3. Application Note 3.1 INIT* pin Operation Each I-7000 module has a build-in EEPROM to store configuration information such as address, type, baudrate and other information. Sometimes, user may forget the configuration of the module. Therefore, the I-7000 have a special mode named “INIT mode”, to help user to resolve the problem. The “INIT mode” is setting as Address=00, baudrate=9600bps, no checksum To enable INIT mode, please follow these steps: Step1. Power off the module Step2.

3.3 Dual Watchdog Operation Dual Watchdog = Module Watchdog + Host Watchdog The Module Watchdog is a hardware reset circuit to monitor the module’s operating status. While working in harsh or noisy environment, the module may be down by the external signal. The circuit may let the module to work continues and never halt. The Host Watchdog is a software function to monitor the host’s operating status. Its purpose is to prevent the network/communication from problem or host halt.

3.6 High/Low Alarm Some analog input modules, like I-7011, equip with the high/low alarm function. When the alarm function is enabled, the digital output DO0 is the low alarm indicator, DO1 is the high alarm indicator, and the digital output command for changing digital outputs DO0, DO1 is ignored. The alarm function is to compare the analog input value with given high alarm value and low alarm value.

To measure the Seebeck voltage directly is not available because we must first connect a voltmeter to the thermocouple, and the voltmeter leads themselves create a new thermoelectric circuit. Therefore we need to eliminate the junction thermoelectric to measure the correct Seebeck voltage, and this is called “Cold Junction Compensation”. For most thermocouples, the Seebeck voltage is 0V while in 0°C.
