NOTE 1: write always 0x0000 in “Command Code” after executing a command in order to get ready the device to accept the next
command.
NOTE 2: before executing a new command, you can check if the device is ready to accept it by verifying that Command Result =
0x0F00 (INPUT DATA register 59)
NOTE 3: write in register 1 and 2 (“Shutdown delay time” and “Restore delay time”) before writing in register 0 for executing a system
shutdown or a system shutdown & restore otherwise, writing in register 1 and 2 will have no effect.
Example of Power OFF the UPS in 3 minutes and Power ON after 8 hours (System Shutdown & Restore):
•Check that "Command Result" (INPUT DATA register 59) is equal to 0x0F00.
•Write 0x00B4 in Shutdown delay time (output data / register 1)
•Verify that "Echo of shutdown delay time" (INPUT DATA register 57) is equal to the value sent.
•Write 0x01E0 in Restore delay time (output data / register 2)
•Verify that "Echo of restore delay time" (INPUT DATA register 58) is equal to the value sent.
•Write 0x0002 in Command Code (output data / register 0)
•Verify that command result is 0x0E02 (input data / register 59)
•Write 0x0000 in Command Code (output data / register 0)
