4.4.6 WIDE AREA GROUP TRACKING
PROGRAMMING
When Wide Area Group Tracking is enabled with
Multi-Net Auto-Registration (see Section 3.7.2), the
same group remains selected when auto-registration
on another system occurs. This allows a companion
group to be automatically selected in the new system.
For example, the transceiver can be programmed so
that if a telephone group is selected and auto-registra-
tion occurs on a new system, a telephone group is also
selected on the new system. Without wide area group
tracking, the last selected group of the new system is
selected.
With this type of operation, it is important that the
same groups in all systems be programmed. If auto-
registration occurs on a system that does not have the
group programmed (ASN = No), the next higher
programmed group is selected and displayed. The
selected group then changes by one or more which is
probably not the desired operation. This occurs
because all groups that are higher in number are pulled
down to fill the empty position(s). Therefore, the
group also changes when auto-registration occurs on
that system with a group selected that is higher than
the unprogrammed group.
Therefore, when programming wide area group
tracking, observe the following rules:
•
Assign companion groups in sequence starting with
Group 1 and make sure that the same groups are
programmed in each participating system.
•
If groups are programmed that are not companions
with groups in other systems, program them above
the companion range. Then do not leave one of
those groups selected after using it for a call because
if auto-registration occurs, an unexpected group
may be selected.
When the transceiver is programmed, the
programming software does not allow the transceiver
to be programmed if all programmed systems do not
have the same number of programmed groups.
However, it does not check to make sure that the same
groups are programmed in each system.
4.5 PROGRAMMING ONE TRANSCEIVER WITH
ANOTHER (CLONING)
One transceiver can be used to program another
with identical information. One use of this type of
programming may be to reprogram a transceiver in the
field where a computer is not available. Transceivers
of different types cannot be used. For example, do not
use an 800 MHz model to program a 900 MHz model.
Proceed as follows:
a. Turn the power of both transceivers off. Connect
Cloning Cable, Part No. 597-2002-268, between the
microphone connectors of the transceivers.
b. Turn the power of the master (source) transceiver
on. Then turn the power of the slave (destination)
transceiver on.
c. Programming is indicated by “CLONING” in the
alphanumeric display and the rotating scanning
indicators in the status display of both transceivers.
In addition, the system and group number are dis-
played by the master transceiver.
d. When programming is finished, the displays return
to normal.
4.6 WRITE-ON FLASH PROGRAMMING
4.6.1 INTRODUCTION
The E.F. Johnson Write-On
flash programming
feature allows the transceiver operating software
(firmware) to be updated without replacing the micro-
computer or a memory device such as an EPROM.
This reprogramming of the operating software
should not be confused with the programming of oper-
ating parameters described in the preceding sections.
Although both programming procedures use essen-
tially the same programming setup, the software and
procedures are different.
Currently, the Write-On flash programming soft-
ware is available only by downloading it from the E.F.
