GENERAL INFORMATION
Midian’s VAE-1-SM1G is a GPS speaker microphone voice alarm encoder that can have a voice message stored
in it and when the emergency switch is activated the VAE-1 will transmit an emergency ANI and/or the
prerecorded voice message. The voice alert is ideal for providing location information when GPS location is not
available (i.e. in buildings, tunnels, etc.) The following is a common application:
Emergency Location and Lone Worker: The VAE-1 is ideal for providing voice location messages for Public
Safety (firefighters and police) or for lone workers in areas where GPS location is not available. For example,
firefighters can store a custom voice message into the VAE-1 as their location changes while fighting a fire in a
building. If there is a fire in a ten story apartment building and the firefighter is working on the second floor in
apartment 215, the firefighter can record “Second floor apartment 215”. If the firefighter moves to the third floor in
apartment 306 the firefighter can rerecord the message to say “Third floor apartment 306”. If the emergency input
is activated (by a button press or the lone-worker feature) then the VAE-1 will send an emergency ANI to identify
to the dispatcher who is in trouble and then the voice message will follow to inform the dispatcher the distressed
firefighter last recorded location. This enables the rescuers to concentrate their search efforts in one area of the
apartment building rather than splitting their search efforts between ten stories. Locator tones can also be
generated to provide an audible alert to the searchers.
The VAE-1-SM1G 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 VAE-1-SM1G also offers Man-Down and Lone Worker features. If the unit does not detect movement (Man-
Down) 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, the VAE-1-SM1G 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.

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 external 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 VAE-1-SM1G 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.

6
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 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 based on the sensitivity
setting.
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 power-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 immediately 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.
Voice Compression: If left unchecked the VAE-1 can store up to a 3-minute voice message. If checked the VAE-
1 can store up to a 2.25 minute voice message, but with a higher level of audio quality.

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 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: Currently not used.
Locator Tone Enable: If selected the unit will emit tones out the radio’s 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.

12
Mute GPS or MDC-1200 ANI Packet: If checked, the unit will detect incoming GPS or MDC-1200 ANI packets
and will mute the speaker for the Mute Duration time. A small chirp will still be heard out the speaker.
Mute Duration: This sets the amount of time after the unit detects the incoming packet that it will keep the
speaker muted. Midian’s GPS data packet without location is 200 msec and with location is 410 msec. Motorola’s
MDC-1200 data packets are approximately 180 msec in length.
Packet Detector Sensitivity: This controls the sensitivity of the preamble tone detector which triggers the muting
of the data packets. If it is too sensitive (higher number), voice may cause the detector to trigger resulting in voice
being muted when it should not. If it is not sensitive enough (lower number), the detector may not trigger when it
is supposed to. Adjust the sensitivity as needed to achieve the desired results. For the GPS speaker microphones
with scrambling, there is a separate sensitivity adjustment for when the unit is in scramble mode.

13
Transmit Frequency: When the emergency input is grounded the unit sends an Emergency ANI either once or
multiple times. This field tells the unit to send the voice alarm with the emergency ANI only on the first Emergency
ANI or on all Emergency ANI’s.
Require PTT to Record: Most radios will only pass audio to the option board when PTT is pressed. If this is the
case this box must be checked. In this mode a button is used to put the unit in record mode and then the PTT is
pressed to pass audio to the unit. The unit keeps the audio from being transmitted in record mode, but only if the
PTT path is broken.
Auto Review: After message recording is completed the unit will replay the message over the speaker to confirm
the message.
Save Message When Powered Off: This will keep the last recorded message in memory when power is cycled.
Auto Record: If checked the unit will start to record immediately upon power up. If the Require PTT to Record
box is checked it will wait for the PTT.

14
These fields set how the switch is used (short press, long press or double press) and for which function (Lone
Worker enable, Lone Worker Reset, Emergency On/Cancel, etc.).
Note: Most portable two-way radios do not give a COR indication to the speaker microphone connector, so VOX
detection should be used.
COR > Active Polarity: This sets whether the unit looks for an active low or active high to come out of power
save.
COR > Debounce: If checked the unit will require a continuous active state for 30 msec before accepting the
COR.

15
PTT > Active Polarity: This sets the polarity necessary for the unit’s PTT output to key the radio.

16
These fields set how the switch is used (short press, long press or double press) and for which function (Lone
Worker enable, Lone Worker Reset, Emergency On/Off, etc.).
Trunking Delay Input > Active Polarity: This sets whether the unit needs an active low or active high indication
from the radio to indicate a trunked channel has been established. Typically not available in this product.
Trunking Delay Input > Debounce: If checked the unit will require a continuous active state for 30 msec before
accepting the Trunking Delay Input. Typically not available in this product.

17
Tones > Beep Volume: Adjust the slider for the desired beep volume. This level is expressed as a percentage of
max voice audio level.
Tones > Over-The-Air-Signal Modulation: Adjust the slider for the desired signaling modulation level. This level
is expressed as a percentage of max voice audio level.
Playback > Playback Level: This controls the audio level when a stored voice message is played back on the
radio speaker. If voice playback is too low or too loud, adjust this level accordingly.
Playback > Transmit Level: This controls the audio level when a stored voice message is retransmitted over the
air. If the transmit level is too low or too loud, adjust this level accordingly.

