalizers are evaluated Therefore in this mode the rules cannot be triggered by flags which are set for analog alarm levels and for value increments in the totalizers Counter mode Despite of the basic function this mode features pulse counting as well Pulses are counted with different weights which are set by the user 1 10 100 or 1000 The non volatile 32 bit wide register is used to count the pulses providing the maximum count of 4 294 967 296 pulses If the counting function is enabled the difference between the previous and the current status of the totalizer can be calculated This also gives the information about the totalizer content increment If the

16. stand by mode of the module It seems the module in such state is inactive but in fact it executes the program provided for this mode The blinks help to evaluate the proper operation of the module without its activation thus without additional energy consumption Secondly the LED indicates the strength of a GSM signal passing from the antenna to the module This strength is indicated by a blink series repeated every 5 seconds when the module is active The number of blinks is proportional to the intensity of the signal so it means the more blinks the better are chances for a proper module operation The lack of blinks during login to the network means that signal strength is too low and cannot guarantee a correct operation 2006 INVENTIA 44 MT 703 User Manual The USB LED serves as an indicator of a USB cable connection between the PC and the module This link has two functions First it is the link used for transmission of configuration data and second it is a medium for powering the module during configuration process Such solution ensures that even the long process of establishing the correct parameters of the MT 703 module does not require the energy from batteries 7 2 Unlocking the SIM card As it is generally known three attempts of entering a wrong PIN number make a SIM card locked and unlock operation requires the knowledge of a PUK number To avoid such situation the module checks the number
