Main Functions

1. ISA‑bus carrier hardware for µGENI daughter‑board IC660ELB912(J), provides mechanical mounting and power supply for daughter‑board.
2. Realizes electrical signal conversion between host ISA bus and Genius field‑bus physical layer, provides Genius‑bus field‑wiring terminal interface.
3. On‑board jumpers configure ISA memory base address and Genius‑bus baud‑rate, consistent with Genius‑bus slave devices.
4. LED status indication:   ‑ Green GENI‑OK：µGENI daughter‑board power‑on and self‑test pass   ‑ Green COMMS‑OK：Genius‑bus communication activity normal

Installation & Wiring Requirements

1. Completely cut off industrial‑PC main power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling board.
2. Insert IC660ELB921M into PC ISA slot and fasten bracket screw; install IC660ELB912(J) daughter‑board onto PCIM; set memory‑address and baud‑rate jumpers according to project configuration.
3. Genius‑bus wiring strictly follow GE Genius hardware manual; use shielded twisted‑pair Genius‑bus cable; install terminating resistor at two physical ends of bus trunk; separate bus signal cables from high‑power cables, connect shielding to dedicated protective ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: power‑on industrial PC, verify GENI‑OK & COMMS‑OK LED status, load Genius driver software, perform bus‑scan and full I/O‑loop commissioning test.
6. Replacement note: Verify ISA address no conflict with other PC peripheral cards; daughter‑board hardware revision compatibility check; full Genius‑bus‑loop simulation test mandatory before unit put‑into‑service.
