TECHNICAL DETAILS Input Voltage: 3.3 - 5. Note: This module does not come with battery. When the main power re-powers or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected. low-voltage battery) to switch between the power supply. On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e. The device integrates a very precise digital temperature sensor, accessible through the I2C interface. RST pin is monitored as generating μP reset manually. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply. Address and data are transferred serially through an I2C bidirectional bus. It provides two configurable alarm clock and a calendar can be set to a square wave output. Clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. For months with less than 31 days, the end date will be automatically adjusted, including corrections for leap year. The clock module maintains seconds, minutes, hours, day, date, month, and year information. It has an integrated oscillator to improve long-term accuracy of the device. The clock module incorporates a battery input which maintains accurate timekeeping even without a power supply. ![]() ![]() DESCRIPTION This clock module DS3231 RTC is low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.

Step 5: In order to open the SQL command line, enter sqlcmd and hit Enter key Once “The SQL Server service was started successfully” appears, it means that it is started Step 4: Then, type net start MSSQLSERVER -m”SQLCMD” and press Enter to restart SQL server in Single-User mode. Step 3: To stop SQL instance from running, type net stop MSSQLSERVER command and hit the Enter key Step 2: Now, press Windows+R keys and type cmd on the run box. Step 1: To begin with, make sure that SSMS (SQL Server Management Studio) is installed on your system. After which, you can access using the new user’s credentials to login into SQL server page from where you can reset user login password in Microsoft SQL server. You can add a new user providing with the administrator permissions via command prompt. Here, even if you are locked out from your account. # Method 2: Reset User Password in SQL Server Using Single-User Mode But, this time use the new user login password that you setup in just previous step. Step 7: Now, again login with the same user name. Step 6: Under the Login Properties, go to the Password Section and input the new password and confirm it and click on OK to save the changes. Right- click on it and opt for Properties to change password in SQL Server. Step 5: Under Logins folder, right-click on the User Login whose password you want to reset. Step 4: In order to reset password in SQL server, under Object Explorer, expand the folders to open Security folder from that open Logins folder. Step 3: Then, select the Authentication drop-down list and choose Windows Authentication from the menu. Step 2: In the Start box, type SQL Server Management Studio and from the top of the Start window and click on Microsoft SQL Server Management Studio 17.
