This port is intended for connection to a portable PC. Setpoint files may be created at any location and down-
loaded through this port with the 469PC software. Local interrogation of setpoints and actual values is also
possible. New firmware may also be downloaded to the 469 flash memory through this port. Upgrading of the
relay firmware does not require a hardware EPROM change.
