SANWA SUPPLY RS-232C cable

This is a D-sub25pin cable for connecting the serial (D-sub9pin) port of a DOS/V computer and the RC-232C connector of the NEC PC-9821 series, etc., for data transfer. A double-shielded cable with a sealed aluminum shield inside a copper high-density braided shielding material. Protects important data from most noise from low to high frequencies. Uses a noise-resistant twisted pair wire that twists two core wires together. With metal treatment, it is resistant to external noise, and is a perfect FCC countermeasure against electromagnetic interference (EMI). The cable shell can be removed and the internal wiring specifications can be changed. *The Centronics connector is a metal shield connector. Contact noise is shut out by using a machined pin conforming to the US MIL standard. Of course, it is gold-plated to resist signal degradation due to rust and aging.
