Pager Types
The SmartAlert 200 Series RS232 can be programmed to work with several
types of JTECH Communications pagers. Most commonly, these include
Numeric and Alphanumeric (Alpha) pagers, although pager types may also
include Vibe Only, Vibe/Tone, Glowster and CommPass Vibe/Flash and
Vibe/Flash/Voice pagers. Please refer to the instructions that accompanied your
pagers for installation and operation or request the UHF Desktop Transmitter
product documentation (P/N 325005) for complete details on these JTECH
paging products.
JTECH pagers conform to a number of industry standards. Seven (7) variables
are typical of most pagers. These variables are:
1.
2.
3.
4.
5.
6.
7.
Language Recognized: POCSAG
Message Protocol: Alphanumeric or Numeric Only
RF Baud Rate: 512, 1200, or 2400
Data Inversion: Yes or No
Priority Message: Yes or No
Cap Code: Up to 2 Million individually accessible codes
Receive Frequency
These variables along with other pager terminology are described in the next
section.

Programming Terminology for the SmartAlert RS232
Language
Over the years a number radio frequency data patterns (Languages) have evolved to
“speak” to pagers. POCSAG is the most widely used language today and a language
that JTECH products support. POCSAG is simply an algorithm that is used to encode
alphanumeric and numeric data for transmission via modulated radio waves.
Message Protocol
Two types of data may be sent to today’s pagers, either numeric only or alphanumeric.
Numeric only data is easier to decode and may be received on less costly pagers.
Alphanumeric data is more flexible than numeric only, but is more difficult (expensive)
to decode and display and therefore must be received on more expensive pagers. The
received radio data for Alphanumeric POCSAG messages are different in format than
numeric only messages and therefore will result in “garbage” being displayed when
alpha messages are sent to numeric only pagers. The opposite is also true. JTECH
Communications, Inc. uses a specific descriptor in the format used to “Talk” to its
transmitters to allow the user to select either alphanumeric or numeric only protocol.
(This option is only available when using 7 digit extended protocol). The actual
modulated radio waves sent in alphanumeric messages versus numeric only messages
are different even though the content may appear the same. For example, the radio
waves received by a numeric only pager that is to display the message ‘123’ will be
quite different than the radio waves received by an alphanumeric pager that is to
display the message ’123’.
RF Baud Rate
Radio Frequency baud rates are the rates at which radio transmitters modulate
radio waves into the “1’s” and “0’s” received by pagers. The most common RF
baud rate is 512 baud, but 1200 baud and 2400 baud are increasing in
popularity. JTECH Communications, Inc. uses 512 baud, but our transmitters will
support 1200 and 2400. Testing to date has shown 2400 baud to be slightly less
reliable than either 512 or 1200. Faster data rates are used primarily by wide
area paging services where throughput is a critical concern. For example, at
peak paging times, a citywide paging service would be able to send four times
the number of pages by using a 2400-baud rate vs. 512 baud. On-site systems
simply do not have the traffic to necessitate the use of higher baud rates. The
observable difference may only be one to one and a half seconds faster with
2400-baud versus 512 baud. With the higher reliability of 512 baud the
difference in speed is not enough to offset this reliability difference. JTECH uses
a specific descriptor in the format used to “Talk” to its transmitters to allow the
user to select either 512, 1200 or 2400 baud.

