NCR 7875 Scanner/Scale Communication problem with PC

Hello,
I just purchased a used 7875 Scanner/Scale. I need a RS 232 Interface to work with my regular Windows XP desktop, where I run Cash Register Express. As it did'nt come with a cable I used my old Metrologic Serial interface cable. Im having trouble comunicating with the PC. When I run Diagnostics with the NCR Opus Driver is states Fatal error Timed out. I set the protocol to RS 232 on the scanner and made sure the parity and bit match Scanner/Desktop. Can anybody tell me what might be wrong? Can it be that the cable is incorrect? Does anybody have a Part Number for the correct cable or how the pinout schould be? I've contacted NCR and they insist in sending out for a service call, which I would like to prevent. I can't get them to tell me what cable to use, nor what to look out for

Any help or suggestions would will be greatly appreciated.
Thank you,
Nicolas

    Thank you for your reply. I was thinking the same and finally found the part number for the cable and a supplier. Once I have it installed I will let you know how if everything is working.



    Thank you

You need another cable (the metrologic cable doesnt work with the same configuration) and set the button in the interface card to rs-232 and program the scanner-scale with the programing tags.

Was it a cable issue? I am having the exact same problem and think it could be a cable issue? Do you still have the part number to the cable?

Ncr Scanner 7875-2000 I bought this scanner used and it came with a USB cable,not an NCR cable, I tried to have it communicate with the pc but could not get it to read, i got calibrated and I know it...


Hmmmm.... It sounds as though your scanner is not programmed correctly. Either RS232 or IBM... Either way it sounds as though it is not accepting your communication entry. Which could be your Eeprom chip, a digital board, maybe even the dual I/O board, in most cases.
