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.
Additional information can be found at: http://www.samtec.com
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. The MMCX connectors are not
capable of 2KV operations therefore 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.
