2.0 T2000UAV-L DESCRIPTION

The UAV-L version of the T2000SFL has no display. The chassis has been truncated by having the display housing milled off. The front face is plated off and sealed.

A command set allows the UAV's flight management system to have full functional control over the transponder. The RS-232 interface is accessed from the DB-25 connector on the rear face of the chassis.

The T2000UAV-L requires a standard Gillham code altitude encoder, to supply altitude data over a 10 line parallel interface.

3.0 SOFTWARE CONTROL

The T2000UAV-L can be controlled by issuing of commands in the form of ASCII characters, sent and received over an RS232 interface.

The command set can be used to either poll the transponder of the status of a parameter, or to command a function to a particular setting.

3.1 MICROAIR UAV TERMINAL SOFTWARE

The T2000UAV-L is supplied with UAV Control software to which it is capable of issuing all commands, and polling for all parameters. The terminal software is a simple EXE file, and is compatible with windows 98 through to windows XP operating systems.

T2000UAV Terminal Software.exe

The terminal software is capable of issuing all of the commands, to either poll for any of the parameters, or to set any of the parameters to discrete values.

3.2 THE UAV COMMAND STRUCTURE

The T2000UAV-L is controlled by a series of simple commands. The T2000UAV-L can be commanded to set a code, and to operate in a particular mode. Once the code is set, and the operating mode decided, the T2000UAV-L will operate until another command is received.

The status the T2000UAV-L's various operating parameters can be queried. A query command returns a value for that particular parameter.

The operator can address the T2000UAV with a command from the command set, via an RS232 interface. The command requires the correct syntax, to be valid.

The command string will consist of STXx=ETX

Where STX is the non-printable ASCII character (02)

ETX is the non-printable ASCII character (03)

x is a valid command

maybe either ? or a string of ASCII characters, if the is a ?, this will evoke a response for that command

3.3 DATA SPEED

The RS232 interface for the T2000UAV-L has a data rate of:

9600,N,8,1,P

where 9600 = baud rate of 9600

8 = 8 data bits

1 = 1 stop bit

P = with XON / XOFF

Refer to section 10.0 for wiring details and pin assignments.

3.4 SERIAL DATA COMMAND SET

3.4.1 STANDBY (S=T)

To bring the T2000UAV-L to the standby condition, the "s" parameter is set to value "t". Then the transponder can then be powered down. When the T2000UAV-L is restarted, it will return in standby

The transponder should be commanded to the standby condition, when the vehicle is on the ground. The transponder is typically set to mode 3A or mode 3A/C operation once airborne.

3.4.2 MODE 3A (S=A)

The T2000UAV-L transponder will respond to all mode A interrogations with the identity code set by the "c" parameter. The transponder will also reply to all mode C interrogations with just the framing pulse (no altitude data). This ensures visibility to TCAS operators, while the transponder is operating in mode A.

3.4.3 MODE C (S=C)

The T2000UAV-L will respond to all mode A interrogations with the identity code set by the “c” parameter, and all mode C interrogations with the encoder’s altitude data, as defined by the “a” parameter. The transponder will reply to both SSR and TCAS interrogations.

3.4.4 IDENT (I=S)

The ident function is performed at the request of ATC to “squawk ident”. To initiate the ident function the “i” parameter is set to s. The T2000UAV-L will switch to ident mode, which will add an additional data bit to the outgoing replies. The additional data bit makes the transponder return on the ATC display flash to assist the controller with identification. The transponder will remain in ident mode for 18 seconds, and then return to the previous mode of operation.

3.4.5 ALTITUDE (A=?)

The T2000UAV-L will reply with the current mode C value.

If the T2000UAV-L is configured to operate with an altitude encoder the T2000UAV-L will reply with the current barometric altitude from the encoder.

If the T2000UAV-L is configured to operate with a serial altitude data source, the T2000UAV-L will reply with the last received altitude data value.

3.4.6 ALTITUDE SOURCE (D=?)

The T2000UAV-L can accept altitude data for the mode C response either from a Gillham (d=g for 10 line parallel) source or from a serial (d=s for RS232) source.

When d=g is selected the T2000UAV-L will look to the 10 line Gillham input for data from an altitude encoder.

When d=s is selected the T2000UAV-L will look for altitude data to be passed via the “a” command on the RS232 serial data link. The altitude data source shall send the a= where the altitude value is between -1000 and 62000 feet, in increments of 100 feet. The altitude data source should issue this data report to the T2000UAV-L no slower than 1Hz.

