2 OVERVIEW
The PDE-1 is a multi-format paging and dialing
encoder. It will support up to 10 different formats
simultaneously from the over 35 available. The user-
friendly menu system makes it as easy to use as a cell
phone.
2-Tone Formats: AVCALL, GE, REACH, and most
Motorola 1+1 and 2+2 plans. In addition, the ‘any 2-
tone’ feature allows for direct entry of any 2 arbitrary
frequencies to support PLECTRON and other 2-tone
formats without a standardized code plan.
Other Tone Formats: DTMF, Pulse tone (1500 or
2805), 5/6-tone EIA, EUROSIGNAL, ZVEI, DZVEI,
DDZVEI, EEA, NATEL, and MODAT.
Digital Formats: POCSAG 512, 1200, 2400, numeric
or alphanumeric.
10 Flexible Pager Profiles: Allows up to 10 different
pager types in the same system.
User Database: Allows up to 155 names and numbers
to be stored for easy access. Call a pager by name or
number.
Other Features: 10-entry speed dial list. Saved
message list allows 10 ‘canned’ alphanumeric
messages up to 25 characters long to be saved for
instant access. Security feature helps prevent
unauthorized personnel from tampering with the PDE
configuration. Can operate as a local remote control
with optional microphone. Outgoing pages can be
logged to a serial printer or PC with optional cable.
3 INSTALLATION INSTRUCTIONS
Installation Note: Midian products utilize CMOS integrated
circuits, which are susceptible to damage from high static
charges. Be sure to follow standard antistatic procedures
when handling, including using grounded workstations and
soldering irons and wearing grounding bracelets.
3.1 RADIO INTERFACE
Radio Interface connector P1 is an 8-pin
RJ-45 style connector in the center of the
back panel.
+V IN (P1-5) [Red]
The PDE can be powered either by an optional wall
transformer or by the radio power supply. Connect this
wire to the radio power source provided it is between
12 and 15 VDC.
If using a wall transformer, make sure the voltage is
between 12 and 15 VDC and the current rating is at
least 500mA. Also, be certain that positive is
connected to the center pin (inside sleeve).
GROUND (P1-6) [Black]
Connect to radio ground.
AUDIO INPUT/RX IN (P1-8) [Blue]
This connection is only required if you wish to hear
radio audio through the PDE speaker. Connect to a
point in the radio where squelch controlled receive
audio is present at a constant level.
AUDIO OUTPUT/TX OUT (P1-4) [Green]
For tone formats you can usually connect to the mic-hi
input of the radio. The output impedance of the PDE
can be adjusted if necessary by replacing leaded
resistor R81 with an appropriate value. For digital
formats (POCSAG), it may be necessary to connect
directly to the modulator inside the radio.
PTT OUTPUT (P1-3) [Yellow]
This open collector output provides a ground to key-up
the radio when transmitting. If connecting to a relay in
the radio, make sure the coil is bypassed with a diode
to eliminate counter-EMF.
COR INPUT (P1-1) [Gray]
This connection is required only if you desire to
activate the Busy Lockout feature of the PDE. Connect
to a point in the radio squelch or CTCSS circuit that
changes logic level when carrier (or CTCSS) is
detected. A radio whose circuitry provides a logic-low
or logic-high can readily turn Q1 on and off. If only a
high level is provided, it may be necessary to move
R40 from its pull-up to its pull-down position.
MONITOR OUTPUT (P1-7) [Orange]
This output can be used to control the monitor function
of the radio using the <MONITOR> button on the PDE.
This is an open collector output which changes state
each time the <MONITOR> button is pressed.
SQ OUT/LTR IN (P1-2) [Brown]
This wire is not used by the PDE.
3.2 JUMPER SETTINGS
There are two user configurable jumpers, JU1 and
JU4. Both are installed at the factory. JU1 allows
signaling audio to be heard in the local speaker. If this
is not desired, cut JU1.
JU4 controls the output impedance of transmit audio.
See OUTPUT LEVEL below to determine if JU4 will
need to be cut.
3.3 ADJUSTMENTS
Once the unit has been connected to the radio, several
adjustments must be made to achieve proper
operation. It will be necessary to open the unit. Use the
pictorial to identify the location of the following trim
pots: R32 near connector P3, R51 near IC U6, and
R105 near the volume control.

