Figure 22: Select the ROC Driver
After a new driver is specified, the TPAC reboots and the defaults for the new protocol are
loaded. Modify the default parameters to match the protocol of the end-device. Two unique
parameters for the ROC driver are “Unit” and “ Group”. These define the address the TPAC
uses to identify itself. The ROC response to a poll from the TPAC is addressed to the TPAC
unit address and group number. The unit address and group number both default to 240,
which works for most applications.
