Section 1 Introduction
Ranger ™ Mobile Series
considered a node and therefore has a specific address. This allows the Main Controller
to gather information from all parts of the transmitter and display it on the GUI. One big
advantage of the CAN bus is that it requires only 2 wires of the system control ribbon
cable, eliminating a large amount of discrete wiring which would otherwise be required.
For redundancy, the CAN bus is backed up by parallel, hardwired, control lines that
allow the transmitter to stay on the air even if the CAN bus fails. The parallel control
lines also provide the instantaneous OFF and RF MUTE commands necessary for
transmitter protection.
1.2.2.3 In-System Programming or ISP
The use of the CAN bus for communication between the various Micro Modules in the
transmitter also allows for easy updating of the software used in each transmitter sub-
system via a serial port connection to an external computer. This is referred to as In-
System Programming or ISP.
The real benefit of In-System Programming is that it allows any or all of the transmitter
software to be updated without removing or replacing any firmware ICs. The Harris ISP
program is provided on the CD-ROM accompanying this manual along with all of the
transmitter software as it shipped from the factory. The Harris ISP program is easy to
use and it only takes a few minutes to load or update software.
NOTE:
Software does not need to be loaded into the transmitter unless new components
are installed or an update is sent from Harris. The transmitter, as shipped from the
factory, is preloaded and ready to run.
1.2.2.4 Remote Control
The Ranger™ Mobile Series transmitter has all of the standard parallel remote control,
status and analog metering connections for use with a third party remote control system.
For a complete listing of the remote control connections, see Table 2-1, Table 2-2 and
Table 2-3 at the end of section 2.
1.2.3 PA Module
The Ranger Mobile Series™ PA Module utilizes the same LDMOS amplifier module as
used in the Diamond Series DTV transmitter. Each PA Module will produce up to
400W average power output. A block diagram of the PA module is shown in Figure 1-3.