Receive Frequency
The receive frequency is the center frequency measured in millions of cycles per
second that a pager is tuned to. A single frequency may typically supports
hundreds of thousands of pagers and it is the Cap Code that allows specific
identification of an individual pager. For a pager to operate, the frequency of the
transmitter (SmartAlert RS232) must match the receive frequency of the pager.
Radio Frequency (RF) Baud Rate vs. RS-232 Baud Rate
JTECH equipment, which connects via an RS-232 connection, communicates
between the host and the hardware at 1200 baud.
The term “baud rate” has also been associated with the frequency at which radio
waves designating “1’s” and “0’s” arrive at a pager (see page 3.) This RF baud
rate is often confused with the baud rate of “1’s” and “0’s” arriving at the
transmitting equipment from the host. Typical RF baud rates are 512, 1200 and
2400. JTECH supports 512, 1200 and 2400 baud pagers.
Data Inversion
Radio data sent to pagers may be sent either right side up (non-inverted) or
upside down (inverted). It is not clear where this option originated, but it
nevertheless persists. Most commercially available pagers have the option of
accepting either orientation, however, the pager supplier usually sets this option
and therefore either non-inverted or inverted data must be received, but not both.
This pager option is not usually field selectable and must be “downloaded” to the
pager via special equipment available from most paging dealers. Data noninverted is the most common data orientation. JTECH uses a specific descriptor
in the paging format used to “Talk” to its transmitters to allow the user to select
either a non-inverted or inverted data format. (This option is only available when
using 7-digit extended protocol.)
Priority Message
Some pagers support an option that allows the sender to indicate a “High Priority” page.
These types of pages usually cause a vibration pager to “Beep” indicating a high priority
message has been received. Ordinary priority messages sent to vibration pagers cause
the pager to simply vibrate. This pager option is not usually field selectable and must be
“downloaded” to the pager via special equipment available from most paging dealers.
JTECH uses a specific descriptor in the paging format used to “Talk” to its transmitters
to allow the user to select either a normal priority or high priority message.

Cap Codes
POCSAG pagers must receive a special seven-digit “address” to let it know that
the message that follows is for this particular pager. Since thousands of pagers
will share a common frequency, a method must exist that allows a single pager
among these thousands to respond and all others to remain silent. A system of
addresses has been developed that allows all pagers on a common frequency to
hear all pages, but only the individual pager whose address was sent to actually
signal and display the message. This “Address” is referred to as Cap Code. A
Cap Code is the actual seven-digit number that must be received by a POCSAG
pager to have the pager receive a message.
Pager Number
Pager Number often refers to the one to four digit number placed on a pager label. In
systems that support cross reference tables, the Pager Number may only be the
number on the label of the pager and only serve as a cross-reference to its actual Cap
Code. For example, to simplify use by an end user, you might label a pager with a
phone extension of #002, and your computer software may associate pager #002 with
cap code 0000016.
Numeric Pager
Numeric pagers sold by JTECH are capable of displaying 1 to 16-digits. A
numeric pager will not display an alpha message. When this class of pager is
targeted to receive a page it must receive a numeric only radio transmission. If a
numeric only pager receives an alphanumeric transmission sent to its cap code it
will attempt to decode the message and will then display ‘garbage’ on the
screen. Numeric only pagers are not ‘smart’ enough to know not to attempt to
display alpha data. Therefore the software sending the transmission must be
smart enough not to send alphanumeric data to numeric only pagers.
Alpha Numeric Pager
Alphanumeric pagers are capable of up to 120 alpha or numeric characters.
Most will display an alpha message as well as a numeric message. When this
class of pager is targeted to receive a page, it may receive either numeric only or
alphanumeric data and if the pager is properly set up, it will display either type of
data properly. Alphanumeric pagers require special set up and adherence to
special transmission rules to properly display both alpha and numeric only radio
transmissions.
Multiple Cap Code Pagers
Many pagers are able to have multiple cap codes which are useful for group
paging. The number of cap codes for pagers varies depending on the
manufacturer and model.

