Internal circuitry may not be modified.Modification of circuitry within this unit may void your authority to operate the equipment.1.3 Radio Communication InterferenceThe PAGE CENTER generates and uses high-frequency radio energy which can cause interference if notinstalled in accordance to the user manual and using sound radio system engineering practice. For best results,it is recommended that a qualified radio service technician install and configure the PAGE CENTER.The PAGE CENTER has been tested and found to comply with the limits for a Class A computing devicepursuant to Part 15 of the FCC Rules and Regulations. Operation of this device in a residential area is likely tocause interference in which case the user must, at his own expense, be required to take whatever measures maybe required to correct the interference.1.4 Locating the PAGE CENTERThe PAGE CENTER is designed to sit on a desk top. Although this is a good location for ease of operation, it isusually not the best place to locate the antenna. For most installations, it is recommended that the antenna belocated away from the unit, and high enough to provide good coverage. "Base Station" type antennas willprovide much better coverage than will the "rubber duck" type antennas. This is particularly true if an externalkeyboard 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 readadjust its contrast with a small flat-bladed screwdriver.1.5 Unit Setupa) Connect the antenna or antenna cable to the BNC jack on the rear of the unit.b) If you are using the PAGE CENTER with a computer system, connect the computer's RS-232 port to thelower serial port on the rear of the unit.c) If you are using an external keyboard, connect it to the PS-2 keyboard jack at the rear of the unit.d) If the telephone interface will be used, connect a telephone line to the RJ-11 jack on the rear of the unit.e) Connect the DC power supply to the PAGE CENTER. It connects to the large DIN connector on the rear.Plug the external DC supply into an AC wall socket. Turn the power to the unit ON.f) Configure the unit if necessary using the Configuration Mode.
Page Center User Manual MNT-PC-VBPage 52 Local Operation2.1 OverviewThe PAGE CENTER is a desk top system that provides paging and wireless two-way communications. With anIntel 32 bit processor at its core, and 4 megabytes of FLASH memory, the PAGE CENTER can handle thewireless 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 keyboardThe PAGE CENTER operates in one of two basic modes. They are the Page Mode and the Program Mode. ThePage Mode is used to send digital pages to a selected pager or group of pagers. It may also be used tocommunicate with a two-way radio. For the PAGE CENTER to send pages to a pager, it must first beprogrammed with the pager's CAP code. This is done, one time, using the Program Mode. The Program Modeis used to set up the individual pager's information, group information, automatic paging information, and somesystem-level features.Although the operator may send pages using the built-in keypad or an external keyboard, pages may also begenerated in a variety of other ways. Pages may be initiated through the RS-232 serial port on the rear of theunit. Another way is to use the built-in telephone interface. When connected to a telephone line, pages may beentered using a touch-tone phone by dialing into the unit. The PAGE CENTER may also be configured toautomatically generate a page, based upon an electrical input to special input pins on the rear of the unit. ThePAGE 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. TheCAP code is the special 7 digit code that identifies an individual pager or paging receiver device. To makepaging simpler, you need only configure the CAP codes once by assigning it an easy-to-remember number. Forinstance, you may have 3 pagers with the following CAP codes: 1924589, 0029111, 0935199. You canprogram them into the database as pager numbers 1, 2, and 3 as follows:Pager CAP Code Pager Number1924589 10029111 20935199 3Now, when it comes time to page pager 2, you will only have to enter the digit 2, rather that the whole CAPcode. 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 Center User Manual MNT-PC-VBPage 6To facilitate sending pages to a large number of different pagers, groups of pagers may be set up in the PAGECENTER. A group is first assigned a number, and the members of the group are programmed into the grouppager database. Once a group is set up, a page may be sent to all the members of the group simply by sendingthe page to the given group.2.2 KeypadThe built-in keypad is used to program the unit, and to manually enter pages. Its keys have the followingfunctions:Key Primary Use Secondary Use0 thru 9 Entering numbers Selecting a sub-menuF1 Send a page after it is entered Select options from thesub-menusF2 Monitor the channelF3 Talk to a two-way radio Monitor the channel if itis busyF4 Send a tone-only page to a numeric oralphanumeric pagerDEL Correct an incorrect entry- (Program) Used as a dash (-) when entering amessage. Enters the programmingmode and exits menus↓↑ Up/down arrows scroll through variousoptions on the display.VOL+/- Adjust the local speaker volumeThe PAGE CENTER has a keypad buffer that allows a user to type faster than the prompts on the display comeup. Keystrokes will not be lost, and efficient data entry is possible by operators skilled in the operation of thePAGE CENTER.2.3 External KeyboardAn external keyboard with a PS-2 connector may optionally be used if desired. When the external keyboard isconnected, the unit's built-in keypad continues to operate normally. The external keyboard's keys function thesame 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 keypadfor 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 antennais connected directly to the rear of the PAGE CENTER . The keyboard may stop functioning properly after thePAGE CENTER transmitter is turned on. If this situation occurs, it is recommended that the antenna bemounted at least several feet from the PAGE CENTER.2.4 DisplayThere is a two-line, twenty-character LCD display on the PAGE CENTER. The three LEDs on the top right sideof the unit indicate the state of the transmitter, whether the channel is busy, and the programming mode.
