GENERAL INFORMATION

Midian’s PR-10i 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-10i can be connected to a simplex mobile or base station to create a simplex store and forward repeater.

When the PR-10i 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-10i will key the radio and retransmit the

recorded audio. The following are applications for the PR-10i 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-10i 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-10i has a tone decoder on the board that can be programmed to decode any 2 tones (up to 4 different

sets of tones). When the tone decoder decodes the programmed sequence(s) it will give a validate output to the

PR-10i. The validate confirms to the PR-10i that the PR-10i should repeat the incoming audio. The tones will also

be retransmitted. The following are applications for the PR-10i as a selective simplex repeater:

• Retransmit 2-tone pages for fire departments into remote areas or buildings with poor coverage.

Note: If formats other than any 2 tones need to be decoded please see your salesperson. DTMF, 5-Tone or Pulse

Tone (1500 Hz or 2805 Hz for HEAR Systems) can be added as an option.

Announcement Mode:

The PR-10i 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)

Features:

• Up to 180 seconds of record time for message playback

• C R or V X operation

• Supports 2-Tone

• DTMF, 5-Tone and Pulse Tone decoding for validating and regenerating paging are available as an option,

please specify this when placing an order.

Benefits:

• Low cost alternative for expanding radio coverage

• Existing licenses can be used

• Low cost alternative for testing radio coverage

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-10i. 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-10i to retransmit the page. The PR-10i has its

own internal validation using 2-Tone, DTMF, 5-Tone or Pulse Tone signaling.

J3- : 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 C R is inactive and off when it is active.

J3-6: External Power (Green): Connect to a 13-18 VDC source in the base station radio. If power cannot be

connected to the radio use the optional wall adaptor (13-18 VDC). Midian recommends using the power from

either radio, or from our AC adaptor. Use of any other power source may void the warranty.

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.

PRODUCT PROGRAMMING

The PR-10i 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

KL4-F USB PORT ASSIGNMENT and SOFTWARE INSTALLATION

Go to our website midians.com and under downloads> software down load the latest MPS software version. If

using the supplied CD-R M insert it into the PC’s CD-R M drive. In the browser that will pop-up, install the MPS

programming software. Be certain that the “Install KL-4 USB Driver” box is checked during the installation

process.

pen Windows’ Control Panel and go to Device Manager.

pen Ports (C M& LPT) to identify the port assignment issued by computer. Plug in the KL4 programmer to the

USB port and the screen will flash and show the device location.

pen the software and choose product from product tree then set appropriate comport selection in the MPS

software as needed This must be done for both the PR10 and PR10 Tone Decoder selections.

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-10i. The PR-10i dos not receive power from the KL-4F it must

be powered from the radio or the AC adaptor.

To program the PR-10i, turn power onto the PR-10i and within 15 seconds click “Program Unit” in the menu bar to

send the file to the unit. Follow the same procedure to read the unit, but select “Read Unit” in the menu bar.

General Info Tab:

Unit Information

This information area is updated when a unit is read or programmed. It will also be updated when a data file is

loaded from a previous unit read and then saved. Below is a summary of the fields:

Product - Shows a more detailed description of the product model within the series.

uP #1 Firmware Version - Indicates the reported Firmware Version of the microcontroller of this product.

uP #1 Loader Version - Indicates the reported Loader Version of the microcontroller of this product.

General Settings Tab:

Store on COR/Store on VOX: Select the appropriate method that the PR-10i should use to start recording

incoming audio.

COR

Hold-Up Time This sets the amount of time after a loss of C R or V X that the unit will wait until it retransmits

the recorded audio.

VOX

Sensitivity: This is a threshold detection based on the energy level in the audio.

Attack Time: This sets the minimum time before the PR-10i will detect V X based on the sensitivity setting.

Decay Time: This sets the time before the PR-10i will drop the V X detection. Be certain to set this long enough

so that you do not have drop outs between words or on brief pauses.

Beep Options

Power Up : Enables a short beep sequence that takes place immediately after power-up.

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-10i can store up to a 2.25 minute voice message. If checked the

PR-10i can store up to a 3 minute voice message, but with a lower level of audio quality.

Signaling Tab

Note – This is a new TAB for the PR-10i. The PR-10i uses a 2- tone decoder that is built-in to the unit. That

decoder is progra ed using this TAB. The previous version of this device is the PR-10. The PR-10 used

a tone decoder odule that required a 2nd progra ing interface specifically for the decoder. That 2

progra ing interface does not apply to the PR-10i

Decode Settings

Decode Tone A Time: The amount of time the first tone (A-tone) of a sequence must be present before it is

decoded. This should be between 1/2 and 1/6th of the encode time and greater than the Tone Loss Time. For a

1-second A-tone, the suggested value is 400 milliseconds.

Decode Tone B Time:

The amount of time the 2nd tone (B-tone) of a sequence must be present before it is decoded. This should be

between 1/2 and 1/6th of the encode time and greater than the Tone Loss Time. For a 3-second B-tone, the

suggested value is 600 milliseconds.

Decode Group Tone Time:

The amount of time a single tone must be present before it is considered a group call. This should be between

1/2 and 1/6th of the encode time and greater than the Tone Loss Time. For an 8-second tone, the suggested

value is 4.0 seconds.

Tone Loss Time:

The amount of time the absence of tone will be permitted before the decoder is reset. This should be less than

the shortest of the A-tone Decode Time and B-tone Decode Time. If the shortest decode time is 400 ms, the

suggested loss time is 200 ms. Some tone formats specify a gap time between tones. If using such a format, the

loss time must exceed the gap time.

Decode Sequences

Number of Decodes: This is the number of decode sequences that are enabled and the device is capable of

decoding.

A-tone Frequency

The frequency of the first tone (A-tone) of the sequence in Hz.

B-tone Frequency

The frequency of the second tone (B-tone) of the sequence in Hz.

Retransmit Settings Tab:

Key-Up Delay: This sets the amount of time the PR-10i 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-10i to hold off

regenerating the recorded audio until the PR-10i has received a channel acquisition acknowledgement from the

base station radio.

Validation Required for Retransmit: If checked the PR-10i will only retransmit messages once it has received a

logic low from the internal tone decoder.

Number of Retransmits: This sets how many times the PR-10i will retransmit the last recorded audio clip. If set

to zero the PR-10i 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.
