Question about Casio Parts Cash Register PC Desktop
I have installed a USB 2.0 to RS232 to connect my Samsung ER-650 till to my vista lap top, and keep getting an error message- Cannot access port
Windows Vista is the last operating system that you would want to use for legacy hardware -legacy being anything that requires a usb to rs 232c adaptor. Scripts required to make this work would drive you to an abacus. If you need to have a cash register input on a permanent basis I would recommend another operating system, even a real old computer would be easier to interface or you could use the modem output of the Samsung to connect to your laptop in a LAN configuration maybe even with a null modem connection. Vista will drive you crazy with permission denials with cries of cyber-sodomy with an analog interface directly connected. The Samsung 755 has a USB interface but since you don't have the correct input for your laptop it will be far easier to use the cash register an an old (cheap) computer with an RS 232 interface and connect it to your laptop with a wired or wireless LAN configuration. Those USB to DB9 0r DB25 or PS2 adaptors still cannot match the speed parameters that the laptop US Host controller would ever find acceptable. Windows XP or 2000 might be a consideration but Vista is already neurotic enough without interfaces it was not designed to accomodate. I hope this will save you from alot of frustration. respectfully, Steve Medley
