GENERAL INFORMATION

Midian’s GPS speaker microphones encode a user’s GPS coordinates along with the user’s ANI and Emergency
ANI to display on Midian’s CAD-800 or CAD-800U base station controllers. The following is a list of benefits
provided by Midian’s GPS systems:

 Allows dispatchers to know who he or she is talking to.
 Identify system abusers.
 Identify emergency conditions.
 Assign calls fairly.
 Track user location.

Midian’s SM1G series encodes ANI and Emergency ANI along with Midian’s GPS location reporting to Midian’s
CAD-800 or CAD-800U which uses a Google Earth interface to display the unit’s location on a map.

The SM1G series also offers Man-Down and Lone Worker features. If the unit does not detect movement (Man­Down) or receive any user interaction (PTT or Lone Worker Reset button) for a programmable period of time the
unit can key the radio and send the Emergency ANI.

In addition to the above encoding features, Midian’s GPS speaker mics can decode commands from the CAD-800
such as Polling, Selective Calling, Radio Disable, Radio Enable, Spy (Remote Monitoring) and Emergency
Acknowledge. Polling allows the dispatcher to request a unit’s GPS location. Selective calling can be to call an
individual unit, a group of units or all units. If a unit becomes lost or stolen, it can be disabled, so it cannot
interfere with the system. If the unit is later recovered the unit can be re-enabled. The Spy function enables the
dispatcher to eavesdrop on a unit during an emergency or other condition. If multiple Emergency IDs are
transmitted, the dispatcher can stop subsequent Emergency ID transmissions using the Emergency Acknowledge
feature.

VS-1200:

The VS-1200 is a Digital Signal Processor (DSP) based Frequency Domain voice scrambler offering a high level
of voice privacy. The DSP converts the analog signal into quantitized digital data. It then converts the “Time
Domain” signal into the “Frequency Domain”. This results in an audio “frequency spectrum”, which is then
partitioned into bins that are encrypted by the non-linear key generator. The digitized data is converted back to
the analog realm using a digital to analog converter.

The above technique and the lack of synchronization result in excellent audio quality, high security and enable the
VS-1200 to be used in virtually any type of radio system. These systems include HF SSB, Conventional Two­Way, Trunking, Voting and Simulcast.

VS-115:

Midian’s VS-115 is a rolling double inversion scrambler that offers 1020 possible codes (4 groups with 255 codes
per group). Of these codes the scrambler may be programmed with up to 4 of these codes. The VS-110 series is
compatible with Icom’s UT-110.

VS-1150:

Midian’s VS-1150 is a double inversion scrambler (aka split-band scrambler) that offers 32 possible codes. Of
these 32 codes the scrambler may be programmed with up to 4 of these codes. The VS-1150 series is compatible
with Midian’s VPU-6, Icom’s UT-109 or Inysa’s XPTO.

VS-1050:
Midian’s VS-1050 is a voice inversion scrambler that provides up to 4 different inversion frequencies that are

button selectable. The programmable inversion frequency range is from 2100 Hz to 4096 Hz and provides
compatibility with Midian’s VPU series voice inversion scramblers, as well as other industry inversion scramblers.

HARDWARE INSTALLATION

Be certain to follow standard anti-static procedures when handling any of Midian’s products.
For all diode protected inputs (i.e. PTT Input, Mode Input, COR Input) the voltage level to be required for a logic

low is less than 0.5 V and a logic high requires at least 2.1 V.

J1 – RJ-48 10-Pin Connector:
J1:1 – Program In: The KL-4 Option B or KL-4F-PC2 must be plugged in to access this pin for programming.
J1:2 – PL DIS: Hook switch for mobile radio applications.
J1:3 – MIC: Connect to the MIC+ connection on the radio’s external mic connector
J1:4 – Ground: Connect to a ground connection on the radio’s exte rnal mic connector.
J1:5 – COR/LTR: Future use.
J1:6– B+ (+3.5-8.0 VDC): This connection is only needed if not using the internal battery of the SM1. Connect to

B+ (3.5-8.0 VDC) connection on the radio’s external mic connector. If connecting to a mobile this must be
specified when ordering or you must install a 6.2 V Zener diode at D1 if the voltage is higher than 9.7 V. Connect
to a regulated voltage point in a vehicular radio if engine noise is present on the battery line. With D1 installed, the
voltage input could be as high as 15 VDC (nominal is 13.5 VDC). R-5 O Ohm resistor must be installed. Note: If
connecting this input DO NOT install the battery into the microphone and U1 must be removed.

