Overview Introduction Overview The Model 360 Radio Remote system allows a user to operate a remote Kenwood TK-780, TK-880, TK-980, TK-981, TK-7180, TK-8180, NX-700, or NX-800 mobile radio. The system passes transmit and receive audio and provides access to radio functions. The Zetron system includes one or more Model 360 Radio Remotes and a Model 360 Radio Interface. Figure 1.
Introduction System Features • Extended local remote control of Kenwood TK-780, TK-880, TK-980, TK-981, TK-7180, TK-8180, NX-700, and NX-800 radios • Radio controls and indicators represented on the Model 360 Remotes with a comfortable, easy-to-use keypad layout • 12 programmable function keys plus a DTMF keypad for access to more radio features • Instant Calls allow the radio to be sent to a pre-set system and group with a single keystroke • Alpha-numeric text aliases for each group, up to 16 cha
Typical Configuration Typical Configuration A system consists of a radio, a radio interface, and one or more remotes. Up to twentyfive remotes can be connected in parallel to control a single radio via a radio interface. Each remote can be located up to 2000 feet from the radio. Remotes connect to the radio interface with three pairs of in-building twisted wire. The radio interface is co-located with the radio and connects to the radio’s KCT-19 cable. Figure 2.
Introduction Installation is simple because the audio levels come pre-set from the factory. Furthermore, maintenance and repair are minimized because of the advanced microprocessor circuitry used in the design of these products.
Introduction Installation Caution! This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instruction manual and commonly used radio practices, it may cause interference to radio communications. The Model 360 Radio Remote system should be installed by personnel experienced with remotes and radio systems. Introduction Figure 3 shows a typical system installation. A modular cable connects the radio interface to a telephone wall jack.
Installation Figure 3. Typical System Installation Installation Steps Installation of the Model 360 Radio Remote system is done in three phases: • Program the radios • Configure system components • Install and connect system components • Initialize the system Before beginning installation, read all of this section and the Operations section to become familiar with the components, the system functions, and how different settings interact.
Radio Programming TK-x80 Series Radio Programming Note When configuring a radio, the technician should start by setting the radio to its default values and then change/verify the parameters specifically mentioned in this manual. The settings called out in the manual are required. Those settings not mentioned should be left at their default values. This will give you a basic configuration that is known to work.
Installation 5. In the Fleetsync Menu: Note A Fleetsync ID must be programmed into the radio to make it respond correctly to commands. • Emergency Status Response = None • Status Message Stack = No • Caller ID Stack = No • Status Message Serial Output = Yes • Unit ID Serial Output = Yes • Caller ID Display = No TK-x180 Series Radio Programming These instructions provide the installer and user with a straightforward guide to getting the radio and the Model 360 functional with basic settings.
Radio Programming The following list identifies the major differences between a TK-x80 and TK-x180 installation. If you are already familiar with TK-x80 installation, this list can help you prepare for TK-x180 installation. • TK-x180 radios do not have a dedicated external PTT line. This function must be defined and assigned to one of several possible programmable AUX I/O pins on the DB-25 connector. This function and pin assignment must be made to pin #13.
Installation 3. Since there is a likelihood that a microphone may not be attached to the transceiver when installed with an Model 360, you must ensure that no radio functions affecting Model 360 or FleetSync operation would be inadvertently disabled: a. Click Edit, Optional Features, Common-Page 1. b. Enable Off-hook Decode. By enabling this, the transceiver opens the squelch by matching the QT/DQT signaling depending on the Audio Control settings and regardless of the Mic Hook On/Off status.
Radio Programming Note Although scanning can be remotely started and stopped using the Model 360, please be aware that the console user will not know the identity of the channel that scanning stops at, as this is not reported back via the Model 360. Should you wish to use scanning, remember the Off Hook Setting also applies to this function and its proper operation. In the Scan Information Menu, ensure that “Off-hook Scan” is selected. 4. In the Common-Page 3 menu: a. Set PTT ID Type to FleetSync. b.
Installation Tip Details regarding the use and interaction of the port settings for COM 0, 1, and 2 are discussed in the radio’s programming manual and can be accessed by clicking Help. 5. In the FleetSync Menu, under the General 1 Submenu: a. Define the radio’s own Fleet ID. b. Define the radio’s own Individual ID. c. Set Emergency Status Response to None. d. Set PC Interface Protocol to Ver.1.
Radio Programming 6. In the FleetSync menu, General 2 menu: a. Clear the Status Message Stack checkbox. b. Clear the Caller ID Stack checkbox. c. Mark the Status Message Serial Output check box. d. Mark the Unit ID Serial Output checkbox. e. Mark the J Command Serial Output check box. 7. The TK-x180 series has several programmable AUX I/O pins that can be assigned input or output functions as desired.
Installation 8. The external TX audio input utilized by the Zetron Model 360 is the DC-Coupled low level “MI2” line permanently assigned to pin 6. To configure transmit audio input: a. Navigate to the Extended Function Menu, Modulation Line tab. b. Set the MI2 Line/External PTT (Voice) field to Connect. c. Set the Mic Line/MIC PTT field to Disconnect. d. Set all others to Disconnect. Note The Mic Line/Mic PTT field should typically be set to Disconnect.
