2 more CENTER Operation
2.1 Overview
The PAGE CENTER is a desk top system that provides paging and wireless two-way communications. With
an Intel 32 bit processor at its core, and 4 megabytes of FLASH memory, the PAGE CENTER can handle the
wireless communications needs of the small office or a large plant.
PAGE CENTER features:
a Standalone operation with built-in keypad and LCD display
Build-in RS—232 serial port lb! advanced paging applications.
Built~in telephone interface for remote access.
Internal two-way radio for monitoring the channel and two-way voice communication,
POCSAG paging encoder at 512, 1200, and 2400 baud
999 pager database
Group paging
5 external alarm inputs for automatic generation of pre-programmed pages,
Pages may be initiated from DTMF equipped two-we y radios.
Eluilt-in speaker and microphone, with provisions for external connections.
f,‘
0005501}
The PAGE CENTEI operates in one of two basic modes. They are the Page Mode and the Progrmn Model
The Page Mode is used to send digital pages to a selected pager or group of pagers. It may also be used to
communicate with a two-way radio. Forthe PAGE CENTER to send pages to a pager, it must first be
programmed with the pager‘s CAP code. This is done, one time, using the Program Mode. The Program
Mode is used to set up the individual pagers information, group ini'omration, automatic paging information,
and some system-level features.
Although the operator may send pages using the built—in keypad. pages may also be generated in a variety of
other ways. Pages may be initiated through the RS-232 serial pen on the rear of the unit. Another way is to
use the built-in telephone interface. When connected to a telephone line, pages may be entered using a
touch-tone phone by dialing into the unit. The PAGE CENTER may also be configured to automatically
generate a page, based upon an electrical input to special input pins on the rear of the unit. The PAGE
CENTER is one of the most versatile paging devices on the market today!
The PAGE CENTER has an mtemal database, which stores the CAP code for every pager in your system
The CAP code is the special 7 digit code that identifies an individual pager or paging receiver device, To
make paging simpler, you need only configure the CAP codes once by assigning an easy-to-remember
number or name to it. For instance, you may have 3 pagers with the following CAP codes: 1924589,
00291 1 1, 0935199, You can program them into the database as pager names 1, 2, and 3 as follows:
Pager CAP Code Pager Name
1924589 1
0029111 2
0935199 3
Now, when it comes time to page pager 2, you will only have to enter the digit 2, rather that the whole CAP
code. Other parameters that must be entered into the database for each pager are the pager type (tone,
numeric, alpha-numeric), baud rate (512, 1200, 2400) active or inactive status, and which groups it belongs
to (if any).
To facilitate sending pages to a large number of different pagers, groups of pagers may be set up in the
PAGE CENTEL A group is first assigned a name, and the members of the group are programmed into the
Page 5
Page Center User Manual MNT-PC-UC
group pager database. Once a group is set up, a page may be sent to all the members of the group simply by
sending the page to the named group.
2.2 Keypad
The built-in keypad is used to program the unit, and to manually enter pages. Its 16 keys have the following
functions.
Key Primag Use Secondary Use
0 thm 9 Enter-ingltumbers Selectig a sub-menu
Fl (Enter) Send a page afier it is entered Override monitor, and
transmit immediately.
F2 (Display) Select displjypage function
F3(Voice) (Voice paging not supported at this Talk to a two-way radio
time.)
DEL Correct an incorrect entry
- (Program) Used as a dash (-) when entering a Enters the programming
messgge, mode
H Upd/down arrows scroll through various
options on the display.
VOL+/- Adjust the local speaker volume
The PAGE CENTER has a keypad buffer that allows a user to type faster than the prompts on the display
come up, Keystrokes will not be lost, and eflicient data enuy is possible by operators skilled in the
operation of the PAGE CENTER.
2.3 Display
There is a two-line, twenty-character LCD display on the PAGE CENTER, The three LEDs on the top right
indicate the state of the transmitter, the channel busy, and the programming mode.
