The VAM controller board takes care of the external interfaces from the user to VAM-CM and is responsible for VAM CM modem control. Figure1shows an example architecture of a VAM terminal including the VAM-CM, VAM controller and basic interfaces. The VAM-CM interface is described in more detail in VAM-CM interfaces on page 11. DRAFT Figure 1. VAM Terminal Architecture 3.2: VAM-CM Concept The target of VAM concept was to produce small GMR 2+ modem with simple cost effective RF and control interfaces. The VAM-CM design shown in Figure2is optimized from the IsatPhone 2 platform design by excluding non-necessary handset related interfaces and features, by including industry standard board to board interface connectors and by optimizing the PWB area consumption. 6:GSPS Core Module 2.0 VAM-CM HW Description Confidential and Proprietary Inmarsat Global Limited inmarsat.com 3: VAM-CM Overview Figure 2. VAM-CM Due to the simple and compact interfaces, testing and evaluation of the VAM-CM requires interface extension to enable easier access to control and indication signals. The VAM-CM Evaluation Module available from Inmarsat provides easier and more convenient interfacing to the VAM-CM during terminal test and evaluation phases.

A VAM terminal can determine the interface voltage level by applying the desired V_io voltage to the VAM control interface connector. Voltage requirements for logic levels are shown in Table2. For more details, see Power Supply interface description on page 16. The VAM control interface is a combination of digital and analog baseband interfaces dedicated to control the VAM-CM. The Interface also includes other user interface related signals like USIM and audio. The VAM control interface is a Harwin M50-360-25 42 male type pin header connector.

This interface is targeted for firmware updates and direct VAM-CM controls. The system USB connector shall be routed out from VAM terminal for direct access. The system USB interface can also be used for VAM-

CM control when USB mode is selected with VAM Boot selector during VAM-CM power-on. The VAM can put CM in low power mode by sending USB suspend command and wakeup is initiated by sending resume command.

More detailed information about communication mode settings can be found in StandardandProprietaryATCommands. The UART control bus is equipped with level shifter in VAM-CM board. This solution enables VAM to adjust I/O voltage system by applying own V_io voltage to VAM control interface connector. Voltage requirements for logic levels are shown in Table2. More details in chapter Power Supply interface description on page 16. UART control interface uses protocol with 8 data bits and 1 stop bit. Parity bits are not used in UART communication.

For more details, see Power Supply interface description on page 16. DRAFT Two modes are available for the PCM protocol: mode 1 and mode 2. For both modes, there are two types of operation: mono and stereo channels. The difference between PCM mode 1 and PCM mode 2 is in the way they use either the rising or the falling edge of the clock signal, and the frame-

synchronization polarity.

> PCM Mode 1: Input data is latched on the falling edge of the clock, and the transmitted data starts on the rising edge of the clock. Frame-synchronization pulse is active high.

> PCM Mode 2: Input data is latched on the falling edge of the clock, and the transmitted data starts on the falling edge of the clock. Frame-synchronization pulse is active low. Figure7and Figure8shows an example of PCM protocol, mode 1 and mode 2, respectively, for a frame composed one word (width: 32 bits) with 16 bits data. More detailed information concerning PCM interface can be found in TexasInstrumentsDM3725 documentation. Figure 7.

PCM Protocol Mode 2 Data Format 4.2.6:Power Supply interface description The Power supply interface contains multiple pins to share high current flow of one pin to several pins. Additional grounding pins are spread out for different sub-interfaces. Digital interfaces to VAM-CM processor (DM3725) are connected via level shifters. VAM terminal can determine the interface voltage level by applying interface voltage in V_io pin (#15) of VAM-CM system connector. V_io can be selected between 1,65V 5,5V.

