NAL RESEARCH 9602-NAL Iridium Satellite Communications Modem User Guide

NAL RESEARCH 9602-NAL Iridium Satellite Communications Modem

Product Information

The 9602-NAL is a device designed for transmitting and receiving messages from the Iridium network. It features a DB-15 Multi-Interface Connector for data communication and an Iridium SMA Antenna Connector for connecting the recommended SYN7391-C antenna. The device also has a DC Power Input interface that accepts either +5 VDC or +6.5 VDC to +32 VDC input.

DEVICE DESCRIPTION

The 9602-NAL modem is a satellite transceiver comprising an Iridium 9602 transceiver with an extended input voltage range, that allows SBD connectivity to the Iridium satellite network. It does not support voice, circuit-switched data, or Short Message Service (SMS). The 9602-NAL can be controlled by a DTE capable of sending standard AT commands via an RS232 serial port. The 9602-NAL is equipped with four mounting holes, one at each corner. It is recommended to use 6-32 screws to fasten the modem down.
IMPORTANT: The 9602-NAL antenna must have a full view of the sky during transmission

• DB-15 Multi-Interface Connector
  

  • The DB-15 Multi-Interface Connector is a male 15-pin miniature D-sub type that allows the device to transmit and receive messages from the Iridium network.

• RS232 Data Interface
  

  • The RS232 Data Interface enables a connected DTE (Data Terminal Equipment) to utilize the modem functionality of the 9602-NAL through standard AT and extended sets of AT commands.

• Iridium SMA Antenna Connector
  

  • The Iridium SMA Antenna Connector is used to connect the recommended SYN7391-C antenna to the device. It is important to ensure that the antenna has a full view of the sky during transmission.

• DC Power Input
  

  • The DC Power Input interface consists of two DC power inputs, a ground input, and a control signal. The device accepts either +5 VDC input through pin #1 or +6.5 VDC to +32 VDC input through pin #2. By default, the device is set for +6.5 VDC to +32 VDC input, but it can be changed to +5 VDC input through an internal jumper.

Product Usage Instructions

1. Ensure the modem is turned off before proceeding.
2. Connect the antenna connector to the Iridium connector port on the device.
3. Verify that the antenna has a full view of the sky.
4. Check the cable loss between the modem and antenna to ensure proper signal transmission.

DEVICE DESCRIPTION (continued)

• Antenna: NAL Research recommends the SYN7391-C antenna.

• CAUTION: Do not or disconnect the antenna while device is powered.

• DC Power Input: The DC power interface comprises two DC power inputs, a ground input, and a control signal. The 9602-NAL accepts either +5 VDC input through pin #1 or +6.5 VDC to +32 VDC input through pin #2. The 9602-NAL is shipped with hardware set for +6.5 VDC to +32 VDC input. It can be changed to +5 VDC input through an internal jumper.

• Change Input Voltage to +5.0 VDC (Optional)
  CAUTION: DISCONNECT POWER BEFORE RESETTING THE JUMPER

  • Turn off the modem.
  • Remove the plate to locate the jumper.
  • Set the red jumper to the desired voltage range:
  • Left and center pins for an input voltage of 5 VDC.
  • Center and right pins for 6.5 VDC to 32 VDC input.

Note: For further configuration and operation instructions, please refer to the complete user manual.

CONFIGURE DEVICE TO OPERATE

1. Turn off modem.
2. Connect the antenna connector to the Iridium connector port on the device.
3. Verify the antenna has full view of the sky and the cable loss between the modem and antenna is <3 dB.
4. Connect a DTE to the DB15 port on the device using the HRC-24-11 Data/Power Cable Assembly.

CONFIGURE DEVICE TO OPERATE (continued)

1.  Supply DC power through pin 1 (+5 VDC) or pin 2 (+6.5 VDC to +32 VDC) and pin 3(EXT_GND).
2.  Configure the 9602-NAL using AT commands (SatTerm).