2.4 Sending a page
The wuss CENTER is ready to send a page when the LCD display shows:
This means that it is waiting for you to enter the pager name to which you which to send a page to, Using
the keypad, enter the number (not the CAP code) of the pager you wish to page. Once you enter the pager
number, press the F1 key. There are three different types of pagers supponed by the PAGE CENTER. They
are: tone-only, numeric, and alpha-numeric. Depending upon what type of pager you are sending the page
to, one of the following sequences will take place:
a. Tone-only paging
Ifthe pager is a tone-only, it does not have a display, A page sent to it will cause it to beep, When
a page is sent to it, the display will show:
Page 6
Page Center User Manual MNT-PC-UC
While it is sending the page over-the-air to the pager, This will take about one second, afier which
it will display PAGE ACCEPIED for a couple seconds. and then return back to the PAGER N0:
prompt.
b. Numeric and alpha-numeric pagers
If the pager is designated as a Numeric pager or an Alphanumeric pager in the PAGE CENTER
database, then the LCD display will show:
lDllSPAlLY PAGE
for one second, and then the LCD display will show:
TIER MESSAGE ‘
The user enters the message using the keypad into line 2 of the display. If the message is longer
than the length of the display, the display will automatically scroll down to the next line as the
message is entered, Pressing the DEL key allows the operator to delete the last character entered,
Once the data is entered, press the F1 key to send the page. The display will show PAGE
ACCEPTED for a couple seconds along with a bar next to the Transmit indicator, and then the
display will return back to the PAGER N0: prompt,
Typimlly it takes a second or so to send a page to a pager. Ifthe page is intended for a group ofpagers, it
may take longer, A group consisting of 10 pagers may take 5-10 seconds to u-ansmit and a group of 100
pagers may take 50-100 seconds to transmit,
2.5 Group Page
The PAGE CENTER can send a page to a group of pagers through the entry ofa single group name. The
pager numbers that are members of the group must have been previously assigned using the Assign Group
configuration menu. When sending a group page, the PAGE CENTER sequentially sends the page to each
pager in the group,
The procedure for sending a group page is the same as for the individual page described in the above
procedure, Group pages generally take longer to send out, so you may find the PAGE Gem will take a
bit longer to return to the PAGER N0: prompt when a group page is sent.
2.5 Shortcuts
2. 0.1 Function Skip
When you enter the name of the pager to page, the PAGE cram will display the type of page to be sent
(Tone or Display) for one mend. To skip this, use the correct function key instead of the F1 key when
entering the pager name, then the one-second function display will be skipped.
2.6.2 Tone Paging
Some pagers can receive tone or numeric pages, If you wish to send a tone page (make it beep) to a pager
that 15 set-up for numeric or alpha paging, you can press the F4 (Tone) key when entering the page instead
Page 7
Page Conner User Manual MNT-PC-UC
of the F1 (Enter) key, Pressing the F4 key after entering the pager name will force the PAGE CENTER to
send a tone page to the pager.
2.7 Busy Channel Override
The system will normally monitor the channel before transmitting, and if the channel is busy, it will wait to
send the page. While it is waiting you will see the busy LED lit.
v PAGE ACCEPTED “mm“
Busy
, , ,. . .. .. Program
To force the FAQ CENTER to transmit on the unnunna, cm. .. it is busy, press the F1 key (Enter) key when
the Busy channel indicator is on This will force the PAGE CENTER to send the page, even if the channel
is busy. Transmitting on a busy channel may interfere with other radio communications on the channel It
the channel is busy, there is also a chance that the page you send may not be received.
2.8 2~way voice communications
The PAGE CENTER can communicate with portable and mobile two-way radios. The PAGE mama has a
privacy feature called Continuous Tone Coded Squelch System (CTCSS). CTCSS blocks the reception of
signals or noise that are not encoded with certain preset tones, You will only hear signals at the PAGE
CENTER that have the correct CT CSS tone encoded on them. This means that the radio channel may be in
use by someone else, and you W111 not hear anything come out the speaker because the CTCSS decoder has
muted it.
To disable the CT CSS decoder to monitor all of the communications on the channel, momentarily press the
F3 (Voice) key, The display will show LISTENING when the CTCSS decoder is disabled,
Before transmitting, you should always monitor the channel to see if it is busy. When you want to talk on
the channel, press and hold down the F3 (Voice) key If the channel is not in use, the PAGE (INTER will
turn the transmitter on and display TALK on the LCD. Your voice will be sent out over the air, The
microphone is located on the front of the unit, so speak clearly into it in a normal voice. lithe channel is
busy, the LCD will display LrsrrerNa If after 3 seconds you do not release the F3 key. the PAGE
CEN'rus will begin transmitting
Afler you release the F3 key, the display will show LISTENING. If no signal is received within a few
seconds, the display will switch back to PAGER N0: prompt.