J1:7 – PTT: Connect to a PTT connection on the radio’s external mic connector used to key the radio. Some
radios look for a resistance on the microphone input to trigger PTT, R-50 in the SM-1 is used for this purpose and
will need to be picked on an individual radio basis. For Vertex radios this should be a 2.7 K resistor.

J1:8 – SPK Ground (SPK-): If connecting to a radio with a double ended speaker, then connect this line to the
negative side of the speaker connection on the external mic connector. If connecting to a radio with a single
ended speaker, this line is not connected.

J1:9 – SPK Hi (SPK+): Connect this line to the positive side of the speaker connection on the external mic
connector.

J1:10 – Program Out: The KL-4 Option B or KL-4F-PC2 must be plugged in to access this pin for programming.
J2 – 3.5 mm Stereo Connector:

The 3.5 mm stereo connector on the SM1 is a dual purpose connector; charging and audio. The tip is 6V for
charging, ring is Speaker + and sleeve is ground. Use only Midian supplied wall power adaptors and audio
accessories for use with the SM1.

Charging: To charge the unit, plug the Midian supplied wall power adaptor into an outlet and then plug the 3.5
mm plug into the 3.5 connector on the unit. When the LED is glowing green the unit is charging. When the LED
goes out then it is done charging. When the unit is in need of a charge the unit will emit a descending series of
tones to indicate low battery. Only use Midian provided accessories for charging.

Audio: The 3.5 mm connector can be used as an audio accessory port (i.e. ear bud). The connections should be
ring as Speaker + and Sleeve as ground. Not using a Midian supplied audio accessory could result in damage to
the unit.

PRODUCT PROGRAMMING

Midian’s SM-1 products are programmed via Midian’s KL-4F and KL-4F-PC2 or the KL-4 and KL-4 Option B, as
well as the MPS software. Please reference the KL-4 manual for setup instructions of the programming software
and hardware. From the product selection screen in the software, select the desired SM1G model from the list
and click OK.

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.

If using the KL-4F, plug the KL-4F-PC2 cable from the KL-4F’s RJ-11 connector (P10) into the RJ-48 connector
on the SM1.

If using the KL-4, plug the KL-4 Option B cable from the KL-4 connector labeled “P4 VPU-12A” into the RJ-48
connector on the SM1.

Push the power button on the KL-4F or KL-4 and within 15 seconds select Program Unit or Read Unit in the
software. Upon power up the unit will be awake for 15 seconds before going into Power Save mode.

After programming or reading the unit, turn off the unit for 3 seconds and then turn back on.

Wake on COR/Wake on VOX: Select the appropriate method that the unit should use to come out of power save.
Note: Most portables do not provide COR detection on the speaker mic port, so it will be necessary to use VOX
detection.

COR Hold-Up Time This is the amount of time after loss of COR/VOX that the unit considers COR/VOX dropped.
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 unit will detect VOX.
VOX Settings > Decay Time: This sets the time before the unit 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 > Power Up: Enables a short beep sequence that takes place immediately after po wer-up.
Beep Options > Error: This beep may be triggered by any input event if programmed to do so. For example, if a

long press on the Mode Input is not assigned to a function, it may be configured to generate the error beep. If
there is a failure of the GPS module, then about 20 seconds after power up the error beep will be heard.

Beep Options > Mode: This is used to indicate to the user when the mode has been enabled/disabled (i.e. Lone
Worker enabled).

Beep Options > Go Ahead: This is a local beep out the speaker to indicate to the user that ANI has been sent
and it is okay to talk.

