IO Warrior Output

I have looked around the site and can't seem to find any specific information about the output capabilities of the I/O Warrior.

Does the device output simply 0 or 5v, or can you output a range of 0-5v, and if so what is the resolution?

Also, the North America distributor does not list the IO Warrior 56 in their product catalog. I am assuming I have to contact them directly to order this?

Thank you for your help in this.

The outputs are digital, not analog. So it is 0 or 1.

Our US sales rep does have the IOW56 in stock, just contact them.

Thank you for the response. I was afraid of that. I have done some searching and it seems there are some inexpensive frequency to voltage chips available (http://www.national.com/mpf/LM/LM2917.html). Can an input be commanded to pulse at a given frequency? If so, what is the range of frequencies supported?[/url]

It would help to know what you want to do, but it sounds like you are trying to take a much too complicated approach.

And no, the IO-Warrior does not have a frequency generator in it. All the available features are listed in the data sheet.

I have a small train set in my basement with 18 sections of track and 15 switches. I want to be able to control each section of track individually as well as switch each switch (3 states, straight, off and turned out) I have also though about using current sensors to determine the position of the locomotive. Also, is each pin capable of sensing an analog signal, or is the input also a 1 or 0?

It seems as though I would need two inputs for each switch and multiple for each section of track (depending on the resolution in train speed I want to achieve.) The track inputs will need to be run through a DAC to produce a voltage. This would mean I would need multiple IO warriors. Can multiple units be used on the same project?

Would this be the best way to proceed?

Thanks.

Again: The list of available features in the IO-Warrior data sheet is complete. There are no A/D or D/A converters in the chip.

To handle any analog signals via IO-Warrior you will need to connect the necessary functions externally. A good option to do so is via IIC or SPI. Either will allow you to connect multiple A/D or D/A converters to the IO-Warrior and there are chips that have multiple channels, so you don't necessarily need to use multiple IO-Warrior chips. Though if a single IO-Warrior is not sufficient you can use multiple IO-Warriors.
