TRANSCEIVER OPERATION
HOW TO SET UP EACH TRANSCEIVER
1. LOCATION
Each Transceiver is designed to be placed on a flat surface for stability. The
transceivers are not weatherproof and should be placed indoors or in an
environmental enclosure if used outdoors or in a harsh environment. Included in
each of MicroTek’s environmental enclosure is a piece of double-sided tape that
can be used to mount the transceiver inside the housing.
2. POWER
The MiniLink Data unit is powered by a 6-20 VDC power supply connected
through the power jack at the side of the transceiver. Each transceiver
incorporates reverse voltage protection and will draw 200 mA of power.
3. SOFTWARE CONFIGURATION
MiniLink Data 900 or 2400 MHz Transceivers are preprogrammed at the factory
with the following settings:
Baud 4800
Flow Control None
Data Bits 8
Parity None
Stop Bits 1
If your system is using the above listed protocol, there is no need to install the
supplied MiniLink CTU Software. Identify the type of data configuration your
system will be using and make the data connection using the RS-232 DB9
connector or RS-485/422 4-position screw terminal. See section C “DATA
CONNECTIONS” above for the different connection types.
4. MINILINK CTU SOFTWARE
The MiniLink-CTU Software included with the MiniLink Data 900 or 2400 MHz
Transceiver is provided in case it is necessary to change the parameters of the
transceiver for a particular application.
• To install the MiniLink-CTU Software double-click on the
“minilinkctu.exe” located on the media included with your transceiver.
Follow the prompts of the installation screens.
• To use the MiniLink-CTU Software, connect the MiniLink Data
transceiver from the DB9 connector on the unit to the COM1 serial port of
a PC using the supplied straight through DB9 Serial Cable. Remember that
the Baud Rates of the COM1 serial port and the transceiver must match,
and 4800 is the factory setting. Also make sure that the mode select switch
is in the RS-232 position.
• The MiniLink-CTU Software is organized into 3 tabs:
i. Set-up
ii. Com Test
iii. Configuration
- 5 -
TRANSCEIVER OPERATION (Continued)
1. Set-up Tab
This screen is used to set the PC Serial Port to interface with the MiniLink Data 900
or 2400 MHz Transceiver. The parameters in this tab must match the PC Serial Port
Parameters for communication to be established.
2. Com Test Tab
This screen is used to test the MiniLink Data transceiver and monitor
communications once the two transceivers are both set to match the parameters of
your system.
Running a Com Test: (See Notes and instructions on the CTU Software below before testing)
1. Two Data transceivers must be in RS-232 mode, powered up, and antennas attached in
order to communicate with one another.
2. One transceiver must be connected to a PC or laptop using the 9-pin DBP Serial Cable
to the PC’s Com Port A, with the CTU Software loaded and running. The other unit must
have pins 2 and 3 grounded with a paper clip.
3. Click on the “Com Test” tab & click “Start”. Test results should appear on the screen
(Either “Good” or “bad”). You can click “Stop” when you like. Click “Clear Results”
and switch the units to make sure they pass the test as a transmitter and as a receiver.
3. Configuration Tab
This screen is used to configure the MiniLink Data 900 or 2400 MHz Transceiver parameters.
• To establish communication between the MiniLink Data Transceiver and the
MiniLink-CTU Software, click on the configuration tab, and select “Show Advanced
Set-up” then click on the “Get Parameters Using Com Port A” tab. The AT
command mode, Sleep, Radio Set-up and Network field will populate if the Baud
Rate on the “Set-up” tab and the Baud Rate of the radio match. (Factory set to 4800).
If the fields do not populate, check the Com Port A setup parameters and retry.
• To change parameters, click on the field or drop down arrow you wish to change and
enter the desired value. Click “Program Module” to send the new parameters to the
MiniLink Data Transceiver. In most cases, only the Baud Rate will need to be
changed.
• To verify that the radio is now configured to the desired parameters, click on the
“Set-up” tab and set all applicable fields to the new setting and click on the
“Configuration” tab. Then click on “Get Parameters Using Com Port A” and all
fields should populate and represent your desired settings.
