6BGENERAL INFORMATION
Midian’s PR-10 is a simplex store and forward repeater (aka simplexor or parrot) and paging regenerator that
supports retransmitting of both tone and voice similar to the discontinued Zetron Model 19.
Simplex Repeater Mode:
The PR-10 can be connected to a simplex mobile or base station to create a simplex store and forward repeater.
When the PR-10 sees a busy indication from the connected radio it will start recording the received audio. When
the busy indication goes away for a programmed amount of time, the PR-10 will key the radio and retransmit the
recorded audio. The following are applications for the PR-10 as a simplex repeater:
Expand radio coverage into remote locations, valleys, tunnels, buildings (hospitals, campuses, etc),
downtown areas and more.
Evaluate potential radio site or coverage problems by connecting the PR-10 to a mobile radio. A technician
can then drive through the desired coverage area, key up and transmit voice, unkey and listen to the repeated
audio quality.
Selective Repeat Mode:
The PR-10 has a tone decoder on the board that can be programmed to decode 2-Tone, DTMF, 5-Tone (must be
ordered for 5-Tone operation) or Pulse Tone (1500 Hz or 2805 Hz for HEAR Systems). When the tone decoder
decodes the programmed sequence(s) it will give a validate output to the PR-10. The validate confirms to the PR-
10 that the PR-10 should repeat the incoming audio. The tones will also be retransmitted. The following are
applications for the PR-10 as a selective simplex repeater:
Retransmit 2-tone or DTMF pages for fire departments into remote areas or buildings with poor coverage.
Retransmit Pulse Tone pages from ambulances in remote areas with poor coverage to hospitals (HEAR
Systems).
Announcement Mode:
The PR-10 can be programmed to repeat the last received audio message continuously at programmable
intervals, applications include:
Broadcasts for road or weather conditions
Aviation authority broadcasts for pilot information (ATIS – Automatic Terminal Information Service)
PR-10 Features:
Up to 180 seconds of record time for message playback
COR or VOX operation
Supports 2-Tone, DTMF, 5-Tone (must be ordered for 5-Tone operation) and Pulse Tone decoding for
validating and regenerating paging
PR-10 Benefits:
Low cost alternative for expanding radio coverage
Existing licenses can be used

HARDWARE INSTALLATION
Be certain to follow standard anti-static procedures when handling any of Midian’s products.
Use the enclosed matching cables with RJ45 type connectors to plug into the PR-10. The other ends can be
connected to the appropriate type of radio connector using the pin out and color codes show below. See
connector pin out in the chart below.
Midian offers several pre-made cables for plug and play operation for certain radios. Contact sales for further
information.
J3-1: Validate (Brown): This is an external validation for the PR-10 to retransmit the page. The PR-10 has its
own internal validation using 2-Tone, DTMF, 5-Tone or Pulse Tone signaling.
J3-2: External Enable (Blue): If using a second radio as the transmitter, this input is used as a busy channel
lockout feature. Connect to a point in the radio’s squelch or CTCSS circuit that changes logic level when a carrier
is detected.
J3-3: Mic audio (White): Connect to the MIC-High in the base station radio.
J3-4: Ground (Black): Connect to ground in the base station radio.
J3-5: COR Input (Red): Connect to a point in the radio’s squelch or CTCSS circuit that changes logic level when
a carrier is detected. The unit defaults to look for an active low. If programmed for an active high the LED will be
on when COR is inactive and off when it is active.
J3-6: External Power (Green): Connect to a 12-18 VDC source in the base station radio. If power cannot be
connected to the radio use the optional wall adaptor (12-18 VDC).
J3-7: PTT Output (Yellow): This open collector provides a ground during PTT. Connect this to the PTT of the
base station radio.
J3-8: Speaker – (Violet): Connect to Speaker - of the base station radio. If the speaker uses a common ground
do not connect the Violet wire.
J3-9: Speaker + or Single Ended Speaker High (Orange): Connect to Speaker + of the base station radio.
J3-10: Trunking Delay (Gray): Connect this to a point in the base station that gives a change of state when a
channel is acquired. The unit defaults to look for an active low. If programmed for an active high the LED will be
on when the trunk delay is inactive and off when it is active.

