Model 15 Field-Programmable Encoder
The Model 15 is designed so that all setup parameters are
keypad programmable and can be changed by a technician
at the site to support any required system changes. The unit
includes the Analog, Digital, and/or Custom Calls paging
format packages. The installer can set up to 14 blocks of
paging formats without having to contact Zetron for new
firmware. This makes the Model 15 a good choice for most
manual encoder applications.
The Model 15 encoder is designed for simple operation. Pages
are entered with the sixteen button keypad and are displayed
on a six character LED display for verification before being
A special key is provided to clear an invalid entry or abort a
page in progress. A page can be repeated simply by pressing
the page key again as long as the last page code is still in the
display. The paging cycle is always indicated in the display to
eliminate confusion.
Stack Pages
An operator can select a programmed stack of pager codes
by entering a single digit. These stacks can be changed in the
Alphanumeric Paging From A Computer
The Model 15 includes an RS-232 port and various cables
are available to connect to a CRT or personal computer. This
allows on-screen control and the entering and sending of
alphanumeric text messages.
Alert Tones
This feature allows the user to send an audible alert
(assuming the use of tone and voice pagers) following each
page or stack of pages in the form of electronic siren, beeps,
or hi/lo warble.
The installation of the Model 15 is straightforward. The
encoders can be powered by a wall transformer or an
external 12 VDC supply. The unit performs a self-test of the
microprocessor circuitry when power is first applied.
With the M15 all connections are made on a screw terminal
strip. Relays allow transmitter keying and microphone muting.
An input is provided for connection to a channel activity
indicator, such as a COR signal, to inhibit the encoder until the
channel is clear. A steady tone can be generated to facilitate
transmitter deviation adjustments.
The Model 15 features analog, digital and custom paging
Analog Formats
The Model 15 allows field selection and programming, from
the front panel keypad, of any of the common analog paging
formats. Formats included are Motorola, GE, Reach, 5/6 Tone,
DTMF, HSC and others.
Digital Formats
The Model 15 includes POCSAG, GOLAY (GSC), Metro
Pageboy, and NEC formats.
Custom Formats
The Model 15 is the ideal encoder for alerting nonstandard
tones, including Plectron and Federal. The Model 15 allows
the installer to program the custom frequencies in the field,
without sending the unit back to Zetron and also lets the
owner create stacks of pages that can be initiated with one or
two keystrokes.
When using this format, a “digital capable” transmitter is
necessary, as with other digital paging formats. Numeric
messages may be entered from the keypad.
Metro Pageboy/ Metrx
This version of the Motorola 2-tone sequential paging tones
and format has a four digit capcode and allows for higher
capacity paging than the more typical codeplans. Group call is
supported in this option as well. SPECIFICATIONS
