- Page 17 Subject to Change Without Notice Revision 2.6 The FA board must provide a sufficient margin free of conductive elements around the 9523 perimeter in order to avoid electrical shorts with the 9523. This is indicated by the ‘SMT Placement Keepout Zone’.

Page 18: Environmental
It is expected, based on testing performed on a system that incorporates the Iridium 9523, that the Iridium 9523 would pass the tests listed in Table 4. A later revision of this document will specify which of these the Iridium 9523 has been tested to in conjunction with a test interface board that offers no protection. -

Page 22: Dc Power Supply Interface
The Iridium 9523 starts up when power is applied and the TRX_ON input is high. As long as the input voltage is applied, logic high on this line turns the Iridium 9523 on and a logic low turns it off. If this line is not required then it must be connected directly to the VBAT supply. - Page 23 The current peak in the VBOOST rail lasts for 8.3ms and repeats every 90ms (this is the period of a frame in the Iridium air interface). When not transmitting, the VBOOST current returns to zero. The VBOOST current was measured when the Iridium 9523 was connected to a 27V power source that could meet its instantaneous power requirements (around 25W).
-
Page 24: Pcm Digital Audio
3.3 PCM Digital Audio The Iridium 9523 has two 15-bit linear PCM digital audio ports, though only one of these can be in use at any time. The active port is selected using the AT+CAR command. This setup allows the FA board to provide two parallel audio paths and switch between them through software instead of hardware. -

UC_DATX PCM data input UC_DARX Note: the data signal names on Port 2 are defined from the point of view of the Iridium 9523. 3.3.3 11Hz Signal for Manufacturing and Regulatory Testing An external ‘frame tick’ signal needs to be passed to the Iridium 9523 during regulatory radio testing of the host system, and possibly also during manufacturing testing. -
Page 26: Dpl Port
The DPL port is a three-wire asynchronous serial port. It carries 8-bit, no parity data at 115,200 baud. The DPL port enables peripherals such as handsets and SIM card readers to be interfaced to the Iridium 9523. The interface utilizes an Iridium proprietary communication bus not detailed in this document. -
Page 27: Configuration Settings
The Iridium 9523 drives DCD ON to indicate that the Iridium link is active Note that the Ring Indicator (RI) pin is used by the Iridium 9523 to indicate that a Mobile Terminated SBD (MT-SBD) message is queued at the Gateway. The Field Application can monitor this pin and use appropriate AT Commands to command the Transceiver to retrieve the MT-SBD message. -
Page 28: Modes Of Operation
The inputs on the Iridium 9523 Data/Fax serial port (RTS, DTR and TXD) will operate correctly at 3.3V digital signal levels. The five outputs from the Iridium 9523 Data/Fax serial port (DCD, DSR, CTS, RI and RXD) are all at 3.3V digital levels. -
Page 29: Transmit Power Control
External GPS Receiver Switch If the Iridium 9523 is used near a GPS receiver, it is possible that the input circuitry of the GPS receiver could be damaged by the output power of the Iridium transmitter, especially if the two devices share a single antenna. -
Page 30: Rf Interface
Additional information can be found at: http://www.i-pex.com Note that the RF connector on the Iridium 9523 is not mounted directly to the FA board along with the user interface connector. It must be attached to the FA board through a coaxial cable. -
Page 31: Radio Characteristics
RF component between the Iridium 9523 and the antenna should not exceed 3 dB. Implementation loss higher than this will affect the Iridium link performance and quality of service. Solutions with a loss higher than 3 dB will not meet the requirements of Iridium Solution Certification. -
Page 32: At Interface
Some extended commands have a single execution mode. No further syntax is added after the prefix and body of the command. For example, AT+GSN is entered as shown to query the Iridium 9523 for its assigned serial number (i.e. IMEI). -

Page 34: Command Entry
5.5 Command Entry An AT command is a string of characters sent by the FA to the Iridium 9523 while it is in command mode. A command string has a prefix, a body, and a terminator. The prefix consists of the ASCII characters AT or at. -

It will be sent whenever there is a non-data call state change in the Iridium 9523’s internal Call Control (MMICC) state machines, including during a voice call session (possibly with multiple concurrent calls) when any call becomes held/active/waiting.
