Connecting the Digital I/O
The DM5806 is designed for direct connection to industry standard opto-22 isolated I/O racks and system
modules. Each digital I/O line on P2 has a digital ground, as shown in Figure 2-1. For all digital I/O connections, the
high side of an external signal source or destination device is connected to the appropriate signal pin on the I/O
connector, and the low side is connected to the DIGITAL GND. A cable to provide direct connection to opto-22
systems, the XO50, is available as an accessory from RTD.
Connecting the Timer/Counter I/O
External connections to the timer/counters on the DM5806 can be made by connecting the high side of the
external device to the appropriate signal pin on on-board connector P6 and the low side to a P6 DIGITAL GND.
Connecting the External Interrupt
The DM5806 can receive an externally generated interrupt signal, EXTINT, through I/O connector P2, pin 2
and route it to an IRQ channel through on-board header connectors P3 and P4. Interrupt generation is enabled
through software. When interrupts are enabled, a rising edge on the EXTINT line will cause the selected IRQ line to
go high, and the IRQ status bit will change from 0 to 1. The pulse applied to the EXTINT pin should have a
duration of at least 100 nanoseconds.
Running the 5806DIAG Diagnostics Program
Now that your board is ready to use, you will want to try it out. An easy-to-use, menu-driven diagnostics
program, 5806DIAG, is included with your example software to help you verify your board’s operation. You can
also use this program to make sure that your current base address setting does not contend with another device.
