7.1 Using Serial Port

Two serial communication port is included on DS300H Series UPS cabinet (com1 and com2). Both of them

port in Options Menu.
All data of UPS can be accessed by this communication way. All the voltage and current values measured
by UPS, alarms, warning and status messages can be monitored.

monitoring and control units. These commands are listed below:
• Switch to BYPASS
• Switch to INVERTER
• SOUND on/off
• Adjust UPS time and date
• Quick BATTERY TEST
• BATTERY TEST until battery low alarm
• CANCEL battery test
• Turn off UPS output voltage immediately (SHUTDOWN)
• Turn off UPS output voltage after delay (WAITING SHUTDOWN)
• Turn off UPS output voltage (SHUTDOWN) and turn on UPS output voltage (WAITING RESTART)
• CANCEL SHUTDOWN
• RENAME UPS