MIDIAN ELECTRONICS INCORPORATED PAGE 5
OUTPUT LEVEL
Use a service monitor to measure the modulation level
generated by the unit. Cause the unit to generate tones
by first pressing <SEND> at the CALL A UNIT prompt
and then typing in 1000010000 and pressing <SEND>.
Adjust R51 so that the modulation level is at 2/3 of the
maximum system modulation (typically 3.3 kHz).
If the output level cannot be adjusted low enough, it will
be necessary to cut JU4. This changes the output from
low impedance to high impedance.
MICROPHONE GAIN
If an optional microphone is installed, the microphone
audio level must be adjusted. Cause the unit to go into
transmit mode by holding down the <SEND> key.
Speak loudly into the microphone at a normal distance.
Adjust R105 such that maximum system modulation is
achieved at peak voice.
SPEAKER PRE-AMP
Though the PDE has a volume control knob, it also has
an input audio pre-amplifier. While listening to audio on
the channel, adjust R32 so that the minimum and
maximum volume control settings are at desired levels.
PRINTER OPTION
With an optional cable, the PDE can log paging activity
to a serial printer or even a PC equipped with a COM
port. The PDE printer port configuration is fixed at 9600
baud, 8 data bits, 1 stop bit, and no parity. To use the
printer, you will have to turn the printer option on in the
CONSOLE SETUP. Next, plug the modular plug of the
cable into P4 (closest to the volume control). You may
need a 9 to 25-pin adapter to connect to your printer. If
you choose to log to a PC, you will need a null modem.
4 OPERATION
4.1 BASIC OPERATION
4.1.1 Navigating the PDE
The PDE starts off at the Main Menu as illustrated
below.
SCROLL INDICATORS – An arrow appearing on
either side of the display indicates more choices are
available by pressing the corresponding <SCROLL>
button.
<SEND> Button – Selects the item shown on the
display. Press <SEND> when CALL A UNIT is
displayed and you will enter Call Mode. In Call Mode,
you will be prompted for CAP code (or a User Name).
As shipped from the factory, you can place a Motorola
general 1+1 page right now by typing a 3-digit CAP
code, followed by <SEND>. If you press <SEND>
without typing in a CAP code, it will act like the PTT
button of the radio.
<#> POUND Button – This button is used any time
you wish to escape the current selection or abort data
entry. Press this key to escape the Call Mode and
return the PDE to the Main Menu. Repeatedly pressing
the <#> button will always return the PDE to the Main
Menu.
4.1.2 Other Controls and Indicators
<MONITOR> - This button always controls the monitor
function of the radio (if monitor output connected).
Press <MONITOR> to toggle the state of the monitor
output to the radio.
POWER / ALARM LED – Glows red when power is
turned on.
TRANSMIT / BUSY LED – This LED is off when there
is no activity. It glows red during transmit. It blinks
green any time the radio channel is busy (provided
COR input is active and connected).
NUMBER Keys – The number keys are used for both
numeric and alphanumeric data entry. They may also
be used as Speed Dial buttons if the feature is
enabled.
<*> STAR Button – Pressing the <*> will toggle the
data entry mode between numeric and alphanumeric
where this is appropriate (such as when entering
POCSAG messages). It can also be used to enter
special DTMF characters *,#,A,B, and C (‘D’ is not
supported).
4.1.3 Data Entry
The PDE supports two modes of data entry: numeric
and alphanumeric. When numeric entry is called for
such as when entering a CAP code, simply press the
appropriate number keys. Alphanumeric entry is called

PAGE 6 MIDIAN ELECTRONICS INCORPORATED
for when entering User Names or messages for
POCSAG alpha pagers.
Entering alphabetic characters using the numeric
keypad is easy. All of the letters of the alphabet appear
above the numbers on the keypad. For example, the
letters ‘A’ ‘B’ and ‘C’ appear on the <2> key.
Alphabetic characters are entered by pressing 2 digits.
