cause interference in which case the user must, at his own expense, be required to take whatever measures may
be required to correct the interference.
1.4
Locating the PAGE CENTER
The PAGE CENTER is designed to sit on a desk top. Although this is a good location for ease of operation, it is
usually not the best place to locate the antenna. For most installations, it is recommended that the antenna be
located away from the unit, and high enough to provide good coverage. "Base Station" type antennas will
provide much better coverage than will the "rubber duck" type antennas. This is particularly true if an external
keyboard is to be used, since many keyboards malfunction in the presence of strong RF fields.
The LCD's contrast may be adjusted through a small hole in the rear of the unit. If the LCD is difficult to read
adjust its contrast with a small flat-bladed screwdriver.
1.5
a)

2 Local 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:
Stand-alone operation with built-in keypad and LCD display.
Two built-in RS-232 serial ports for 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
Optional two-tone and group-tone paging
1000 pager database
Group paging
8 external alarm inputs for automatic generation of pre-programmed pages.
Pages may be initiated from DTMF equipped two-way radios.
Built-in speaker and microphone, with provisions for external connections.
May optionally be programmed and operated using an external keyboard
The PAGE CENTER operates in one of two basic modes. They are the Page Mode and the Program Mode. 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. For the 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 pager's information, group information, automatic paging information, and some
system-level features.
Although the operator may send pages using the built-in keypad or an external keyboard, pages may also be
generated in a variety of other ways. Pages may be initiated through the RS-232 serial port 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 internal 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 it an easy-to-remember number. For
instance, you may have 3 pagers with the following CAP codes: 1924589, 0029111, 0935199. You can
program them into the database as pager numbers 1, 2, and 3 as follows:
Pager CAP Code
1924589
0029111
0935199
Pager Number
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).
Page 5
Page Center User Manual
MNT-PC-VB
To facilitate sending pages to a large number of different pagers, groups of pagers may be set up in the PAGE
CENTER. A group is first assigned a number, and the members of the group are programmed into the 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 given group.
2.2
Keypad
The built-in keypad is used to program the unit, and to manually enter pages. Its keys have the following
functions:

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 efficient data entry is possible by operators skilled in the operation of the
PAGE CENTER.
2.3
External Keyboard
An external keyboard with a PS-2 connector may optionally be used if desired. When the external keyboard is
connected, the unit's built-in keypad continues to operate normally. The external keyboard's keys function the
same way as do the unit's keypad in most cases. Additional features are:
•
The alphabetic keys may be used when entering pages to alphanumeric pagers.
•
The ESC key is mapped to the keypad's "-" key.
•
The ENTER key is mapped to the keypad's F1 key.
•
The NUM LOCK key is enabled by default, permitting the operator to use the keyboard's numeric keypad
for more efficient entry of numeric data. Note that the keypad's "." key is mapped to the DEL key.
•
Pressing CTRL and the Windows "MENU" key simultaneously enters the Setup Mode.
IMPORTANT NOTE: Some keyboards are extremely sensitive to the high RF fields present when an antenna
is connected directly to the rear of the PAGE CENTER . The keyboard may stop functioning properly after the
PAGE CENTER transmitter is turned on. If this situation occurs, it is recommended that the antenna be
mounted at least several feet from the PAGE CENTER.
2.4
Display
There is a two-line, twenty-character LCD display on the PAGE CENTER. The three LEDs on the top right side
of the unit indicate the state of the transmitter, whether the channel is busy, and the programming mode.

