This reads from programmable range and the channel spacing of the connected radio
e.g. F3 458 – 4760MHz 12.5KHz
TX F3 458 – 470MHz RX F2 430 – 442MHz 12.5KHz
6.8.5 CHANNEL
SELECTION
MODE
There are two ways of setting up channels on the radio, in INCREMENTAL mode a start
frequency for both RX and TX is set up along with a channel increment and the desired
number of channels, for example entering 450MHz as the RX and TX start frequency, 5 as the
number of channels, and 12.5kHz as the channel increment, will result in frequencies of
450.0000, 450.0125, 450.0250, 450.0375, and 450.0500 being allocated to channels 1 to 5 of the
modem, the TX and RX frequencies can be offset by using different start frequencies. Up to 80
channels can be programmed in this way. (Note that selection of MPT1329 or MPT1411 for
frequency range forces use of incremental mode and inhibits alteration of the number of
channels or their spacing). In DISCRETE mode channel frequencies may be explicitly entered
in the channel data and do not have to conform to any regular spacing.
6.8.5.1
Number of Channels
This option sets the number of channels required in INCREMENTAL channel selection mode,
it is suppressed when the mode is set to DISCRETE. See the section on CHANNEL
SELECTION MODE for more detail.
6.8.5.2 Channel
Increments
This option sets the channel spacing required in INCREMENTAL channel selection mode, it
is suppressed when the mode is set to DISCRETE. See the section on CHANNEL .
6.8.5.3
RX Start Frequency
This option sets the channel one RX frequency required in INCREMENTAL channel selection
mode, all subsequent channels are spaced above this frequency separated by the CHANNEL
INCREMENT, it is suppressed when the mode is set to DISCRETE. See the section on
CHANNEL SELECTION MODE for more detail.
6.8.5.4
TX Start Frequency
This option sets the channel one TX frequency required in INCREMENTAL channel selection
mode, all subsequent channels are spaced above this frequency separated by the CHANNEL
INCREMENT, it is suppressed when the mode is set to DISCRETE. See the section on
CHANNEL SELECTION MODE for more detail.
6.86 POWER
RANGE
This option is used to select either the 10mW - 1Watt or 50mW - 5Watt transmitter version.
6.8.7
TX POWER
The required transmitter power in watts can be entered in this field.
Fore example 1.32Watts or 0.05 Watts.
6.8.8
POWER SAVE OPTIONS
The save on, save off and resume time are all programmable parameters to provide further
power saving features.
6.8.8.1
Save On Time
This is for power save programming and sets the time the transceiver is switched off for
during the power save cycle (Power Save On). The Save On Time is programmable from
0 - 1500ms in 50ms steps. A setting of 0 disables power save.