The first digit is the key with the desired letter
appearing on it. The 2nd digit is the position of the letter
on that key. For example, the code for the letter ‘C’ is
23 since it is the 3rd letter on the <2> key. The letter ‘T’
is the 1st letter on the <8> key, so its code is 81.
To enter numeric characters in alphanumeric mode,
press the <0> key followed by the desired digit.
Punctuation characters such as comma <,> and <-> do
not appear on the keypad. Special codes have been
assigned to allow entry of those characters. Please
refer to the following chart.
During data entry, the left <SCROLL> button acts as
backspace, and the <#> button aborts data entry. In
some cases, you can use the <*> button to toggle
between numeric and alphanumeric entry (more on this
later on).
A=21 I=43 Q=72 Y=93 7=07 - =15
B=22 J=51 R=73 Z=94 8=08 + =16
C=23 K=52 S=74 1=01 9=09 ] =17
D=31 L=53 T=81 2=02 0=00 * =18
E=32 M=61 U=82 3=03 . =11 / =19
F=33 N=62 V=83 4=04 , =12 Space=10
G=41 O=63 W=91 5=05 ?=13
H=42 P=71 X=92 6=06 [=14
The code 10 is used to insert a space between
characters.
4.1.4 Entering Special DTMF Digits
The PDE supports the following special DTMF 'digits'
in numeric entry mode: *, #, A, B, and C (D is not
supported). These are entered using 2-key sequences
as follows:
* = * * # = * # A = * 1 B = * 2 C = * 3
These special digits can only be entered when adding
a User ID to the database. They cannot be dialed
directly from the call mode (unless the database is
empty). Also, these special sequences should not be
used unless you are using DTMF as the encode
format.
4.2 CALLING AUNIT
4.2.1 Automatic Pager Profile Selection
At this time, you may wish to connect the audio output
(green wire) of the PDE to an amplified speaker so you
can hear the paging tones go out. Select CALL A
UNIT from the Main Menu. Type in 3 digits and press
<SEND>. You should hear a 1 second tone followed by
a 3 second tone. You have just sent a Motorola
General Plan 1+1 page.
Now try typing in a 4-digit number. You should hear
DTMF tones. You may ask, how does the PDE know
which paging format to use? Later on, when there are
entries in the User Database, the PDE will determine
the format based on the information in the database.
Right out of the box, the PDE database is blank so
another method is used.
The PDE picks the Pager Profile automatically based
on the number of digits entered. Enter 3 digits and
profile 3 is chosen. Enter 10 digits and profile 10 is
used. This was done so that the PDE would work right
out of the box. Each of the 10 pager profiles were
initialized at the factory with examples. Try entering 7
digits and you can do a POCSAG page.
4.2.2 Changing Pager Profiles
Say you have pagers that work with Motorola code
plan ‘L’. You can change profile 3 to match this format.
Navigate to SETUP->PAGER SETUP->Profile 3
and press <SEND>. You will first be prompted for a
Profile Name. You can call it whatever you want, let’s
say MOT L:
61 63 81 10 53 <SEND>
Next you will be prompted for pager type. It should
already say ‘2-Tone’, just press <SEND>. Next you
will be prompted for the pager Format. Scroll right until
you find ‘MOTOROLA L’ and press <SEND>. Next you
will be prompted for the 1st and 2nd tone times. They
have already been set for 1000 and 3000 milliseconds
respectively, which is correct for Motorola. Press
<SEND> for each one. You will hear a confirmation
signal. Changes do not take effect until the
confirmation beeps are heard. Now all 3-digit pages
will be in the Motorola L format.
This was just one example of a pager profile. The
information prompted for will be depend on pager type.
For example, a POCSAG pager profile includes a baud
rate setting. Please refer to section 5.5.4, PAGER
SETUP.
4.3 USER DATABASE
The user database makes day-to-day operation of the
PDE much easier. You can use easy-to-remember
names instead of just numbers. It is advised that the
pager profiles be setup before setting up the user
database.

MIDIAN ELECTRONICS INCORPORATED PAGE 7
4.3.1 User Database Features
The primary purpose of the user database is to
associate a name (or alias) with a pager profile and
CAP code. This way, when you go to place a page, the
name of the person can be selected from the
database. The PDE can store up to 155 aliases in its
database. The PDE retains the database memory even
when switched off.
