In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of the software you received with your CIO-DIO24H and information regarding installation of that software. Please read this booklet completely before installing any software or hardware. -
Page 9: Unpacking The Cio-Dio24H
Quick-Start.pdf. Configuring the CIO-DIO24H The CIO-DIO24H has a bank of base address-select switches, an interrupt level select jumper, and a wait-state jumper. The InstaCal calibration and test program included with the CIO-DIO24H will show you how to configure the board. Run InstaCal to verify or change their settings before installing the board in your computer. -
Page 10: Base Address
CIO-DIO24H. A set of DIP switches is used to set the base address. By placing the switch down, the CIO-DIO24H address decode logic is instructed to respond to that address bit. A complete address is constructed by calculating the HEX or decimal number which corresponds to all the address bits the board has been instructed to respond to. -
Page 11: Interrupt Level
You can set the base address switch to any address in the range of 000-3FC. If you are not using IBM prototyping cards or another board which occupies these addresses, the CIO-DIO24H board's default address of 300h is free to use. -
Page 12: Wait State
Wait state The CIO-DIO24H board has a wait state jumper which you can set to enable an on-board wait state generator (see Figure 4). A wait state is an extra delay injected into the processor's clock via the bus. This delay slows down the processor when the processor addresses the CIO-DIO24H board, so that signals from slow devices (chips) will be accepted. -

Figure 7. C37FFS-x cable Field wiring, signal termination, and conditioning You can use the following cabling, screw termination, and signal condi tioning products with the CIO-DIO24H. – 37-pin screw terminal board. Details on this product are available on our web site at CIO-MINI37 www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=1543. -
Page 15: Functional Details
The voltages and currents associated with external devices range from less than a hundred mA at a few volts for lamps etc., to 50 Amps at 220 volts for electric heaters or other high-load equipment. Attempting to connect such loads directly to the CIO-DIO24H will damage the I/O chip. Heavy loads such as these require external relays. -
