Pins not listed within this table are all defined as no connects. when the “Power On/Off Control" signal is momentarily connected to “Radio Ground" and then released, it causes the power on/off state of the radio to toggle. This can be utilized in conjunction with the “Radio +5 vac" signal to insure the radio is powered on for operation. Note that radio units will maintain the power on/off state across removal of the primary power to the radio. As such, users need not utilize this control signal but may simply always leave the radio in a powered on state. when delivered from the factory, radio units are left in a power on state. 7D-STR1600>000 STE—1600 0&M Manual For the channel select lines described above, the following table defines the control functions of these yinputs‘ TABLE 2—5 CHANNEL SELECTION CONTROL SETTINGS FRONT PANEL 25 PIN D SIGNAL STATES DEFINITION ‘ Channel Select 2 Channel Select 1 Channel Select 0 t ' ‘ ‘ Select Chan 1 Select Chan 2 Select Chan 5 ‘ Select Chan 7 Select Chan 8 SECTION 3 OPERATION Operation of the radio is accomplished by utilizing a special software program to configure has radio for the proper configuration and than connecting the system into the target platform for audio data transmission and reception. The following sections describe the radio operations from the perspective of configuring the unit for the proper radio channel characteristics prior to final system installation. 3.1 Minimum System Requirements This package requires a PC executing under the windows operating system. The version of Windows may be Windows 95, windows 98, or Windows 2000. At a minimum, the system should include: o 16 Mb RAM (32 Mb recommended) 0 Color monitor (minimum of 600x800 pixel resolution) 0 2 Mb available hard—drive disk space 0 Serial port (COMl: through COM4:) 0 . 3 1/2 “ floppy disk drive 3.2 Software Installation The control software for the radio is provided on a set of 3 1/2” floppy disks. The first disk of the set will contain the program “setup.exe". Executing this program activates a standard windows software installation process with full instructions as to required user actions. The installation will create the program “str1600.exe" in the specified install directory. 3.3 Conventions and File Structures The radio control software supports standard Windows type operation, including menu based selection processes. Throughout the remaining portions of this document, a reference such as “select aaaa : bbbb” indicates a Windows type menu selection process where aaaa is the text name which appears at the top of the active program screen and bbbb is the submenu item displayed once the ease menu is selected. Further submenu items are preceded by the same .- and then the text name of the lower submenu item. In addition to the STR1600.exe program, the install directory will also contain the file “prefs.cfg” after the first execution of the program. This file is utilized to record user settings (e.g., communications port selection) such that these configurable items can be carried forward across executions of the program. The radio control program utilizes Labview, a; software package from National Instruments. The install directory also contains other support files associated with the run—time version capability required of Labview for the control program. 10 3 . 4 Getting started 3 . 4 . 1 Radio Int-rconnect Before taking any actions from the control program with TACTICAL radio, the radio must be connected to a primary power source and to the PC via a special programing interface cable and adapter. The following figure depicts the required interconnects. Programmlng DBQ Interface Comm Pan Adaptor Conniaor 13.6 VDC Power STR-1600 Supply Radlo Prlmary 0925 power AudlolConlro! Programming Connector Connecmr Interface Cable FIGURE 3-1 RADIO To PC INTERCONNECT CONFIGURATION The 13.6 VDC power supply need only support the radio operation in a quiescent mode (i.e., < 0.7 A). The power up sequence of the radio versus the PC is not critical. The interconnect from the radio to the PC is via an interface cable and adapter provided with the software (SRI P/N 50—STR1600—200). The cable consists of a DB9 female connection on one end and an RG45 male connector on the other end. The D59 end should be plugged into any standard serial communications port on the PC. DB9 to D525 adapters may be utilized as required. The interface adapter accepts the RG45 connection on one side and interfaces with the STR-1600 female DB-25 front panel connector on the other. The adapter also includes an LED and a momentary push button switch on the sides of the plastic housing. 3.4.2 Power-on Sequence Once the above configuration has been established, the primary power supply and PC should be powered on and initialized. when the primary power is activated to the radio . the LED on the side of the programming interface adapter should illuminate. This indicates that the radio has successfully powered up in an “ON” condition. 11 If the LED fails to illuminate within two (2) seconds, the user should attempt to establish an “ON” condition by momentarily activating the push button on the side of the programing interface adapter and then releasing it. If a radio has been inadvertently left in an “OFF” condition, this will toggle the state, which should then illuminate the LED‘ If this action fails to correct the problem, the user should validate the primary power connection to the radio and then attempt the “0N”/”0FF” toggle switch again. 3 .4 t 3 Reading the Radio Configuration Assuming the above process is successful, the user can proceed to activate the STRlGOO.exe program. This will result in the following sample screen on the PC's monitor. r/quR FIGURE 3—2 CONTROL SOFTWARE INITIAL SCREEN If this is the first time the program is being utilized or if the operator has changed the PC’s serial communications port being utilized, the first action taken by the user should be to establish the correct port selection. This can be accomplished by selecting Com Port : OOM1:, Com Port : COMZ:, Comm Port : comm, or Port : COM4:. The port selection will immediately be changed and the new configuration will be recorded to disk for future executions of the program After this action, the user may select Radio : Read Radio. This will cause the software to interrogate the interconnected radio and then update the displayed fields. The Serial Number field should reflect the five (5) digit serial number from the product label on the radio r. gThe model number will indicate the specific model of the radio and the low and high frequency values will indicate the valid operational frequency range of this particular model. The right hand side of the screen indicates the current settings for the eight (8) preset channel selections of the radio. This includes the channel 12 frequency, bandwidth (i,e., wideband at 25 KHz or narrowband at 12.5 KHz) and output power level (i.e., 5 Watts or 30 Watts). 