4.3.2 Setting Up the User Database
Begin by compiling a list of names along with the pager
profiles and CAP codes. Give some thought on how
you are going to abbreviate the names since only 14
characters per name are available. To begin entering
data, select Add User from the USERS menu. See the
description of these items in the USERS menu section
5.3 for more information.
4.3.3 Calling a Unit in the Database
To place a call to a unit in the database, first select
CALL A UNIT from the Main Menu. Press the right
<SCROLL> button to display the first user in the
database. Either the CAP code will be displayed, or the
User Name (alias) will be displayed.
This is determined by the Call Entry Mode setting.
Once there are entries in the database, you should
navigate to:
SETUP->CONSOLE SETUP->Call Entry Mode
and change this setting to ALPHA. By doing this, you
will automatically be prompted for a User Name
instead of a CAP code. You can always use the <*>
button to toggle the entry mode between numeric (CAP
code) and alphanumeric (User Name). The <*> button
can also be used to see which CAP code is assigned
to the User Name shown in the display.
In either case, after pressing the right <SCROLL>
button, the left and right scroll indicators will appear on
the bottom line. This indicates that the PDE is in the
Select Mode. Use the <SCROLL> keys to locate the
desired user within the database. When the name is
located, press the <SEND> key to place the call. The
<#> key may be used at any time prior to pressing
<SEND> to cancel the call.
To locate a user in the database more quickly, you can
enter one or more of the first few letters of the User
Name code prior to pressing the right <SCROLL>
button. The PDE will search the database for users
matching the first few letters. You can also do the
same thing in numeric entry mode, but with numbers.
4.4 SPEED DIAL FEATURE
When the speed dial feature is enabled, you can
simply press and hold any of the digits 0-9 for 1.5
seconds to place a call (when in Call Mode only). First,
you must enter each user assigned to a speed dial
button into the database. Then, navigate to
SETUP->SPEED DIAL SET->Speed Dial
And turn the feature on. Next, scroll right and select the
speed dial button you wish to assign to a user. Locate
the user in the database in the same manner as if
placing a call.
4.5 SAVED MESSAGES FEATURE
The PDE can stored up to 10 ‘pre-canned’ messages
of up to 25 characters each for use with POCSAG
paging. See section 5.4 on SAVED MESSAGES for
information on entering the messages. See section
5.1.1 on POCSAG Message Entry for how to recall
saved messages when doing a POCSAG page.
4.6 SECURITY FEATURE
The menu system incorporates a lock feature to
prevent unauthorized personnel from changing the
PDE configuration. The lock feature also serves to
simplify day-to-day operation of the unit.
When the LOCK command is selected, all of the
menus are disabled. The only items available will be
CALL A UNIT and UNLOCK.Selecting UNLOCK
makes all of the menu items available again.
When locked, the unit is password protected so only
authorized personnel may unlock the menus. As
shipped from the factory, the security feature is
disabled and the LOCK/UNLOCK options do not
appear. To enable the feature and select a password,
see the SECURITY SETUP menu item.
Remember your password! Once security is enabled
and the menus are locked, the only way to unlock will
be to use the password. If you do forget the password,
contact Midian for the reset procedure.
5 MENU SYSTEM
The following sections describe the various functions of
the menu system. Factory default settings are
underlined.
5.1 CALL AUNIT COMMAND
Places the unit into Call Mode. All pages are done
from Call Mode. Selecting a unit to call may be done in
several ways.
Speed Dial mode – If speed dial is enabled, simply
press and hold the number key associated with the unit
you wish to call. If the speed dial key continues to be
held after the page is complete, it will serve to keep
PTT asserted for voice-over paging.
For the following four modes, the <SEND> key is
pressed to send the page. If doing voice-over paging,
keep the <SEND> key pressed to hold up PTT.
Direct Numeric Entry mode – Simply key in the CAP

PAGE 8 MIDIAN ELECTRONICS INCORPORATED
Code of the unit you wish to call.
Direct Alphanumeric Entry mode – Key in the User
Name as it appears in the user database.
