haritha Posts: 2 Rating: (0)	Hello, I'm using cp 340 RS232C module with EPSON LX-300+II printer. (PLC used is S7-300 CPU313-6BF03-0AB0). I tried the example given in the CP_PTP_PARAM cd. when i triggered M 1.0 as given in the example, TXD and RXD indicators at cp340 blinking. But, print job is not proceeded. At this stage i also checked with Hyperterminal and free serial port monitor and they also do not indicated any data transmission. Cable was ok when connected with the pc. Pls find the example program with the attachment. Thnx. Attachment CP 340 Getting Started Printer.pdf (174 Downloads)
