Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 2.3 Environmental The environmental specifications of the 9601 are summarized in Table 5 below. Table 5: Environmental Specifications Parameter Operating Temperature Range Operating Humidity Range Storage Temperature Range Storage Humidity Range Value -30ºC to + 60ºC ≤75% RH -40ºC to + 85ºC ≤93% RH The 9601 has been tested to the specifications listed in Table 6.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 3.0 Electrical Interfaces The subsections to follow contain information for the electrical interfaces of the 9601 Transceiver. 3.1 Multi-Interface Connector The multi-interface connector includes six interfaces: DC power supply input Power on/off control RS-232 Serial data Network available output DC power output 3.1.1 Connector Type The connector on the 9601 is a Samtec EHT series.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 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.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 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. 02 26 01 03 25 Connector notch Figure 9: Multi-Interface Connector Pin Number Designation Notes: 1. 2. 3. 4. 5. 6.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 3.2 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. Note that all six pins should be connected.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 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. With respect to this interface, the Data Module behaves as a DCE (Data Communication Equipment), and the FA behaves as a DTE (Data Terminal Equipment).
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 Note that the Ring Indicator (RI) pin is used by the 9601 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. The serial interface may be operated with a 3-wire connection, where only transmit, receive and ground signals are used.
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 3.3.3 Modes of Operation The serial interface is always in one of three modes: command mode, SBD data mode or SBD session mode. When the data port is in command mode, AT commands can be entered to control the Data Module. In command mode, flow control has no effect, with the RTS input ignored and the CTS output driven ON (low).
Iridium Satellite LLC 9601 SBD Transceiver Preliminary Product Developers Guide V1.2 082905 4.0 RF Interface This section describes the physical connector and RF specifications of the RF Interface. 4.1 Antenna Connector The 9601 will have the following antenna connector characteristics as described in Table 10.

Iridium Satellite LLC 9601 Transceiver –AT Command Reference where is: 0 Network service is currently unavailable. 1 Network service is available. Network service availability is equivalent to a signal strength greater than 0. The service availability indicator provides a way for the FA to wait until the 9601 can start an SBD session without receiving continual notifications of changes in signal strength.
Iridium Satellite LLC 9601 Transceiver –AT Command Reference Note: The DTE may initiate an SBD session even if service is unavailable; in this case, the 9601 makes an immediate search for the network and, if successful, starts the SBD session, otherwise the SBD session fails. 2.22 +CSQ –Signal Quality Exec Command: +CSQ Execution command returns the received signal strength indication from the 9601.

The change in data rate takes into effect after the result code (e.g., OK) is received by the DTE.
Iridium Satellite LLC 9601 Transceiver –AT Command Reference This command is used to transfer a binary SBD message from the DTE to the single mobile originated buffer in the 9601. The mobile originated buffer can contain only one message at any one time. Once the command is entered, and the message length is acceptable, the 9601 will indicate to the DTE that it is prepared to receive the message by sending t heASCI Iencodedst r i ng“ READY”( hex52454144590D0A)t ot he DTE.