Where the altitude data cannot be detected from the assigned source or the data cannot be encoded, no altitude data will be outputted. The mode C response will be framing pulses only. The T2000UAV-L will question the altitude data with a=?, via the RS232 serial interface.

3.4.7 ENCODER POWER (E=?)

When using an altitude encoder, it may be desirable to only have it powered up when the transponder is operating in mode C. This may save power, as most encoders will typically draw 125 to 150mA when operating.

The operator should allow up to 7 minutes for the encoder to “warm up” before valid altitude data is outputted from the encoder.

3.4.8 VOLTAGE (V=?)

The T2000UAV-L will report the current vehicle bus voltage by polling the “v” parameter. To use this function operator must first set the reference bus voltage by setting v=1 for 14V operation, or v=2 for 28V operation.

3.4.9 REPLY ANNUNCIATOR (R=Y)

A conventional transponder normally has an annunciator of some type (typically a flashing LED) to indicate the rate of reply to SSR interrogations. This indication represents whether the transponder has made a reply to a “sweep”. The rotational speed of the radar is 100 deg/sec, hence the Annunciator should flash every 3.6 seconds.

The equivalent function for the T2000UAV-L is the "r" command which activates the reply annunciator. When activated (r = y) , the T2000UAV-L will send a single * character, if there was a reply made in the preceding 3.6 seconds. When not activated (r = n) , no character is sent.

The operator can query the status of the reply annunciator function (r=?), and the T2000UAV-L will reply with the current function state.

3.4.10 PING FUNCTION (P=?)

The ping function is a self test of the RF sections of the transponder, without the need for a transponder test set. The T2000UAV-L will respond to the “ping” command (p=?) by emitting a narrow (invalid) pulse from the transmitter, and detecting the same pulse back through the receiver.

If the T2000UAV-L is able to complete the transmission cycle, p=y is returned to the operator.

If the T2000UAV-L is not able to complete the transmission cycle, p=n is returned to the operator.

The ping function will only operate if the transponder is in mode a or c. The ping function will not operate while the transponder is in standby mode.

4.0 T2000UAV-L TIE DOWN STRAP

Microair recommends a simple tie down strap, to hold the transponder in place. Drawing MA1156 shows the layout and use of a simple example.

Never use the case screws as part of the mounting system for the transponder. Always locate the strap over the chassis at a point which remains clear of the filter lock nuts.

5.0 MODE C ENCODER

Mount the mode C blind encoder as per the manufacturer's installation instructions. All wiring can be run back to the T2000UAV-L for connection (refer wiring diagram). The power for the encoder is supplied from the T2000UAV-L. This power is switched when the T2000UAV-L is turned on.

IMPORTANT NOTE

Most encoder manufacturers advise of a warm up period for their product before altitude data is supplied. The period can typically be up to 10 minutes.

Where the OEM intends to use their own barometric altitude data source, it should comply to TSO C88a standard, to be sure of compatibility with the T2000UAV-L.

Although it is unlikely that the encoder source in a UAV installation will require switched power from the T2000UAV-L, it is recommended that the ground be wired with the data lines in all cases. This will ensure correct signal operation of the Gillham code.

6.0 ANTENNA

Mount the transponder antenna as per the manufacturer's installation instructions. Try and keep the cable runs as short as possible. In a composite airframe a suitable ground plane will be required. Avoid mounting the antenna inside a fuselage that is all metal or carbon fibre.

For fiberglass fuselages the antenna may be mounted internally, but must still point downwards and have an adequate ground plane. Alternatively an approved dipole strip antenna may be used. The dipole strip must be installed in accordance with the manufacturer's instructions.

To avoid possible interference the antenna must be mounted a minimum of 200mm (8 inches) from the T2000UAV-L main unit. The transponder antenna should be mounted 2metres (78 inches) from the DME antenna, 1.5 metres (58 inches) from the ADF sense antenna, and 1metre (39 inches) from TCAS antennas.

7.0 COAXIAL CABLE

The T2000UAV-L allows for 1.5dB cable loss from the unit to the antenna. The installer should consider carefully what type of coaxial cable is to be used, so that this loss limit is not exceeded. The cable should be terminated with silver plated BNC connectors where possible.

