Overview

Overview Hardware / Software Requirements The MPT1327 GOB enables the MOTOTRBO radio to support the MPT1327 trunking feature set. MOTOTRBO radio models supported by the GOB: VHF / 350MHz / UHF Portable / Mobile Display / Non-Display / Limited Display GPS / Non-GPS Software requirements: To work with the MPT1327 GOB, MOTOTRBO radio must contain firmware version R01.08.20 or later.

Overview Feature Set The MPT1327 GOB supports most legacy MPT1327 Professional Series radio trunking features. However, due to hardware limitations there are a few legacy features not supported by the MPT1327 GOB. The MPT1327 GOB also supports some additional features not supported by the MPT1327 Professional Series radios.

Configuration

Configuration Getting Started For the MPT1327 GOB to operate correctly, the MOTOTRBO radio needs to be configured in accordance with the “Radio Setup” section of this training material using the standard MOTOTRBO CPS. The MPT1327 GOB itself must also be configured using a separate GOB CPS in accordance with the “GOB Setup” section of this training material. Both CPS programs need to be installed on the programming PC and the MOTOTRBO radio containing the installed MPT1327 GOB connected to the PC using a standard USB programming cable.

Configuration Radio Setup – Option Board Enabled Channels Whenever the radio switches to an “Option Board” enabled channel, the MPT1327 GOB is automatically activated. For the MPT1327 GOB to operate correctly, configure all “Option Board” enabled channels as follows: Ensure the channel is an analogue channel. Ensure the channel is not placed in any scan list, Auto Scan is disabled and Option Board is enabled. MPT Zone Analog Channels Normal Zone

Configuration Radio Setup – Option Board Enabled Channels Ensure VOX is disabled. Ensure RX/TX Squelch Type is set to “CSQ” and RX/TX Signaling System is set to “None”.

Configuration Radio Setup – General Settings Ensure the radio wide Battery Saver Preamble is disabled.

Configuration Radio Setup – Channel Zones To enable the MPT1327 GOB Personality selection feature, the radio needs to be configured with at least two zones as follows: One zone for the MPT1327 GOB operation, containing 16 “Option Board” enabled channels – these channels are configured in accordance with the previous pages. The other zones for the MOTOTRBO radio (non-MPT1327) operation, containing “Option Board” disabled channels – these channels are configured freely. Notes: Radio users can enter MPT1327 trunking mode by switching from a non-MPT1327 zone to the MPT1327 zone. Radio users can quit MPT1327 trunking mode by switching from the MPT1327 zone to a non-MPT1327 zone. The standard MOTOTRBO CPS may define different zone alias for these zones, however the MPT1327 GOB is unable to display the zone aliases in the personality menu and so it displays a zone index instead. MPT Zone Normal Zone

Configuration GOB Setup The MPT1227 GOB is pre-loaded in the factory with an ‘out of box’ default configuration. If the MOTOTRBO radio enters into MPT1327 trunking mode and the MPT1327 GOB contains its ‘out of the box’ default configuration, then the radio will display “No Personality”. To define the MPT1327 Personalities, the MPT1327 GOB CPS must be used to configure the MPT1327 GOB parameters. Since the MPT1327 GOB CPS reuses much of the legacy Professional Series MPT1327 CPS (with added support for USB), then the MPT1327 GOB CPS should be relatively intuitive to dealers who are already familiar with the Professional Series MPT1327 CPS.

Configuration GOB Setup - Menu Buttons Open a CPS archive file Read codeplug settings from GOB Print current CPS settings You can always click this button to get the related help description for the chosen field. Save current CPS settings as a CPS archive file Write CPS settings into GOB Switch current personality for configuration

Configuration COB Setup – Add / Delete MPT Personality Add/delete MPT personality as below. Note: Display models can have up to 4 MPT personalities, while non-display / limited display models can have only 1 MPT personality.

