[ CABLE / ADAPTER RECORD // IEEE 1284 TYPE A HOST CABLE ]
IEEE 1284 Type A DB-25 Parallel Extension Cable
DB-25 straight-through parallel wiring for host/peripheral or extension use; data/control/status pins remain separate parallel signals.
CLASSIFICATION: Legacy printer and parallel cables. Identify protocol, direction, pinout and exact cable revision before connection.
Interface and capability
| Standard / protocol | IEEE 1284 Type A host cable. Connector appearance alone does not establish compatibility. |
|---|---|
| Endpoint / pinout | DB-25 straight-through parallel wiring for host/peripheral or extension use; data/control/status pins remain separate parallel signals. |
| Capability / limits | Mode performance and usable total cable length depend on IEEE 1284 compliance and endpoints; avoid chained extensions. |
| Certification / length | Standards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology. |
Compatibility & handling
- This does not convert to USB or change protocol. Prefer one shielded, compliant cable; verify gender and pin continuity.
- Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
- Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
