WARNING: Disconnect primary power prior to servicing.
Section 6 ISP (In-System Programming)
Ranger ™ Mobile Series
When firmware in the transmitter is updated, all firmware revisions (for the controllers
and the modules) should be checked and brought up to the revision levels on the CD-
ROM if not already the same. The .s19 file names for the controllers and the modules
have the revision number as part of the name.
For example: RANGER_CTRL_APP_0013.s19 is revision 1.3 Main Controller code.
6.3.1 Control System ISP Procedure
The example given here is for updating the Main Controller board since the steps are
the same for the other control boards except for the update file. This means the
procedure is to be repeated for updating each of the following control boards:
Main Controller
RF Monitor
PA Monitor
External I/O
STEP 1 Insert the CD-ROM into the disk drive.
STEP 2 Open the transmitter controller front door. Connect a standard RS-232
cable from the serial port on your computer to DB9 connector J90 on the
left edge of the Main Controller Board.
STEP 3 Run the “Harris ISP.exe” program. The window shown in Figure 6-2
should open.
STEP 4 Set “Port” to the number of the COM port being used on your computer.
STEP 5 Set “Baud” to 19200.
STEP 6 Press Query Micros; wait for system to recognize the 4 controller boards
as shown in Figure 6-3. If it does not find the micros, press Stop Query,
change the COM port and press Query Micros again.
