between numbers. For example, a five-repeater system
should be numbered 1, 5, 10, 15, and 20. These
numbers are programmed in the repeater and also each
mobile locality (see Section 3.6.8).
If Home Channel Aliasing is used (see Section
2.9.7), the status repeater should be repeater 20 and
repeater 1 should be an active repeater. The other
repeaters should then be spaced evenly from 1-20.
3.11.5 SPECIFYING RIC-EQUIPPED
REPEATERS
When programming the channel numbers of LTR
localities, you specify if the repeater is equipped with
an E.F. Johnson repeater interconnect (RIC) controller.
If a system with a transmit ID code programmed for
interconnect is then selected, the transceiver will
attempt to access only repeaters specified as equipped
with this controller. This allows both interconnect and
non-interconnect repeaters to be programmed in each
locality.
Without this feature, the transceiver may trunk to
a repeater not equipped with an interconnect controller
when a telephone call is made. No dial tone or other
supervision is then returned when the PTT switch is
released which may be confusing to the user.
3.11.6 TEST LOCALITY
Currently, the test locality programmed by Edit >
Locality > Test Locality as described in Section 3.6.8
is not used. The sixteen channels programmed in this
locality are selected by the test mode which is also
currently not available (see Section 2.13).
3.12 UPDATING RADIO SOFTWARE
3.12.1 INTRODUCTION
The transceiver operating software (firmware)
can be updated in the field without replacing the
microcontroller or a memory device such as an
EPROM. For example, the radio software may be
updated to correct software bugs or add feature
enhancements. This is possible because a reprogram-
mable Flash memory device is used for program
storage.
The same basic hardware setup used to program
personality information is also used to update radio
software. One requirement though is that only Remote
Programming Interface (RPI), Part No. 023-9800-000,
can be used. Other RPI's such as the 023-9750-000,
023-5810-000, and 023-5300-000 do not work.
Programming is performed using separate
PCFlash programming software. The program requires
a special data file which contains the updated radio
software (see next section). Refer to Section 5.2 for
more information on loading new operating code.
3.12.2 DATA FILE
To update the radio software, the data file
containing the new radio software is required. The
filename of this data file is 00342xx0.S19. The "xx"
characters indicate the version number of the software.
Contact your Customer Service or your sales
representative concerning the availability of a software
update for this transceiver. It may be available on a CD
with the PCFlash software (see Table 1-1) or on the
®
E.F. Johnson ACES
downloading. To access this system, dial toll-free
1-800-227-3997 (N, 8, 1, ANSI).
If you do not know your login ID or have ques-
tions or would like to sign up for service on this
system, call 1-800-328-3911, extension 7. Once the
data file is obtained, it must be copied to the directory
containing the program.