Numeric Select mode – Press the right <SCROLL>
button to enter select mode. Now you can use both left
and right <SCROLL> buttons to select a CAP code
from the database. Also, you may enter a partial CAP
code prior to pressing right <SCROLL> to find the 1st
entry in the database matching the partial code.
Alphanumeric Select mode – Press the right
<SCROLL> button to enter select mode. Now you can
use both left and right <SCROLL> buttons to select a
CAP code from the database. Also, you may enter a
partial name prior to pressing right <SCROLL> to find
the 1st entry in the database matching the partial name.
Remember, you can use the <*> to toggle between
numeric and alphabetic entry modes. Press <SEND>
to make the call. When sending to a POCSAG pager,
you will then be prompted for a numeric or
alphanumeric message. Entering a message may be
done in several ways.
5.1.1 POCSAG Message Entry
Numeric Entry mode – Simply key in the numeric
message up to 14 digits.
Alphanumeric Entry mode – Key in an alphanumeric
message up to 25 characters.

right <SCROLL> buttons to select a message from the
list of 10 ‘pre-canned’ messages in the Saved
Messages list.
Press <SEND> after message entry to place the page.
Note: Numeric POCSAG pagers can decode the
following special non-numeric characters: space ? U - [
]. Alphanumeric entry mode is required to enter these
special ‘numeric’ characters. Note that the U character
is typically understood to mean ‘urgency’.
Press <#> to escape the Call mode and return to the
Main Menu.
5.2 LOCK OR UNLOCK COMMAND
Note The LOCK and UNLOCK menu options do not
appear unless enabled in SECURITY SETUP.
Selecting LOCK will disable access to the parts of the

be prompted to fill in the information for that user such
as User Name and CAP Code. See EDIT USER for
more information.
5.3.2 Delete User menu
Allows you to delete a user record from the database.
When DELETE USER is selected, you will be able to
select the user you wish to delete in the same manner
as if placing a call to a unit. Use the scroll buttons to
find the user you wish to delete. Press <SEND> to
delete the selected user. You will have to press
<SEND> a second time to confirm. Press <#> to
cancel if you change your mind.
5.3.3 EDIT USER menu
Allows you to change information about a user. Select
the user you wish to edit in the same manner is if
placing a call to that user. Use the scroll buttons to find

5.5.5.1 Keyup Delay setting
This sets the Key-Up Delay, also known as Front
Porch Time. This is the amount of time the PDE will
wait after asserting PTT before sending tones over the
air. This time allows for delays introduced by repeaters
and decoding of squelch control signals such as
CTCSS.
Range: 01 to 99 * 100 milliseconds
Default: 04 * 100 milliseconds
5.5.5.2 COR Polarity setting
Note: If not using the Busy Lockout feature, you may
leave the COR input unconnected.
The COR input is used in conjunction with the Busy
Lockout feature. Change this setting to match the
state of the COR (carrier detect) input when the radio
channel is busy.
LOW Channel is busy when COR is 0V.
HIGH Channel is busy when COR is 5V.
5.5.5.3 Busy Lockout feature
This feature prevents the PDE from transmitting on a
busy channel. If this feature is ON, the unit will not
transmit when the COR input is in the active state.
When making a call and the channel is busy, the PDE
will wait until the channel is clear and then transmit.
New calls cannot be placed until the pending call is
completed or canceled. When this option is OFF, the
unit will transmit regardless of the state of the COR
input.
OFF Transmit regardless of COR input.
ON Do not transmit when channel busy.
5.5.6 SECURITY SETUP menu
5.5.6.1 Security setting
Allows the security option to be turned on and off. If
turned off, the LOCK/UNLOCK menus will not appear.
OFF Disable security feature.
ON Enable security feature.
5.5.6.2 Password setting
Sets the password required to UNLOCK the menu
system when the Security is turned on. Must be 4
numeric digits.
Range: 4 digits
Default: 0000
5.5.7 UTILITIES menu
5.5.7.1 Reset Defaults
This will reset all the parameters listed above to the
factory default settings. The contents of the user
database will not be affected.
5.5.7.2 Clear Database
This will completely clear the user database. The
contents of the other parameters listed above will not
be affected.
5.5.7.3 Factory Debug
This is used by the factory for product testing. Do not
select this function unless directed to do so by
Midian Technical Support.