Page Center User Manual MNT-PC-VBPage 72.5 Sending a pageThe PAGE CENTER is ready to send a page when the LCD display shows:This means the PAGE CENTER is waiting for you to enter the pager number to which you which to send apage. Using the keypad or an external keyboard, enter the number (not the CAP code) of the pager you wish topage. Once you enter the pager number, press the F1 key. There are three standard types of pagers supportedby the PAGE CENTER. They are: tone-only, numeric and alpha-numeric. An option is available whichsupports two-tone and group-tone pagers as well. Depending upon what type of pager you are sending the pageto, one of the following sequences will take place:1. Tone-only pagersIf 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 tothe pager. This will take about one second, after which it will display PAGE ACCEPTED for a coupleseconds, and then return back to the PAGER NO= prompt.2. Numeric and alpha-numeric pagersIf 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 theLCD display will show ENTER MESSAGE. The user enters the message using the keypad into line 2 ofthe display. If the message is longer than the length of the display, the display will automatically scrolldown to the next line as the message is entered. Pressing the DEL key deletes the previous characterentered. Once the data is entered, press the F1 key to send the page. The display will show PAGEACCEPTED 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 whenusing an external keyboard.3. Two-tone pagersTwo tone pagers accept a sequence of two tones. The CAPCODE is a number between 0 and 999. A largenumber of standard tone plans are supported by the PAGE CENTER. Pagers with non-standard tonefrequencies may be programmed via the database upload command. After the paging tones are sent, eitheran alert sound or a voice message from the telephone interface may optionally be sent to the pager.4. Group-tone pagersGroup tone pagers accept a single tone. The CAPCODE represents the frequency of the desired toneexpressed in units of 1/10 Hz. After the paging tone is sent, either an alert sound or a voice message fromthe 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, itmay take longer. A group consisting of 10 pagers may take 5-10 seconds to transmit, and a group of 100 pagersmay take 50-100 seconds to transmit.2.6 Group PageThe 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 Groupconfiguration menu. When sending a group page, the PAGE CENTER sequentially sends the page to eachpager in the group.PAGER NO =
Page Center User Manual MNT-PC-VBPage 8The 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 toreturn to the PAGER NO= prompt when a group page is sent.2.7 Tone PagingSome pagers can receive tone or numeric pages. If you wish to send a tone page (make it beep) to a pager thatis 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 tonepage to the pager.2.8 2-way voice communicationsThe PAGE CENTER can communicate with portable and mobile two-way radios. The PAGE CENTER has aprivacy feature called Continuous Tone Coded Squelch System (CTCSS). CTCSS blocks the reception ofsignals or noise that are not encoded with certain preset low frequency tones. You will only hear signals at thePAGE CENTER that have the correct CTCSS tone encoded on them. This means that the radio channel may bein use by someone else, and you will not hear anything come out the speaker because the CTCSS decoder hasmuted it.To disable the CTCSS decoder momentarily in order to monitor all of the communications on the channel, pressthe 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 inuse, the PAGE CENTER will turn the transmitter on and display TALK on the LCD. Your voice will betransmitted out over the air. The microphone is located on the front of the unit, so speak clearly towards it in anormal voice.If the channel is busy with signals which are not being decoded by the CTCSS decoder, the LCD will displayLISTENING and the CTCSS decoder will be disabled in order to monitor the signal being received beforetransmitting. If after 3 seconds you do not release the F3 key, the PAGE CENTER will begin transmitting.
