Black Box Parallel Extender III Output PI322A-R3
The Black Box PC Parallel Extender III (Model #PI322A-R3) is a legacy hardware device manufactured by Black Box Corporation that allows standard parallel printer signals to be extended over long distances (up to thousands of feet) using standard twisted-pair CAT5, CAT5e, or CAT6 cables.
Key Specifications & Use Cases
- Model Type: Parallel Output Extender III
- Transmission: Extends standard parallel port connections well beyond the standard \(6\)-foot to \(10\)-foot limitation.
- Cable Type: Utilizes unshielded twisted pair (UTP) CATx cables for the extension run.
- System Requirements: Typically requires a matching local unit (such as the PI321AE-R3 or part of a PI320A-R3 set) to convert the signal at the PC end, and an external AC power supply.
