Please retain the shipping carton and allof the packing materials and use them to ship the unit to a final destination or to return the unit to Tiernan for repair. Repacking instructions are listed in the following section.

About the TDR7 Shipping Cartons and Packing Materials

Equipment Repacking Instructions

To repack the TDR7 for shipment to another location or to return the unit to Tiernan for repair, please use the original shipping carton and packingmaterials. Before youbegin torepack the equipment,perform the following inspections:

1. Inspect the shipping carton to ensure that it does not have any holes punched through itand thatallfour sidesare sturdy andare firmly attached to the adjacent walls, top, and bottom of the carton.

2. Ensure that both specially designed suspension frames are available for use in repacking the equipment. The suspension frames look like a cardboard frame with a sheet of clear plastic stretched over the opening.

3. Inspect the two suspension frames to ensure that the cardboard framesare in onesturdy piece, andthe plasticis not torn orri pped apart from the frames.

4. If you believe the carton or packing materials will not properly protect the equipment during shipping, contact Tiernan Communications Product Support.

CAUTION: Carefully Follow the Repacking Instructions

CAUTION!

Please Read

Carefully

If thesuspension frames are notpacked into the shipping carton as instructed below, the equipment may be severely damaged during shipping and handling.

xvi

Introduction

If you believe the carton and packing materials will properly protect the equipment during shipment, repack the equipment following the instructions listed below.

1. Place the first suspension frame into the shipping carton with the plastic film side facing up and away from the bottom of the shipping carton. The plastic attached to the suspension frame mustnot be touching the bottomof the shippingcarton. When the equipment is placed into the shipping carton, the equipment should be suspended on the top of the plastic. If the first suspension frame is placed inthe shipping cartonwith the plastic film against thebottom of the shipping carton, theequipment will rest on thebottom ofthe shippingcarton andw ill notbe protected from shocks and vibrations.

2. Place the equipment into the shipping carton and onto the center of the plastic suspension frame.

3. Place the second suspension frame into the shipping carton with the plastic film side facing down towards the top of the equipment. The plastic attached to the suspension frame must be placed against the top of the equipment, so that the equipment is fully suspended between the first suspension frame and the second suspensionframe. When you place the second suspension frame on top of the equipment, the second suspension frame will extend higher than the top edge of the shipping carton; however, when you close the carton, the second suspension frame will easily fit into the carton. The pressure applied to the second suspension frame will help hold the equipment in place between the two suspension frames.

4. Close the carton, and reseal the carton with adhesive tape. Once the carton is sealed, the packing materials create tension around theequipment that holdsthe equipmentsecurely between thetwo plastic sheets and safely away from shocks and vibrations.

Option Modules

To expand its operational capabilities, the TDR7 chassis contains one slot for an option module. Two option modules are available which allow the TDR7 to provide either teletext or digital video with embeddedASE/EBU audio channels.Thetwo modulesare descri bed below.

TTO–6000

Option Module

In the PAL video mode, the TTO–6000 allows the TDR7 to process teletext data contained in a selected service provided by any encoder that supports DVB–compliant teletext.Teletextdata is providedin the composite video output without impacting the speed at which PGCA messages are processed. Teletext data parameters are configurable from the control front panel using an added menu or from a remote control device using configuration commands.

Interfaces

TEA–6000

The TEA–6000 allows the TDR7 to insert up to four independent AES/EBU audio channels into the horizontal ancillary data space of the digital video stream. The TEA–6000 provides this functionality automatically without need for special setup or configuration.

Installing a Remote Control Device

The remote control port is a female DB–9 connector that provides a half–duplex RS–232 interface to the TDR7. Remote control may be accomplished using either a stand alone computer with an asynchronous communications software application installed or a network management system host computer with a bisynchronous communications protocol. Both the asynchronous and the bisynchronous communications protocolsare embeddedin theTDR7 firmware,which allows the TDR7 to automatically sense and use the appropriate communications protocol based upon the input signal.

In addition to the control front panel, you can use a remote control device(RCD)to perform configurationand monitoringfunctions.The

RCDmay be an ASCIIcomputerterminal, a personal computer,or any other control device capable of asynchronous communications at RS–232 electrical levels. The RCD provides full duplex operations with the TDR7 so that whenever you type a keystroke on the RCD, it issues an asynchronous ASCII character to the TDR7,andtheTDR7 echoes that character back to the RCD display.

RCD Commands

RCD commands begin witha command mnemonic that abbreviatesa TDR7 functional block. For example, the command mnemonic DC is the Decoder Controller functional block. To set one of the Decoder Controller parameters, typeDCfollowed by a space and then type a mnemonic that abbreviates the parameter. For example, the execute command required to select PID 12 for audio channel B follows:

DC_ADB_PID_12

Some mnemonics are also represented as a number, which can be entered in the place of the mnemonic within the command. When entering commands at the RCD, enter either the mnemonic or its numerical equivalent, not both. For example, to send a query command to view the list of audio PIDs available in channel A using a numerical equivalent of a mnemonic, enter the following:

DC_ADA_1

NOTE: Numerical Equivalents for RCD Commands

In the lists of commands that follow, the numerical equivalents of mnemonics, where available, are shown in parenthesis after the mnemonic. Don’t enter the parenthesis; enter only the number.