Communication Protocol
The SmartAlert Transmitter requires, in addition to the correct physical
interconnection, that the proper RS232 protocol be followed. That protocol is:
•
•
•
•
1200 baud
8 data bits
No parity
1 stop bit
In addition, the proper message format must be followed. The message format
descriptions follow.
RS232 Interface Hardware Handshaking-Request To Send / Clear To Send
While the SmartAlert transmitter does not monitor RTS, it does toggle Clear to
Send (CTS) to allow it to meter data out of the Host output buffer. Therefore, the
Host must observe CTS from the transmitter and never send any data while CTS
is low. Any data sent while CTS is low will be lost!
The SmartAlert transmitter uses only CTS to indicate when it is OK to send data
to the unit. The SmartAlert transmitter expects the host will cease sending data
immediately upon dropping CTS from High to Low.
Some specialized high-speed serial port drivers will buffer up to 16 characters
and will continue to send data long after CTS has dropped. This causes
important data to be lost since the SmartAlert transmitter is not paying attention
to the incoming data while CTS is low. Generally these specialized high-speed
serial port drivers allow you to set the amount of data that will be buffered and
therefore sent upon the dropping of CTS. If this is your situation, set this
parameter to 1 or 0.
Windows 95 & Windows 3.1X serial port drivers perform as expected and cease
sending characters immediately upon the transition of CTS from High to Low.
Baud Rate
The RS-232 baud rate required by the SmartAlert transmitter is summarized
below:
•
1200,N,8,1 (1200 Baud, No Parity, 8 Data Bits, 1 Stop Bit)
SmartAlert 8214/8205 Programming/Installation Guide

Message Format
The recommended format is the 7-digit extended format. The 7-digit extended
format consists of six parts:
1.
2.
3.
4.
5.
6.
Preamble
Function Bit (not used in the 3-digit message format)
Cap Code
Separator
Pager Message
Terminator
A code sample is shown below. Please refer to this example as you read
through the sections that describe each part of the message. The 7-digit
extended message format is the recommended format to use for application
developers wishing to exploit the maximum amount of flexibility out of their pageenabled application. This format allows the SmartAlert transmitter to access
three types of pager baud rates (512, 1200, 2400), two types of pager data
(alphanumeric and numeric only), all four function bits (01 through 04) enabling
priority messaging, and two types of messages (Non inverted and Inverted).
Below is an excerpt from a simple visual basic software program utilizing 7-digit
extended format, which will result in a non inverted, priority page, to a 512 RF
baud alphanumeric pager:
MSComm1.PortOpen = True
‘Opens Serial Port for Communication
Preamble = Chr$(255) & Chr$(255) & Chr$(255)
FBit = Chr$(03)
‘Set Function bit #3
Cap Code = “2049999”
Separator = Chr$(10)
‘This is an Non Inverted,512 RF baud, Alpha Page
PagerMessage = “This is a test Page”
Terminator = Chr$(13)
OutPutString = Preamble & Fbit & TargetPager & Separator & PagerMessage & Terminator
MSComm1.Output = OutPutString
Example Data Stream Into 8214: (Expressed in hex)
FF FF FF 03 32 30 34 39 39 39 39 0A 54 48 49 53 20 49 53 20 41 20 54 45 53 54 20 50 41 47 45 OD
| F |Cap Code:2049999 | S|
Message: THIS IS A TEST PAGE
|T|
P = Preamble
F = Function Bit (Byte)
Cap Code = Seven Digits
S = Separator
Message = Up to 120 Characters
T = Terminator

Details of the Message Parts
1. Preamble
Preamble is a string of three hex characters used to provide “padding” between
messages in an output buffer as well as information to the SmartAlert transmitter
that a paging message is on its way. The Preamble is Chr$(255) & Chr$(255) &
Chr$(255)
2. Function Bit
The function bit is actually a byte and is a single hex character, which follows
immediately after the preamble. This character signifies to the SmartAlert
transmitter which function bit to “Turn On” in the POCSAG message that is sent.
The selection of function bits in the transmitted message allows the application
developer to exploit various functions, which reside inside the pager. Function
bits in the transmitted message by themselves do not evoke functions from the
pager, rather they must match functions which are pre-programmed into the
pager before they cause a pager to operate in a particular fashion. For our
purposes here, one of four hex characters are available to select function bits in
the transmitted message. Hex 01 to hex 04 are the acceptable characters. The
following table shows, which function bits, evoke what pager reactions.
Function Bit
(Only One May Be Set)
Function Bit #1 Enabled
Function Bit #2 Enabled
Function Bit #3 Enabled
Function Bit #4 Enabled
Function accessed from Pager
Non Priority Alert for Numeric Only Pagers
Priority Alert for Numeric Only Pagers
Non Priority Alert for Alphanumeric Pagers
Priority Alert for Alphanumeric Pagers
3. Cap Code
Cap Code for 7-digit extended Message Format
In the seven-digit extended format no assumptions or cross-references are made
and the seven-digit pager cap code sent is the actual seven-digit pager cap code
received by the pager. Application developers will find the seven digit extended
format provides maximum flexibility.
Important note: If the cap code prefix of 000 is used, the SmartAlert transmitter
recognizes this as the JTECH “times 8” (X8) cap code scheme. The transmitter
multiplies the ‘cap code’ number provided by 8 prior to transmission to the pager.
For example, the JTECH pager may have two labels. One will be the ‘pager ID’
number the other will be the cap code number. The pager ID number will be the
cap code divided by 8. With the times 8 scheme, be sure to use the pager ID
number in your program. All other cap codes using valid prefixes will be sent as
entered into the program.