Page Center User Manual MNT-PC-VBPage 93 Two-way Radio and Telephone OperationThe PAGE CENTER has a built-in radio transceiver enabling it to communicate with other two-way radios andto receive over-the-air commands to generate pages, connect to the telephone system, dial phone numbers andanswer incoming telephone calls. The telephone interface may be utilized for generating pages or initiatingphone patches with two-way-radios.To remotely control the PAGE CENTER with a two-way radio or from a telephone, the two-way radio ortelephone must be equipped with a DTMF encoder. All commands sent to the PAGE CENTER are entered viathe DTMF keypad, and in most cases, the commands are similar to the ones used locally on the PAGECENTER's built-in keypad. The two-way radio operation of the PAGE CENTER is a standard feature, but itmust be enabled before it will work3.1 Sending Pages from the Two-Way RadioThis section describes how to send a page with the PAGE CENTER using a DTMF keypad-equipped two-wayradio. The PAGE CENTER and the two-way radio must have previously been configured to communicate onthe 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 ofthree beeps. A series of alternating high and low beeps indicates an error in the command sequence or atimeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of thebeeps.3. Enter the digits of the pager number you wish to page. If the pager's number is less than three digits inlength, then press the *key to terminate the pager's number. Note that the *key is not used to terminatethree digit pager numbers.4. If desired, optionally listen to the receiver for a low / high beep sequence, which signifies that the pagernumber was accepted. A series of alternating high and low beeps indicates an error in the pager number ora timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of thebeeps.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 Pager Character Comments* - Hyphen character# {none} Send the pageA Space characterB ] Right bracketC [ Left bracketD U Urgency indicator6. 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.
Page Center User Manual MNT-PC-VBPage 103.2 Placing Telephone Calls from the Two-Way RadioTwo-way radios can place "autopatch" telephone calls through the PAGE CENTER to a telephone lineconnected 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 giventime, and not both simultaneously. If it is transmitting, it cannot receive, and when it is receiving, it cannottransmit. Because of this, there are a number of things to keep in mind when making or receiving a telephonecall 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 thatusers must learn to wait about a second before talking whenever the PAGE CENTER switches between transmitand receive modes.The PAGE CENTER uses a Voice Operated Switch (VOX) circuit on the telephone line. VOX circuit switchesthe PAGE CENTER from transmit mode to receive mode when it detects that the audio coming in from thetelephone line has stopped.To place a telephone call:1. Press the *7keys on the two-way radio's DTMF keypad. This tells the PAGE CENTER that you wish toplace a telephone call.2. Listen for the confirmation beeps to come back from the PAGE CENTER. If autopatch operation hasbeen disabled from the Configuration Menu, then alternating high and low beeps will signal an error. Ifvoice 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 telephonenumber, you may enter a *to dial the phone number. Alternatively, the phone number will be dialed if nokeys are pressed after a few seconds. The DTMF tones being sent to the phone line will be heard toconfirm dialing.4. Once the called party answers, the phone VOX circuit takes over. When the called party speaks, the PAGECENTER transmits his or her voice.5. A periodic ticking sound will be heard by the mobile user as the PAGE CENTER briefly switches toreceive mode to determine whether the mobile user wishes to interrupt the conversation and has beguntransmitting.6. If neither party is talking, a single beep will be heard periodically to remind the mobile user that the phonepatch is still in operation.7. A timeout timer exists in order to shut down the phone patch automatically in the event that the mobile usergoes out of range or has a battery outage. Warning beeps or a voice message will be sent 30 seconds beforethe timeout timer expires and the phone call is terminated. The mobile user may press * in order to resetthe timeout timer and continue the phone call.8. End the conversation from the two-way radio by pressing the # key. A high, then low beep sequence or avoice message should be heard to confirm the disconnection.3.3 Autodial CallsThe 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 memoryyou 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.
