UNIVERSAL DIGITAL AND DATA INTERFACE
B-15
Revised May 1998
Part No. 001-9750-006
This tells the radio to enable its internal horn
switch (pulse on for 0.5 second and off for 0.5 second
for 3 cycles). Note that many internal actions can
cancel this operation including many serial
commands. Once sent, no other serial commands
should be sent for three seconds to allow the sequence
to complete.
SOUND_HORN = 0x17
SOUND_RING
This tells the radio to produce a 1 second ringing
tone. Several internal operations can cause this tone to
be distorted since it is produced directly by the micro-
processor, so no serial commands should be sent
during the one second period that this tone sounds.
SOUND_RING = 0x18
TOGGLE_BACKLIGHT
This tells the radio to toggle the backlight. Note
that the current backlight status can be retrieved in the
response to a GET_RADIO_STATUS message.
TOGGLE_BACKLIGHT = 0x21
UI_DISCONNECT
This tells the radio that the external device will
be disconnecting itself from the radio after sending
this message. This command causes all RADIO_
ENABLE_NOTIFY flags to be returned to the power-
on default configuration (all flags set to zero). Any
pending outgoing messages are purged.
UI_DISCONNECT = 0x19
B.8.7 RESPONSE MESSAGES
The following responses must have a Supervision
of <UI_RSP> (0x0D). The first byte of the data field
contains the response subcode. The data field of each
response subcode is shown.
DTMF_DIGITS_SENT
This is a response to a SEND_DTMF_
DIGITS<digits> message, and it informs an external
device that the requested DTMF digits have been sent.
DTMF_DIGITS_SENT = 0x01
GRP_ID
This is a response to a RETURN_GRP_ID
message, and it provides the external device with
information on the requested Group ID data items. If
the radio is scanning when this message is sent, infor-
mation on the revert system and group is returned.
GRP_ID = 0x03
Tx encode ID = Encode ID that was set
Rx decode ID = Decode ID that was set
Home Rptr = Home repeater that was set
LAST_RX_GROUP
This is a response to a RETURN_LAST_RX_
GROUP message.
LAST_RX_GROUP = 0x0A
Rx decode ID = Decode ID of last non-conventional
call received
Home Rptr = Home repeater number of last non-
conventional call received
