Display > APDA-371 < Utility Commands
This file contains a list of the ASCII commands can be sent to the APDA-371 through the serial port to configure certain
parameters or to perform advanced diagnostics. Most of these commands will not be used by the typical operator
unless instructed by a factory technician. Some of these commands require a password to access. The password is the
same as the F-key sequence used to enter SETUP screens (default password is 1 2 3 4). The appropriate command
character is sent to the APDA to apply the functions shown in the table below.
