11.2 RS232
The EDP70 PLUS UPS is fitted with a 9 pin male ‘D’ type plug which enables a communication link to be established
between a computer and the microprocessor controller in the EDP70 PLUS UPS. The link allows the Chloride ‘EASY
PLUS’ and ‘LIFE 2000’ software to be run on an IBM compatible PC. The link also allows the communications with a
Master JBUS and Multicom/LIFE 2000 adapter.
The function of the pins on the socket are shown below:
The function of each pin is the following :
Pin 1 DCD (Data Carrier Detect)
Pin 2 RXD (Received data)
Pin 3 TXD (Transmitted data)
Pin 4 DTR (Data terminal ready)
Pin 5 GND (Ground)
Pin 6 DSR (Data Set Ready)
Pin 7 RTS (Request To Send)
Pin 8 CTS (Clear To Send)
The signals applied on each pin follows the standard EIA RS232.