Note: When the PAGE CENTER is in the Program Mode, it will revert back to the Page Mode if it is idle (no
keyboard inputs) for more than two minutes.
3.1 Assign Page!
All pagers have an ID code, commonly referred to as a CAP code. It is a long number, difficult to
remember, and may change if a pager is replawd or in for repair. To make paging a pager easy, the PAGE
CENTER uses a database stored in its memory to remember every pagers CAP code. Within the PAGE
CENTER, every pager is assigned a munber. Because pagers don't recognize names, only CAP codes, the
pAoE CENTER must translate the pager number into the proper CAP code, The A - Mign Pager menu is
used for this function.
Begin by entering the Programming Mode as described above, and pressing the number 1 key. The PAGE
PAC-Ell NUMBER _.
DASH (-) m EXIT
Enter the number for the pager you wish to add to the database. For example, to add a pager number "15" to
the database press 1 then 5 then F1, Once a pager name or number is entered the PAGE CENTER will
respond with a prompt asking for the CAP code for this pager. If the pager number was already in the
database, it will display the CAP code already programmed. [fit was not in the database, the CAP code will
default to the pager number. To edit the CAP code, use the DEL key to backspace over it.
After you enter the CAP code for the pager. you must tell the PAGE CENTER just what type of pager is
being assigned The PAGE can!“ will display the default type. Press any of the number keys to cycle

the Program Mode when all of the pagers have been entered into the database.
3.2 Assigning a Group
The Group-Page feature is used to send the same page to a number ofditterent pagers, Gmups have names
just like pagers, and once you define 3 groups and its members, you send pages to the group just as if it were
a single pager. When you assigi a name to a group, it is important that the name is not the same as any
individual pager.
There is a limit to the number of pagers that may be assigned to any one group. This is listed in the
specifications section of the PAGE cerium User Manual.

pressed When any key is pressed, the unit will return to the program mode. Press the » key to return to the
PAGER N0: prompt.
3.4 Alarm Pages
The PAGE CENTER has 3 alarm inputs. These digital inputs are used to generate pre-programmed pages,
each with its own pre-programmed message to any pager, or group of pagers. These may be used for alarms,
but they may also be used to simply generate pie-programmed pages
The inputs should be connected to nonnally-open switches or contacts. When any input is pulled low to
ground, it will generate its pre-prograrnmed page Note that these inputs are not protected from lighting, so
the wires must not be run out of doors. See Section 6.2 for details regarding the wiring of the alarm input
connector.
To set up the alarm pages, the user must perform the following steps:
a) Put the unit into the program mode,
b) Press 4 and then F1 to enter the Alarm sub-menu
c) When the ALARM NuMnEn : prompt is shown, enter the number of the alarm you wish to
configure. Then press the F1 key.
d) The PAGE CENTER will display AlaikM x PAGER on the top line, and the pager number that will
be paged when the alarm is triggered. Erasing the pager name disables the alarm Enter the
munber of the pager you wish to have paged when the selected alarm input is triggered.
e) PAGE CENTER will display ENTER ALARM MSG on the top line of the LCD. On the second
line, you may enter or edit the message to be sent when the alarm is triggered. Press F1 when the
message has been entered.
When entering the alarm message, you may wish to use letters of the alphabet. In this mode, the F1, F2, F3
and F4 keys have slightly different meanings. You can use the numeric keys to enter number, and use the
F2 and F3 keys to scroll through the alphabet to create text. When you have selected a letter that you want.
press the F1 key. Once the message has been entered. press the F4 key. After the message has been
entered, the display will retum to the SET ALARM Nu prompt.
3.5 Accessing the PAGE CENTER via two-way radio.
The PAGE CENTER has a built—in radio transceiver enabling it to receive commands over—the-air to generate
pages, connect to the telephone system, dial phone numbers, remote control a relay, and receive telephone
calls.
