Your UPS is fitted with a standard RS232 interface, which can be used in conjunction with a computer in order to access
data relating to the operation of the UPS and its log. This function must be used together with the interface programme
for WINDOWS environments available from our website www.ups.legrand.com without charge.
A RS232 cable is required to connect a serial port on your PC to the interface outlet [11] located on the rear of the UPS.