MNT-PC-VB
Sending a page
The PAGE CENTER is ready to send a page when the LCD display shows:
PAGER NO
This means the PAGE CENTER is waiting for you to enter the pager number to which you which to send a
page. Using the keypad or an external keyboard, 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 standard types of pagers supported
by the PAGE CENTER. They are: tone-only, numeric and alpha-numeric. An option is available which
supports two-tone and group-tone pagers as well. Depending upon what type of pager you are sending the page
to, one of the following sequences will take place:
1. Tone-only pagers
If the pager is a tone-only type, 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 TONE PAGER while it is sending the page over-the-air to
the pager. This will take about one second, after which it will display PAGE ACCEPTED for a couple
seconds, and then return back to the PAGER NO= prompt.
2. 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 NUMERIC PAGER or ALPHA PAGER for one second, and then the
LCD display will show ENTER 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 deletes the previous 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 and then the display will return back to the PAGER NO= prompt.
Only numeric messages may be sent using the built-in keypad. Alphanumeric messages may be sent when
using an external keyboard.
3. Two-tone pagers
Two tone pagers accept a sequence of two tones. The CAPCODE is a number between 0 and 999. A large
number of standard tone plans are supported by the PAGE CENTER. Pagers with non-standard tone
frequencies may be programmed via the database upload command. After the paging tones are sent, either
an alert sound or a voice message from the telephone interface may optionally be sent to the pager.
4. Group-tone pagers
Group tone pagers accept a single tone. The CAPCODE represents the frequency of the desired tone
expressed in units of 1/10 Hz. After the paging tone is sent, either an alert sound or a voice message from
the telephone interface may optionally be sent to the pager.
Typically it takes a second or more to send a page to a pager. If the page is intended for a group of pagers, it
may take longer. A group consisting of 10 pagers may take 5-10 seconds to transmit, and a group of 100 pagers
may take 50-100 seconds to transmit.
2.6
Group Page
The PAGE CENTER can send a page to a group of pager numbers through the entry of a single group number.
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.
Page 7
Page Center User Manual
MNT-PC-VB
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 CENTER will take a bit longer to
return to the PAGER NO= prompt when a group page is sent.
2.7
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
is set-up for numeric or alpha paging, you can press the F4 (Tone) key when entering the page instead of the F1
(Enter) key. Pressing the F4 key after entering the pager number will force the PAGE CENTER to send a tone
page to the pager.
2.8
2-way voice communications
The PAGE CENTER can communicate with portable and mobile two-way radios. The PAGE CENTER 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 low frequency tones. You will only hear signals at the
PAGE CENTER that have the correct CTCSS tone encoded on them. This means that the radio channel may be
in use by someone else, and you will not hear anything come out the speaker because the CTCSS decoder has
muted it.
To disable the CTCSS decoder momentarily in order to monitor all of the communications on the channel, press
the F2 key on the built-in keypad.
To talk on the radio channel, press and hold down the F3 key on the built-in keypad. If the channel is not in
use, the PAGE CENTER will turn the transmitter on and display TALK on the LCD. Your voice will be
transmitted out over the air. The microphone is located on the front of the unit, so speak clearly towards it in a
normal voice.
If the channel is busy with signals which are not being decoded by the CTCSS decoder, the LCD will display
LISTENING and the CTCSS decoder will be disabled in order to monitor the signal being received before
transmitting. If after 3 seconds you do not release the F3 key, the PAGE CENTER will begin transmitting.

3 Two-way Radio and Telephone Operation
The PAGE CENTER has a built-in radio transceiver enabling it to communicate with other two-way radios and
to receive over-the-air commands to generate pages, connect to the telephone system, dial phone numbers and
answer incoming telephone calls. The telephone interface may be utilized for generating pages or initiating
phone patches with two-way-radios.
To remotely control the PAGE CENTER with a two-way radio or from a telephone, the two-way radio or
telephone must be equipped with a DTMF encoder. All commands sent to the PAGE CENTER are entered via
the DTMF keypad, and in most cases, the commands are similar to the ones used locally on the PAGE
CENTER's built-in keypad. The two-way radio operation of the PAGE CENTER is a standard feature, but it
must be enabled before it will work
3.1
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 CENTER 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:
1.
Send * 9 to alert the PAGE CENTER that you intend to send a page.
2.
If desired, optionally listen to the receiver for the "Enter Pager Number" prompt, which is a sequence of
three beeps. A series of alternating high and low beeps indicates an error in the command sequence or a
timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of the
beeps.
3.
Enter the digits of the pager number you wish to page. If the pager's number is less than three digits in
length, then press the * key to terminate the pager's number. Note that the * key is not used to terminate
three digit pager numbers.
4.
If desired, optionally listen to the receiver for a low / high beep sequence, which signifies that the pager
number was accepted. A series of alternating high and low beeps indicates an error in the pager number or
a timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of the
beeps.
5.
Enter the numeric digits you wish to send to the pager. Do not enter any digits if you only wish to "beep"
the pager. Note that the following DTMF keys have special meanings:
DTMF Key
6.
Pager Character
{none}
Comments
Hyphen character
Send the page
Space character
Right bracket
Left bracket
Urgency indicator
Press the # key to send the page.
To send a new message to the same pager again, you may:
1.
Type * 0 to alert the PAGE CENTER that you intend to send a page to the same pager number as before.
2.
Continue from step 4 of the instructions above to input the new message to be sent.

