							Connection of SMDR - 
This system enables the output from KSU call record data for a telephone (duration of call, etc.) through the RS-232C inter- 
face. 
These data are output by the printer connected to KSU. 
Programming is necessary for outputting from KSU. (See page 48) 
0 Connection of printer 
Connect the RS-232C connector of KSU and the printer (KX-PI 08Oi) by means of the RS-232C cable. Note that because 
the printer (KX-P1080i) uses a parallel interface, KX-PIID is also necessary. See the manual for the RS-232C interface 
board (KX-PI 1 D) for how to mount KX-PI 1 D to the inside of the printers.