Beep Options > Wake Up Beep: Enables a short beep to be sent over the air after PTT is pressed. Enabling this
beep is recommended when the 'Wake on VOX' feature is used.

Beep Options > Courtesy Beep: If selected, once the PTT button is released, the unit will generate a courtesy
tone to let others know it is done transmitting.

Beep Options > Enable Side Tone Pin: Future Use.

7

Trunking Delay Enable: Check this box if using a trunking system. This will cause the unit to hold off transmitting
the ANI until it has received a channel acquisition acknowledgement from the radio. This field is not used with
portable radios.

Key-Up Delay: This sets the amount of time the unit waits after keying the radio before it transmits the ANI.
CAD Settings:
System ID: Set this field to the same value as the System ID programmed into the CAD-800 or CAD-800U. Only

a CAD-800 with the same System ID can decode the GPS location information from the GPS speaker mic. This
field is a six character field that supports 000000-FFFFFF (0-9 & A-F) for a total of 16,777,216 possible System
IDs.

Restore System ID To Default: Pressing this button will return the System ID to Midian’s default System ID of
4D6964.

Group ID: This sets the group number that the unit is a part of. The Group ID is a 3 character field that supports
000-FFF (0-9 & A-F) for a total of 4096 groups.

Individual ID: This sets the unit’s identification number. The Individual ID is a 5 character field that supports
00000-FFFFF (0-9 & A-F) for a total of 1,048,576 unit IDs per group. Between all groups and unit IDs the total
number of supported IDs by the system is 4,294,967,296.

Enable CAD Decode: Checking this box enables Midian’s FMP signaling features such as Polling, Radio
Disable, Radio Enable, Selective Calling, Remote Monitoring and Emergency Acknowledge.

Polite Transpond: If the unit is required to transpond in response to a command from the CAD-800, it will do so
immediately after receiving the command. Checking this box will cause the unit to check for a busy channel
indication (using VOX or COR) before transponding. If the channel is busy, the transpond will be postponed until
the channel is no longer busy.

Spy Duration: When a Spy command (remote monitoring) is received from the CAD-800, this sets the amount of
time that the speaker mic will key-up the radio and transmit audio from the microphone.

Number of Rings: This sets the number of times the speaker microphone will ring when it receives a selective
call before timing out.

8

GPS Enable: Check this button to enable the GPS or GLONASS features of the product.
GNSS: Select which Global Navigation Satellite System (GNSS) is being used GPS or GLONASS. GPS is the

United States’ form of GNSS. GLONASS is Russia’s form of GNSS. GLONASS is currently in development.
Please contact Midian for the availability of GLONASS in the GPS speaker microphone.

Beep Upon First Fix: If checked, the GPS speaker microphone will give a double beep once the GPS speaker
microphone has acquired a location fix. The time to acquire a fix is dependent upon various conditions such as
terrain, buildings, weather, etc. Under ideal conditions this time could be as fast as 30 seconds. A first fix
acquisition time of 2-3 minutes would not be abnormal under other conditions.

GPS Power Save Enable: Checking this box will help extend battery life by placing the GPS receiver in a low
power or “sleep” state for 30 seconds in between position fixes. Upon waking, the GPS receiver is left on at full
power until two valid position fixes are determined and then once again is placed in sleep mode. Under good
signal conditions it takes about 20 seconds for the GPS receiver to acquire new fixes after waking. Therefore one
can expect a new fix to be determined about once per minute, though this cannot be guaranteed.

9

Signaling Position Settings: Leading and trailing signaling types (ANI, FMP and FMP w/GPS) can be selected
here. For example MDC-1200 can be sent on the leading edge and Midian’s FMP with GPS can be sent on the
trailing edge.

ANI: The ANI specified in this selection is not the typical FMP ID used by Midian’s GPS speaker mics. Instead
this refers to ANI formats such as MDC-1200, FleetSync, DTMF, 5-Tone or GE-Star. One of these formats can be
selected to send a pre-ANI or post-ANI.