To remotely control the PAGE CENTER with a two-way radio, the two-way radio must be equipped with a
DTM]= encoder. All commands sent to the PAGE CENTER are entered into the DTMF keypad, and in most
cases, the commands are similar to the ones used locally on the PAGE CENTFR'S built-in keypad. The two-
way radio operation or” the PAGE CENTER is a standard feature, but it must be enabled before it will work
3.6 Sending Pages from the Two-Way Radio
This section describes how to send a page with the PAGE CENTER using a DTMF keypad-equipped two-
way radio, The PAGE (35mm and the two-way radio must have previously been configured to
communicate on the same channel, and utilize the same CTCSS tones.
To send a page to a pager from the two-way radio, you must
a) Type "‘ 9 to alert the PAGE CENTER that you intend to send a page.
b) If desired, optionally listen to the receiver for the "Enter Pager Number" prompt, which is a
sequence of three tones. A series of alternating high and low tones indicates an error in the
oornmand sequence or a timeout occurred
Page 12
Page Center User Manual MNT-PC-UC
c) Enter the digits of the pager number you wish to page. If the pagers number is less than three
digits in length, then press the * key to terminate the pager‘s number. Note that the 7‘ key is not
used to terminate three digit pager numbers.
d) If desired, optionally listen to the receiver for a low / high tone sequence, which signifies that the
pager number was accepted. A series of alternating high and low tones indicates an error in the
pager number or a timeout occurred.
e) Enter the numeric digits you wish to send to the pager. Do not enter any digits it‘yuu only wish to
"beep" the pager. Note that the following D'l'MF keys which are on many two-way radios with
DTMF keyboards have special meanings:
DTMF Key Pager Character Comments
* - Hyphen character
# (none) Send the page
A Space character
B ] Right bracket
C [ Lefi bracket
D U Urgency indicator
0 Press the # key to send the page.
3.7 Placing Telephone Calls with the TwrrWay Radio
Two-way radios can place telephone calls through the PAnE CENTER to a telephone line connected to the
rear of the PAGE CENTER. The PageCenter also has 10 "auto-dial" telephone numbers which can be
automatically dialed. See the PAGE CENTER Configuration section for information on how to program
these numbers.
The PAGE CENr'ER operates in a simplex mode. In other words, it can only receive or transmit at any one
time, and not both simultaneously. If it is transmitting, it cannot receive, and when it is receiving it is never
transmitting. Because ofthis. there are a number of things to keep in mind when making or receiving a
telephone call through the PAGE CENTER. One is that the two-way radio user will hear an occasional
ticking sound. This is the PAGE CEN11ER verifying that two-way radio is not transmitting The other is that
users must learn to wait about a second before talking whenever the PAGE CENTER switches between
transmit and receive modes.
The PAGE CENTER uses a Voice Operated Switch (VOX) circuit on the telephone line. VOX circuits
switch the PAGE CENTER from transmit mode to receive mode when it detects that the audio coming in
from the telephone line has stopped.
3.7.1 To place a telephone call:
a) Press the * 7 keys on the two-way radio's DTMF keypad. This tells the PAGE CENTER that you
wish to place a telephone call.
in) Listen for the confirmation beeps to come back from the PAGE CENTER.
0) Begin dialing the telephone number you wish to call. At the end of the telephone number, you may
enter a "" to dial the phone number. Altemalively, the phone number will be dialed if no keys are
pressed afier a few seconds. The DTMIF tones being sent to the phone line will be heard to confirm
dialing.

3.7.2
3. 7.3
Once the called party answers, the phone VOX circuit takes over. When the called party speaks,
the PAGE CENTER transmits his or her voice.
A periodic ticking sound will be heard by the mobile user as the PAGE CENTER briefly switches
to receive mode to determine whether the mobile user wishes to interrupt the conversation and has
begun transmitting
If neither party is talkrng, a single beep will be heard periodically to remind the mobile user that the
phone patch is still in operation.
A timeout timer exists in order to shut down the phone patch automatically in the event that the
mobile user goes out of range or has a battery outage. Warning tones will be sent a few seconds
before the timeout timer expires and the phone call is terminated. The mobile user must press * to
reset the timeout timer and continue the phone call.
End the conversation from the two-way radio by pressing the # key. A high, then low tone
sequence should be heard to confirm the disconnect.
