  • Externally AC Powered

The Patton Model 2040 V.35 to High Speed Serial Interface (HSSI) converter lets a HSSI (HD-50) device communicate bi-directionally with a V.35 (M/34) device at synchronous data rates up to 10 Mbps. The Model 2040 supports all HSSI co-directional timing patterns, two loopback modes (local line and remote line), plus data and control signals. The Model 2040 is available in two versions: The Model 2040 MT-MC lets a V.35 DCE device communicate with a HSSI DTE device. The Model 2040 MC-MT lets a V.35 DTE device communicate with a HSSI DCE device. Both versions are equipped with a male M/34 connector on the converter end, and a male HD-50 on the end of a 6 foot (1.8m) cable (other connector genders and cable lengths are available on a custom basis). Power is supplied to the Model 2040 by an external wall-mount AC transformer.