MNT-PC-VB
Placing Telephone Calls from the Two-Way Radio
Two-way radios can place "autopatch" telephone calls through the PAGE CENTER to a telephone line
connected to the rear of the PAGE CENTER.
The PAGE CENTER operates in a simplex mode. In other words, it can only receive or transmit at any given
time, and not both simultaneously. If it is transmitting, it cannot receive, and when it is receiving, it cannot
transmit. Because of this, 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 CENTER periodically checking for transmissions from the two-way radio. 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 circuit switches
the PAGE CENTER from transmit mode to receive mode when it detects that the audio coming in from the
telephone line has stopped.
To place a telephone call:
1.
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.
2.
Listen for the confirmation beeps to come back from the PAGE CENTER. If autopatch operation has
been disabled from the Configuration Menu, then alternating high and low beeps will signal an error. If
voice prompts have been enabled, then a dial tone will be heard instead of the beeps.
3.
Begin dialing the telephone number you wish to call after the dial tone ends. At the end of the telephone
number, you may enter a * to dial the phone number. Alternatively, the phone number will be dialed if no
keys are pressed after a few seconds. The DTMF tones being sent to the phone line will be heard to
confirm dialing.
4.
Once the called party answers, the phone VOX circuit takes over. When the called party speaks, the PAGE
CENTER transmits his or her voice.
5.
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.
6.
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.
7.
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 beeps or a voice message will be sent 30 seconds before
the timeout timer expires and the phone call is terminated. The mobile user may press * in order to reset
the timeout timer and continue the phone call.
8.
3.3
End the conversation from the two-way radio by pressing the # key. A high, then low beep sequence or a
voice message should be heard to confirm the disconnection.
Autodial Calls
The PageCenter has 10 "auto-dial" memories containing telephone numbers which can be automatically dialed.
See the PAGE CENTER Programming section for information on how to program these numbers.
In order to make an Autodial call from a two-way radio:
1.
Press the * 6 keys on the two-way radio's DTMF keypad, followed by the number of Autodial memory
you wish to place the call to. Memory number 0 will be used if no number is sent after the *6 command.
2.
Operation continues from step 4 as described above.

MNT-PC-VB
Receiving Telephone Calls at the Two-Way radio
The PAGE CENTER can also be used to route telephone calls from the telephone line to two-way-radios. To
initiate a phone call from the telephone interface:
1.
Dial the phone number of the telephone line connected to the PAGE CENTER.
2.
The PAGE CENTER will answer the phone in a manner determined by the settings of the "Remote Paging"
and "Call Forwarding" modes as set in the Configuration Menu.

Sending Pages using the Telephone Interface
This section describes how to send a page with the PAGE CENTER using a DTMF keypad-equipped telephone.
Note that the phone will not be answered until any "radio paging" command sequence in progress is completed.
To send a page to a pager from the telephone interface, you must:
1.
Dial the phone number of the telephone line connected to the PAGE CENTER.
2.
If the "Remote Paging" mode has been enabled from the Configuration Menu, the PAGE CENTER will
answer the phone and send an "Enter Pager Number" prompt, which is a sequence of three beeps. If voice
prompts have been enabled, then a voice message will be heard instead of the beeps.
3.
Enter the digits of the pager number you wish to page. If the pager's number is less than three digits in
length, then press the * key to terminate the pager's number. Note that the * key is not used to terminate
three digit pager numbers.
4.
If desired, optionally pause sending beeps and listen for a low / high tone sequence, which signifies that the
pager number was accepted. A series of alternating high and low beeps indicates an error in the pager
number or a timeout occurred. If voice prompts have been enabled, then a voice message will be heard
instead of the beeps.
5.
Enter the numeric digits you wish to send to the pager. Do not enter any digits if you only wish to "beep"
the pager.
6.
Press the # key to send the page. You will hear a series of beeps increasing in pitch or a voice message to
indicate that the page was sent.
7.
After a short delay, the "Enter Pager Number" prompt will be given again. You may send another page if
desired by following the above sequence again.
8.
If the caller hesitates sending DTMF tones for a number of seconds, a series of alternating high and low
beeps or a voice message will be sent, indicating that a timeout occurred. The PAGE CENTER will then
hang-up the phone line.

