The Data Connect ( formerly Telenetics ) FlashPoll DSP9612 is a triple mode, full-featured 9600 QAM Fast Poll, ITU V.23 and Bell 202T leased line or private wire modem with the fastest training time in the industry: 23msec RTS/CTS delay at 9600 bps and 8 ms in Bell 202T Mode.

Ideal for utility and industrial automation multi-dropping applications, including SCADA systems, traffic automation and oil or gas automation projects, where an unlimited number of drops is desirable at ranges up to 16 miles (26 Km). The DSP9612 is a modem designed for 4-wire, full-duplex or 2-wire, half-duplex operation over a voice-band leased line or private copper wire. The modem design utilizes the latest digital-signal processing (DSP) technology to achieve high performance with an adaptive equalizer for the best operation on the poor unconditioned lines.

In FlashPoll Mode (9600/4800 bps), the DSP9612 employs Data Connect ( formerly Telenetics )’ proprietary modulation and encoding scheme to achieve fast modem training time. In V.23 or Bell 202T Mode, the modem is also backward compatible with V.23 (0 – 1200) or Bell 202T (0 – 1800 bps) modems. Ideal for systems where fast response, short training time and low throughput delay is required, the FlashPoll is optimized for fast receiver equalizer training and extremely low throughput delay.

The triple mode capability allows the DSP9612 to communicate with existing V.23 or Bell 202T remote modems at up to 1800 bps, which can then be upgraded at a later date to Data Connect ( formerly Telenetics ) DSP9612 FlashPoll standalone modems and switched to 9600 bps.

Three models are available: Rack Mount (RM) for insertion into a RM16 nest, Standalone AC/DC powered (FP) and Standalone low voltage DC powered (LV). Auto RTS is a new feature allowing multidrop for devices with 3 wire data interfaces and no control signals (no RTS signal) required.