6 APPENDIX
6.1 SYSTEM ERROR MESSAGES
CHANNEL BUSY
Reason: An attempt was made to transmit or make a
call on a busy channel with busy lockout enabled.
Solution: Wait until the channel is clear before
transmitting.
DATABASE EMPTY
Reason: An attempt was made to edit or delete a user

PAGE 14 MIDIAN ELECTRONICS INCORPORATED
when the database was empty.
Solution: These functions do not apply when the
database is empty.
DATABASE FULL
Reason: An attempt was made to add a user to the
database and there is no more room. The maximum
number of user aliases of 155 cannot be exceeded.
Solution: Remove any old user names that are no
longer in service. If this is not possible, contact Midian
for possible alternative products.
DATABASE ERROR
Reason: One or more entries in the user database has
been corrupted. This can happen if power is lost at the
exact time the database is being updated. Any
corrupted records will be blanked-out and must be re-
entered.
Solution: Cycle power to the unit. This should clear the
error. If the error message continues to come up,
contact Midian technical support.
DUPLICATE NAME
Reason: An attempt was made to add a user name to
the database which is already in the database. Each
user name in the database must be unique.
Solution: Choose a unique user name for each user. If
it is necessary to edit the user record, use the edit
menu.
EE CHKSUM ERR
Reason: The configuration settings stored in EEPROM
have been corrupted. This can happen if power is lost
at the exact time a parameter is being updated. All
configuration settings will be set back to defaults. The
user database should not be affected.
Solution: Cycle power to the unit. This should clear the
error. If the error message continues to come up,
contact Midian technical support.
EE WRITE FAIL
Reason: The EEPROM chip or connections to it have
failed.
Solution: Contact Midian for instructions on getting the
unit repaired.
ENCODER TIMEOUT
Reason: The PDE expects a page to be completed
within 20 seconds and this time has been exceeded.
This can happen in the if the total time of the key-up
delay and encoding exceeds 20 seconds. This is not
likely to happen unless non-standard encode timings
and encode lengths are used. It is also possible that
there could be a hardware failure.
Solution: If total time of the key-up delay and signaling
tones exceeds 20 seconds, simply press <SEND> to
clear the message from the display. The page will still
be sent. In the event of a hardware failure, contact
Midian technical support to determine if that is the
cause.
INVALID CAP CODE
Reason: The number of digits in the CAP code are
incorrect for the pager format being used.
Solution: Enter the correct number of digits. Most built-
in 2-tone formats require exactly 3 digits. POCSAG
requires 7 digits, and ‘any 2-tone’ requires 10 digits.
The other formats can accept 1-10 digits.
NOT FOUND
Reason: There is no entry in the user database that
matches the data entered.
Solution: When selecting a user to call, the name or
the CAP code can be entered in whole or in part. When
entering a partial name or CAP code, press the right
<SCROLL> button to search the database for the first
partial match. Press <SEND> only if the whole CAP
code or name has been entered. There may be no
entry in the database that matches in whole or in part.
In that case, the user must be added to the database.
NOT NUMERIC MESSAGE
Reason: You are trying to send a message containing
non-numeric characters (other than those below) to a
POCSAG pager designated as being numeric only.
Solution: Restrict your entry to POCSAG ‘numeric’
characters only. These are 0123456789?U-][ and
space.
PROFILE IN USE
Reason: You have selected a pager profile to edit that
is associated with a user in the database. This
message is provided as a warning so that you do not
change a user’s profile unintentionally.
Solution: You may either press <#> to cancel your
selection, or press <SEND> to proceed to view or edit
the selected profile. Changing an already assigned
profile may cause problems if the profile changes, say,
from POCSAG to 2-Tone because 2-Tone users
cannot have 7-digit CAP codes! Please keep this in
mind if you proceed to do this.

MIDIAN ELECTRONICS INCORPORATED PAGE 15
SPEED DIAL EMPTY
Reason: You have pressed a speed dial number, but
there is no user associated with it. The user may have
been deleted, or no association was ever made.
Solution: Go to speed dial setup and associate a user
in the database to the speed dial number.
6.2 TONE CHARTS
