the message. In this case Network Available will not come on immediately. The Network Available does not
turn on while in a +SBDI session. It will however turn on 4 seconds later assuming that the Ring Channel is
present. After the SBD session completes, the 9602/9602N performs a new Ring Channel search sequence, at
the end of which Network Available gets turned on. That can take between 4 and 12 seconds.
The wait time between search windows is reset to 4 seconds every time a search succeeds. Otherwise it
continues to increase. So if the +SBDI attempt fails to find the ring channel, the search window does not reset
to 4 seconds.
Note that the behavior of +CIEV:1 is identical in to that of the Network Available output.
3.6 DC Supply Indicator Output
A DC supply indicator signal is provided by the 9602/9602N which could be used directly for driving an LED to
provide a visible indication that the Transceiver supply is on. Alternatively the output signal could be used in
application logic to determine if the internal Transceiver power supply is on.
4 RF Interface
This section describes the physical characteristics of the RF connectors and specifications of the RF Interface.
4.1 RF Connector Types
When mating to the 9602/9602N RF connector use MMCX male connectors from SAMTEC part number MMCX-P-
P-H-ST-TH1. This is a thru hole printed circuit mount connector with the correct mechanical spacing to allow
the 9602/9602N to fit flush on the motherboard
Note - this 9602/9602N module has a different antenna connector than Iridium transceivers.
Both RF connectors on the 9602/9602N module are intended for an inter-board connection to the host system
motherboard and should not be directly connected to an external antenna cable or cable distribution system.

4.2 ANT Connector
The main RF connector for the 9602/9602N is the antenna connector, labeled "ANT" in the board silkscreen.
This provides the RF connection between the 9602/9602N module and the host system motherboard.
Note that for safety reasons, both RF connectors on the 9602/9602N module are intended for an inter-board
connection to the host system motherboard and should not be directly connected to an external antenna cable
or cable distribution system. The EN609502 compliance standard outlines that telecommunications equipment
needs protection from a 2KV spike.
protection needs to be provided on the developer's motherboard and a larger connector needs to be used.
Developers are encourages to review the EN609502 compliance standards for additional details.