Configuration GOB Setup - Network Parameters (MPT Network Specific) Set the channel range for Comprehensive Hunt process. Set the dialing plan used by radio Click menu “Network-> MPT Network Specific” to open the configuration window. Set the range for control/traffic channels. Set the system base frequency. It should match system setting.

Configuration GOB Setup - Network Parameters (Hunt Options) These fields define signal levels used during background hunt. Usually no need to change them. Set the background hunt mode Click menu “Network-> Hunt Options” to open the configuration window.

Configuration GOB Setup - Network Parameters (Radio Flags) Some systems require radios to transmit registration info during power up. Check this if needed. Set the required operating bandwidth for the radio Click menu “Network-> Radio Flags” to open the configuration window.

Configuration GOB Setup - Network Parameters (Control Channel Group Definition) When scan for new control channel, the radio will scan all the control channels defined by CPS. If there are many control channels defined,  long time will be needed to scan for a workable channel. The control Channel Group feature is to have a way to organize the control channels in different groups and radio can only scan within specified group. By doing this, the time for scanning can be reduced a lot. Step 1:  Define the control channel groups per users needs: “ALL” is the default group which can not be deleted. Also, only one group can be set as Current. User can via Menu to change the current group: Menu->Settings->Scan Group. Click menu “Network-> Control Channel Group Definition” to open the configuration window. Control Channel Group can be added or deleted.

Configuration GOB Setup - Network Parameters (Control Channel List) Step 2: Assign the control channels used in the trunking system to different Control Channel Groups Add or delete control channels. The channel numbers should be provided by system operator. Click “Edit Group” button to set the control channel for different groups. One control channel can belong to three different groups. In this example, “ALL” group has 440/460; “Group1” has 420/440; etc. Click menu “Network-> Control Channel List” to open the configuration window.

Configuration GOB Setup - Network Parameters (Traffic Channel TPL Code) Traffic channel table. The traffic channel numbers and associated TPL codes should be provided by the system operator. Note: Traffic channels for which TPL is disabled should not be added to this list. MPT FFSK Pre-Time is the delay between the start of the TPL and the FFSK data. This value depends on the TPL detect time of the base station receiver and allows the base station receiver sufficient time to detect the TPL and establish an audio path to the TSC before the radio commences transmitting FFSK data. Click menu “Network-> Traffic Channel TPL Code” to open the configuration window.

Configuration GOB Setup - Network Parameters (Network List Data) Click menu “Network-> Network List Data” to open the configuration window. This windows defines the MPT/MPS system network info. If the radio needs to operate on multiple system networks, then the networks should be added here. The network parameters should be provided by the system operator.

Configuration GOB Setup - MPT Personality Parameters (Call Timers) This windows defines call durations. Note: The MPT/MPS system can also define call durations. The ongoing call will be stopped when the shorter duration is reached. Click menu “MPT Personality->Call Timers” to open the configuration window.

Configuration GOB Setup - MPT Personality Parameters (Personality Data) Set the individual call address range which the radio can call Set the group call address range which the radio can call Set Unit No length, 2 or 3 digits. MPT1343 dialing plan only Set the radio address number Click menu “MPT Personality->Personality Data” to open the configuration window. Set display content when radio power up. This is also used as alias of the current MPT personality Set display content when radio in idle state

Configuration GOB Setup - MPT Personality parameters (Personality Parameters) Check to lock the radio's keypad and disallow keypad operation by the user Click menu “MPT Personality->Personality Parameters” to open the configuration window. Check to enable radio to display group call initiator ID on traffic channel rather than group ID. External alarm is a mobile radio only feature.

Configuration GOB Setup - MPT Personality Parameters (Options) These two features are not supported by MPT1327 GOB Click menu “MPT Personality->Options” to open the configuration window. Check to enable radio to operate in talk group mode. Rotary now is used to choose talk group. Radio only can receive the chosen talk group call in this mode. Check to enable Console to control automatic transmit timer for emergency call. Help Call must be enabled to make this option available.

