The Tracer-E pc104 card provides 48-lines of 8255 compatible general purpose digital I/O and three 16-bit 8254 compatible counter/timers.

TRACER-E

The Tracer-E is a PC/104 digital I/O board that provides 48-lines of 8255 compatible general purpose digital I/O and three 16-bit 8254 compatible counter/timers. All digital outputs including the counter/timer outputs are high-current. It is designed for use in systems where high reliability is of utmost importance while operating in harsh environments.

High-current digital outputs can sink 64mA and source 18mA over the entire range of operating temperature. This is true even while operating at high temperatures.

8255 Software compatible interface structure provides two 8255 compatible I/O ports that provide 48-lines of general purpose I/O.

8254 Software compatible counter/timers. Three 16-bit counter/timers are based on an 82C54 which can operate up to 40MHz.

Broad selection of interrupt sources that are software selectable.

Direct interfacing to OPTO-22’s isolated I/O racks. Digital I/O connectors are organized to allow direct connection to OPTO-22’s isolated I/O racks including the G4 series, the PB16-H, PB16-J, PB16-K, PB16-L, PB8H and the PB24HQ.

LED Status indicator. Useful in determining general status and in system debugging. A wide variety of signals can be routed to the LED via software selection.

Single +5V Supply Operation means reduced power supply and system level complexities.

FPGA customization available. We are always able to offer FPGA customization to any of our standard products to meet your exact program requirements.

Apex Embedded Systems delivers a higher standard in ruggedized COTs PC/104 products. All products are the result of over three years of testing and customer feedback. All products have been tested to meet or exceed -40 to +85°C operating temperature range. Our PC/104 products are software superset compatible with competitor product, thus offering solutions for existing software (and beyond) as well as a second source option. Need to implement a high speed continuous data logging in windows, but don't want to deal with interrupts? Or, you need interrupts, but interrupt latencies are killing your project? Take a look at the STX104 or STX104-ND data acquisition products which contain a huge one mega-sample buffer. Our ruggedized COTs PC/104 products are in stock and ready to work for you in not only solving your system problem, but ultimately saving you time and eliminating down time. Our products are fully tested and validated from -40 to +85°C with no up-rating of materials. We have had design wins where others have failed. Our PC/104 products are designed specifically for OEMs in medical, military, aerospace, scientific and communications applications where Commercial-Off-The-shelf (COTs) solution is necessary. Need help migrating your old legacy design to new highly integrated PC/104, PCI or CAMAC? We can update and integrated legacy designs quickly while preserving software compatibility where possible.
