MODEL 15P FIELD PROGRAMMABLE VS. THE MODEL 15B
The Model 15P is an ideal encoder in most circumstances. The added flexibility of
programmability provides a superior solution to growing or changing paging needs, without
downtime. It can provide an advantage to dealers where an inventory of configurable or
programmable paging encoders enables the quickest possible response to customer requests.
However, the Model 15P is not completely identical to the Model 15B encoder that preceded it.
The following list is provided for those who have experience with the Model 15B in order to
help them decide if the 15P can be used to replace the 15B in their application.
1. As required by a particular installation, Model 15Bs can be preconfigured to provide
automatic Morse code station ID. With this feature, the radio site will send the Morse
Code station identification signal at 15 or 30 minute intervals. The Model 15P can be
programmed in the field to do a Morse Code Station ID, however, the time interval is
fixed at 15 minutes only.
2. Plectron or custom calls are 2-tone pages that use nonstandard tones or reeds and
sometimes nonstandard tone timings. Tone frequencies, timing, and individual
capcodes for the Model 15B must be specified when ordering. These parameters may
be changed only by factory reprogram, not by the user. The Model 15P supports this
kind of paging with a format called CUSTOM TWO TONE, which can hold up to
111 custom pages. The capcode numbers assigned to these pages can be one to four
digits long and are totally independent (i.e.: the programmer in the field is not locked
into any predetermined numbering scheme set by Zetron).
3. Fixed-stack pages available on the Model 15B are a factory programmed group of
capcodes that are sent out as a string of pages with the pressing of a single button.
The Model 15P can also support fixed stack pages, however, there are some
important differences between it and the 15B. The Model 15P supports fixed stack
paging by having a paging format called Custom Stack. This format is assigned a
leading digit in the same way other paging formats are. The individual stacks are
assigned an identifying number when they are entered, and then the capcodes for that
stack are entered. The stack numbers can be from one to four digits in length, so in
order to send a fixed stack page in the Model 15P you enter a leading digit for the
Custom Stack format plus the stack number.
The Model 15P can also support calling a fixed stack page using a single key press.
The Custom Stack format must be assigned to multiple leading digits, and one stack
can be created under each of these leading digits that does not have a number
assigned to it.