Page Center User Manual MNT-PC-VBPage 113.4 Receiving Telephone Calls at the Two-Way radioThe PAGE CENTER can also be used to route telephone calls from the telephone line to two-way-radios. Toinitiate 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.Remote Paging Call Forwarding PAGE CENTER Operation When CalledEnabled Enabled • Phone answered with a "Enter Pager Number" prompt.• User may press * 5 to request a phone patch and send"ringing" tones to the two-way-radio users.• User may enter the number of a pager to be paged and anumeric message.Enabled Disabled • Phone answered with a "Enter Pager Number" prompt.• "Error" tones are generated if the user presses * 5 .• User may enter the number of a pager to be paged and anumeric message.Disabled Enabled • Phone answered with "ringing" tones which are also sentto the two-way-radio users to request a phone patch.Disabled Disabled • The phone line is not answered3. The telephone user must enter *5 to request a phone call if "Remote Paging" is enabled.4. If "Call Forwarding" is enabled and the telephone line rings, the PAGE CENTER will transmit a simulatedring signal over the air. To answer the call, a mobile user must press the * key to take the telephone lineoff-hook.5. Once the called party answers, the phone VOX circuit takes over. When the phone user speaks, the PAGECENTER transmits his or her voice.6. A periodic ticking sound will be heard by the mobile user as the PAGE CENTER briefly switches toreceive mode to determine whether the mobile user wishes to interrupt the conversation and has beguntransmitting.7. If neither party is talking, a single beep will be heard periodically to remind the mobile user that the phonepatch is still in operation.8. A timeout timer exists in order to shut down the phone patch automatically in the event that the mobile usergoes out of range or has a battery outage. The length of the timer is set in the Configuration Menu.Warning beeps or a voice message will be sent a few seconds before the timeout timer expires and thephone call is terminated. The mobile user must press * to reset the timeout timer and continue the phonecall.9. End the conversation from the two-way radio by pressing the # key. A high, then low beep sequence or avoice message should be heard to confirm the disconnect.
Page Center User Manual MNT-PC-VBPage 123.5 Sending Pages using the Telephone InterfaceThis 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 willanswer the phone and send an "Enter Pager Number" prompt, which is a sequence of three beeps. If voiceprompts 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 inlength, then press the *key to terminate the pager's number. Note that the *key is not used to terminatethree digit pager numbers.4. If desired, optionally pause sending beeps and listen for a low / high tone sequence, which signifies that thepager number was accepted. A series of alternating high and low beeps indicates an error in the pagernumber or a timeout occurred. If voice prompts have been enabled, then a voice message will be heardinstead 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 toindicate that the page was sent.7. After a short delay, the "Enter Pager Number" prompt will be given again. You may send another page ifdesired 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 lowbeeps or a voice message will be sent, indicating that a timeout occurred. The PAGE CENTER will thenhang-up the phone line.

The table above lists the parameters which maybe 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 EnableIf this mode is disabled, then the speaker is muted at all times except in the Diagnostics Mode. This may beused if the PAGE CENTER is in a location where sounds from the speaker are not desirable.4.1.3 Busy Channel LockoutIf this mode is enabled, then the PAGE CENTER will not transmit if the channel is busy. This may be desirablein order to avoid interfering with other users on the channel. This mode should be disabled if there is so muchactivity on the channel that the pages are not sent out in a timely manner.4.1.4 Remote PagingIf this mode is enabled, then remote users are permitted to call the PAGE CENTER via a telephone line and togenerate pages to be transmitted.4.1.5 Call ForwardingIf this mode is enabled, then remote users are permitted to call the PAGE CENTER via a telephone line and torequest a phone autopatch with two-way-radio users.4.1.6 Autopatch TimerThe autopatch timer establishes the length of time the PAGE CENTER waits before hanging up the autopatchautomatically. This is needed in case the two-way-radio user's batteries fail or he goes out of rangeEnter the number of minutes autopatch may be operated before the disconnect warning tones are sent. The DELkey may be used to delete digits. Press the "-" key to exit the menu. Note that autopatch operation may bedisabled by setting the Autopatch Timer value to 0.4.1.7 Voice PromptsThis mode selects whether beeps or voice prompts are used to confirm radio and phone operations with thePAGE CENTER.4.1.8 Warmup SignalIf this mode is enabled, then a special "warmup" signal is transmitted for a brief period of time at the beginningof each page. This is required for more reliable operation by some pagers.4.1.9 Transceiver SetupThe PAGE CENTER either contains a two-way transceiver or works with an external transceiver. In eithercase, the factory has programmed the correct Transmitter Type, Carrier Detect inversion, Transmit Datainversion and TX Bandwidth modes. The user should not change these settings or improper operation willresult.