18
AUDIO ALIGNMENT
This section describes how to determine and set the audio levels.
The procedures below can be used to approximate the response of the internal microphone or another speaker
mic accessory. These measurements must be taken within 15 seconds of powering the scrambler on. This is
because the scrambler may enter power saving mode after that time. Measurements made while the scrambler is
in power saving mode will not be valid.
1. A method for controlling transmitter modulation is required for accurate measurements in the TX mode. A
small speaker held in place near the microphone by a rubber band can serve this purpose in most cases. Use
a sine-wave generator to inject a 1000 Hz tone into the speaker. Adjust the output of the sine wave generator
so that the transmitter produces 60% of rated modulation while PTT is pressed.
2. Leaving the generator output set to the same level, install the SM-1 microphone with the same set up as
above. Press PTT and using a communications monitor, observe the modulation level.
3. In the programming software, adjust MIC Out to obtain 60% modulation.
4. Spkr In should be set to 1980 mvpp using 60% modulation.
5. MIC In and Spk Out should be set to 1920 mvpp using 60% modulation.

19
OPERATION
The SM1 has three buttons; PTT, Button 1 and Button 2. The PTT button is the larger oblong button, Button 1 is
the top round button with one nub and Button 2 is the bottom round button with two nubs.
PTT Button:
The PTT button is used to send a PTT command to the radio to cause the radio to transmit and send the ANI.
Button 1 and Button 2:
Button 1 and Button 2 are momentary buttons that can be programmed for Lone Worker On/Off, Lone Worker
Reset and Emergency ANI. The functions can be selected by a short press, long press (press and hold for 1.5
seconds) or double press.
Record Start:
Message Recording on Power Up: If the Auto Record feature is enabled the unit will record a voice
message immediately upon power up. Press the PTT button to record the voice message. The unit will not
give a PTT to the radio during record mode.
Message Recording with Mode Button: Pressing the assigned button in the programmed manner (i.e. short
press, long press) will cause the unit to start recording. Press the PTT button to record the voice message.
The unit will not give a PTT to the radio during record mode.
Record Stop/Play: Pressing the assigned button in the programmed manner (i.e. short press, long press) will
cause the voice message recording to stop and the unit will play back the message over the speaker for
confirmation if the Auto Review box is checked.
Lone Worker On/Off: Pressing the assigned button in the programmed manner (i.e. short press, long press) will
turn the Lone Worker feature on and off. When enabled the unit must have user interaction (i.e. PTT press,
movement or Lone Worker Reset button press) within the programmed amount of time otherwise the unit will
send the Emergency ANI.
Lone Worker Reset: Pressing the assigned button in the programmed manner (i.e. short press, long press) will
reset the Lone Worker feature. The Lone Worker feature can also be reset by pressing the PTT or the
accelerometer detecting motion (if programmed).
Emergency ANI: Pressing the assigned button in the programmed manner (i.e. short press, long press) will
cause the unit to send the programmed Emergency ANI.
Man-Down (Accelerometer):
If programmed for Emergency ANI, Lone Worker or both and the unit does not detect motion for a programmed
amount of time, the unit will key and generate the Emergency ANI. The movement detection threshold is
programmable.
ANI Encode: When the PTT button is pressed and/or released, the unit will assert the PTT Output and send the
programmed ANI tones to the radio.
ENI Encode: When button programmed for Emergency ANI is pressed, or the Lone Worker or Man-Down
features are activated, the unit will assert the PTT Output and send the programmed Emergency ANI tones and
the voice message to the radio.

20
Decode Functions:
Query: When the speaker mic receives a Query command from the CAD-800 it will transpond back indicating if it
is currently enabled or disabled.
Polling: When the speaker mic receives a Polling command from the CAD-800 it will transpond back to the CAD
with the unit’s last location fix.
Selective Call: The unit is capable of receiving three types of selective calls; individual, group and all. The
individual call is based on the group ID and unit ID. The group call is based on only the group ID. The all call is for
all units within the system. The unit will transpond back to the CAD-800 only on the individual call. The ring tones
consist of 50 msec of 627 Hz & 1320 Hz dual tone alternating with 50 msec of 627 Hz 1670 Hz dual tone. The
individual call ring consists of one long warble tone that lasts 1.6 seconds with a 4 second gap between rings. The
group call ring consists of a double warble tone (600 msec on, 400 msec off, 600 msec on) with a 4 second gap
between rings. The all call ring consists of a triple warble tone (400 msec on, 200 msec off, 400 msec on, 200
msec off, 400 msec on) with a 4 second gap between rings.
Radio Disable & Radio Enable: If a radio becomes lost or stolen or the user does not pay for access, the
speaker microphone can be “disabled”, so it will no longer key the radio or pass receive audio from the radio.
When disabled it will still respect Query, Polling and Spy commands. If the radio is found it can then be
Spy (Remote Monitoring): When the Spy command is received by the unit it will PTT the radio and pass audio
from the microphone to the radio for transmission. The length of time of this transmission is programmable for 15
seconds, 30 seconds, 45 seconds or 60 seconds.
Emergency Acknowledge: If the unit is programmed to send the Emergency ANI continuously or for multiple
times, the receipt of the Emergency Acknowledge command from the CAD-800 will cause the unit to stop the
emergency sequence and no longer send Emergency ANIs.