Page 9
4. Separator
A separator is used to separate the Cap Code from the actual message to be
displayed. The separator in the 7-digit extended format provides three additional
pieces of information to the SmartAlert transmitter. That information is what type
of pager that is to be spoken to (alpha or numeric only), what baud rate is to be
used (512, 1200, or 2400), and inverted or non-inverted data.
The default Radio Frequency Baud Rate is 512 RF baud. However, many pagers
available today require 512 RF Baud, 1200 RF Baud or 2400 RF Baud. The 7
digit extended format allows access to these 1200 RF baud and 2400 RF baud
pagers. The capability of sending priority messages to both alpha and numeric
only pagers is also available in the 7-digit extended format. The table below
depicts the acceptable combinations for various RF baud rates, alphanumeric
paging and numeric only paging, inverted and non-inverted data, as well as the
implementation for priority and non-priority messaging using the 7-digit extended
message format.

Hardware Installation
The SmartAlert Transmitter is wired directly to a communications port on your
host device. This may be a Personal Computer or other electronic device and to
any analog phone jack on your telephone system. The first consideration in
installation is regarding the placement of the SmartAlert Transmitter. It should
be as high as possible and must be located within the length of the
communications cable. RS232 cable length maximum is 50 feet. The next
consideration involves safety. Be sure the unit is securely mounted and safe
from liquids, extreme heat, and possible physical damage.
The antenna must be vertical. As with any transmitting unit, pay close
attention to obstructions when locating antenna. Wall, pipes, ducts, mirrored
glass, or other similar barriers may weaken or misdirect transmitted signals.
Certain materials and construction, especially metal, have the potential to
partially or completely block the signal. Also remember that the SmartAlert
Transmitter requires an 110V outlet for power.
Follow the directions below for the SmartAlert model 8205 RS232 with
Telephone Interface
1. Attach the antenna to the BNC antenna port marked A1.
2. Connect one end of the RJ-11 phone cord to the phone jack marked J2 on
the front of the unit and the other to an available phone jack line in your
telephone system. The Phone Interface requires an analog phone jack; the
Phone Interface must be able to hear the tones from a push button
telephone. Please refer to the section titled ‘Telephone Interconnect
Specifications’ for additional help in determining the type of phone line.
Continue with step two below.
SmartAlert 8214/8205 Programming/Installation Guide
320124E
Page 11
Follow the directions below for the SmartAlert
1. Attach the antenna to the BNC antenna port marked A1.
2. Attach the male end of DB-9 straight through cable to the female DB-9
connector located on the front of the SmartAlert transmitter. The PC requires
only a straight through DB-9 male to DB-9 Female cable. The SmartAlert is
configured as a DCE device and does not require a Null Modem cable.
3. Attach the female end of the DB-9 straight through cable to the male DB-9
serial port connector on the Host PC. If only a male DB-25 serial port
connector is available, you must purchase an adapter. This standard adapter
has a male DB-9 on one end and a female DB-25 on the other.
4. Note: All cables and the antenna must be connected before applying power
to the SmartAlert transmitter unit. Insert wall adapter into power connector
located on front of SmartAlert transmitter. Insert wall adapter into standard
110V AC-wall outlet. After a brief (15-second) power up sequence, the right
and left indicator lights on the SmartAlert transmitter will begin to slowly blink
in an alternating fashion indicating a ready condition. The unit is now ready
to accept data at 1200 baud, 8 data bits, no parity and 1 stop bit on the
RS232 port or input from a telephone (with telephone interface only).
Operation
Paging a Single Pager using the Telephone Interconnect
1. Pick up the receiver, listen for the dial tone and dial any of the system
extensions that have been assigned to the Paging System. A beep indicates
the system is ready for you to enter the pager number.
2. Within 4 seconds press the number of the pager (up to four digits) you wish
to page using the telephone keypad.
3. Press the * key to indicate you wish to enter a message for a numeric page
or press the # key to send a vibrating page. If you select a vibrating page a
beep will be heard verifying the message was sent.
4. For a digital page, enter a message up to 12 digits. If the message is 12
digits, a beep is heard once the 12th digit is entered. This tone indicates the
message has been sent. Press the pound (#) key on the phone keypad to
send the page if the message is less than 12 digits. A beep is heard verifying
the message was sent.
5. Hang up the receiver.
SmartAlert 8214/8205 Programming/Installation Guide

