Standalone Considerations
Here’s a list of things to know about standalone operation.
1) When WKUSB is powered up for the first time it loads a default set of standalone
parameters.
2) These parameters can be modified through standalone paddle commands or by hooking
WKUSB up to the Windows application WK3MGR. This is on the CD in the WK3MGR
directory.
3) If the user modifies parameters in standalone mode and wants to preserve them, they
need to remember to save the settings with the standalone
P
command.
4) When WKUSB is connected to the USB port, the PC recognizes the USB device and
registers it but WKUSB remains in standalone mode until an application opens it. The
only serial commands WKUSB will accept while in standalone are ADMIN commands.
5) WK3MGR works by directly reading and writing the EEPROM in the WK3 IC. The
EEPROM contains all of the standalone settings and local messages. Since the
EEPROM is accessed by ADMIN commands, WKUSB can remain in a closed state.
6) When an application opens WKUSB, WKUSB leaves standalone mode and will no longer
responds to the command pushbutton making it impossible to enter paddle commands.
7) After opening WKUSB the host application overwrites the standalone settings with
settings dictated by the host. This must be done to insure settings listed in the host
application’s dialog boxes are in sync with those in WKUSB.
8) You can not run WK3MGR when another application is connected to WKUSB.
9) When the host application closes WKUSB, standalone operation is restored and the
EEPROM settings are reloaded.
