Identifiers off Any non zero value on or ON will turn Extended Identifiers on 5 Conversion Identifiers The Conversion Identifier only has an effect in User Polled Mode When the module receives this identifier with zero data bits it will sample its inputs This is set as separate command to a data request identifier so that it gives the module time to make a data conversion before having to send the data on the CAN bus 6 Timer The timer value is in milliseconds ms A smaller value means data will be sent more frequently a larger value means data will be sent less frequently The range of values that can be entered is 0 to 65535 however the minimum value that should be entered is 10 Below this value data values may be repeated on successive cycles If a value of 0 is entered the module will change it to 1 on the next power cycle Frequency output can be calculated as follows Freq 1 Timer 1000 The Timer value for a required frequency can be calculated as follows Timer 1 Freq 1000 Some example Timer values are shown against the frequency output Timer Value Frequency 7 Tx Count This TX count is the number of CAN channels transmitted so for the TC8 this should be set to 8 Page 7 30 June 2014 TC8 MANUAL CRACELOGIC Osim Channels In this section each of the eight available channels can be selected from a drop down list When selected the channels specific configuration will be displayed