- 6 -
TRANSCEIVER OPERATION (Continued)
• Avoid clicking on “Restore Module Defaults” as Multiple Default-Resets could
result in a software lockout, requiring a factory reset of the Transceiver unit(s). If
you are experiencing software difficulty, try refreshing by clicking on a separate file
tab such as “Set-up” and re-click “Configuration” then try the command again.
NOTE: All transceivers communicating with one another in a system must be configured identically.
If the parameters are changed and the MiniLink transceiver is disconnected from the PC, the com port
parameters of the PC will need to be changed to match the transceiver to re-establish communication.
5. ORDER OF SETUP AND OPERATION
1. Connect Power. A red light, or an LED, will be viewable near the RS-485 Connector
inside of the case once power is applied.
2. Connect Data input. (See page 4)
3. Set the Mode Select switch to the data protocol used by the device being controlled.
4. Make sure the antenna is attached to the SMA connector.
a. Data 900 Transceivers use a 7” omni-directional dipole antenna that flexes at
its base.
b. A Data 900 20-Mile System will use one 7” omni-directional dipole antenna
on one transceiver and the other transceiver will use a 30” Yagi directional
antenna with a 10’ cable that connects to the SMA connector.
c. Data 2400 Transceivers use a 4” omni-directional dipole antenna that does
not flex at the base.
d. A Data 2400 10-Mile System will use one 3” omni-directional dipole antenna
on one transceiver and the other transceiver will use a 12” x 12” Patch
directional antenna with a 10’ cable that connects to the SMA connector.
6. MAINTENANCE
Your MicroTek Electronics MiniLink Data Transceiver is an example of superior design
and craftsmanship. The following suggestions will help to ensure maximum operational
life.
• Keep the product dry. If it does get wet, wipe it dry immediately. Liquids may
contain minerals that corrode electronic circuits.
• Use the system only within the environmental specifications indicated. High
temperatures can shorten the life of electronic devices and melt plastic parts.
• Excessive mechanical shock can damage the case, connectors, cable or internal
circuit board.
Moving or tampering with the system’s internal components can cause a malfunction and
will void the systems warranty as well as the FCC authorization to operate it. If you
cannot control your system wirelessly or if you are having any other problem, contact
your dealer and/or MicroTek for service.

TROUBLESHOOTING
PROBLEM SUGGESTION
Camera does not respond
when PTZ control
functions are moved
Unit fails when Com Test
is run
There is a slight “blip” or
other type of interference
on the screen only when
the PTZ control functions
are accessed.
No wireless control should be the only problem that would be related
to the MiniLink Data transceivers. For all other problems, refer to
the operations manual for other equipment that is being used. Try the
following suggestions to obtain wireless control:
1. Verify mode selection switches are in the UP position for
RS-422/485 or in the DOWN position for RS-232.
2. Both transceivers must match parameters.
3. Transceivers’ parameters must match the system they are
communicating with.
4. If using RS-422/485 protocol, make sure it is wired into TX
+/- at the control panel and RX +/- at the camera.
5. Run a Com Test in RS-232 (in the CTU Software) to verify
that each radio is transmitting and receiving data.
6. One or both radios may need to be returned for testing and
repair under its 2-year limited warranty. Call MicroTek for
return for repair information.
1. Make sure that pins 2 and 3 of the DB9 connector (on the
unit not plugged into the PC) are grounded using a paper
clip.
2. Verify that both transceivers match all parameters.
3. Verify both units’ mode selection switch is in the RS-232
position.
4. Both transceivers should have their antenna connected to
work properly.
5. Make sure both units are powered up and their LED is on.
6. Switch radios so that the one previously connected to the PC
is now the transmitting unit with the grounded pins.
7. One or both radios may need to be returned for testing and
repair under its 2-year limited warranty. Call MicroTek for
return for repair information.
The MiniLink Data Transceivers should not interfere with any of the
MiniLink Video Transmit/Receive systems since the frequencies are
too far apart. The exception to that general rule is if you are using
the MiniLink Data 2400 Series alongside the MiniLink 2.4 GHz
Series for video. Otherwise, the problem may be a power issue.
Make sure that each data transceiver and each video transmitter (or
receiver) is powered by its own 12 VDC power supply.
