VMU Installation, Operation and Maintenance Manual 1

Introduction

VMU Overview The OuterLink Voice Messaging Unit (VMU) adds voice messaging capability to the OuterLink Satcom system. As shown on Figure 1, the VMU provides a link between a ground vehicle or marine asset and the CommPoint device (CP-4i).

Figure 1 VMU Talk/Listen ConnectionsWhenever the VMU channel is selected at the vehicle�s audio panel, the operator can send and receive voice messages between the vehicle and the user�s dispatch center. The operator has the option of using either the Push-to-Talk (PTT) switch on his/her microphone, or the TALK button on the VMU. The CP-4i transmits the voice message via satellite to a workstation equipped with OuterLink�s CommTrack Suite 2007software.

Text messages typed at the ground station are transmitted to the vehicle via thesatellite and are converted to speech in the VMU. The arrival of a message is indicated whenever the light on the LSTN button is lit. The operator can then press the button to hear the message.

VMU Controls Figure 2 shows the controls of the VMU.

VMU Test and Checkout Procedure

Once the VMU is installed, the following tests should be performed to check its functionality.

Power Up Test Procedure 1. Place the ACTIVE/STANDBY switch to the �ACTIVE� position. Note that the switch�s backlight illuminates green in either position as power is always present.

2. Check the condition of the other switch/lights to be as follows:� MAYDAY�in down position and extinguished.� LSTN�disengaged and extinguished.� TALK�disengaged and extinguished.� COMM ALERT�extinguished.

NOTE: Prior to performing the following tests, verify that the vehicles�s Base Station is operational.

Mayday Test Procedure This procedure tests the �MAYDAY� function.

1. Place the Mayday switch to the MAYDAY position. Note that the light first illuminates amber and within 3 seconds turns green. This verifies that the Mayday message was acknowledged by the Base Station.

2. Place the Mayday switch to it�s off (down) position. Note that the light extinguishes.3. Notify the Base Station to deactivate it�s Mayday acknowledge (�MAYDAY ACK�)

capability.4. Repeat step 1. Note the following:

� that the Mayday switch light remains illuminated amber and does not turn green.

� after 30 seconds, the COMM ALERT light illuminates amber.5. Notify the Base Station to re-activate it�s �MAYDAY ACK� capability. Note that:

� the Mayday switch light illuminates green� the �COMM ALERT� light extinguishes.

Operation

Operations of the VMU

The various operational modes of the VMU are described in this section. Figure 6 shows the front panel of the VMU. The switches, buttons and their associated lights are used to perform the operational modes.

Figure 6 VMU Front Panel

Power Up Operation Connect power to the VMU. Toggle the ACTIVE/STANDBY switch to the ACTIVE position to change the VMU from standby to active mode. The switch�s backlight illu-minates green.

Two-way VoiceMessaging Operation

Two-way voice messaging may be conducted between the vehicle�s VMU Voice Panel and the Base Station�s CommSpeak software. The VMU contains both TALK and LSTN (listen) message selections. Voice messages from the vehicle are transmitted via satellite to the Base Station where they are displayed by the CommSpeak pro-gram. The Base Station transmits text messages via the satellite to the vehicle where they are converted to speech by the VMU.

Sending a Voice Message The operator can send a voice message in one of two ways:

� Use the Push-To-Talk (PTT) switch on his/her microphone.� Use the TALK button on the VMU.

To send a voice message, follow these steps:

1. Press and hold the microphone�s PTT switch, or the TALK button on the VMU.2. Speak your message.3. Release the button.

Receiving a Voice Message The operator is notified that a message has been received from the Base Station whenever the VMU�s LSTN button illuminates.

To receive a voice message, follow these steps:

1. Note that the LSTN button light is illuminated amber.2. Press the LSTN button on the VMU to hear the message.The most recent message received will be played first.

Mayday Operation In the event of an emergency, the operator can activate the Mayday function from the VMU by flipping the Mayday switch to the MAYDAY position.This automatically


Operation

transmits a �MAYDAY� message, including GPS location data, every 3 seconds to the Base Station. The Base Station then acknowledges the receipt of the �MAYDAY� message by sending a �MAYDAY ACK� message back to the vehicle. The sequence of events is described below:

NOTE: This Mayday procedure should be used, if possible, to augment your standard emergency procedures, not in place of such procedures. In particular, do NOT assume that the �MAYDAY� message has been visually acknowledged by Base Station operations. Continue to follow all standard Emergency procedures, including using voice communications as the primary mode of communications.

� The operator toggles the pull-lock Mayday switch to the MAYDAY position. The switch�s light illuminates amber.

� The �MAYDAY� message begins transmitting every 3 seconds together with GPS location data, which is continuously updated.

� Receipt of a �MAYDAY� message at the Base Station triggers an alarm thatindicates a Mayday situation and identifies the vehicle by it�s ID. A �MAYDAY ACK� message is automatically generated and transmitted back to the vehicle.

� Upon receipt of the �MAYDAY ACK� message, the VMU�s Mayday switch light changes from amber to green. The VMU will remain in the Mayday state until the Mayday switch is returned to it�s off (down) position.

NOTE: The VMU will continue to transmit the "MAYDAY" message every 3 seconds until it receives back the �MAYDAY ACK� message. If after several retries the �MAYDAY ACK� message is still not received, the COMM ALERT light will illuminate.

Standby Mode To place the VMU in the standby mode, toggle the ACTIVE/STANDBY switch to the STANDBY position. This has no effect on the operation of the CP-4i.
