     DC power output 3.1.1 Connector Type The connector on the 9601 is a Samtec EHT series. This connector provides the ability for both a cable connector as well as a stackable board to board connection. For cable connected applications use the Samtec TCSD series.

  • Page 16: Connector Pin Allocation

    Iridium Satellite LLC 9601 SBD Transceiver Product Developers Guide V1.24 120505 3.1.2 Connector Pin Allocation The user connector is a 2 row 26-way latching header. Individual pin assignments are shown in Table 7. Multiple supply grounds are provided and all supply and supply grounds (pins 1-6) are required to be connected to the power supply in order to limit the current on any one pin.
  • Page 17 Iridium Satellite LLC 9601 SBD Transceiver Product Developers Guide V1.24 120505 Figure 9 provides a reference for the pin designation. Note that this designation is when looking into the multi-interface connector from above. It is not to scale and not representative of the actual connector mechanical layout.

  • Page 18: Dc Power Interface

    The DC power interface is comprised of the DC power inputs and a control signals as summarized in Table 7. The three +5V Inputs and three 0V supply returns are used to supply DC power to the 9601 and ensure that enough current can be drawn across the connector without the 9601 malfunctioning during transmit due to lack of current supply.

  • Page 19: Typical Power Profile

    Figure 11 –Typical Supply Current Profile Description: (A) Transmit burst preparation: As the 9601 gets ready to send the data burst, it turns on various parts of the transmitter chain and transfers the message into the DSP to be formatted for transmission. This first part of the pulse is nominally 170mA and lasts for 4mS.
  • Page 20 (D) Receiver data burst: The receive data burst current pulse is 14mS long, and is initially 200mA, rising to 247mA for the last 5mS, as the 9601 turns on various parts of the receiver, to capture the data burst from the satellite.

  • Page 21: Serial Data Interface

    3.3 Serial Data Interface The Serial data interface is used to both command the 9601 and transfer user data to and from the Transceiver. The 9601 presents a 9-wire data port to the FA (Field Application), where the interface is at RS232 levels.

  • Page 22: 9-Wire And 3-Wire Operation

    DCD is driven OFF at all times. Note that the Ring Indicator (RI) pin is used by the 9601 SBD Transceiver to indicate that a Mobile Terminated SBD (MT-SBD) message is queued at the Gateway. The Field Application will need to monitor this pin and use appropriate AT Commands to command the Transceiver to retrieve the MT-SBD message.

    AT&Wn command. These profiles can be designated to be loaded as the active configuration upon 9601 power-up through use of the AT&Yn command. The 9601 can be reset without loss of power to these profiles through use of the ATZn command.

  • Page 24: Modes Of Operation

     RTS/CTS flow control, if enabled, is active. When RTS is OFF (high), the 9601 suspends transfer of data to the DTE; when CTS is OFF (high), the 9601 expects the DTE to suspend transfer of data to the 9601.

  • Page 25: Dc Power Output

    3.6 DC Power Output A limited power output can be provided by the 9601 which could be used for driving an LED to provide a visible indication that the transceiver is on, or the output could be used in application logic to determine if the transceiver is on.

  • Page 26: Rf Interface

     Existing antennas will require different RF connector types to those for the 9522 and 9522A 4.1.1 Antenna Connector Type The antenna connector on the 9601 is a female SMA type. The connector is manufactured by Johnson Components and has a part number: 142-0701-871.