Radio Programming Note Due to differences in various versions of the radio programming software, some settings may have slightly different names and may be located in different windows or tabs than those shown here. The specific software shown here is “KPG111D” v2.10. To configure a NX-800 radio for basic settings: 1. From the Edit menu, select Optional Features and Optional Features 1.

Installation System Initialization The last installation step is initializing the system. This includes powering up and checking the transmit level. Power-Up To power up the remotes: 1. Plug the wall transformer into a power outlet or connect the 12 Vdc supply. 2. To turn the radio interface on, turn the radio on. Note When the radio or radio interface are programmed (read from or written to), power must be cycled on both or the system will not function properly.
Introduction Programming Introduction The Model 360 Radio Remote system comes from the factory pre-configured with usable default settings. However, most users will benefit from tailoring the system configuration to their application. System configuration includes system parameters governing overall system operation, function key and keypad key assignments, text aliases, and instant calls.
Programming The original specifications for the computer necessary to run the program are: • DOS version 3.0 or later • 250KB of free memory • a 3½-inch disk drive • a hard drive with 100KB of free space • a 25-pin RS-232 serial port (or a 9-pin RS-232 serial port with a 25-pin adapter). If you can still find a machine that meets these original specifications, then you can simply proceed to follow the original instructions and program your radio interface unit.
Setup Windows XP To install the software on a Windows XP machine: 1. From the distribution CD, double-click on the Install M360KA.bat file. 2. The batch file will execute the following actions: a. Creates the C:\Dosbox folder and copies the Dosbox program into it b. Creates the folder C:\Zetron\M360KA c. Creates a link on the desktop called M360KA, using the following icon 3. Double-click on the desktop link for the M360KA. This will cause the following to happen: a.
Programming USB-to-Serial port setup for Windows XP: 1. Install your USB-to-Serial convertor in the USB port in which you intend to use it. 2. Open the Start menu and right-click on the My Computer link. Select the Properties option from the pop-up menu that opens. 3. In the System Properties dialog that opens, click on the Hardware tab, and then click on the Device Manager button that appears at the top of the Hardware tab. 4.
Setup Windows 7 Note Installing the Dosbox application on a Windows 7 machine will most likely require that you temporarily turn off the UAC function on that computer. Turning off the UAC on a Windows 7 machine: 1. Click the Start button, followed by Control Panel link. 2. In the Control Panel Window, click on User Accounts. 3. In the User Accounts window, click on the Change User Account Settings link. 4.
Programming In addition to the issue of not being able to find a computer still running the DOS operating system, many newer computers do not have serial ports available. It that case you will need to use a third-party USB-to-Serial port convertor and configure the USB port to answer up as COM1 or COM2.
Setup Editing the M360KA.conf File This section provides tips for editing the M360KA.comfig file in order to support placing the Model 360 programming software in an alternate location or to allow the serial port used to be assigned to some other port than COM1 or COM2. To alter the M360KA file location: 1. Start the Notepad program, or any similar text editor utility suitable for editing a configuration text file. 2. Browse to the folder that contains the M360KA.conf file.
Programming Configuring the Programming Software To configure the programming software: 1. Run M360KA.EXE. 2. Select Setup and choose COM port to select which serial port the computer will use to program the radio interface (COM1 or COM2). 3. Select Setup and choose Printer to select which parallel port the computer will use to print the configuration file (LPT1, LPT2, or a file on disk). Connecting the Programming Adapter To connect the programming adapter: 1.
Programming Programming The steps in programming a radio interface are: • Create a new configuration file with default settings, open a saved configuration file from disk, or read the configuration settings from a radio interface. • Edit the settings as desired. • Write the configuration settings to the radio interface. You may save a configuration file to disk for later use and/or print it out for reference. Old configuration files may also be deleted using the programming software.
Programming Menus This section describes the commands available on the menus. File Menu New This command creates a new configuration with default settings. Open Use Open to open an existing configuration file. Save Choosing Save will save the current configuration file under its current name. Save as This command saves the current configuration file under a different name. This is useful when you want to base a new configuration on an old one, but still keep the old configuration file.
Menus Edit Menu System parameters The following list describes the programmable system parameters. Default settings are in italics. Handset Hookswitch This command Enables or Disables the handset hookswitch’s control of the radio hookswitch. If enabled, removing the handset from the cradle will take the radio offhook, and replacing it in the cradle will put the radio back on-hook.
Programming On Hook Exits Privacy This command Enables or Disables any remote from exiting privacy mode whenever its handset is returned to the cradle. Line Check The Line Check command Enables or Disables the remotes from detecting a problem with their data links to the radio interface. If this feature is enabled, and a remote is unable to contact the radio interface for three minutes, it will display “No Radio Found” in the bottom line of its LCD until the data link is restored.

Introduction Operation Introduction This section describes the operation of the Model 360 Radio Remote. The controls and indicators are described, followed by a description of remote features. The section ends with a description of the audio options available. This section does not explain how to operate the radio. For a full description of the radio, its features, and operation, refer to the radio user guide.
