1. A Powerful Control Device The firmware on the standard IRIS board has 5 user programmable thresholds When a tilt measurement is taken it is compared to each of these thresholds X tilt X tilt Y tilt Y tilt and tilt in any direction If the measurement exceeds one or more of the thresholds the corresponding output pin s in the H3 connector are set high SV as shown below If the threshold is not exceeded the output remains at 0 Volts The reference angle for the threshold measurement is selected using the autozero command Threshold checking may be turned off with a single firmware command when it is not needed The standard IRIS firmware also allows the user to set the hysteresis of the control thresholds The hysteresis is used as follows After an H3 output pin is set high it APPLIED GEOMECHANICS INCORPORATED is not set low again until the tilt reading has reached a level that is below the threshold by an amount equal to the hysteresis see diagram IRIS includes 3 additional control output pins in the H3 connector bringing the total to 8 The 3 additional pins are not active in the regular versions of the product but may be implemented for your application by custom programming by our engineers Each of the 8 control outputs is separately programmable Another custom option is normally high control output instead of the standard normally low output With normally high controls the voltage2. A TeU A i TaU A B TUU A Tz The BAE output string is not clearly decipherable by HyperTerminal which sometimes hides characters that it has received and cannot understand Because of this it is difficult if not impossible to interpret data in this format The above output string shows four outputs taken from HyperTerminal This encoded output command is typically used to communicate with embedded systems as they can view raw data and perform fast translations The first synchronization byte is 0x55 the second is OxAA The X and Y bytes use 0 0000277 angular degrees per LSB hence the total output range of this output mode is limited to the model D711 2A 4X The temperature uses 0 004 degrees Celsius per LSB The serial number is a two byte integer The checksum byte is the result of ANDing bytes 2 7 with 255 APPLIED APPLIED N B 06 1001 Rev A 5 oe IRIS Tilt Switch and Controller BAE output mode reduces the total number of characters per output to 11 bytes while transferring the same data as the SIM output mode which requires 33 bytes BAE mode also includes checksum and frame synchronization bytes Refer to Appendix A Firmware Commands to decode the output 4 Firmware Commands Valid commands are listed below Some commands have more than one string to trigger the command tt stands for the target ID 99 and ss stands for the source ID 00 Settings stored in nonvolatile memory remain in effect unt
