[ching99 0]

Hi, I have 1747-PSD (Series A) and would like to connect to PC for uploading / downloading program file, also to SLC 5/03. I have 1747-UIC cable. I have USB to Serial Converter. I also make 1747-CP3 cable base on pinout (1-1, 2-3, 4-6, 5-5, 7-8, link 1 and 6 for both connectors). My PC have USB port but don't have Serial Port. My PC installed with RSLogix 500 (Version 7.1) and RSLinx 2.57. Connection: 1) PC (USB-Serial Converter) to Cable 1747-CP3 to 1747-PSD, but can't detect the device. 2) SLC 5/03 (RS232 port to Cable 1747-CP3 to 1747-PSD, but can't detect the device. Is there wrong cable / connection / configuration in RSLinx / configuration in Program file? Appreciated your kindly help. Best Regards, HSC

I have never used a 1747-PSD, bur your 1747-CP3 pin-out does not look right. See pdf below Pins 2,3 and 5 on both sides are all you really need. 1747-CP3_1756-CP3-PinOut.pdf Edited 11 Aug 2013 by Mickey

Thank you Mickey. I make the cable according to your pinouts. If cable is right, then it may be wrong setting in RSlinx or com port or program file.
