Resetting the Parameter Database
The RF-O! transmitter parameter database information is stored on an electrically erasable
programmable read-only memory (EEPROM) on the OCM. Occasionally, new parameters are
added to support a new feature of the RF-O! transmitter software. When new parameters are
added it is sometimes necessary to reset the parameter database.
In certain cases, the user may wish to have certain parameters in the RF-O! transmitter
parameter database set back to default. The use of DIP switch (SW500 on OCB) settings and a
reboot allow the user to selectively reset parameters. There are four different combinations
available to the user, and one special case.
The a 117 command can be used to reset DIP switches remotely. Refer to Appendix D for
additional information.
Table 6-7: DIP Switch Settings
Setting Description
1. No DIP setting (DIP1 and 2 OFF) ALL parameters in the EEPROM are preserved during reboot.
2. DIP2 ON only (DIP1 OFF)
Restores default settings. Protects both Factory Presets and Site Critical
Parameters, such as the user password.
3. Cutover (DIP switches off)
A cutover changes which flash bank becomes active AND emulates a
DIP2-only setting WITH OR WITHOUT the DIP switch itself being active.
This is performed immediately after a software download.
4. DIP1 and DIP 2 ON
Restores default settings to all parameters except Factory Presets (Which
should be the same list of parameters set and stored in the RF-O!
transmitter after the factory calibrates the station). If these parameters are
lost, the station cannot function.
5. EEPROM reset
This option is NOT selectable by the user. If the RF-O! transmitter
software detects a new (blank) EEPROM, a corrupted parameter
database, or a software version prior to 1.1.1, the ENTIRE parameter
database will be set to defaults.