After entering the Program Mode password(7531) and pressing F1, you can select one of the following menu items:1 = Assign Pager Assigns pager CAP codes2 = Assign Group Assigns pagers to groups3 = Test Page Sends periodic test pages4 = Alarm Pages Configures alarm triggered pages5 = autodial memory Configures Autodial memories- = RETURN TO PAGEReturn back to the page modeWhen you enter the Program Mode you will see the first selections. Use the UP/DOWN arrows to scrollthrough the available options. To exit the Program Mode, press the - (Program) key or the ESC key. Anychanges 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 (nokeyboard inputs) for two minutes, except that test pages may be sent for an unlimited period of time.5.1 Assign PagerAll 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 adatabase stored in its memory to remember every pager's CAP code. Within the PAGE CENTER, every pageris assigned a Pager Number. Because pagers only recognize CAP codes, the PAGE CENTER must translate thepager 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 PAGECENTER will respond with:PAGER No =DASH (-) TO EXIT2. 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 respondwith a prompt asking for the CAP code for this pager. If the pager number was already in the database, itwill display the CAP code already programmed. If it was not in the database, the CAP code will default tothe pager number. To edit the CAP code, use the DEL key to backspace over it. Press F1 to enter the newCAP code.3. After you enter the CAP code for the pager, you must tell the PAGE CENTER just what type of pager isbeing assigned. The PAGE CENTER will display the default type. Press the arrow keys to cycle throughthe 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 theOSMAC system must have all pagers set to 512 baud POCSAG. Once the correct paging format type is inthe 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 functiontype for POCSAG pagers is one of the following:• TONE (pager just beeps)• NUMERIC (pager beeps and displays numbers)
Page Center User ManualPage 18• 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 isdisplayed.5. If a TWO TONE or GROUP TONE pager has been selected, you will be asked to select the tone plan forthe pager. Use the arrow keys to scroll through the supported plan types. If the tone plan for your pagerisn'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 pressan arrow key to switch between Y and N on the display. Press F1 when the correct response has beenchosen.7. The PAGE CENTER will ask whether the pager changes should be saved. Press F1 to select Y if you wishto 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 thenext pager number. Press the - to exit the Program Mode when all of the pagers have been entered into thedatabase. Your entries into the pager database will then be saved in the internal FLASH memory.5.2 Assigning a GroupThe Group-Page feature is used to send the same page to a number of different pagers. Groups have numbersjust like pagers, and once you define a group and its members, you send pages to the group just as if it were asingle pager. When you assign a number to a group, it is important that the number is not the same as anyindividual pager.There is a limit to the number of pagers that may be assigned to any one group. This is listed in theSpecifications section of the PAGE CENTER User Manual.1. To do the group assignments, select 2-Assign GROUP from the program mode menu. The display willthen show:GROUP NUMBER =SELECT GROUP2. Enter the number of the group you wish to work on and then press the F1 key. Valid group numbers are 1through 16. The display will then show:GROUP X PAGER NNassign pager numberWhere 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 thegroup number.3. Use the DEL key to backspace over NN if you wish to change the pager number this group is referred toby. If the pager number NN is already assigned to an active pager, the PageCenter will not allow you toassign that number to the group and the pager number will be erased. If you wish to use NN for a groupnumber instead of an individual pager, you must first de-activate the pager. Section 3.1 describes how to
Page Center User ManualPage 19deactivate a pager. Once the pager number for this group is set, press the F1 button. The following promptwill appear.GROUP X = numericSELECT GROUP FUNC4. Using the arrow keys, select the function (numeric, alpha or tone) for this pager group. Members of thegroup may be of any type, but this selection will determine the prompt to the user when a page to this groupis initiated. Press F1 when your selection is made. The display will change to :GROUP X MEMBER NNENTER MEMBER NUMBER5. X will be the group number you are currently working on, and NN will be a number corresponding to themember number you wish to edit. The first group member you enter will be member 1. The second oneyou enter will be member 2 and so on. The display always first shows the next member number you canenter a new member as. Use the UP/DOWN arrows if you wish to scroll through the members, or press theDEL key to edit the member number and manually enter the member number to edit. Press F1 key whenyou are ready to edit/add the selected group member. The display will then show:MEMBER NN =ENTER PAGER NUMBER6. Enter the number of the pager you wish to add to the group. For example if you wish to add pager number123 to the group, then enter 1 2 3 and then press the F1 key. Use the DEL key to backspace over any entryif 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 toscroll through the members of the group.• To delete a member, at the MEMBER NN = prompt, use the DEL key to erase its number from thescreen, and press the F1 key.7. To finish entering pagers to this group, press the - key.5.3 Sending Test PagesThe test page mode may be used to check the range of the system. With this mode, the PAGE CENTER willautomatically generate a page to pager number "0" every ten seconds.1. Before using this feature, pager number "0" must be programmed as described above.2. To enable this feature, enter the program mode and press 3. The display will show:PAGING pAGEr 0dash (-) to exit3. Press the - key to return to the programming mode menu.5.4 Alarm PagesThe PAGE CENTER has 8 alarm inputs. These digital inputs are used to generate pre-programmed pages, eachwith its own pre-programmed message to any pager, or group of pagers. These may be used for alarms, but theymay 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, itwill generate a pre-programmed page. When any input is pulled high or allowed to "float high", it will generatea different pre-programmed page.
