Here's the difference when you turn on the radio-wide peripheral option
W269 (siren with public address):
-00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
+00000040 00 89 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
-000020c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
+000020c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff 00 |................|
so 0x41-0x42 is related to siren/pa. 0x20ce is a little harder to
interpret, as it's down in the variable position / size area.
When you turn on W269, a new menu entry appears, and is defaulted to:
HILO / AIRHORN SIREN TONES ... YES
MANUAL SIREN TONE ............ WAIL
IGNITION SENSE FOR SIREN ..... YES
SIREN POWERS UP RESET ........ NO
OPTION AUDIO ROUTING ................ YES
IGNITION SENSE FOR PUBLIC ADDRESS ... NO
IGNITION SENSE FOR EXTERNAL RADIO ... NO
DEFAULT P.A. VOLUME LEVEL ........... 11
Changing "hilo / airhorn" to no gives:
+00000040 00 89 2b 00 00 00 00 00 00 00 00 00 00 00 00 00 |..+.............|
so offset 0x42 bit 0x20 is /SIREN-HILO-AIRHORN-SIREN-TONES, as it were.
Changing "manual siren tone" to airhorn gives:
+00000040 00 a1 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x41 bit 0x08 is probably WAIL, and 0x20 is probably airhorn.
Changing "manual siren tone" to yelp gives:
+00000040 00 91 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x41 bit 0x10 is probably YELP.
Changing "ignition sense for siren" gives:
+00000040 00 88 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x41 bit 0x01 is ignition sense for siren.
Changing "siren powers up reset" to yes:
+00000040 00 89 1b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x42 bit 0x10 stores this option.
Changing "option audio routing" to no gives:
+00000040 00 89 4b 00 00 00 00 00 00 00 00 00 00 00 00 00 |..K.............|
so offset 0x42 bit 0x40 is /SIREN-OPTION-AUDIO-ROUTING.
Changing "ignition sense for public address" to yes gives:
+00000040 00 8d 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x41 bit 0x04 enables this sense.
Changing "ignition sense for external radio" to yes gives:
+00000040 00 8b 0b 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x41 bit 0x01 handles this function.
Changing "default pa volume level" to 15 gives:
+00000040 00 89 0f 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
so offset 0x42 bits b3-b0 store this level.
