The SPice10206 is no longer on sale for new designs. Please contact us if you have an existing design that uses this product.

The SitePlayer Server has eight hardware I/O bits that can be referenced and/or controlled from web pages. Four of these are connected to the SPLat SPice connector on the SPice10206. That means for the very simplest applications, where only up to 4 bits of control are needed, you may be able to get away with not even using the TSP communication interface.

The four bits are designated IO0 through IO3 in SitePlayer. You can find reference to them in the SitePlayer software manual under “Special functions memory map”.These pins are connected to SPice connector pins 6, 7, 8 and 9 respectively. Which I/Os these map to on the SPLat controller depends on the controller. You should refer to the section “SPice connector” within the documentation for your specific SPLat controller, for that mapping. The following table-cum-worksheet should assist. It has been filled in for all applicable controllers at time of writing:

+ Inverted logic

* Doubles as thermistor drive voltage (analog output). If you are using a thermistor on the main board you cannot use this pin on the SPice10206, and you must remove the jumper labeled LK1.

Within the SitePlayer, each bit consists of an output and an input connected to a single pin, very much like SPLat bidirectional I/O points.

Displaying bits on a web page

On the SitePlayer pins IO0 through IO3, if the pin is set to a ‘1’ by the SitePlayer, it can be used as an input to the SitePlayer. In this case the corresponding SPice pin should be configured as an output. With suitable references in your html file, the state of that SPLat output can be displayed on a web page.

Controlling input bits to the SPLat

If a SPice pin is set as an input (to the SPLat), then the SitePlayer can turn that pin on and off in response to a suitably referenced link or other control on a web page. Note that the pins flagged above with a + sign have inverted logic. These are the pins that double up as configuration jumpers on the MMi99 and MMi200 main board (the jumpers must be removed when using SPice boards!). On these pins a 0V input signal is taken as an ON state.