Page Center User ManualPage 20Alternatively, alarm pages may be initiated from an external keyboard. Hold down the CTRL key and thenpress a number key which corresponds to the alarm input number to send the "Alarm Low" message. Holddown 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. SeeSection 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. Put the unit into the program mode.2. Press 4 to enter the Alarm sub-menu.3. When the ALARM NUMBER = prompt is shown, enter the number of the alarm you wish to configure.Press the F1 key.4. The PAGE CENTER will display AlaRM x PAGER on the top line, and the pager number that will bepaged when the alarm is triggered. Erasing the pager number disables the alarm. Enter the number of thepager you wish to have paged when the selected alarm input is triggered. Press F1 when done.5. PAGE CENTER will display ALARM low MSG: on the top line of the LCD. On the second line, you mayenter or edit the message to be sent when the alarm input goes low. Press F1 when the message has beenentered.6. PAGE CENTER will display ALARM hi MSG: on the top line of the LCD. On the second line, you mayenter or edit the message to be sent when the alarm input goes high. Press F1 when the message has beenentered.When entering the alarm messages, the unit's keys operate as follows:• Numeric keys are used to enter numbers• F4 or UP keys select the next letter of the alphabet• F3 or DOWN keys select the previous letter of the alphabet• - key enters a "dash" character• F2 key enters a space character or moves to the next character position to the right• DEL key deletes a character and moves to the next character position to the left• F1 key accepts the entry and exits back to the previous menu.• Alphanumeric characters may alternatively be entered directly from an external keyboard7. Press the F1 key to return to the programming mode menu.5.5 Phone Autodial MemoriesThe PAGE CENTER has 10 Phone Autodial Memories. These must be programmed prior to use by two-way-radio users. To program the autodial memories:1. Enter the number of the autodial memory to be examined. Alternatively press the arrow keys to cyclethrough the memories. The first 20 characters of the autodial memory's phone number will be displayed.Note that each phone number may be up to 30 characters in length.2.

Page Center User ManualPage 237 Serial Port ProtocolsThe PAGE CENTER paging transmitter supports three different serial port communication protocols. Eachprotocol has its own uses, and the correct one for one application may not be the correct one for another. ThePAGE CENTER must be configured to support the desired protocol, and only one protocol may be used at atime. The three protocols supported are:TAP (also called IXO) The Telocator Access Protocol is an industry standard protocol forcommunications 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 aperson with a simple computer terminal to type a message into the PAGECENTER. The PAGE CENTER must be pre-configured with the CAPCODE ofthe pager to send the data to, and all data sent into the serial port of the PAGECENTER will be sent to that one pager.COMP2 COMP2 is similar to COMP1, except each page requires two lines of text to beentered. The first line is the pager number to send the page to, and the secondline is the alpha or numeric message to send to that pager.7.1 TAPThe Telocator Alphanumeric Protocol, or TAP protocol as it is called, is used to send pages to communicatepaging 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 thePAGE CENTER Station is directly connected to it via a serial cable. If other means are used (i.e. modem) thenthe modem connection must first be established. For the purposes of this manual, the PAGE CENTER isassumed to be the transmitter, and the device connected to its serial port is the "Entry Device". Typical entrydevices are computers, paging terminals, and alarm monitors. Characters listed in brackets <xx> are ASCIIcodes, and the values for them are listed at the end of this document.Initiating a PageEntry Device PAGE CENTERAction Comment<CR> The Entry Device should send a <CR> at two second intervalsuntil the PAGE CENTER responds with the characters ID=.The <CR> is an ASCII code 13h.ID=<CR><LF> The PAGE CENTER will respond within one second of the<CR>, and it does not end the ID= prompt with a <CR> or a<LF>.
Page Center User ManualPage 24After initiating a page, and receiving the ID= prompt, the Entry Device can respond in one of two differentways. One way puts the PAGE CENTER into an Automatic Mode, and the other ways puts it into a ManualMode.Automatic Entry of a PageEntry Device PAGE CENTER Action Comment<ESC>PG1<CR> The Entry Device tells the PAGE CENTER transmitter that itwants to automatically send a POCSAG page by ending thissequence.<CR><ACK><CR>or<CR><NAK><CR>or<ESC><EOT><CR>The PAGE CENTER will respond within one second of theACK sequence signifying that the Entry Device hassuccessfully logged on to the PAGE CENTER.

