PC104-DO48H Users Manual
The PC104-DO48H is a digital output board. The ‘H’ designation indicates that these boards are capable of ‘High Drive’. High Drive TTL is capable of higher currents than standard TTL. A High Drive output is capable of supplying 15 mA and sinking 64 mA. There is no control register to set the port direction from input to output. The PC104-DO48H boards are output only. The PC104-DO48H conforms to the 50-pin connector pin specification of all CIO-DIO family of digital boards, so can be used in place of one another without changing cabling or connectors.
The board is supported by Universal Library programming library.
The board has a variety of switches and jumpers to set before installing the board in your computer. By far the simplest way to configure your board is to use the InstaCal TM program provided as part of your software package. InstaCal TM will show you all available options, how to configure the various switches and jumpers (as applicable) to match your application requirements, and will create a configuration file that your application software (and the Universal Library) will refer to so the software you use will automatically know the exact configuration of the board. Please refer to the Extended Software Installation Manual regarding the installation and operation of InstaCal TM. The following hard copy information is provided as a matter of completeness, and will allow you to set the hardware configuration of the board if you do not have immediate access to InstaCal TM and/or your computer.