Operation Figure 8. Model 360 Radio Remote ZETRON Model 360 Radio Remote TX OPT BUSY MON HOME D/A SCAN A B C D 1 2 ABC 3 DEF 4 GHI 5 JKL 7 PRS 8 TUV 6 MNO 6 MNO 9 WXY * 0 # I′CM MUTE PVCY TX Remote Controls Programmable Function Keys The Model 360 Remote has 12 programmable function keys (two sets of up/down arrows, MON, HOME, D/A, SCAN, A, B, C, and D). Any of several radio or remote features can be assigned to each key.
Remote Controls 12-Key Keypad The 12-key keypad mimics the keypad on the radio microphone. It is used primarily to send DTMF over the air. In addition, each key can be assigned a secondary function similar to the other programmable keys. In order to use these secondary functions, one of the normal programmable keys must be set to Function. To activate the secondary function of a keypad key, press the Function key.
Operation Handset Hookswitch The handset hookswitch switches audio between the front panel mic/speaker and the handset mic/earpiece. It can also be configured (in system programming) to control the radio hookswitch. Volume Knob The Volume knob adjusts the volume level of the audio from both the front panel speaker and the handset earpiece at the same time. Remote Indicators System & Group The current system and group (or group and channel) numbers are displayed in the top line of the LCD.
Remote Features The In Use icon turns on while a user at another remote is controlling the radio and stays on for about one second after they stop pressing keys. While this icon is on, no one else can control the radio. This prevents users from interrupting one another. TX, OPT and Busy LEDS These LEDs reflect the LED on the radio. If the LED on the radio is red, the TX LED turns on. If the LED on the radio is yellow, the OPT LED turns on. If the LED on the radio is green, the BUSY LED turns on.
Operation Mute To mute the receive audio of a Model 360 Remote, press the Mute key. The Mute LED will illuminate. The mute function does not time out and does not affect other remotes. To unmute the receive audio, press the Mute key again. The Mute LED will turn off. Mute will also cancel if the Transmit key is pressed. For information on disabling mute for a single remote, see Table 3 on page 32.
Remote Features Supervisor Any number of remotes in a system can be configured as Supervisors. These remotes are immune to the effects of privacy mode. In other words, when another remote initiates privacy, all Supervisor remotes will still be able to hear both sides of the conversation and to control the radio. When a Supervisor remote initiates privacy, the mode will not time out.
Operation If controlled by the handset, when the handset is removed from its cradle, the radio is taken off-hook, and when the handset is replaced, the radio is placed back on-hook. Pressing a function key programmed for radio hookswitch will toggle the radio between on-hook and off-hook. The LED next to the key will turn on while the radio is off-hook and turn off while the radio is on-hook. Either method can be used by itself, or both methods can be used together.
Audio Accessories Line Check If the Line Check feature is enabled in system programming, the remotes will detect when their connection to the radio interface is lost. This is a troubleshooting feature used to indicate wiring faults and power failures. It allows the remote user to differentiate between a properly working system with no radio traffic, and a system that has stopped functioning. Failures are detected within three minutes.
Operation • Use the jack sense signal on the optional headset interface box to activate and deactivate the headset. Plug the headset into the box to use it, and unplug the headset to use the front panel microphone and speaker. Depending on system programming, the radio can automatically be taken off-hook when the headset is activated. In that case, the off-hook state will time-out after four minutes and the radio will be placed on-hook.
Introduction Troubleshooting and Repair Introduction The Model 360 Radio Remote system uses the latest hardware and software techniques to minimize complexity and number of parts. This improves reliability so that the units should not require service. If a problem should arise, however, this section will help identify the problem and a solution. Before using the service hints in the following table, go through the installation procedure again to make sure all the steps were completed.
Troubleshooting and Repair Service Hints Problem Possible Solution Audio can be heard from the remote, but the display is blank and the remote LED on the radio interface keeps blinking. The polarity of the data lines is probably backward. Change the position of JP7 in the radio interface. Audio can be heard on the remotes, but a Supervisor remote is muted when another remote enters privacy mode. Check jumper JP3 on the Supervisor remote main PCB. It should be in position B.
Software Upgrades Software Upgrades From time to time, Zetron may release new versions of the Model 360 operating software. The changes may add new features, enhanced existing ones, or reflect changes in radio firmware. This section explains how to install a new version of software. System Programming If the radio interface software needs to be upgraded, protect system programming by: 1. Save a back-up copy of the radio interface system programming to disk using the Model 360 Programming Software. 2.
Troubleshooting and Repair To install the EPROM: 1. Turn off the power. For the remote, unplug the wall transformer. For the radio interface, unplug the cable to the radio. 2. Remove the cover of the unit. 3. Locate and remove the old EPROMs from the board. 4. Install the new EPROMs in the designated sockets with the orientation notches aligned with the notches in the sockets. Make sure that the EPROMs are fully seated, and that no pins are bent. 5. Replace the cover of the unit. 6.