Goodby.<CR>One of these messages will then be sent fromthe PAGE CENTER, depending upon thecurrent 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 ifthe user does not complete the page in thattime.7.2 TAP Protocol Issues7.2.1 TimingThe PAGE CENTER will only wait for 15 seconds for a response to come back from the Entry Device. If aresponse is not received before the time-out period, the PAGE CENTER will cancel the current transaction,sending the <ESC> <EOT> <CR> sequence.7.2.2 Line FeedsThe PAGE CENTER will ignore all <LF> characters it receives. The Entry Device may send a <LF> with any<CR>.XOFFIn the very unlikely event that the user enters more pages than the PAGE CENTER can queue up, the PAGECENTER will send the <XOFF> character before sending a carriage return. It will send the <XON> characterwhen buffer space is available for more pages. If the PAGE CENTER does not receive data within 10 secondsafter sending an <XON>, it will send another <XON>.
Page Center User ManualPage 267.2.3 EOTWhenever the PAGE CENTER terminates a session by sending the <EOT><CR> sequence, it will drop theDTR signal on the RS-232 signal for 250mS. This will normally cause any modem connected to it todisconnect.7.3 Sending Multiple-Line PagesIf you wish a message to continue on another line of a multi-line pager, you cannot send the <CR> return intothe serial port. Use the TAB character instead of a <CR>. The PAGE CENTER will translate it to a <CR>when it sends the page to the pager.7.4 Computing the ChecksumThe checksum is a simple arithmetic sum of the 7-bit values of all characters preceding it. The checksumreported is the least significant 12 bits of this summation, converted to BCD ASCII.Checksum Example:STX 000 00101 011 00012 011 00103 011 0011<0CR> 000 1101A 100 0001B 100 0010C 100 0011<CR> 000 1101ETX 000 0011Total 10111 1011Convert to BCD 1 0111 1011Answer in BCD ASCII 17 ;7.5 COMP1COMP1 allows a "dumb terminal" to be used to send a page, although any device that can output RS-232 datacan be used.All data entering the serial port is sent to a pre-set pager.

Use aterminal emulation program to send the ASCII file into either serial port in a plain-text format. The serial portmust 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 wasan error in it. If any errors occur during uploading, a message will be displayed at the end of the uploadsequence and the information received will not be saved. If this occurs, reduce the data rate of the port in use orenable 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 sentto it. The word “DONE” at the end of the file tells the PageCenter that the file has been sent. Once the word
Page Center User ManualPage 31DONE is received by the PageCenter, it will copy the database into its FLASH memory only if no errors weredetected.8.3.1 Erasing Pagers or Groups from the DatabaseUploading the database file to the PageCenter only adds and re-programs the pagers and groups specified. Itdoes 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 thedatabase. 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 fromthe ASCII file. If you only wish to erase the group information, and not the individual pagers, put a line in thefile that reads:ERASEGROUPS[0D]8.3.2 Programming Two-Tone Pagers with Non-Standard FrequenciesTwo-tone or group-tone pagers using non-standard frequencies and durations may be programmed via thedatabase upload command. Use a text editor to create an entry in the database file for the pager as followsbefore uploading the file to the unit:PAGER,{0-999},{TYPE},{CAPCODE},{FORMAT},N,{ACTIVE},{DUR-A},{DUR-B},Where:PAGER Signifies that this line is the data for a pager{0-999} Pager number for the pager{TYPE} Pager type: TONE, ALERT or VOICE{CAPCODE} 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{FORMAT} Paging format: TWO-TONE or GROUP-TONE{ACTIVE} Is either Y is the pager is enabled, or N if it is de-activated{DUR-A} Duration of the first tone in units of 50 mS{DUR-B} Duration of the second tone in units of 50 mS. Set to 0 for group-tone pagers.8.3.3 Programming the Unit's ConfigurationThe unit configuration data stored in the SERIAL, MODE, RADIO and AUTODIAL entries are normallyignored when the database file is uploaded to the PageCenter as a security feature in order to preventunauthorized users from changing the unit's configuration.If it is desired to change the PageCenter's configuration with data downloaded previously from a PageCenterunit, 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 frontpanel.
