(The exact model number depends on which and how many RF modules are installed.) 1.2 DESCRIPTION The TDFM-600/6000 series of transceivers are airborne multiband radios capable of conventional FM, P25, SmartNet and SMART ZONE trunking systems. RF modules are available in VHF, UHFLO, UHFHI and 800 MHz bands. The bands are numbered 1,4,5 and 8 respectively. The following are typical model examples: TDFM-655 TDFM-688 TDFM-6148 TDFM-6158 1.3 Two UHF high band modules Two 800 MHz modules One VHF, UHF low and 800 MHz module One VHF, UHF high and 800 MHz module TECHNICAL CHARACTERISTICS Specification Characteristic Model Designation: TDFM-600/6000 Physical Dimensions: Approx. 8" X 3" X 5.75" Weight: 3 Lbs (1.2 kg) -30°C to +60°C Operating Temperature Range: Power Requirement: Voltage: Current: 28.0 Vdc, ± 15% 165mA minimum 5A maximum RF Output Power: 1 or 6 Watts (VHF) 1 or 4 Watts (UHF) 1 or 3 Watts (800) Frequency Range - VHF Module: UHF LO Module: UHF HI Module: 800 Module: 136 to 178 MHz 403 to 470 MHz 450 to 512 MHz 806 to 870 MHz Audio Output Power (including sidetone): 500 mW into 600 ohms Microphone Inputs: Carbon or Equivalent Panel Back Lighting: 28 VDC or 5VAC (specified when ordered) 1-1 SECTION 2 OPERATING INSTRUCTIONS 2.1 GENERAL A 2 line display and a keypad and 2 or 3 rotary knobs provide the operator control of the 2 or 3 RF modules installed in the unit. The display is showing the activity of one RF module at a time, selected by pressing the desired knob. The knobs have multiple functions including volume, channel, display dimmer. The microphone, key line and headphone audio are separate for each of the two or three bands therefore switching from band to band is performed at an audio panel such as the Technisonic A710 series. This allows for separate and simultaneous operation on each of the bands just like having 2 or 3 separate radios. If combined operation is desired, a Technisonic AMS-6000 audio mode selector may be used ahead of the audio controller. 2.2 FRONT PANEL Refer to the diagram below: 2.3 POWER SWITCH To switch the transceiver on, press and hold the left most knob until the radio powers up. The display will show TECHNISONIC and the software version installed followed by the model number as determined by which RF modules are installed. The display will then show the normal display for band 1. To switch off the transceiver at any time, press and hold the left most knob for 2 seconds until the display shows OFF then release. If it is desired that the radio comes on with the radio master in the aircraft, a power jumper may be installed (see installation instructions) such that the radio is always on. 2-1 2.4 KNOBS The transceiver will have two or three knobs depending on how many RF modules are installed. The knobs are rotary encoders which turn endlessly which means their actual position is not important. Each knob also has a push button incorporated in it so you can press the knob as well as turn it. Pressing a different knob will cause the display and keyboard to switch to the band associated with that knob. The knob will start out as a volume control. Pressing the same knob again will change its function to act as the channel/talkgroup selector depending on how that band is programmed. Pressing the same knob again changes the function of the knob to a display dimmer control. Pressing the knob again causes the key pad function to change from function keys to number keys. The knob in this mode acts as a volume control. Another knob press will bring you the recall mode (if this feature is enabled in the configuration menu). Typing in the channel number will bring you quickly to that channel without scrolling through channels in between. Pressing the knob again brings it back to the first mode of volume control. The current function of the knob is shown at the top right of the display. The function of the knobs of the unselected bands are always in volume control mode. The starting mode (when the band is selected) of the knob can be programmed in the configuration menu to be VOLUME or CHAN. 2.5 SOFT KEYS AND HOME The transceiver has three soft keys which assume the function shown above them on the display. The functions displayed depend on how the module was programmed with the radio service software (CPS)™. Functions can be different on a channel by channel basis as well. These may include: ZONE - Pressing this function will prompt you for a new zone number which can be entered directly or scrolled using the UP and DN keys. MUTE - Selecting this function will prompt you for an on or off entry using the soft keys to mute the tones. Tones refer to the beeps heard when pressing buttons. VIEW - The view function is used to view lists. Lists can include phone numbers, call lists and or page. PWR - Selecting PWR will allow the power output of the radio to be set to high or low. PROG - Selecting PROG allows brings you to user programmable features of the radio such as telephone numbers. The ability for the user to program phone numbers, etc can be enabled or disabled by the CPS™. At any time while in one of these functions, you can escape back to the normal mode by pressing the HOME key. When programming the modules with the CPS™, it is suggested not to double up functions. For example, programming a soft key to CHAN would be redundant since there is already a channel function using the knobs. Using the CHAN soft key would also not update the channel number on the display, causing some confusion. 2.6 FUNCTION KEYS Four function keys at the top of the keypad provide the same actions as the three side buttons and the top button found on the XTS-3000 portable. They are as follows: F1 - Top side button (purple button) on the portable. F2 - Center side button (with one dot) on the portable. F3 - Bottom side button (with two dots) on the portable. F4 - Top button (orange button) on the portable. 2-2 TDFM-600/6000 Transceiver Recommended Keypad Menu Defaults: Conventional Operation (H35) SmartNet Operation (H37) SMARTZONE Operation (H38) Top Side Button 1 Monitor Phone Phone F2 Key Center Side Button 2 Scan Scan Scan F3 Key Bottom Side Button 3 Talkaround/ Direct Private Call Site Display/Search F4 Key Orange (Top) Button Emergency Emergency Emergency MUP and MDN keys 16-Position Rotary Knob Channel Select Channel Select Channel Select ESW Key Two-Position Concentric or Ergo Switch Blank (O) Low Power (∅) Blank (O) Low Power (∅) Blank (O) Low Power (∅) Three-Position Toggle Switch Blank (A) Scan (B) Blank (C) Blank (A) Scan (B) Blank (C) Blank (A) Scan (B) Blank (C) TDFM-600/6000 Portable ITEM ITEM F1 Key TSW Key Note: It is possible to use Motorola’s Radio Service Software (RSS™ or CPS™) to alter the default keypad settings of the TDFM-600/6000 series radios. However if custom key settings are chosen it will not be possible for Technisonic to help the Pilot or other Radio User through operational difficulties. These questions will have to be referred to the Radio System Administrator responsible for customising the settings. Technisonic recommends that the default key settings stay in place until all airframe installation and operational issues have been overcome. The TDFM-600/6000 series Transceivers are programmable by Motorola Radio Service Software. The following settings may be programmed for each Channel in a Conventional Radio: Tx Frequency Tx PL/DPL Code Rx Frequency Rx PL/DPL Code Time-Out Timer Scan List Phone Smart PTT Zone Channel Name RX Signal Voice Type TX Signal Voice Type Network Access Code Tx Power 2-3 The following settings must be programmed for each mode in a Trunked (SmartNet or SMARTZONE) Radio: System Type System ID Individual ID Coverage Type Affiliation Type Control Channel 1 Control Channel 2 Talkgroup 1 Talkgroup 2 TG Strapping Zone Scan List Scan Type Interconnect Phone Display Format Private Call Private Call Type Private Call Operation The function keys along with the rest of the key pad, revert to normal number keys during transmit and when NUM LOCK is selected by pressing the rotary knob. 2.7 MUP AND MDN KEYS These keys provide the same function as the rotary knob does when it is set to CHAN. This equates to the 16 position rotary knob on the portable. When one of these keys is pressed, the function of the rotary knob is automatically set to CHAN. 2.8 UP AND DN KEYS The keys provide the same function as the left and right arrow keys on the portable. The UP key equates to the right arrow key. These keys are used for a variety of functions but in the normal mode they are used to scroll through the soft key menus. 2.9 BRT AND DIM KEYS Use these keys to dim or brighten the display. The radio powers up at full brightness for normal use but can be dimmed for night operations. 