The P454-006 from Tripp Lite is a 1.83‑meter null‑modem serial cable equipped with DB9 connectors, featuring a male end and a female end as indicated by the (DB9 M/F) designation. Designed for direct cross‑connection of two serial devices, this cable swaps the transmit and receive lines to enable communication without the need for an external null‑modem adapter. Its 1.83 m (approximately 6 ft) length provides flexibility for installations where devices are spaced a moderate distance apart. Constructed to Tripp Lite’s standard quality, the cable offers reliable, plug‑and‑play connectivity for compatible RS‑232 equipment.
