System Software
Update
The system software can be updated through the Ethernet or RS-
232 remote interfaces. This operation requires special software
and a passcode provided by Racal. A special function screen,
accessed during power-up of the unit, allows update and
diagnostic functions to be performed. To access this screen,
power on the 1258 and wait for the initial power-on confirmation
beep. After the first beep, press and hold down the '3' key on the
keypad, until an additional beep (or beeps) is heard. Shortly, the
special functions menu will appear. The menu allows software
updates and system verification operations to be performed.
Before updating the system software, Racal will need the current
software version and date information from the About screen
accessed during normal system operation. Racal will then provide
the necessary software, passcode, and instructions to perform the
software update.
