The User Manual recommends a bunch of Allen-Bradley part numbers, including the 1747-CP3, to connect the RS-232 port of the 1747-UIC to your SLC-5/03 serial port. http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1747-in063_-en-p.pdf The 1747-CP3 is a "null modem" type cable, so pins 2 and 3 are swapped and pin 5 goes straight through. You can find the complete wiring diagram in the RA Knowledgebase. For the RS-485 side, the cable is a 1747-C13. These can be purchased through Allen-Bradley, or the pinout is also available on the RA Knowledgebase.