2.10 ESW KEY The ESW key provides the function of the concentric or ‘ergo’ switch on the portable. The switch has two conditions which are represented by ‘O’ and ‘∅’. Pressing the ESW key toggles the condition back and forth. The condition is displayed at the bottom of the display, second character from the right. The ergo switch condition is saved when the unit is turned off. There are separate conditions for each band installed. The ESW key can be programmed with the CPS™ to a variety of functions such as low power, scan, channel, and secure mode. 2.11 TSW KEY The TSW key provides the function of the toggle switch on the portable. The switch has three conditions which are represented by ‘A’, ‘B’ and ‘C’. Pressing the TSW key toggles the condition A,B,C,A,B, etc. The condition is displayed at the bottom of the display, last character on the right. The toggle switch condition is saved when the unit is turned off. There are separate conditions for each band installed. The TSW key can be programmed with the CPS™ to a variety of functions such as low power, scan, channel, and secure mode. 2-4 2.12 DISPLAY The transceiver has a two line, 48 character LED display which gives information about the selected band. On the top line is shown the zone number, channel name and rotary knob function. The bottom line displays the soft key menu, the band selected, and the ESW/TSW condition. Also displayed are letters and symbols indicating scan, direct/repeater talk around, monitor, secure, priority and call. In addition to the character display, there are two LED indicators on the left. The top LED indicates a signal is being received on the selected band while the bottom LED indicates that any one or more of the installed bands are transmitting. 2.13 GENERAL OPERATION Switch on the transceiver as described in 2.3. Select the desired band by pressing the appropriate knob. Select the same band on the audio panel. Press the knob again so that CHAN shows up on the top right of the display. Rotate the knob until the desired channel or talk group is selected. Press the knob until VOL is again shown on the display. You can adjust the volume by waiting until a signal is received or by pressing F1 (factory programmed for monitor function) and adjusting the rotary knob. The radio is ready to use. Remember that the band selected by pressing the rotary knobs is what is displayed on the screen but the band selected by the audio panel is band that you are actually transmitting and receiving on. If another band is displayed, the rotary knob for the band you are using is still operating the volume level. To use the DTMF key pad while transmitting, the band you are using must be displayed on the screen. 2.14 RADIO SERVICE SOFTWARE (RSS™ for DOS or CPS™ or Windows) To make any changes to the programming in the radio, RSS™ or CPS™ software must be used. There is no provision in the radio to allow the user to change frequencies, zones, talk groups, etc. CPS™ software can be purchased from your local Motorola dealer. A Motorola Radio Interface Box (RIB) is required to connect the computer to the TDFM600/6000. Each band in the TDFM-600/6000 is considered an XTS-3000 (normally) or an XTS-5000 (upgrade) portable by the CPS™ software. To program a band in the transceiver, it must be selected by pressing the appropriate knob before running the CPS™. Follow the instructions supplied with the CPS™ and RIB. The radio cable supplied with the RIB will not connect to the TDFM-600/6000, therefore you will need to fabricate or purchase the XTS-3000 or XTS-5000 type programming cable. FIGURE 2-2 XTS-3000 Programming Cable (Requires RIB) 2-5 2.15 CONFIGURATION MENU Some features of the TDFM-600/6000 transceiver can be configured to the user’s preference. To enter the configuration menu, turn the unit on while simultaneously pressing the F4, ESW and TSW keys. Hold the keys until the display reads ‘Configuration Menu’. The first menu item to show will be ‘Knob Default’. Rotating the left knob will toggle back and forth between ‘volume’ and ‘channel’. This will select which mode the knobs will be in when you select a band or when the radio is first turned on. Press the left knob to accept the desired setting. The next menu item is ‘Recall Mode’. Rotating the left knob will enable and disable this feature. When enabled, a recall mode is added to the available knob functions. Press the left knob to accept the desired setting. The last menu item is the ‘Auto reset’ function. Rotating the left knob will toggle the function ‘enabled’ or ‘disabled’. This function should be left enabled. However, if a module has failed or has been removed from the radio, this feature should be disabled to prevent the radio from continuously trying to establish communication with the missing or failed module. Press