Configuration GOB Setup - MPT Personality Parameters (Dedicated Call Key) This window is used to configure the Dedicated call and Emergency help call. Programmable buttons can be assigned to the defined dedicated/emergency calls here. Click menu “MPT Personality->Dedicated Call Key” to open the configuration window. The emergency dial string, that is to be used, by the radio, for the emergency call set up. The string must include the call modifier sequence *9* followed by the number string.

Configuration GOB Setup - MPT Personality parameters (Five Digital Lookup Table) The Five Digital Lookup Table enables the keypad string to be shortened when an inter-prefix or inter-fleet call is dialed. A shorter string can be defined here to replace the full Prefix + Fleet number string. In the example below, dialing “20201” results in a call to “2002001201”. Click menu “MPT Personality->Five Digital Lookup Table” to open the configuration window. Routing Address identifies whether an individual ident (for calls to an individual address) or a group ident (for calls to group address).

Configuration GOB Setup - Common (Per Radio Parameters) The item settings in this window affect all the MPT personalities. Click menu “Edit->Common->Per Radio Parameters” configuration window. Check to enable the remote kill feature (needs system support). Once enabled, system operator can send kill/unkill command to specified radio from system side. MOTOTRBO radio provides this feature (configure using standard MOTOTRBO CPS). Not supported. If enabled, password needs to be entered before configuration data can be read from GOB.

Configuration GOB Setup - Programmable Button The item settings in this window affect all the MPT personalities. MotoTRBO radios support 4 programmable buttons. The button functions can be set in this window. Click menu “Edit->Common->Programmable Button” configuration window.

Configuration GOB Setup - Common (Selectable Menus) The item settings in this window affect all the MPT personalities. The menus displayed by the radio can be configured in this window. Click menu “Edit->Common->Selectable Menus” configuration window.

Configuration GOB Setup - Common (GPS Setting) GPS Query defines whether the GPS query function is enabled or not. Short Data Message Type defines what SDM type will be used for the reply. Console Radio ID defines the radio ID ranges. Only SDMs from radios with IDs in the specified ranges will be treated as GPS Query SDMs. SDMs from radios with IDs outside these ranges will be treated as normal messages and displayed on the screen. Note: These IDs must be specified in MPT1327 format. Click menu “Edit->Common->GPS Setting” configuration window.

Operation

Operation Personality Selection To switch between MPT1327 personalities: While radio in idle state, press “Menu” button to enter menu mode. Press ”Left” or “Right” button until “Personality” displayed. Press “OK” to enter Personality menu, whereupon radio displays current personality (e.g. MPT14). Press ”Left” or “Right” button until desired personality displayed (e.g. MPT25). Press “OK” to choose. To switch from MPT1327 trunking mode to non-MPT1327 mode: Press ”Left” or “Right” button until desired non-MPT1327 zone displayed (e.g. Zone 2). Note: It is recommended that zone 1 be configured as an Option Board enabled MPT1327 zone and that all other zones be configured as Option Board disabled zones. It is further recommended that zone 1 contain 16 duplicate Option Board enabled channels. Following these recommendations will ensure that if zone 1 is selected, the MPT1327 GOB is automatically activated and that if any other zone is selected (in the MPT personality menu), the radio automatically exits MPT1327 trunking mode.

Operation Voice Calls To make a voice call from the menu The MPT1327 GOB supports individual and group calls. To make a voice call from the menu To make a voice call directly from the keypad While radio in idle state, use keypad to dial radio address (e.g. 200200120). Press PTT, “OK” or “#” to make call, whereupon radio displays “Calling”. Note: If radio operating in talk group mode, rotary knob can be used to select desired talk group, followed by PTT press to initiate the call directly.

Operation Status Calls The MPT1327 GOB supports status calls (the status message can be predefined by the GOB CPS). To make a status call from the menu To make a status call directly from the keypad While radio in idle state, use keypad to input “*0” (Part of modifier). Dial status index digits (for example, 02, in range 1-31). Dial “*” (final part of modifier). Enter called radio address, whereupon radio displays (for example) *002*NNNNN, where NNNNN is called radio address. Press PTT or “#” to make the call, whereupon radio displays “Sending Status”.

