DSP-232+ Dual Switchable Port
DSP Multi-Mode Data Controller

Multimode Data Controller

The plug and play DSP-232 is Timewave’s newest multimode data controller designed around a high-speed, digital signal processor which provides the ultimate in signal filtering, modem performance, and flexibility. Timewave is known for excellent filtering systems. Digital signal processing combined with memory ARQ, true DCD, and hardware HDLC provide the best filtering available. Once you see the features, the upgrade capability, and the affordability, your view of multi-mode controllers will be changed forever.

Power Filtering with DSP

The DSP-232 continues the Timewave tradition of quality signal filtering technology. Incoming signals are digitized by a high speed, analog-to-digital converter. The digitized data is then digitally filtered and analyzed by the on-board digital signal processor. The processed demodulated signals are then passed to a second processor for protocol conversion. The reverse procedure takes place when you transmit. DSP gives the DSP-232 a better shape-factor than analog filters. In addition to the DSP, we’ve included PACTOR memory ARQ for reduced errors. All this makes the DSP-232 the data controller of choice for those who want to connect in poor HF conditions.

Packet Power

Run 9600 or 1200 bps VHF and 300 bps HF packet. This is a true DCD state machine for hearing signals with an open squelch when operating 9600 and 1200 bps packet. Full duplex packet capability lets you speed up communications by sending and receiving simultaneously. KISS mode provides compatibility with the TCP/IP protocol. There are even special GPS capabilities which allow mapping and tracking in packet.

Sound Card Interface

The DSP-232 seamlessly switches between PC-based data programs such as PSK-31 and internal DSP-232 modems such as Pactor. Changing from a sound card modem to a data controller modem doesn’t requir re-wiring of your station! The flexible design permits simultaneous reception and display of signals with a PC program and the DSP-232.  Transformer-isolated audio inputs and outputs use standard stereo audio cables for quick and easy connections.

Connect with the DSP-232

Timewave gives you multiple input and output jacks for optimum connection flexibility. There are separate jacks for each radio I/O, sound card interface, and CW keying.  There is even an extra jack for your sound card speaker!