4.1.1 Serial Port Setup
Each of the two serial ports may be configured independently. The table above lists the parameters which may
be programmed. The serial ports are located at the rear of the unit and are labeled PORT 1 and PORT 2.
Timeout parameters for the various protocols are given in seconds. Set the timeout to 0 if no timeout is desired.
4.1.2 Speaker Enable
If this mode is disabled, then the speaker is muted at all times except in the Diagnostics Mode. This may be
used if the PAGE CENTER is in a location where sounds from the speaker are not desirable.
4.1.3 Busy Channel Lockout
If this mode is enabled, then the PAGE CENTER will not transmit if the channel is busy. This may be desirable
in order to avoid interfering with other users on the channel. This mode should be disabled if there is so much
activity on the channel that the pages are not sent out in a timely manner.
4.1.4 Remote Paging
If this mode is enabled, then remote users are permitted to call the PAGE CENTER via a telephone line and to
generate pages to be transmitted.
4.1.5 Call Forwarding
If this mode is enabled, then remote users are permitted to call the PAGE CENTER via a telephone line and to
request a phone autopatch with two-way-radio users.
4.1.6 Autopatch Timer
The autopatch timer establishes the length of time the PAGE CENTER waits before hanging up the autopatch
automatically. This is needed in case the two-way-radio user's batteries fail or he goes out of range
Enter the number of minutes autopatch may be operated before the disconnect warning tones are sent. The DEL
key may be used to delete digits. Press the "-" key to exit the menu. Note that autopatch operation may be
disabled by setting the Autopatch Timer value to 0.
4.1.7 Voice Prompts
This mode selects whether beeps or voice prompts are used to confirm radio and phone operations with the
PAGE CENTER.
4.1.8 Warmup Signal
If this mode is enabled, then a special "warmup" signal is transmitted for a brief period of time at the beginning
of each page. This is required for more reliable operation by some pagers.
4.1.9 Transceiver Setup
The PAGE CENTER either contains a two-way transceiver or works with an external transceiver. In either
case, the factory has programmed the correct Transmitter Type, Carrier Detect inversion, Transmit Data
inversion and TX Bandwidth modes. The user should not change these settings or improper operation will
result.
Page 15
Page Center User Manual
4.1.10 Transmit and Receive Frequencies
Enter the desired transmit or receive operating frequency using the number keys. The decimal point will
automatically be entered. Use the DEL key to delete any correct entries. Press the F1 or "-" key to accept the
new frequency.
4.1.11 Transmit and Receive Signaling
Carrier Squelch operation may be desirable if there are no other users on the channel and there is no
interference. In this mode, the two-way-radio users will be able to hear the paging signals transmitted by the
PAGE CENTER. To enable this mode, press 1 to select (CARRIER ONLY). Press the "-" key to exit the
menu.
If there are other users sharing the channel, if there is excessive interference, or if the two-way-radio users do
not want to hear the paging signals, then CTCSS operation should be used. In this mode, a low frequency tone
is transmitted along with the desired audio. The receiver will only be enabled if this tone is present at the
correct frequency.
To enable this mode, press 2 to select CTCSS, then use the arrow keys to select the desired tone frequency.
Press the "-" or F1 key to accept the frequency and exit the entry mode.
4.1.12 CW Identification Call Sign
In many cases, the rules and regulations under which the PAGE CENTER is licensed by the government require
that the station's Call Sign be transmitted at regular intervals for identification purposes using Morse Code. The
PAGE CENTER sends the Call Sign (with CTCSS turned off) every 10 minutes if the Call Sign has been
programmed. This feature is disabled when the unit comes from the factory.
To enable this feature, press 5 from the main configuration menu. At the prompt, enter your station's Call Sign
from your license as follows:
•
Numbers are entered directly from the keypad.
•
Letters and other special symbols are entered from the keypad by pressing the arrow keys. Alternatively,
an external keyboard may be used to enter alphanumeric characters directly as typed.
•
Press the F2 key to accept the displayed letter when using the unit's keypad or to enter a "space" character
which is displayed as a "_" and results in a pause in the Morse Code.