Microair recommends the following:

Cable Bending Radius		Loss @ 1Ghz dB/m	Max Length TX	Power RX Sensitivity
RG58/C/U(Mil Spec)	50mm(2")	0.76dB/m0.21dB/ft	2.0m7ft	142W	-70dBm

RG223/U(Mil Spec)	100mm(4")	0.47dB/m0.14dB/ft	3.2m10ft	142W	-70dBm
RG400(Mil Spec)	50mm(2")	0.60dB/m0.18dB/ft	2.5m8ft	142W	-70dBm
Belden 8262 50mm(2")		0.68dB/m0.21dB/ft	2.2m7ft	142W	-70dBm
URM-43	50mm(2")	0.47dB/m0.14dB/ft	3.2m10ft	142W	-70dBm

The loss figures in this table are a guideline only. When installed the power output at the antenna shall be greater than 125W and receiver sensitivity shall be better than -68dBm, to be compliant with RTCA/DO-144A.

IMPORTANT NOTE

Do not exceed the minimum bending radius. Tight bends will introduce losses in the cable, which may affect the performance of the transponder. When fixing the coax cable in the airframe, do not “strangle” the cable with tight cable ties. This can distort or damage the coax screen.

8.0 WIRING

The T2000UAV-L Transponder receives primary power (14V or 28V dc) from the aircraft's power source. Power connections, voltage, and circuit breaker requirements are shown on the wiring diagram. The length of the power supply wires to parallel pins should be approximately the same length, so that the best distribution of current can be effected.

Microair recommends that the encoder be installed and wired in accordance with the manufacturer's installation instructions.

It is very important to secure all D series plugs via their security screws before operation. Aircraft vibration may disconnect a D series plug if it not secured.

Where possible, the antenna coaxial cable should be run separately to all other wiring on the aircraft from the transponder.

8.1 CABLING

Microair recommends that wiring for all of the T2000UAV-L's functions and connections be run at the time of installation, even though they may not be required at this stage. Adding additional wiring to the loom at a later stage may be very difficult.

All wiring should be installed in accordance with FAA AC43.13-1A Chapter 11 or equivalent.

Microair recommends the following cable types for connection of the T2000UAV-L:

Power Input 18 AWG TEFZEL 22759/16-16 Red and Black Wire

External Connections 22 AWG TEFZEL 22759/16-22 22 AWG

Wire or TEFZEL 27500-22TG1T14

Single core shield

Encoder Power 22 AWG TEFZEL 22759/16-22

Red and Black Wire

Encoder Data 22 AWG TEFZEL 22759/16-22

White Wire

When terminating the DB plugs for connection to the T2000UAV-L, ensure that the wires are securely soldered to the pins, and that each wire is separately insulated with heatshrink tubing.

Close-up of a hand using a tool to connect a cable or wire component (no visible text or symbols)

Locking bolts tightened

The DB-25 plug is secured to the T2000UAV-L with machine screws or thumb screws. The DB-15 should also be secured to the encoder, either with screws, or mechanical sliding lock (if fitted to some types of encoder).

If your encoder is fitted with a slide locking mechanism, the encoder manufacturer's plug should be used, to ensure correct locking action.

8.2 POWER ON/OFF

The T2000UAV-L has no ON/OFF control function. The unit is on from the moment power is applied to the unit. There is no software OFF command. When power is removed from the T2000UAV-L, it will not respond to any software command.

When the T2000UAV-L is turned on, it is always in standby mode. The mode A code will default to the last mode A code used.

IMPORTANT NOTE

Always bring the T2000UAV-L to standby before turning off the power. If the transponder is powered off while it is in the process of transmitting, damage may occur to the internal power supply and/or the transmitter. Damage of this type is not covered by the warranty.

No mode C code will be outputted until the T2000UAV-L is supplied with altitude data (either serial or Gillham) which can be encoded by the transponder.

8.3 SUPPRESSION IN / OUT

The suppression IN line is wired to other avionics such as DME, to “suppress” the transponder’s transmissions, at times critical to the other equipment’s operation.

The suppression OUT line does the reverse of the IN line. It is wired to other avionic equipment to allow the T2000UAV-L to “suppress” their transmissions at times critical to the T2000UAV-L’s operation.

Seek the advice of a qualified Avionics Technician before attempting to wire out these functions. If certified equipment is modified to operate in conjunction with the T2000UAV-L installation, then the installation of that equipment must be re-inspected and re-approved before operation.

8.4 EXTERNAL STANDBY

The external standby can be wired to a remote switch. When the line is taken to ground the T2000UAV-L will return to standby mode, and stay there regardless of the value for “s” parameter. The “s” parameter cannot be queried while the external standby line is grounded.

Once the external standby line has been “released” from ground, the T2000UAV-L will revert to the last “s” parameter setting.

8.5 EXTERNAL IDENT
