North Star has developed the hardware and software for both wired (copper and fiber-optic) and wireless (RF) datalink serial communications interfaces.  Using processors and DSPs which contain on-board UART serial communications ports, we have developed all the necessary hardware to interface these devices to industry standard RS-232 and RS-422 serial communications.  We can engineer a custom interface for your product.  We have also written the software to transmit and receive serial data using these ports for many applications including: 

• 9600, 19200, 38400, and 115200 BAUD RS-232 and RS-422 Serial Communications

• Custom packet definition, sync character, error detection, retransmission schemes, state machines, data parsing

• Motor control, PID, soft stops, run/stop

• VCR control, play, stop, timecode, multi-deck non-linear editing

• TV Camera control, zoom, iris, shutter

• IR Camera control, field-of-view change, non-uniformity correction, gain/level

• Laser Rangefinder control, charge , fire, data reporting

• Serial communications to Windows GUI applications on a PC

• Serial communications to National Instruments' LabView applications on a PC

• 900 MHz and 2.5GHz transceiver interfaces

• Serial port direct memory access (DMA) to processor's memory upon receiving data

• User-programmable interfaces to control systems, read, modify, store parameters

• Serial communications over long distances using fiber-optic transceivers

• LVDS High-speed serial data interfaces

• SPI-bus for control of multiple processors

• I2C-bus for control of multiple processors

• CAN-bus

• Low-voltage PECL

• Synchronous Datalink Communications SDLC protocol, 1Mbps

• Fiber-optic Gyro rate sensors, accelerometers, and inertial measurement units (IMUs)
