DIAL
The DIAL command allows access to the full conventional mode dialling
capability of the radio. Selcall and DTMF sequences can be dialled on the
current channel. An TM8200 trunked radio must change to a conventional
channel using a function key before executing this command. The function
key is set to “Switch Mode” in the MPT Key Settings form of the TM8200
programming application.
Format
d [SIZE] [DTYPE] [NUMBER_STR] [CHECKSUM]
■
‘d’ is sent as a single ASCII character and represents the DIAL command.
■
[DTYPE] is a single ASCII character representing the type of dialling
required.
■
[NUMBER_STR] represents the dialled sequence. The range of allowed
characters depends upon the value of [DTYPE].
Note
The DIAL command initiates the calling process only. The call
may take some time to get through, especially if the channel is
busy or the system heavily loaded. The receiver will return a
prompt as soon as the DIAL command is accepted, but the PC
may have to wait for a PROGRESS message advising successful
call set-up before proceeding.
Examples
d0601234507
a command to initiate Selcall dialling of the number
1 2 3 4 5.
d0611234506
a command to initiate DTMF dialling of the number
1 2 3 4 5.
1.9.3
FUNCTION
The FUNCTION command provides access to various hardware and
miscellaneous functions.
Format
f [SIZE] [FUNCTION] [SUBFUNCTION] [QUALIFIER]
[CHECKSUM]
[DTYPE] [NUMBER_STR]
0
(Selcall)
0...9, A...F, -, V (maximum of 32 digits).
Selcall strings usually use the digits 0 to 9 as some of the tones A to
F have special meaning, e.g. A = Group; C = Reset; E = Repeat.
Selcall calls are made within the bounds of the following
parameters, as programmed into the radio: tone period, tone set
and Lead-In Delay, etc.
1
(DTMF
conventional)
0...9, A...D, *, #,-(maximum of 32 digits)
DTMF calls are made within the bounds of the following
parameters, as programmed into the radio, e.g. key-up delay, tone
period and inter-tone gap.