The Program Mode is used to program CAP codes, add pagers, delete pagers, assign pagers to groups, configure
the alarm pages, and set up various features of the PAGE CENTER.
To enter the programming mode, press the dash "-" key on the keypad or the ESC key on the external keyboard.
The PAGE CENTER will prompt you to enter the password. After entering the Program Mode password
(7531) and pressing F1, you can select one of the following menu items:
Assign Pager Assigns pager CAP codes
Assign Group Assigns pagers to groups
Test Page
Sends periodic test pages
Alarm Pages
Configures alarm triggered pages
autodial memory Configures Autodial memories
RETURN TO PAGE Return back to the page mode
When you enter the Program Mode you will see the first selections. Use the UP/DOWN arrows to scroll
through the available options. To exit the Program Mode, press the - (Program) key or the ESC key. Any
changes you make will automatically be saved.
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 two minutes, except that test pages may be sent for an unlimited period of time.
5.1
Assign Pager
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 replaced or in for repair. To make paging a pager easy, the PAGE CENTER uses a
database stored in its memory to remember every pager's CAP code. Within the PAGE CENTER, every pager
is assigned a Pager Number. Because pagers only recognize CAP codes, the PAGE CENTER must translate the
pager number into the proper CAP code. The 1 - Assign Pager menu is used for this function.
1.
Begin by entering the Programming Mode as described above, and pressing the number 1 key. The PAGE
CENTER will respond with:
PAGER No =
DASH (-) TO EXIT
2.
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 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. If it 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. Press F1 to enter the new
CAP code.
3.
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 CENTER will display the default type. Press the arrow keys to cycle through
the list of possible pager types. The possible types are: POCSAG 512, POCSAG 1200 and POCSAG 2400.
An option is available which also supports TWO TONE and GROUP TONE pager types. Note that the
OSMAC system must have all pagers set to 512 baud POCSAG. Once the correct paging format type is in
the display, press the F1 key on the keypad or ENTER on the external keyboard.
4.
After programming the type, you must program in the function type of the pager being used. The function
type for POCSAG pagers is one of the following:
•
•
TONE
NUMERIC
(pager just beeps)
(pager beeps and displays numbers)
Page 17
Page Center User Manual
•
ALPHA
(pager beeps and displays numbers and letters.)
The function type for TWO TONE pagers or GROUP TONE pagers is one of the following:
•
•
•
TONE ONLY
(send page tones only)
TONE+ALERT (send an alert sound after the page tones)
TONE+VOICE (permit phone caller to speak to the pager after sending page tones.)
Press the arrow keys to cycle through the list of functions. Press the F1 key when the correct function is
displayed.
5.
If a TWO TONE or GROUP TONE pager has been selected, you will be asked to select the tone plan for
the pager. Use the arrow keys to scroll through the supported plan types. If the tone plan for your pager
isn't listed, then the pager's tone frequencies must be entered using the database upload command.
6.
Once the function has been entered, you are prompted to activate the pager. Press F1 to activate it, or press
an arrow key to switch between Y and N on the display. Press F1 when the correct response has been
chosen.
7.
The PAGE CENTER will ask whether the pager changes should be saved. Press F1 to select Y if you wish
to save the changes. If not, press an arrow key to display N, then press F1.
8.
The PAGE CENTER restart back at the PAGER NO = prompt. It will automatically increment to the
next pager number. Press the - to exit the Program Mode when all of the pagers have been entered into the
database. Your entries into the pager database will then be saved in the internal FLASH memory.
5.2
Assigning a Group
The Group-Page feature is used to send the same page to a number of different pagers. Groups have numbers
just like pagers, and once you define a group and its members, you send pages to the group just as if it were a
single pager. When you assign a number to a group, it is important that the number 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 CENTER User Manual.
1.
To do the group assignments, select 2-Assign GROUP from the program mode menu. The display will
then show:
GROUP NUMBER =
SELECT GROUP
2.
Enter the number of the group you wish to work on and then press the F1 key. Valid group numbers are 1
through 16. The display will then show:
GROUP X PAGER NN
assign pager number
Where X is the group number you wish to work on and NN is the pager number assigned to this group.
Important Note: when you wish to page this group, you will enter the pager number NN for it, not the
group number.
3.
Use the DEL key to backspace over NN if you wish to change the pager number this group is referred to
by. If the pager number NN is already assigned to an active pager, the PageCenter will not allow you to
assign that number to the group and the pager number will be erased. If you wish to use NN for a group
number instead of an individual pager, you must first de-activate the pager. Section 3.1 describes how to
Page 18
Page Center User Manual
deactivate a pager. Once the pager number for this group is set, press the F1 button. The following prompt
will appear.
GROUP X = numeric
SELECT GROUP FUNC
4.
Using the arrow keys, select the function (numeric, alpha or tone) for this pager group. Members of the
group may be of any type, but this selection will determine the prompt to the user when a page to this group
is initiated. Press F1 when your selection is made. The display will change to :
GROUP X
MEMBER NN
ENTER MEMBER NUMBER
5.
X will be the group number you are currently working on, and NN will be a number corresponding to the
member number you wish to edit. The first group member you enter will be member 1. The second one
you enter will be member 2 and so on. The display always first shows the next member number you can
enter a new member as. Use the UP/DOWN arrows if you wish to scroll through the members, or press the
DEL key to edit the member number and manually enter the member number to edit. Press F1 key when
you are ready to edit/add the selected group member. The display will then show:
MEMBER NN =
ENTER PAGER NUMBER
6.
7.
5.3
Enter the number of the pager you wish to add to the group. For example if you wish to add pager number
123 to the group, then enter 1 2 3 and then press the F1 key. Use the DEL key to backspace over any entry
if you wish to edit it. Note that:
•
To see the pagers in the database are members of this group, you can use the UP/DOWN arrow key to
scroll through the members of the group.
•
To delete a member, at the MEMBER NN = prompt, use the DEL key to erase its number from the
screen, and press the F1 key.
To finish entering pagers to this group, press the - key.
Sending Test Pages
The test page mode may be used to check the range of the system. With this mode, the PAGE CENTER will
automatically generate a page to pager number "0" every ten seconds.
1.
2.
Before using this feature, pager number "0" must be programmed as described above.
To enable this feature, enter the program mode and press 3. The display will show:
PAGING pAGEr 0
dash (-) to exit
3.
5.4
Press the - key to return to the programming mode menu.
Alarm Pages
The PAGE CENTER has 8 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 pre-programmed pages.
The inputs may be connected to normally-open switches or contacts. When any input is pulled low to ground, it
will generate a pre-programmed page. When any input is pulled high or allowed to "float high", it will generate
a different pre-programmed page.
Page 19
Page Center User Manual
Alternatively, alarm pages may be initiated from an external keyboard. Hold down the CTRL key and then
press a number key which corresponds to the alarm input number to send the "Alarm Low" message. Hold
down the SHIFT key also to send the "Alarm High" message.
Note that the alarm inputs are not protected from lighting, so the wires must not be run out of doors. See
Section 10.2 for details regarding the wiring of the alarm input connector.
To set up the alarm pages, the user must perform the following steps:
1.

