2.Once the PDI is selected, it will go into Command Mode and allow you to send data commands. The PDI data commands begin with two capital letters designating the specific command and are terminated with a Carriage Return. Most data commands also require a number between the command letters and Carriage Return. This number is typically the desired channel(s) for the data command. If you have a requirement to send the data command to multiple channels simultaneously, you may use one of the following formats as shown for the SA (sample) command:

SA1,2,3,4,5,6,7,8<cr>

Take a single sample for Ports 1-8

SA1-8<cr>

Take a single sample for Ports 1-8

SA/0<cr>

Take a single sample for Ports 1-8

SA1,2,4-8<cr>

Take a single sample for Ports 1, 3, 4, 5, 6, 7,

 

and 8

3.After you have sent the desired data commands to the PDI module, you may disconnect from the PDI by sending $BT<cr>. You may disconnect from the PDI and select a different module or the base unit by sending $BTX<cr>, where X is the desired module number or 0 for the base unit.

IMPORTANT: If the PDI is operating in self reporting mode (i.e., Immediate or Schedule Reporting Method) and a host device issues a data command, the host device must disconnect by sending the Port Select Code and Carriage Return or Line Feed before the PDI will resume sending event samples to the designated host module.

Section 4.3.1 through Section 4.3.10 provide detailed information on the functionality of each data command supported by the PDI. Appendix A provides these same commands in a condensed version for quick reference.