Page Center User ManualPage 329 Firmware UpdatingThe firmware in the PageCenter can be loaded with firmware updates via the serial port number 1 (lower of thetwo serial ports).Note that you might need to reset the Flash memory and reload the database of pagers after you load the newfirmware into the unit. Before updating the firmware, it is recommended that the pager database be downloadedand 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 programsuch 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 thePageCenter that looks like this:PageCenter software installation utilityCopyright (c) 1999, Sonik Technologies Corp.San Marcos, CAVersion: 306D1Erase 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 oneprotocol 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 uploadthe pager database previously saved.
Page Center User ManualPage 3310 External Connectors10.1 External TransceiverThe PAGE CENTER may utilize an internal transceiver, an external transmitter, or an external transceiver. A15 pin D-sub connector is located on the rear of the PAGE CENTER to facilitate interfacing an externaltransmitter or external transceiver to the PAGE CENTER. The pin-out of this connector is as follows:External Transceiver I/O Connector Pin OutPin Number Function1 Ground2 B+ for the radio. Internally jumper selectable between +8V and +12V. 1 Amp maximumcurrent draw.3 +8V TX. This pin floats when in the RX mode, and will be pulled to +8V when in the TXmode. 50 mA maximum current source.4 +5V for radio. 50 mA maximum current draw.5 +5VRX. This pin floats in the TX mode, and will have +5V when in the RX mode. 50 mAmaximum current source.6 TX audio. Approximately 1.7V p-p for full system deviation. 2.5V DC nominal bias onthis signal.7 PTT out. Open collector output, pulls low to ground when the transmitter’s PA should beon.8 Do not use and do not connect to anything.9 Do not use and do not connect to anything.10 Do not use and do not connect to anything.11 TX data out. This is the TTL POCSAG data output in the transmit mode.12 Receiver signal strength indication input. Positive voltage represents carrier present onchannel.13 RX audio input. 1.0V p-p for a signal with full system deviation.14 CTCSS tone encoder output.15 Do not use and do not connect to anything.10.2 Serial I/O PortsThe PageCenter has two RS-232 type serial I/O ports on it. The EIA/TIA RS-232, and the equivalent EuropeanCCITT V.28, are electrical standards that cover the signal levels, drive level, and slew rate of compliantdevices. It is important to note that they do not specify baud rates, data formats, or connector pin-outs. Theseare set by industry standards and practices.Equipment using RS-232 ports is grouped into two categories:DTE Data Terminal Equipment (computers, mainframes, terminals)DCE Data Communications Equipment (modems, printers, etc.)The PageCenter is wired as a peripheral (DCE) device.
Page Center User ManualPage 34The control lines on the serial port are used for controlling the flow of data and the peripheral attached to theport. The most signals provided for on RS-232 serial interfaces are shown in the following table:Pin # Name Typical RS-232 Serial Signal Functions3 TXD Transmit data from the computer to the PageCenter.2 RXD Receive Data from the PageCenter to the computer.7 RTS* Request to send data. This is an output from the computer to thePageCenter. It indicates to the PageCenter that it is ready to exchange data.8 CTS* Clear to send. This is a signal from the PageCenter to the computerindicating that it is OK to send data.4 DTR* Data Terminal Ready to the PageCenter. This signal indicates to theperipheral that the host is ready to receive data.1 DCD* Data Carrier Detect from the PageCenter.9 RI* Not implemented.6 DSR Data Set Ready from the peripheral. Indicates the peripheral is ready.5 GND 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) toassert them and binary one (1) to negate them. Over an RS-232 cable, they are again inverted because RS-232 specification calls fornegative logic. Negating RTS is a binary 1, which is a negative voltage on the RS-232 port.10.3 Auxiliary/Alarm ConnectorA 15 pin D-Sub female connector is located on the rear of the unit. This connector has digital inputs used fortriggering alarms. It also has contacts for two relay outputs. The digital inputs may be programmed toautomatically generate a page or dial the phone. The relay outputs may be switched on remotely via thetelephone, radio, or console.Note that all digital alarm inputs have an internal 10K pull-up resistors connected. Alarms are activated bypulling the input to ground. Open circuit or a TTL/CMOS high level is the inactive state. Do not pull theseinputs above 5V.Auxiliary/Alarm I/O Connector Pin OutPin Number Function1Alarm 82Alarm 73Alarm 64Alarm 55Alarm 46Alarm 37Alarm 28Alarm 19 Relay 1 contact A10 Relay 2 contact A11 Relay 2 contact B12 Relay 1 contact B13 No connection14 No connection15 Ground10.4 Keyboard ConnectorThe PageCenter may be used with standard external keyboards for use with Personal Computers which havePS-2 style connectors.
