Notes

This is a legacy interface and generally supported only with native COM1/COM2 serial ports (not with USB‑to‑serial adapters); check Rockwell’s notes before purchase.
Intended for maintenance of existing SLC 500/DH‑485 systems; newer installations typically use 1747‑UIC USB‑to‑DH‑485 converters instead.
Buyer should verify compatibility with their specific PLC model, programming software version (e.g. RSLogix 500), and PC hardware/OS.
