Features:
- A 50 MHz floating-point DSP with a fixed 1 ms watchdog supports direct power-converter control.
- A24/D16 VME master/slave operation and an 8 KB dual-ported SRAM interface connect the processor to the control rack.
- Four daughterboard positions, dual RS-485 paths, and local programmable memory expand communications and I/O beyond the VME datapath.
SW1 performs a hard reset of the processor and every fitted daughterboard. Holding SW2 while pressing and releasing SW1 requests a serial boot from the P6 synchronous port.
The faceplate exposes IMOK and FAIL status indicators, four project-defined amber LEDs, and TP1 through TP4 for digital, analog-output, and common-reference checks.
An add-only electronic ID memory lets the processor read installed board identity and hardware-revision information during power-up without allowing that identity to be altered.
The General Electric DS200DSPCH1A Digital Signal Processor Control Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Processor: A 50 MHz floating-point DSP supplies real-time computation for power-converter control.
- Watchdog: A fixed 1 ms watchdog monitors processor operation.
- Program storage: Program and FPGA configuration data reside on a removable flash-memory SIMM.
- Application storage: A socket-mounted EEPROM retains configurable application items.
- VME role: DS200DSPCH1A operates as an A24/D16 master or slave; slave access uses 8 KB dual-ported SRAM.
- P5 monitor port: A DB15 RS-485 asynchronous port supports an isolated PC connection through external conversion.
- P6 high-speed link: A DB37 synchronous serial port supports DSPC-to-DSPC communication independent of VME.
- UART: The dual-channel device supports up to 1.152 Mbaud with 16-byte transmit and receive FIFOs.
- Daughterboard capacity: Four option positions use paired 60-pin XA and 40-pin XB connectors.
- Position assignment: Positions are interchangeable before project assignment but not after configuration is fixed.
- P2 backplane: Extended paths include tach, diagnostic digital, DAC, differential analog, and application-defined signals.
- P9 expansion: A DIN C96 buffered port carries local data, address, control, and synchronization lines.
- Status indicators: IMOK green reports normal operation, while FAIL red reports a VME-detected failure.
- Project LEDs: Four amber indicators are software-defined for the individual application.
- Testpoints: TP1 checks processor digital I/O, TP2 and TP3 expose ±10 V DAC outputs, and TP4 is analog common.
- Front controls: SW1 performs a hard reset; holding SW2 during SW1 reset requests serial boot from P6.