the left knob to accept the setting. The radio will then power up normally. The radio will keep these settings until they are changed again by the configuration menu. 2.16 FLASH UPGRADE MODE On occasion it may be required to flash upgrade one or more of the modules in the radio to change or add new features. This can be done using the Motorola RIB box and software supplied in a Motorola flash upgrade kit. The transceiver must be put into flash upgrade mode by turning on the radio while holding the HOME key. Select the band to be upgraded by pressing the desired band knob. Follow the software instructions. During the flash procedure, the software will ask you to turn off and on the radio, use the RESET soft key, do not turn off the transceiver. 2-6 SECTION 3 INSTALLATION INSTRUCTIONS 3.1 GENERAL This section contains information and instructions for the correct installation of the TDFM-600/6000 Transceiver. 3.2 EQUIPMENT PACKING LOG Unpack the equipment and check for any damage that may have occurred during transit. Save the original shipping container for returns due to damage or warranty claims. Check that each item on the packing slip has been shipped in the container. 3.3 INSTALLATION The TDFM-600/6000 Transceiver is designed to be dzus mounted and should be installed in conjunction with an IN600 installation kit. See figure 3-1 for an outline drawing of the unit with dimensions to facilitate the installation. 3.4 INSTALLATION KIT - CONTENTS The IN-600 installation kit (P/N 019301-1) consists of: 1. 2. 3.5 One 25 pin Cannon D mating connector (female) complete with crimp pins and hood. 3 BNC connectors. ANTENNA INSTALLATION The type and number of antennas depends on the model of transceiver being installed. The following is a list of recommended antennas for the various RF modules: VHF UHFLO UHFHI 800 136 to 176 MHz Comant part # CI-292 403 to 470 MHz Comant part # CI-275 450 to 512 MHz Comant part # CI-275 806 to 870 MHz Comant part # CI-306 The antenna should be mounted on the bottom of the aircraft whenever possible. Consult with instructions provided with the antenna. Connect the RF cables to the back of the transceiver using the BNC connectors provided in the installation kit. 3-1 FIGURE 3-1 Outline Drawing for Model TDFM-600/6000 3-2 3.6 INSTALLATION - PIN LOCATIONS AND CONNECTIONS J1 - 25 Pin D Connections - Use FEMALE Connector Pin # 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Description Ground Main Power +28 VDC Mic 1 Audio 1 PTT 1 Mic 2 Audio 2 PTT 2 Mic 3 Audio 3 PTT 3 TX Data RX Data Ground Main Power +28 VDC Channel Up Channel Down LH Data SB9600 Busy OPTB+ CTS Out Boot DIN RTSBIN RS232DIN Panel Backlighting TABLE 3-1 3.7 INSTALLATION - WIRING INSTRUCTIONS Figure 3-2 shows all required connections and recommended wire sizes for the TDFM-600/6000 transceiver. 3.8 MAIN GROUND - PINS 1 AND 14 Both pins should be connected to ground. The main ground is internally connected to the chassis. 3.9 MAIN POWER +28 VDC - PINS 2 AND 15 Both pins should be connected to +28 volts DC +/- 15%. 3-3 3.10 MIC 1, 2 AND 3 - PINS 3, 6 AND 9 The microphone input signals shall be connected using shielded wire with the shield connected to ground (pin 1 or 14). It is recommended for best results to leave the other end of the shield floating to prevent ground currents unless you are connecting to an audio panel with floating hi and lo inputs (like the Technisonic A710 or A711 series) in which case the shield must be connected to the lo input. 3.11 AUDIO 1, 2 AND 3 - PINS 4, 7 AND 10 Audio outputs 1, 2 and 3 are 600 ohms impedance against ground. The output power is 500 mW maximum. 3.12 PTT 1, 2 AND 3 - PINS 5, 8 AND 11 The PTT lines should be floating when in receive and grounded for transmit. The input has a pull up resistor to 5 volts. Connecting an audio panel which wishes to see more, may result in no receive audio. Connect a 1N4006 diode in series with the cathode towards the audio panel in this case. 3.13 TX DATA AND RX DATA - PINS 12 AND 13 These are an RS-232 serial port for the RC-6000 remote control head if installed. Consult the RC-6000 installation manual for details. 3.14 CHANNEL UP AND CHANNEL DOWN - PINS 16 AND 17 These pins can be used to scroll up and down through the zone/channel/mode/talk group selections for the band currently displayed on the screen. The inputs normally floating are grounded to activate. Two push buttons or a center off, SPDT, spring loaded toggle switch are typically used on these inputs. 