The Allen-Bradley 1745-PCC is an essential interface converter in the SLC personal computer interface kit, facilitating seamless communication between personal computers and the SLC 100 and SLC 150 series programmable controllers. It efficiently converts RS-422 signals from SLC processors to RS-232-C signals for compatibility with personal computers, while isolating the SLC processor to safeguard it against noise transients from the computer's serial port. For connectivity, it utilizes a 6-foot cable linked to the SLC processor and requires a 25-pin to 9-pin adapter for computers equipped with 9-pin RS-232 ports. Significantly, Series A SLC 100 processors support communication up to 100 feet, whereas Series B SLC 100 processors, Series A SLC 150 processors, and later models extend this range to 4000 feet.
