FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What power source is typically used to operate the Allen-Bradley 1747-PIC interface converter?

A: The module is typically powered by the handshake lines (DTR/RTS) of the connected PC's RS-232 port.

Wiring & Installation:

Q: What type of cable is required to connect a PC to the 1747-PIC converter's 9-pin D-shell port?

A: A straight-through RS-232 cable is required to establish the physical connection to the PC.

Troubleshooting & Compatibility:

Q: What does it indicate if the DH-485 LED indicator on the 1747-PIC is not illuminating?

A: It indicates a connection or power issue on the DH-485 network side of the interface.

Replacement & Upgrades:

Q: Which communication protocol does the 1747-PIC convert the PC's RS-232 signal into for the PLC network?

A: It converts the signal to the DH-485 protocol, which is a peer-to-peer network standard.