1BPRODUCT PROGRAMMING
Jumper Settings:
The following table shows the default jumper settings and their function:
Jumper Default Description
JP1 Out Ground for PTT Input on Tone Decoder. Install for Tone Decoder programming and
remove when completed
JP2 In Future Use
JP11 Out Radio Output Audio Impedance (In = 1 K Ohm - Out = 47 K Ohm)
Programming:
The PR-10 is programmed using Midian’s KL-4F and KL-4F-PC1 programming cable and the MPS software.
Please reference the KL-4F manual for programming cable and software setup. Note that when programming the
PR-10 there are 2 programming files that need to be downloaded to the unit when using the selective repeat
capabilities, the PR-10 and PR-10 Tone Decoder files from the programming software product selection tree.
Set the parameters of the software to fit the application. If any clarifications on a feature are required, move the
mouse cursor over the feature name until the question mark appears and right click, a definition of the feature will
be shown.
After entering the parameters, save the file by going to File - Save As. Enter the file name in the File Name block
and click Save. Saving the file will allow for quick and easy reprogramming of units.
Plug the KL-4F-PC1 into the programming jack on the unit and into the P10 connector on the KL-4F. Insert the
3.5 mm stereo plug into the J8 connector on the PR-10.
To program the PR-10, turn power onto the PR-10, push and hold the power button on the KL-4F, and within 15
seconds click “Program Unit” in the menu bar to send the file to the unit. The LED on the interface will flash
indicating programming is complete. Follow the same procedure to read the unit, but select “Read Unit” in the
menu bar. When reading the unit, the LED on the interface will not flash. Cycle power after programming.
When programming the tone decoder, verify the communication port selection is properly set and then install JP1
while the power off. Apply power and the tone decoder must have the file sent to the unit within 5 seconds of
powering the unit. Remove JP1 after programming the tone decoder. Cycle power after programming.

General Settings Tab:
Store on COR/Store on VOX: Select the appropriate method that the PR-10 should use to start recording
incoming audio.
COR Hold-Up Time This sets the amount of times after a loss of COR or VOX that the unit will wait until it
retransmits the recorded audio.
VOX Settings > Sensitivity: This is a threshold detection based on the energy level in the audio.
VOX Settings > Attack Time: This sets the minimum time before the PR-10 will detect VOX based on the
sensitivity setting.
VOX Settings > Decay Time: This sets the time before the PR-10 will drop the VOX detection. Be certain to set
this long enough so that you do not have drop outs between words or on brief pauses.
Beep Options > Courtesy Beep: If selected, once the unit is done retransmitting the recorded audio it will
generate a courtesy tone to let others know it is done retransmitting.
Voice Compression: If left unchecked the PR-10 can store up to a 3-minute voice message. If checked the PR-
10 can store up to a 2.25 minute voice message, but with a higher level of audio quality.
8
Retransmit Settings Tab:
Key-Up Delay: This sets the amount of time the PR-10 waits after keying the base station radio before it starts to
retransmit the recorded audio.
Trunking Delay Enable: Check this box if using a trunking system. This will cause the PR-10 to hold off
regenerating the recorded audio until the PR-10 has received a channel acquisition acknowledgement from the
base station radio.
Validation Required for Retransmit: If checked the PR-10 will only retransmit messages once it has received a
logic low from the internal tone decoder or from an external source.
Number of Retransmits: This sets how many times the PR-10 will retransmit the last recorded audio clip. If set
to zero the PR-10 will continuously retransmit the last recorded message based on the retransmit interval until a
new message is received. This is used for Announcement Mode.
Retransmit Interval: This sets the time interval between the retransmits set in the Number of Retransmits field.

Basic Inputs Tab:
COR > Active Polarity: This sets whether the PR-10 looks for an active low or active high to start recording the
received audio. Note: The associated COR LED, when programmed for an active low, will be off when COR is
inactive and on when COR is active. However, the COR LED, when programmed for an active high, will be on
when COR is inactive and off when COR is active.
COR > Debounce: If checked the PR-10 will require a continuous active state for 40 msec before accepting the
COR.
Basic Outputs Tab:
PTT > Active Polarity: This sets whether the PR-10 gives an active low or active high to key the connected radio.
10
Aux Inputs Tab:
Validation Input > Active Polarity: This sets whether the PR-10 looks for an active low or active high to validate
a decode from the internal tone decoder or an external validate. Note: The internal tone decoder uses an active
low polarity.
Validation Input > Debounce: If checked the PR-10 will require a continuous active state for 40 msec before
accepting the validation.
Trunking Delay Input > Active Polarity: This sets whether the PR-10 needs an active low or active high
indication from the radio to indicate a trunked channel has been established. Note: The associated Ch. Acq. LED,
when programmed for an active low, will be off when trunking input is inactive and on when trunking input is
active. However, the Ch. Acq. LED, when programmed for an active high, will be on when trunking input is
inactive and off when trunking input is active.
Trunking Delay Input > Debounce: If checked the PR-10 will require a continuous active state for 40 msec
before accepting the channel acquisition.