To place an AutoDialed call
Press the * 6 keys on the two-way radio's DTNH’ keypad, This tells the PAGE CENTER that you
Wish to make a telephone call to a pro-programmed phone number. Optionally press an auto-dial
number between 0 and 9 , If no auto-dial number is given, then 0 is assumed.
Onoe the called pany answers, the phone VOX circuit takes over, When the called party speaks,
the PAGE CENTER transmits his or her voice.
A periodic ticking sound Will be heard by the mobile user as the PAGE CENTER briefly switches
to receive mode to determine whether the mobile user wishes to interrupt the conversation and has
begun transmitting.
If neither party is talking, a single beep will be heard periodically to remind the mobile user that the
phone patch is still in operation.
A timeout timer exists in order to shut down the phone patch automatically in the event that the
mobile user goes out of range or has a battery outage. Warning tones will be sent a few seconds
before the timeout timer expires and the phone call is terminated. The mobile user must press * to
reset the timeout timer and continue the phone call.
End the conversation from the two-way radio by pressing the W'- key. A high, then low tone
sequence should be heard to confirm the disconnect.

5 more CENTER Serial Port Protocols
__________________________._..__._.__————-—-———————
The PAGE CENTER paging transmitter supports three different serial port communication protocols. Each
protocol has its own uses, and the correct one for one application, may not he the correct one for another.
The PAGE CENTER must be configured to support the desired protocol, and only one protocol may be used
at a time. The three protocols supported are:
TAP (also called 1X0) The Telocator Access Protocol is an industry standard protocol for
communications between paging entry devices and a paging terminal.
Individual pagers can be sent individual messages.
COMPI This protocol is a simple way to send data to one pager, It is designed to allow
a person with a simple computer terminal to type a message into the PAGE
cram. The PAGE CENTER must be pro-configured with the CAPCODE of
the pager to send the data to, and all data sent into the serial port of the PAGE
CENTER Will be sent to that one pager.
COMPZ COMP: is similar to COMP], except each page requires two lines of text to be
entered The first line is the pager number to send the page to, and the second
line is the alpha or numeric message to send to that pager.
5.1 TAP
The Telocator Alphanumeric Protocol, or TAP protocol as it is called, is used to send pages to communicate paging
information to a transmitter. It is a sequence of characters sent over a serial interface to a transmitter. The
transmitter must parse the commands, and take the appmpriate actions
The following sections describe how the TAP protocol works. It assumes that the device communicating to the
PAGE CENTER Station is directly connected to it via a serial table. If other means are used (Le. modem) them the
modem connection must first he established. For the purposes of this manual, the PAGE CENTER is assumed to be
the transmitter, and the device connected to its serial port is the "Entry Device". Typical entry devices are
computers, paging terminals, and alarm monitors. Characters listed in brackets  are ASCII codes, and the
values for them are listed at the end of this document.

ways. One way puts the PAGE CENTER into an Automatic Mode. and the other ways puts it into a Manual

5,2 TAP Protocol Issues
5.2.1 Timing
The PAGE CENTER will only wait for 15 seconds for a response to come back from the Entry Device. If a
response is not received before the timeout period, the PAGE CENTER will cancel the current transaction,
sending the    sequence,
5.2.2 Line Feeds
The PAGE CENTER will ignore all .
XOFF
In the very unlikely event that the user enters more pages than the PAGE CENTER can queue up, the PAGE
CENTER will send the 
character when buffer space is available for more pages. It the PAGE CENTER does not receive data within
10 seconds afler sending an , it will send another .
Page 22
Page Center User Manual WT—PC-UC
5.2.3 EDT
Whenever the PAGE CENTER laminates a session by sending the  sequence, it will drop the
DTR Signal on the RS-232 signal for 250mS. This will normally cause any modern connected to it to
disconnect.
5.3 Sending MultipieLine Pages
If you wish a message to continue on another line of a multi-line pager, you cannot send the  return
into the serial port. Use the TAB character instead of a . The PAGE CENTER will translate it to a
 when it sends the page to the pager.
5.4 Computing the Cheeksum
The checksum is a simple arithmetic sum of the 7-bit values of all characters preceding it The checksum
reported is the least significant 12 bits of this summation, convened to BCD ASCII.