Group Paging Using the Telephone Interconnect
Group paging works with numeric pagers only.
1. Pick up the receiver, listen for the dial tone and dial any of the system
extensions that have been assigned to the Paging System. You will hear a
single beep indicating the system is ready for you to enter the group number.
2. Within 4 seconds press the * key and the number of the group (1-9) you wish
to page using the telephone keypad.
3. Press the * key.
4. Enter a message up to 12 digits. If the message is 12 digits, a beep is heard
once the 12th digit is entered. This tone indicates the message has been
sent. Press the pound (#) key on the phone keypad to send the page if the
message is less than 12 digits. A beep is heard verifying the message was
sent.
5. Hang up the receiver.
Troubleshooting
If you cannot page from a telephone, ensure that the Telephone Interconnect
has power. The indicator lights (L1 and L2) should be blinking slowly, in an
alternating fashion.
L2 will turn on while the phone is ringing and will flash when digits are received.
L1 will flash as the digits are entered. L1 and L2 will continue blinking slowly
after the phone interface hangs up the phone line.
If the extension rings continually without answering, check the following:
1. The phone Interface is powered on (watch L1 and L2).
2. The phone lines assigned to the Paging System from the phone system
switch are connected to the Phone Interface.
3. The hunt group in your phone system is set up for only one extension
connected to the Phone Interface.
If the extension rings, the SmartAlert transmitter with telephone interface
answers and if you hear the initial beep, but the SmartAlert transmitter with
telephone fails to respond, please refer to the section titled ‘Telephone
Interconnect Specifications’.

in, attach the return address label to the outside of the box (this label also includes your
RMA number) and return it to us. All returned shipment costs are the responsibility of
the client. Advance Replacement services are also offered on most pager products for
your convenience. Ask your Customer Care Representative about purchasing this
value-added service.
When return-shipping products to JTECH, we recommend equipment be shipped in a
traceable manner for your protection. US Mail is not a recommended method of
shipment. Any equipment not received by JTECH Communications within 20 days will
be billed to the client at full retail value.
There are no charges for repaired equipment within the warranty period other than your
shipping costs. There may be an additional charge if, after the item is returned and
analyzed, it is determined to be “non-salvageable” - for example, liquid damage, abused
or misused. The standard warranty does not cover the replacement of adapters,
antennas, pager belt clips, pager promobacks, pager battery doors, user-replaceable
rechargeable batteries, pager neck chains, liquid damage to master transmitter and
pagers, lightning strikes or other acts of God that could affect the performance of the
master transmitter, pagers and peripherals.
Check with Customer Care for extended warranty options, as well as the latest charges
for repair or replacement of equipment that is out of warranty. All non-warranty repairs,
pager replacements and the shipment of parts are sent on a C.O.D. basis. Any order
returned to JTECH is subject to a restocking fee. Refunds are on product and tax only.
JTECH Communications is committed to providing reliable and responsive service to our
clients. We believe that our service is the most responsive, comprehensive and costeffective program in the industry.