FMP: This refers to Midian’s signaling protocol used in the GPS speaker microphone minus the GPS location
information.

FMP w/GPS: This refers to Midian’s signaling protocol used in the GPS speaker microphone including the GPS
location information.

Protocol Format: Select the desired signaling format in which the ANI and ENI will be transmitted.
Tone Duration: This field only applies to DTMF and 5-Tone formats and sets the length of each tone.
Tone Gap Duration: This field only applies to DTMF and sets the length of the gap between tones.
Fleet ID: This field only applies to FleetSync and sets the Fleet ID of the unit.
Unit ID: This sets the non-FMP ANI of the unit.
Message: This field only applies to G-Star.
Status: This field only applies to G-Star.
Repeat Delay: This sets the time after sending an ANI that the unit will wait before sending another ANI.

10

FMP: This refers to Midian’s signaling protocol used in the GPS speaker microphone minus the GPS location
information.

FMP w/GPS: This refers to Midian’s signaling protocol used in the GPS speaker microphone including the GPS
location information.

Protocol Format: This displays the format selected on the ANI tab.
Fleet ID: This field only applies to FleetSync and sets the Fleet ID for the ENI.
Unit ID: This sets the Emergency ANI of the unit.
Message: This field only applies to G-Star.
Status: This field only applies to G-Star.
Transmit Forever: If selected the ENI will transmit continuously at the repeat interval until canceled.
Busy Lockout: When it is time to transmit the ENI, if this box is not checked the transmission will take place

regardless of whether or not the channel is busy. If this box is checked and the channel is busy (as indicated by
COR or VOX), the ENI will not be transmitted. Instead the unit will wait 2.3 seconds and then check again to see if
the channel is busy. If the channel is not busy at that time, the ENI will be transmitted. If, not the process will
repeat indefinitely.

Transmit Count: This sets the number of times the ENI will be sent.
Repeat Interval: This sets the time between ENI transmissions.
PTT Resets/Cancels ENI: If selected, pressing the PTT button will either reset the Lone Worker’s Transmit Delay

time or cancel the transmission of the ENI.

Live Mic Enable: If selected the unit will enable the mic of the radio to transmit mic audio to the dispatcher.
Revert to Clear: This will switch the TX mode to Clear when using Live Mic.
Locator Tone Enable: If selected the unit will emit tones out the speaker after all Emergency ANI’s have been

sent. This feature is not available if Transmit Forever is checked.

11

Transmit Delay: In Lone Worker mode, if the user does not interact with the radio before this amount of time
passes, the ENI sequence will be transmitted. This time is in seconds.

Warning Tone Enable: This will generate a tone sequence to alert the user the ENI is about to be transmitted.
Warning Tone Delay: In Lone Worker mode, if the user does not interact with the radio before this amount of

time passes, the emergency warning tone will be sounded. This amount of time must be less than that of the
Transmit Delay for the warning tone to be sounded. Also, the Warning Tone Enable box must be checked for the
tone to be sounded. For example, based on the screen shown above after 105 seconds of no activity the unit will
generate warning tones. The user then has 15 seconds (120 minus 105) to interact with the radio to keep the
Transmit Delay time of 120 seconds from expiring and the ENI being transmitted.

Continuous Warning Enable: This will generate a constant tone to alert the user the ENI is about to be
transmitted.

Power-up with Lone Worker on: If checked the unit will be in Lone Worker mode when the radio is turned on.
This eliminates the need for the user to use the mode input to turn the Lone Worker mode on.

Motion Resets Delay Timers: The unit can use the accelerometer to detect motion based on the Motion
Sensitivity setting to determine if the user is in distress in addition to requiring interaction with the radio.

Motion Sensitivity: This sets a level of motion required to reset the Transmit Delay timer. Some work
environments may have an inherent level of motion that would be detected by higher settings of the
accelerometer, so a lower level of sensitivity might be needed. Midian recommends experimenting to determine
the best sensitivity setting for the work environment.
