Version Request - CalAmp INTEGRA-TR User Manual

The Frequencies Tab allows the user to program the radio channels (Frequency Pairs).
Rx Frequency
Rx Frequency designates channel receive frequency.
Tx Frequency
Tx Frequency designates channel transmit frequency. There are 6 VHF splinter channels available for quarter-channel VHF
(6.25 kHz) Integras. The frequencies for these splinter channels are:

154.456250 MHz

154.463750 MHz

154.471250 MHz

154.478750 MHz

173.203750 MHz

173.396250 MHz
Caution: If an Integra-TR is programmed on a splinter channel, care must be taken not to perform a Read and a Program
with Field Programming Software Version 2.05 or earlier. Users with splinter frequencies should confirm that they are using
Version 2.06 or later. To download the newest version, visit our website at www.calamp.com.
Tx Power
This field designates the channel pair Power Output Adjust value. The default value is 255 (5 watts). This value should be
left at the default value unless lower power is required to meet regulatory requirements, to increase the allowable transmit
duty cycle or to reduce transmit power. As the output is adjusted downward (less RF output power) the overall current
requirements of the Integra are lessened. When optimizing a system for operational parameters such as RF coverage and
over all power (current) usage, the correct amount of RF power needed for coverage may actually be less than full (5 watts)
output. This in turn can lower overall power (current) needs of the wireless modem.
NOTE: Power does not vary linearly with this parameter so some experimentation may be required to determine the
correct power setting.