3.15 LH DATA, SB9600 BUSY, OPTB+, CTS OUT, BOOT DIN, RTSBIN AND RS232DIN - PINS 18 THROUGH 24 These pins are used for programming or updating the transceiver using Motorola Radio Service Software (RSS™) or encryption key loading and are generally left unconnected. However, if it is desirable to update the radio without removing it from the aircraft, these lines can be run to a 25 pin D male connector located on the panel where a laptop computer can plug in. Use the same pin numbers so the programming cable described in section 2 can be used (minus the power pins). 3.16 PANEL BACKLIGHTING - PINS 25 Connect to aircraft panel dimming bus. The transceiver comes with either 28 VDC or 5 VAC backlighting circuits. Check the label on the side of the transceiver before applying power. 3.17 POWER JUMPER The radio must be turned on manually each time the avionics bus is switched on. If it is desired that the radio comes on with the radio master in the aircraft, remove the right side panel from the radio and install a 0.1” jumper across JP1 (two pins) near the rear of the radio on the right side of the MCU board. If you attempt to turn off the radio with the jumper installed, it will just come back on again in 5 seconds. 3-4 FIGURE 3-2 Wiring connections and notes for the TDFM-600/6000 Transceiver 3-5 3.18 POST INSTALLATION EMI TEST PURPOSE The purpose of this test is to identify any interference that the TDFM-600/6000 transceiver may cause with existing aircraft systems. TEST CONDITIONS The TDFM-600/6000 transceiver should be installed and function tested. The antenna VSWR should be checked. A forward/reverse power check with a in-line wattmeter should show no more than 10% reflected power. For the following tests, insure that the output power is set to high. METHODOLOGY Most of the EMI tests can be accomplished on the ground. In some cases flight testing is required or is easier. If the aircraft is approved for IFR operations, then it is mandatory that interference between the TDFM-600/6000 transceiver and the approach aids be checked in flight. The GPS should be operational and navigating with at least the minimum compliment of satellites. The VHF comm should be set to the frequencies indicated with the squelch open. VOR/DME receivers should be set to the frequencies indicated and selected for display. If possible, set up a DME ramp test set on the frequencies indicated and adjust the output until the flags are out of view. The transponder and encoder should be monitored with ramp test equipment. Set the output of the transponder test set to 3db above the output necessary to achieve 90% reply. If possible set the ADF to a nearby navigation station. Modulate the TDFM-600/6000 transmitter on the indicated frequencies for at least 20 seconds. Observe the GPS for any degradation in satellite status or availability or flags. Listen for any noise or detected audio signals on the VHF comm(s). Listen for any noise or detected audio signals on the VOR/LOC receiver audio; look for any moment of flags or needles on the VOR/LOC/GS navigation display(s). Observe the transponder for any loss of reply or spurious reply. List the power plant, fuel and other electric instruments in the chart provided and note any anomalies that occur while transmitting. Assess the results. If the aircraft is equipped with an autopilot or a stability augmentation system, then test fly the aircraft and verify that operation of the TDFM-600/6000 transceiver does not have adverse effects on these systems. After checking for gross effects at a safe altitude, fly an approach with each of the different navigation systems coupled to the autopilot (ILS, GPS ETC.) and look for any anomalies. 3-6 RESULTS If the installed system passes all of the applicable EMI tests, then no further action is required. If interference is observed then the interference must be assessed against the appropriate standards of airworthiness for the system in question. For example it is permissible for a VFR certified GPS to lose navigation capability while the TDFM-600/6000 unit is transmitting, providing that it recovers properly and promptly, but it is not permissible for an IFR Approach certified GPS to be affected in the same way. A complete discussion of all the standards of airworthiness to be applied in assessing EMI effects is beyond the scope of this document. PROCEDURE A. Operate the TDFM-600/6000 transmitter on the following frequency for at least 20 seconds. Observe the GPS for any degradation in satellite status or availability or flags.
