Product Features
Technical Overview
This serial cable adheres to RS232 standards, featuring a DB-9 Female connector on one end and a DB-9 Male connector on the other. The 10-foot length provides flexibility in positioning devices, while the 28 AWG wire gauge balances durability with signal integrity over moderate distances.
The null modem wiring scheme crosses transmit and receive lines along with key handshaking signals, allowing two DTE (Data Terminal Equipment) devices to communicate directly. This eliminates the need for a modem or additional hardware, simplifying setup in point-to-point serial applications.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
