NOT FOR NEW DESIGNS
SBC Carrier with 3 Module sites and I/O facilities, VME size
The need for 100% fault-tolerant DSP systems has been a dream of Sundance for a long time. The development of the SMT128 provides a platform for 3-way redundancy. If two out of three SMT128s in a turn-key system become damaged, the functionality of the last SMT128 would ensure that the system would continue functioning with no loss of performance. When a faulty SMT128 is being replaced, the ‘live’ SMT128 will simply continue un-interrupted. This is only possible thanks to Sundance’s unique implementation of a distributed and modular DSP concept and the SMT128 can hold three such Modules
Features
- 3-slot Carrier board, VME-sized and fits 6U racks
- On-board DC-DC power supplies convert 24V Input voltages to the 1.5V, 2.5V, 3.3V, 5V & +/-12V required by the Modules
- Three Module sites; One is the Master and interface to the other Modules either via Global Bus access, ComPorts or the Sundance Digital Bus.
- On board QUAD UART, using the OX16C954
- RS232 or RS422 levels
- 2k bytes of EEPROM
- Watch-dog circuits
- On-board 4Mbyte Flash for User programs
- 24x TTL I/O signals
- Four LEDs
Benefits
The flexibility of the SMT128 can best be illustrated by the target application, i.e.. control of bearings in a Power Station and the Modules that has been target for SMT392 and SMT397, but will also work with other DAQ Modules. We have created a system called SMT8024 that describe the working of the system.