Operation Short Data Messages The MPT1327 GOB supports Short Data Messages. To send a short data message from the menu. The full short data message string with radio address in the contact list can be predefined by the GOB CPS (e.g. “*2*Hello world!*NNNNN”, where NNNNN is called radio address). While radio in idle state, press “Menu” button to enter menu mode. Press ”Left” or “Right” button until “Contact List” displayed. Press “OK” to enter Contact List. Press ”Left” or “Right” button to choose predefined message item in contact list. Press PTT, “OK” or “#” to send the message, whereupon radio displays “Sending Data”. To send a short data message from the keypad While radio in idle state, use keypad to input “*2*” (Part of modifier). Enter short data message (e.g. ”Hello world!”) Dial “*” (final part of modifier) Enter called radio address, whereupon radio displays (for example) “*2*Hello world!*NNNNN”, where NNNNN is called radio address. Press PTT, “OK” or “#” to send the message, whereupon radio displays “Sending Data”.

Operation GPS Query The MPT1327 GOB supports GPS position query via Short Data Message. The system administrator can query an individual position by sending out a GPS query command using the special SDM format defined below. Note: Only SDMs from specified radio IDs will be treated as query SDMs. The radio ID ranges are defined by GOB CPS - check GOB CPS setting in “Edit->Common->GPS Setting” configuration window.

Operation GPS Query (continued) When the GOB receives a GPS query SDM it retrieves the GPS position info from MOTOTRBO radio GPS chip and replies with the position info using an SDM. For example, if the GPS packet data is as : GPRMC,103738,A,3044.5864,N,10357.5436,E,0.0,0.0,050607,1.3,W,A*09 Those 10 bytes data of longitude and latitude is: 0x 30 44 58 64 03 10 35 75 43 60

Operation GPS Query (continued) On receiving a GPS query, if the MOTOTRBO radio is a non-GPS radio or if the GPS feature is disabled, the GOB will respond, setting the GPS data valid flag to False. The reply SDM format is as below. Note: The TRBO radio GPS functionality can be enabled/disabled via the MOTOTRBO radio CPS.

Operation TPL Encode/Decode Support On Traffic Channel TPL Encode/Decode support on traffic channel feature can enabled/disable via GOB CPS Configure the traffic channels which have TPL enabled Open “Network-> Traffic Channel TPL Code” configuration window. Click “Add” button to add an entry and configure the related TPL setting. TPL Reverse Burst is supported to overcome the squelch tail. Once enabled, Reverse Burst shall be transmitted at the end of transmission, the duration is 150ms. Configure the MPT FFSK Pre-Time to suit for the specific MPT system Allows a duration for the base station receiver to detect the TPL and establish an audio path to the TSC. Radio commences transmitting FFSK data after pre-time has elapsed , ensuring that TSC sees start of FFSK data. Pre-time delay may not conform to MPT1327 timing spec for data on traffic channels. MPT base station needs to be configured properly to use the TPL encode/decode feature. To compliment the radio TPL encode feature the base station should only process the signalling / voice from a radio on a traffic channel if the correct TPL is decoded. To compliment the radio TPL decode feature the base station should encode the correct TPL on a traffic channel and transmit it to a radio with the signalling / voice.

Operation TPL Encode/Decode Constraint When TPL encode/decode is enabled, call include is not fully supported: When TPL Reverse Burst is disabled, inter-prefix call include does not work (note: com-prefix call include still works). When the TPL Reverse Burst is enabled, both inter-prefix and com-prefix call include do not work.   Reason for the constraint? Since the MPT FFSK Pre-Time is added between the start of the TPL and the start of the FFSK data, a conflict arises between the TPL detect performance and the MPT the timing spec (which does not consider the TPL impact). As the result, the radio subscriber can not interact with the base station correctly when initiating a call include request on the traffic channel. Does this constraint exist for legacy analog MPT models, such as GP680? Yes, this constraint exists in analog MPT radios as well.
