Specifically engineered to bridge RS-232 serial ports to the RS-485 DH-485 industrial network, this unit provides a reliable physical layer conversion for legacy automation architectures. It is primarily utilized for program uploading, downloading, and online monitoring of SLC 5\/01, SLC 5\/02, and SLC 5\/03 processors.\u003c\/p\u003e\n\u003cp\u003eThis converter requires a direct hardware connection to native, built-in computer COM ports supporting standard UART protocols. It operates independently of complex operating system driver layers when paired with compatible 32-bit software environments, making it a foundational tool for legacy plant floor maintenance and commissioning.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts RS-232 signals to RS-485 DH-485 communication standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with Allen-Bradley SLC 5\/01, SLC 5\/02, and SLC 5\/03 processors\u003c\/li\u003e\n  \u003cli\u003eIntegrated 11-inch ribbon cable for convenient physical connection to processor communication ports\u003c\/li\u003e\n  \u003cli\u003eLow power consumption profile rated at a maximum of 2 watts\u003c\/li\u003e\n  \u003cli\u003eDirect hardware-level pass-through eliminating complex protocol translation overhead\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLegacy Allen-Bradley SLC 500 system programming and configuration\u003c\/li\u003e\n  \u003cli\u003eDH-485 network troubleshooting and node connection\u003c\/li\u003e\n  \u003cli\u003ePlant floor maintenance utilizing older programming terminals with native serial ports\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number \/ SKU\u003c\/td\u003e\n      \u003ctd\u003e1747-PIC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eRS-232 to RS-485 Interface Converter\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSupported Processors\u003c\/td\u003e\n      \u003ctd\u003eSLC 5\/01, SLC 5\/02, SLC 5\/03 (DH-485 network)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSource Interface\u003c\/td\u003e\n      \u003ctd\u003eRS-232 (DH-485 \/ AIC+ compatible)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDestination Interface\u003c\/td\u003e\n      \u003ctd\u003eRS-485 (DH-485 network)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Consumption\u003c\/td\u003e\n      \u003ctd\u003e2W max\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCable Length\u003c\/td\u003e\n      \u003ctd\u003e11 inches (ribbon cable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eUnited States\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConnections \/ Interfaces\u003c\/h3\u003e\n\u003cp\u003eThe 1747-PIC features a physical interface configuration tailored for legacy industrial computing standards:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComputer Side:\u003c\/strong\u003e RS-232 connection requiring a native, physical serial port (COM port).