Press 4 to enter the Alarm sub-menu.
When the ALARM NUMBER = prompt is shown, enter the number of the alarm you wish to configure.
Press the F1 key.
The PAGE CENTER will display AlaRM x PAGER on the top line, and the pager number that will be
paged when the alarm is triggered. Erasing the pager number disables the alarm. Enter the number of the
pager you wish to have paged when the selected alarm input is triggered. Press F1 when done.
PAGE CENTER will display ALARM low 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 input goes low. Press F1 when the message has been
entered.
PAGE CENTER will display ALARM hi MSG: on the top line of the LCD. On the second line, you may

7 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 be 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 IXO)
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.
COMP1
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
CENTER. The PAGE CENTER must be pre-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.
COMP2
COMP2 is similar to COMP1, 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.
7.1
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 appropriate 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 cable. If other means are used (i.e. modem) then
the modem connection must first be 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.

DISCONNECT 
 
The Entry Device tells the PAGE CENTER transmitter that it
wants to automatically send a POCSAG page by ending this
sequence.
The PAGE CENTER will respond within one second of the
ACK sequence signifying that the Entry Device has
successfully logged on to the PAGE CENTER. If paging
entries cannot be accepted, it will respond with the NAK
sequence or the ETX sequence, which should force the Entry
Device to disconnect.
This "go ahead" sequence tells the Entry Device that it is OK
to go ahead and send over the information for the first page
or pages. The p is always the lower case "p".
This Pager/Message Sequence Block tells the PAGE
CENTER the ID (the Pager Number in the PAGE CENTER's
database) of the pager this the Message is to be sent to. The
checksum is computes as shown later in this document. The
total number of characters sent from the Entry Device per
sequence should not exceed 255.
When the Entry Device does not want to send any more
pages, it sends this EOT sequence, to tell the PAGE CENTER
that it is finished with this automatic session.
One of these status messages will be returned at the end of
the session. They are for information purposes only.
This is only sent if there was an error in this session,
probably due to an invalid pager ID or a message type
mismatch.

Comment
The Entry Device tells the PAGE CENTER
transmitter that it wants to manually send a
POCSAG page, by ending the M.
The PAGE CENTER will respond within one
second of the M sequence signifying that the
Entry Device has successfully logged on to the
PAGE CENTER, and it is ready to receive
paging info. The PAGE CENTER begins by
responding with this prompt.
The user responds with the ID of the pager he
wishes to page.
The PAGE CENTER responds with one of the
following messages, depending upon the type
of pager that the PagerID is assigned to.
The user enters a message to send to the pager.
The PAGE CENTER displays this message as it
sends the message to the pager.
One of these messages will then be sent from
the PAGE CENTER, depending upon the
current situation with the page that was entered.
The serial port has a 45 second activity time,
and will force and end to the manual session if
the user does not complete the page in that
time.
TAP Protocol Issues
7.2.1 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 time-out period, the PAGE CENTER will cancel the current transaction,
sending the    sequence.
7.2.2 Line Feeds
The PAGE CENTER will ignore all  characters it receives. The Entry Device may send a  with any
.
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 before sending a carriage return. It will send the  character
when buffer space is available for more pages. If the PAGE CENTER does not receive data within 10 seconds
after sending an , it will send another .
Page 25
Page Center User Manual
7.2.3 EOT
Whenever the PAGE CENTER terminates a session by sending the  sequence, it will drop the
DTR signal on the RS-232 signal for 250mS. This will normally cause any modem connected to it to
disconnect.
7.3
Sending Multiple-Line 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.
7.4
Computing the Checksum
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, converted to BCD ASCII.

