CANbus-TD-TDM-OM-E RevB

 To Frame ID - When using an in range or out of range ID Condition (previous), specify a To

Frame ID value for triggering.

6. Data Pattern Setup

Fields on this section of the dialog are only enabled when using the Data trigger type.

 Data Condition - The Data Condition can be set to many different values. The Data

condition can be set to <=, <, =, >, >=, not =, in a range, out of a range, or don’t care.

 DLC - The DLC (data length code) can be set to any integer value from 0 to 8. It should

match the DLC of the CAN message you want to trigger on. If you set it to a value less

than 0, it will default to 0. If you set it to a value greater than 8, it will default to 8.

 Byte Order - Choose from either Motorola (default) or Intel byte orders.

 Start Bit and # Data Bits - The CANbus trigger allows you to trigger on up to 64

contiguous data bits (8 data bytes). This maximum 64-bit string can start at any location

in the CAN message data field - it is not limited to the start of a full byte or a nibble.

The Start Bit can be any value from 0 to 63. If you enter a value less than 0, it will default

to 0. If you enter a value more than 63, it will default to 63. The Start Bit value is always in

LSB format (i.e., the bit number as shown on the decoded waveform, with bit 0 being at

the far left and bit 63 being at the far right of the data string). Remember that the 1st

data byte is bits 0-7, the 2nd data byte is bits 8-15, etc. Also, make sure that your Start Bit

value makes sense in relation to the DLC Value. For instance, a Start Bit value of 32 with a

DLC Value of 4 is not going to result in a successful trigger.

The # Bits can be any value from 1 to 64. If you enter a value less than 1, it will default to

1. If you enter a value more than 64, it will default to 64.

 Sign Type - Choose between signed and unsigned integer format.

 Data Value and Data Value To - The Data Value is set in Binary or Hexadecimal format.

For Hexadecimal, if desired, you can precede the ID value with “0x”, but this is not

necessary. Be sure to enter a Data Value that matches the DLC Value.
