Summary
This article explains the purpose and configuration of hardware jumpers on the NOP-IC2 controller. These jumpers are used for power source selection, RS-485 bus termination, and reader voltage configuration.
NOP-IC2 Jumpers
| Jumper | Label | Function |
|---|---|---|
| J1 | PoE VIN | Selects power source: DC input (default) or PoE+ (Not Utilized with NOP-N-IC2-1Mil) |
| J2 | COM1 Termination | Enables RS-485 termination for Serial Port 1 (COM1) |
| J3 | COM2 Termination | Enables RS-485 termination for Serial Port 2 (COM2) |
| J4 | RDR2 Termination | RS-485 termination for Reader Port 2 |
| J5 | VIN 12V | Selects reader voltage source (regulated 12V or passthrough from VIN) |
| J6 | RDR1 Termination | RS-485 termination for Reader Port 1 |
NOTE: All RS-485 termination jumpers ship OFF by default. Enable termination only on devices at the end of the RS-485 chain to avoid communication issues.