Restoring/Uploading the Retreived Database
If the database is stored on a disk in the format shown above, it may be re-loaded into the PageCenter. Use a
terminal emulation program to send the ASCII file into either serial port in a plain-text format. The serial port
must be configured for the TAP protocol.
The PageCenter will answer every line sent into it with an OK> if the line was acceptable, or ER> if there was
an error in it. If any errors occur during uploading, a message will be displayed at the end of the upload
sequence and the information received will not be saved. If this occurs, reduce the data rate of the port in use or
enable hardware flow control, then retry the upload operation.
Note that the “DB1[0D]” sequence in the first line tells the PageCenter that a database file is going to be sent
to it. The word “DONE” at the end of the file tells the PageCenter that the file has been sent. Once the word
Page 30
Page Center User Manual
DONE is received by the PageCenter, it will copy the database into its FLASH memory only if no errors were
detected.
8.3.1 Erasing Pagers or Groups from the Database
Uploading the database file to the PageCenter only adds and re-programs the pagers and groups specified. It
does not erase other pagers with entries stored in the unit's memory.
If you want the pager database erased, use a text editor to add a line before the first PAGER entry in the
database. The only characters on the line should be:
ERASEDATABASE[0D]
This will tell the PageCenter to erase whatever is in its database before it adds the new pagers and groups from
the ASCII file. If you only wish to erase the group information, and not the individual pagers, put a line in the
file that reads:
ERASEGROUPS[0D]
8.3.2 Programming Two-Tone Pagers with Non-Standard Frequencies
Two-tone or group-tone pagers using non-standard frequencies and durations may be programmed via the
database upload command. Use a text editor to create an entry in the database file for the pager as follows
before uploading the file to the unit:
PAGER,{0-999},{TYPE},{CAPCODE},{FORMAT},N,{ACTIVE},{DUR-A},{DUR-B},
Where:
PAGER
{0-999}
{TYPE}
{CAPCODE}
{FORMAT}
{ACTIVE}
{DUR-A}
{DUR-B}
Signifies that this line is the data for a pager
Pager number for the pager
Pager type: TONE, ALERT or VOICE
Bits 0 to 15 = First tone's frequency in units of 1/10 Hz
Bits 16 to 31 = Second tone's frequency in units of 1/10 Hz
Paging format: TWO-TONE or GROUP-TONE
Is either Y is the pager is enabled, or N if it is de-activated
Duration of the first tone in units of 50 mS
Duration of the second tone in units of 50 mS. Set to 0 for group-tone pagers.
8.3.3 Programming the Unit's Configuration
The unit configuration data stored in the SERIAL, MODE, RADIO and AUTODIAL entries are normally
ignored when the database file is uploaded to the PageCenter as a security feature in order to prevent
unauthorized users from changing the unit's configuration.
If it is desired to change the PageCenter's configuration with data downloaded previously from a PageCenter
unit, use a text editor to add the following line to the database file immediately after the "DB1" entry:
PASSWORD,xxxxxx,[0D]
Where xxxxxx is the same password required to access the Configuration Mode from the PageCenter's front
panel.
Page 31
Page Center User Manual
9 Firmware Updating
The firmware in the PageCenter can be loaded with firmware updates via the serial port number 1 (lower of the
two serial ports).
Note that you might need to reset the Flash memory and reload the database of pagers after you load the new
firmware into the unit. Before updating the firmware, it is recommended that the pager database be downloaded
and saved as described in the "Retrieving the Pager Database" section of this manual.
Connect a computer’s serial port to the PageCenter, and on the computer, run a terminal emulation program
such as Hyperterminal or ProComm. Set the baud rate to 38.4kbps, 8 data bits, 1 stop bit, no parity.
When powering up the PageCenter, hold the “-” button down. You should see a sign-on message from the
PageCenter that looks like this:
PageCenter software installation utility
Copyright (c) 1999, Sonik Technologies Corp.
San Marcos, CA
Version: 306D1
Erase current software and begin download?
On the computer, press Y for yes if you would like to load new firmware into the unit.
The file name for the PageCenter firmware is 307xxx.BIN, where XX is the revision code.
Begin the file transfer of the new firmware from the computer, using either YMODEM or XMODEM. If one
protocol fails to work, try the other. When the update is complete, the unit will reset and begin operation.
Check to see whether the pager database has been reset by the new firmware version. If it has been, then upload
the pager database previously saved.

10 External Connectors
10.1 External Transceiver
The PAGE CENTER may utilize an internal transceiver, an external transmitter, or an external transceiver. A
15 pin D-sub connector is located on the rear of the PAGE CENTER to facilitate interfacing an external
transmitter or external transceiver to the PAGE CENTER. The pin-out of this connector is as follows:

