Blind Dial Mode
If the PRU+ has made three (3) attempts where a “No Dialtone” has been indicated, the PRU+ will
automatically default into blind dial mode. This will enable the PRU+ to attempt to connect to the
Central Computer even if the dial tone used by the local phone company is non-standard and cannot
be detected through normal hardware detection. The PRU+ will remain in blind dial mode until the
PRU+ has been turned off or reset.
