1-4 5100 ES Series Portable Radio Service Manual
General Information
1.2.4.2
Channels
A channel selects an RF channel or talk group as follows:
Conventional Analog Mode - A channel selects a specific radio channel, Call Guard
(CTCSS/DCS) squelch coding, and other parameters unique to that channel.
Conventional Project 25 Mode - A channel selects a specific radio channel, NAC
squelch coding, talk group ID, and other parameters unique to that channel.
Trunked Project 25 Mode - A channel selects a specific talk group, announcement
group, emergency group, and other parameters unique to that talk group.
SMARTNET/SmartZone and Project 25 Trunked Operation - A channel selects a
specific talk group, announcement group, emergency group, and other parameters
unique to that talk group.
Although it is theoretically possible to program any combination of systems that produces
up to 512 total channels, the maximum number is also limited by the available memory.
For example, since more memory is required to program a SMARTNET system than a
conventional system, the total number of channels decreases as the number of
SMARTNET systems increases. The programming software displays a bar graph which
shows the amount of available memory space that is used by the current data. Refer to
“Transceiver Programming” on page 4-1 for more information.
1.2.4.3
Zones
A zone is a collection of up to 16 channels of any type. For example, a zone could include
12 conventional channels and 4 SMARTNET channels. One use of zones may be to
program the channels used for operation in a specific geographical area. Up to 16 zones
can be programmed with standard models and up to 32 can be programmed if the 512-
channel option is enabled.
1.2.5 Programming
Transceiver programming is performed using a PC-compatible computer, the EFJohnson
5100 Programming Cable, and PC Configure™ programming software (see Table 1.1
“Accessories”).
1.2.6 Alignment
Transceiver alignment is performed using EFJohnson PC Tune™ software and test cable,
and the same computer used for PC Configure™ programming. All adjustments are made
electronically using the software (no manual adjustments are required). For alignment and
performance testing information, refer to the PC Tune manual included on the PC Tune
CD.