RX audio input. 1.0V p-p for a signal with full system deviation.
CTCSS tone encoder output.
Do not use and do not connect to anything.
10.2 Serial I/O Ports
The PageCenter has two RS-232 type serial I/O ports on it. The EIA/TIA RS-232, and the equivalent European
CCITT V.28, are electrical standards that cover the signal levels, drive level, and slew rate of compliant
devices. It is important to note that they do not specify baud rates, data formats, or connector pin-outs. These
are set by industry standards and practices.
Equipment using RS-232 ports is grouped into two categories:
DTE Data Terminal Equipment
DCE Data Communications Equipment
(computers, mainframes, terminals)
(modems, printers, etc.)
The PageCenter is wired as a peripheral (DCE) device.
Page 33
Page Center User Manual
The control lines on the serial port are used for controlling the flow of data and the peripheral attached to the
port. The most signals provided for on RS-232 serial interfaces are shown in the following table:
Pin #
Name
TXD
RXD
RTS*
CTS*
DTR*
DCD*
RI*
DSR
GND
Typical RS-232 Serial Signal Functions
Transmit data from the computer to the PageCenter.
Receive Data from the PageCenter to the computer.
Request to send data. This is an output from the computer to the
PageCenter. It indicates to the PageCenter that it is ready to exchange data.
Clear to send. This is a signal from the PageCenter to the computer
indicating that it is OK to send data.
Data Terminal Ready to the PageCenter. This signal indicates to the
peripheral that the host is ready to receive data.
Data Carrier Detect from the PageCenter.
Not implemented.
Data Set Ready from the peripheral. Indicates the peripheral is ready.
System Ground
*The hardware flow control signals, RTS, CTS, DTR, DSR, and DCD are active low. In other words, they are set to binary zero (0) to
assert them and binary one (1) to negate them. Over an RS-232 cable, they are again inverted because RS-232 specification calls for
negative logic. Negating RTS is a binary 1, which is a negative voltage on the RS-232 port.
10.3 Auxiliary/Alarm Connector
A 15 pin D-Sub female connector is located on the rear of the unit. This connector has digital inputs used for
triggering alarms. It also has contacts for two relay outputs. The digital inputs may be programmed to
automatically generate a page or dial the phone. The relay outputs may be switched on remotely via the
telephone, radio, or console.
Note that all digital alarm inputs have an internal 10K pull-up resistors connected. Alarms are activated by
pulling the input to ground. Open circuit or a TTL/CMOS high level is the inactive state. Do not pull these
inputs above 5V.

12.2 Test Procedure
12.2.1 General Setup
1. Apply DC power to the unit. Connect the service monitor to the ANT port.
2.
Download the Flash code to the unit if it is not already programmed. Hold down the "-" key while
powering up the unit to enter Flash code programming mode. See the section on "Firmware Updating" for
additional information.
3.
Adjust the LCD contrast control on the rear panel of the unit.
12.2.2 Radio Interface
This procedure assumes a properly tuned transceiver is installed in the unit. You will need a DC power source,
service monitor, oscilloscope, and DVM. Full System Deviation =5.0 kHz for wide-band versions, and
FSD=2.5 kHz for narrow-band versions. Depending upon the type bandwidth of the transceiver used, you will
have to make slightly different adjustments.
1.
Program the unit’s transmit and receive frequencies. Disable sub-audible signaling.
2.
Set the TX bandwidth to “wide band” or "narrow band" depending on the bandwidth of the transceiver unit
installed.
3.
Generate an RF carrier on the receive frequency, 1 kHz tone, 60% FSD = 3 kHz / 1.5 kHz. RF level 10 uV.
4.
Adjust R16 for a 1.5 V p-p (530 mV RMS) signal on TP8.
5.
Adjust the RF generator to .35 uV. Adjust R9 so that the carrier detect LED is on, and so that it goes off
when the RF level is below .25 uV.
6.
Set the speaker volume level to normal level (about 25% full volume).
7.
Set the service monitor to measure the transmitter's FM deviation. Key the transmitter using the F3 key.
8.
Adjust R160 so the carrier is on frequency.
9.
Blow into the microphone strongly and adjust R41 (limiter) for 4.5 kHz / 2.25 kHz maximum deviation.
10. Adjust R60 (mic gain) for 3 kHz / 1.5 kHz deviation when speaking into the mic with a normal voice level
from a distance of about 1 foot away.

Page Center User Manual
11. Send a 1200 bps test signal to the transmitter using Test Function 1. Adjust R34 for 4.0 kHz / 2 kHz (0 to
peak) deviation.
12. Unkey the unit.
13. Enable a 100 Hz CTCSS encoder on the transmit frequency.
14. Key the transmitter with the F3 key. Adjust R32 for +/-500 Hz deviation of the CTCSS tone.
15. Measure the transmitter's power level to verify that it is set to the desired level with the internal jumpers.
12.2.3 Telco Interface
1. Generate an RF carrier on the receive frequency, 1 kHz tone, 60% FSD = 3 kHz / 1.5 kHz. RF level 10 uV.
2.
Connect the TELCO line to the RX audio by holding the 2 button down on power up to bring-up the test
mode, then press F1 and F2.
3.
Adjust R69 (telco line level) for a level of –9 dBm on the line.
4.
Disable the RX audio by pressing F2 twice more. Generate a DTMF tone from the PageCenter by pressing
3 and then F4.
5.
Verify that the line level is between -15 and -12 dBm. Then press the DOWN arrow to turn off the DTMF.
6.
Generate a –9 dBm 1000 Hz tone onto the TELCO line from an external test instrument. Alternatively,
press a key on a telephone connected to the phone interface.
7.
Connect the TELCO to the transmitter by pressing F2 twice.
8.
Measure the p-p waveform at TP10 on an oscilloscope. Adjust R52 so that the audio signal is just below
the clipping level.
12.2.4 Final Test