3.5 Altering the Radio Configuration 3.5.1 Changing Individual Channel fittings Once a radio has been read as described above, the channel configuration fields on the right hand side of the screen may be edited. The frequency field may be changed via standard text edit methods, or it may be incremented or decremented via the arrows located at the side of each setting. The bandwidth and power selections are toggle controls which flip states each time the user selects the button. After establishing the changes to all channel settings, the user should select Radio : Write Radio. The system will again interrogate the radio as to it’s current settings, modify the channel configurations according to the edited fields, and then write the new configuration back to the radio. By interrogating the radio again prior to modifying it’s settings, the software insures the correct configuration update even if a new radio has been connected to the PC since the last read radio action. As such, a user may establish a channel configuration and then write the data to multiple radios simply by connecting a new radio to the PC and invoking Radio : Write Radio, The fields on the left hand side of the screen will be updated each time this action is taken‘ The software does not preclude the operator from establishing invalid configuration settings, but it does prevent these settings from being written to the radio. As such, an operator may edit a channel frequency field to values outside of the indicated range for the current model, but it will notify the user of the error and abort writing the configuration after the Radio : Write Radio action is taken. Similarly, channel frequencies not centered on 25 KHz steps for wideband or 12.5 KHz steps for narrowband will be cause an abort of the configuration update. 3. 5.2 Setting/ Changing Modal Defaults The radio control software supports user default settings for each of the six(6) model types. An operator may establish settings for the eight (8) channels pertaining to frequency, bandwidth, and output power levels and then store these as the default settings for that model type. This information is stored on disk and, as such, the settings will carry across executions of the control program, To establish a particular model default, the user must connect a radio of that model type to the PC. Selecting Radio : Read Radio will update the display to the information appropriate for that model of radio. The user then may change the frequency, bandwidth, and power level settings that should be utilized for the defaults. After carefully checking the configuration, the operator should select File : Save Current Settings as Default for this Model. After interrogating the user as to the validity of this action, the system will replace the previous default settings with the new configuration Each model type only supports a single default configuration. 13 After having established the desired defaults, any radio can be updated to the defaults simply by connecting it to the PO and then taking the single action of selecting Radio : Writ. from Default Settings for this Model. This action will cause the software to interrogate the radio, determine the model type, and then write the sppropriat‘éy default settings: for the channel configurations. At the same time, the display will be updated to reflect the new information for the radio‘ 3 . 6 Radio Ops-ration Having established the proper channel configuration for the radio, the radio is now ready for target platform installation. The following operational considerations should be noted: 1) Radios which are powered up with an active push- to-talk condition will not operate until the push— —to-talk is removed and stay’ 5 in a non—active condition for a period of 2 seconds. 2) On initial power up or on any change of the frequency select lines into the radio, the target frequency setting may take up to 1 second to obtain. 3) If push—to~talk is active at any time during the 1 second tuning period outlined in note 2 above, the tuning action will not complete until push-to—talk is removed and stay’s in a non-active condition for a period of 2 seconds. 14 SECTION 4 MAINTENANCE In order to ensure that the radio system is always ready for operation, it should be checked periodically so that potential defects my be discovered and corrected before they develop into any serious damage or system failure. A minimal preventive maintenance program will significantly increase the systems life span‘ This section describes the necessary preventive maintenance checks and tests the user can perform to easily identify most defects and problems. Any other defects or problems discovered during the normal operation of the system should be noted for future corrective measures. CAUTION Stop the operation of the system immediately if a problem is noted during normal operation, that can otherwise damage the system. This section also describes the corrective maintenance checks that can be performed on the radio system. 4 . 1 Maintenance Concept The maintenance concept for the radio system is limited to the removal and replacement of the entire unit. 4.2 Preventive Maintenance Requirements The following is a recommended timetable for performing preventive maintenance checks on the radio. CAUTION Primary power to the radio must be turned OFF when performing preventive maintenance on the equipment. 4 . 2 . 1 Inspection The radio system should be inspected periodically for defects or physical damage developed during operation. Inspect all the interface cables to and from the system for cracks, breaks and proper seating with their mating connectors on the card. Inspect all cables for frayed, broken or damaged wires. In addition, inspect all-radio connections for accumulation of dirt, grease, or any foreign material that can cause a non—connection. If a cable is found damaged or non-repairable, it should be replaced before operating the system again. 15 70—STR1600—000 5111—1600 cm Manual Inspection should benperformednat least once'every month. The frequency of inspection should be increased for units exposed to dusty or heavy particulate environments. ' 4 . 2 . 2 cleaning Clean the outside surfaces and areas around the ‘connectors‘vpe dibally. Clean the surfaces with a clean, soft, lint-free cloth. Clean 'he areas around the connectors with a soft bristle brush. To remove grease, fungus, or corrosion, use a cloth dampened with an appropriate electronics cleaning fluid. Cleaning should be done at least once every ‘month. The frequency of cleaning should be increased for units exposed to dusty or heavyrparticulate environments .