Ext Vrtc supply input is however included in VAM system interface to allow possibility to feed external back-up voltage for VAM-CM to enable warm start in case of long term cut off of 3v9 Supply. Internal buffer capacitors in VAM-CM will maintain back-up voltage for 10 seconds which is meant to keep up back-up operation during short 3v9 supply cut-offs. 16:GSPS Core Module 2.0 VAM-CM HW Description Confidential and Proprietary Inmarsat Global Limited inmarsat.com Pins

"0,51s LOW pulse" Turns modem on or off depending of current state. Back-up voltage is internally supplied in VAM-CM meaning that if 3v9 Supply is available for VAM-

CM, also internal back-up voltage is present. Powering off the VAM-CM does not shut down internal back-up voltage supply. Omission of Ext Vrtc supply has influence only in case that 3v9 Supply is cut off for some reason. Back-up voltage keeps on the slow clock (32kHz), RTC date information and GPS satellite status information. When back-up voltage goes down this information is lost and VAM-CM needs to make cold start which will add about 35 seconds (GPS fix, TTA calculation) to warm start time. 4.2.8:Control and ID interface description The Control and ID interface is provided to set dedicated operating modes for VAM-CM for different use cases. These modes can be related for boot-up or control mode. Control and ID interface is connected via level shifter circuit which allows VAM terminal to determine the signal voltage level using V_io pin in VAM-CM system connector (Table8). Power on/off control is not connected via level shifter to enable powering up the VAM-CM when level shifters are not active.

This solution enables VAM to adjust I/O voltage system by applying own V_io voltage to VAM control interface connector. For more details, see Power Supply interface description on page 16. Power on/off is not controlled via level shifter. Power on/off is pull down type control having internal pull-up resistor for "HIGH-state" implemented in VAM-CM board. Power on/off action is achieved by pulling this line to GND so no level shifting is needed. Power on/off line shall be floating when inactive, no external pull-up is allowed. 4.3: Radio interface description 4.3.1:GMR2 transceiver antenna interface Dedicated antenna interface for GMR2 transceiver.

This is required to put CM in low power mode to reduce CM power consumption. 4.4.0.1:VAM-CM USB interface PM Handling In the VAM-CM USB control interface, core module (CM) supports USB suspend/resume feature as per USB2.0 standards to put in low power mode. By default low power mode is disabled in CM and CM can be put into low power mode based on USB suspend signal and wakeup based on resume signal, seeReferences on page 5 section 7.1.7.6 and 7.1.7.7. Without handling USB suspend/resume the CM will not enter low power mode and hence overall current consumption will be more. It is recommended that the VAM should implement USB suspend/resume feature to put CM in low power mode and wakeup from low power mode. DRAFT In VAM-CM UART control interface, core module (CM) low power mode (sleep) is by default enabled and VAM can get sleep state and wakeup from sleep state using VAM_CM_SLEEP and VAM_CM_ WAKEUPsignals. VAM can check CM sleep state using VAM_CM_NSLEEP signal, high=Active and low=sleep. VAM need to check VAM_CM_SLEEP signal before sending any data to CM and if this signal is low then set VAM_CM_WAKEUPsignal high for 100mSec to wakeup CM and ready to process data. See Table9for Sleep and Wake-up signal details. Mechanical dimensions and mounting points are shown in Figure11- Figure13. VAM-CM can be mounted with four 2,5mm screws from the module corners. 5mm extension towers are required to mount VAM-CM so that tightening the screws does not introduce any forge to components and shield can soldered on the board. 4.5: Mechanical interface Figure 11.

In many vehicles, the door seals are sufficiently pliable that they will not damage the cables when the door is closed. For added cable strain relief, use the provided cable tie to firmly secure the short RF cables on the clip adapter to the clip adapter body. 4.4 Affix RF cables to clip with cable tie 4.6 Insert phone into clip 4.5 Connect 1.5m RF cables to clip adapter When connecting cables to the clip adapter, care needs to be taken to connect to the correct ports: match the cable connected to the GPS port on the antenna to the GPS port on the clip. And likewise, match the cable connected to the ISAT port on the antenna to the ISAT port on the clip. If the cables are inadvertently cross-matched, there will be no signal bars on the phone when it is powered up. Check that the cables match the antenna and clip ports end-to-end. Insert the phone into the clip as follows:

1. Open rear connec-

tor access panel