Appendix A - Telephone Interconnect Specifications
Telephone Interfacing
Phone Line Interface – The SmartAlert transmitter with telephone will accept
input from end-to-end (line level) telephone circuits. Selector or trunk level input
is not possible. The phones and phone system must be capable of DTMF and
provide a Bell standard ringing voltage.
PABX Interface – The PABX (Private Automated Branch Exchange) must pass
DTMF tones, and Ringing Voltage, for the SmartAlert transmitter with telephone
to work. A simple test can be used to see if DTMF tones are passed through the
telephone system. Dial a phone extension and depress any of the keys on the
phone pad. If the party you called can hear tones, then the system does pass
DTMF. Because many of the newer PABX’s are digital systems, they may not
pass DTMF. In this situation, the customer must install a separate DTMF
capable end-to-end phone line for the SmartAlert transmitter with telephone.
Special feature phone consoles may not use DTMF signaling and you can also
use the test described above to test the phone consoles.
Key System – Some customers may not have a PBX, but may have multiple
telephone lines, which are connected to numerous phone sets with push buttons
to activate “pick up”. In this situation, a separate telephone line should be
dedicated to the SmartAlert transmitter with telephone and users would dial a 7digit phone number to access the SmartAlert transmitter with telephone.
Telephone Interconnect Description
The SmartAlert transmitter with telephone’s interface is that of a very basic ‘Line
Level’ hook-up which operates in the following manner:
•
The telephone system supplies ‘battery’ voltage across Tip and Ring. When
measured from ground ‘-48’ volts will be seen on Ring while ‘0’ volts (ground),
will be seen on Tip.
•
When someone picks up a phone and enters the phone number to the
SmartAlert transmitter with telephone, the telephone system applies an
interrupted ‘Ringing’ voltage (two seconds ring, four seconds rest) across Tip
and Ring. Ringing voltage is an AC signal, which is usually around 105 volts
rms.
•
The SmartAlert transmitter with telephone's module detects the ringing and
recognizes it as a request for seizure. The encoder’s telephone module goes
off hook, energizes a relay, and puts a low impedance closure across Tip and
Ring, back to the telephone system.

Page 15
•
The telephone system then detects current flowing from its source of battery,
through the SmartAlert transmitter with telephone's loop closure, and back to
the telephone system. The current flow energizes relays in the telephone
system, which connect bi-directional audio lines through Tip and Ring to the
SmartAlert transmitter with telephone.
•
Once connected, the SmartAlert transmitter with telephone prompts the caller
to enter a pager number. The caller must enter this number via a true DTMF
tone type telephone. The DTMF tones must be at least 50 msec in duration
with a 50 msec pause between digits. Numbers entered via Rotary dial, or
Digital phone systems are not recognized by the SmartAlert transmitter with
telephone.
•
Termination of the call can be accomplished in three different ways:
1) The calling party hangs up their telephone before the SmartAlert
transmitter with telephone times out. This terminates the call at the
telephone end, but not at the encoder’s end. The disconnect created by
the caller hanging up its phone never makes it through the connection
between the telephone system and the SmartAlert transmitter with
telephone. To overcome this loss of a disconnect signal the encoder uses
an ‘inactivity timer’ which will time out and terminate the call, in the
encoder, after a loss of audio on Tip and Ring for approximately four
seconds.
2) The SmartAlert transmitter with telephone times out before the calling part
hangs up the telephone; this terminates the call at the encoders end.
3) The calling party enters the correct string of digits described in the section
‘Paging a Single Pager Using the Telephone Interconnect’. When the last
(#) pound key is pressed the page is sent and the call is terminated.
