    Added DSP RomDB Version to Class 2, Subclass 1 (Table 19)  Minor updates throughout Purpose This document describes the behavior and interfaces of the IDP 100 series of modems. The primary modem serial interface is the AT command interface implemented in the modem. Audience This document is for technical readers.

  • Page 10: Reference

    IDP 100 Modem Series - Developer Guide An OEM Integrator is a SkyWave customer who purchases an IDP 100 series modem for integration into their own enclosure. In order to become an OEM Integrator certain commercial criteria must be met. Contact your Account Executive for further details.

  • Page 11: Introduction

    IDP 100 Modem Series - Developer Guide 1 Introduction The IDP 100 series are IsatData Pro satellite modems. Each provides satellite messaging for a host application. The modem's primary interface is the AT command. Using AT commands, a host can configure, control and exchange data with the IDP modems. The modems' AT commands are based on the ITU-T Recommendation V.250.

  • Page 13: Modem Overview

    The modem suspends all from-mobile messages if a beam switch is pending. If either a from-mobile or a to-mobile message is in transmission prior to a beam switch, all subsequent retries are transmitted on the new beam. © SkyWave Proprietary T203, Version 04...

  • Page 14: Blockage

    When muted, the modem may still transmit modem registration and beam notification messages. 2.2 Message States Figure 2 illustrates the message states for both from-mobile and to-mobile messages. © T203, Version 04 SkyWave Proprietary...

  • Page 15: To-Mobile States

    A to-mobile message can be repeatedly retrieved until it is overwritten. 2.2.1.1 Rx Completed The host only knows about messages that have completed and gone to the Completed state. The host is not notified when a to-mobile message fails. © SkyWave Proprietary T203, Version 04...

  • Page 16: From-Mobile States

    If a from-mobile message is received before the message registers on the network, the message is added to the transmit queue. The message stays in the queue indefinitely. Once the modem receives a valid signal and registers, if required, it starts to transmit the message. © T203, Version 04 SkyWave Proprietary...

  • Page 20: Satellite Messages

    The modem solely manages how it allocates messages to individual message partitions. As such, the modem does not report the partition where messages are stored, and it does not report the amount of available memory in any given partition. © T203, Version 04 SkyWave Proprietary...

    The trace records are intended for advanced modem users to help them diagnose problems with the assistance of SkyWave Customer Support. The trace records can be extracted from the trace table using either AT commands or by going into trace log mode.

These are message types host applications can use to send and receive data over the IsatData Pro network.
