Installation

General Considerations

This chapter describes the installation procedure for the unit.

Rack size

The chassis is designed to be installed in a standard 19-inch rack. The TXS 3600 occupies 1RU

of rack space. All of the cable connections are located on the rear of the unit.

Ventilation

The TXS 3600 is cooled via forced induction through the front of the unit and exhausted through

the vents in the rear. The TXS 3600 is equipped with temperature sensors to ensure operating

temperature is maintained.

Power Connection

Using the proper power connections is vital to the safe operation of the TXS 3600. Only use the

supplied power cables or one with equal specifications. The TXS 3600 can be ordered with AC

or DC Power supplies.

AC Power Connection

The TXS 3600 is capable of either operating on 120/240V 50/60Hz systems. The power supply

will automatically detect the system it is connected to. To hook up the power use the following

steps:

1. Locate the AC power cord that was included with the TXS 3600.

2. Plug the female end of the power cord (end with no prongs) into the back of the unit.

3. Locate a protected outlet (usually inside of the rack) to plug the male end of the power

cable into.

DC Power Connection

Using the proper connections is vital to the safe operation of the TXS 3600. The TXS 3600 is

intended for use in 40-70 VDC systems. The power supply will automatically detect the system it

is connected to. When installing the TXS 3600, the power supply MUST be used in

conjunction with an over-current protective device rated at 250V, 15A, type: Slow-blo, as

part of battery-supply circuit. Failure to include an over-current protective device could cause

damage to the TXS 3600, personnel, or property.

TXS 3600 - User Manual

Page 12 (58)

Rack Installation

To install the TXS 3600 into a rack use the following steps:

1. Determine the desired position in the rack for the TXS making sure that the air intake on

the front of the unit and the exhausts on the rear of the unit will not be obstructed.

2. Insert the rack mount clips into place over the mounting holes in the rack.

3. Slide the TXS into position in the rack.

4. Secure the TXS to the rack by installing the four screws through the front mounting holes

and tightening.

WARNING To prevent injury, the apparatus must be securely attached to the floor/wall in

accordance with the installation instructions.

Figure 4: Rack Mounting

Page 13 (58)

Controlling the TXS 3600 Using the Web GUI

From the web browser that is connected to the same network as the TXS 3600, type the IP

address of the unit to access the web interface. By default the IP address of the unit is set to

DHCP and can be found on the front panel. The TXS 3600 is also capable of static addressing

and accessing via host name.

Upon correctly connecting to the unit, a dialog box similar to Figure 5 should appear asking the

user to login. By default the password is left blank. Once logged on, the password can be set in

the Admin tab.

A page will load similar in appearance to Figure 6 once a user is successfully logged on.

Depending on the options of modules/features installed, small variations might be seen.

The main screen for each platform is displayed in a left-to-right fashion. This means the inputs

are shown on the left, processing in the middle section and outputs are shown on the right. The

user is capable of configuring all parameters of the transcoder from this page by clicking on the

cog which represents a settings configuration.

Figure 5: Logon Screen

Figure 6: Platform 1 Home Screen

Clicking on the triangle by each IP port allows the advanced details to be shown for the port. All

of the advanced settings are shown for the IP port in Figure 7. If changes are needed, click on

the cog to receive the settings dialog box as shown in Figure 8.

Figure 8: IP Configuration

Each input port allows the user to set a local alias for the specific port. This is a friendly name

that can be used to name the input for easy reference in the future.

The general IP settings section allows a user to enter the unicast/multicast address along with

destination port.

TXS 3600 - User Manual

Page 15 (58)

The input buffer size is settable at a range from 1 to 4,000 KB. With a larger buffer size, more

latency will be created on the input. The tradeoff with a larger buffer is possible prevention of IP

jitter and dropped packets.

The advanced settings allow source specific multicasting using IGMP v3 joins. The filter can be

set to exclude or include. IGMP addresses can be added and removed by clicking the

appropriate heading in the table. There can be up to 64 addresses entered with the highest

address taking priority over the addresses below it.

If the port is enabled and no sync is detected, an error will be indicated by a red light. Errors can

be user enabled/disabled if desired. Please see Reporting section for error details.

Figure 9: ASI Input Configuration

Figure 9 presents the ASI settings dialog for the ASI bidirectional ports. The port can be enabled

or disabled from being shown in the active list. Each ASI port allows the user to set a local alias.

This is a friendly name that can be used to identify the input for easy reference in the future.

The port can be designated as an input or output. By default, ASI I/O 1 and 2 are set as an input

and I/O 3 and 4 are set as outputs. The transport stream source is only used when designated

as an output.

In PID Lock mode, the incoming PIDs can be manually entered for the Primary or Backup Service

from the Available Services section, or an Available Service can be drag and dropped into the

Primary or Backup column allowing the PIDs to automatically fill in the appropriate column. Copy

Primary PIDs to Backup will copy all PID numbers from the Primary column to the Backup

column. The left screenshot in Figure 18 is an example of the PID Lock mode settings.

In Service Lock mode, the incoming Service Name or Program number can be manually entered

for the Primary or Backup Service from the Available Services section, or an Available Service

can be drag and dropped into the Primary or Backup section allowing the Service Name or

Program number to automatically fill the appropriate box. If AutoSeek is enabled, the transcoder

will choose the first service found in the current active input to lock to, and continue to select the

first service if the input’s content changes. Copy Primary Lock Settings to Backup will copy the

Primary Service Lock configuration to the Backup Service Lock configuration. The right

screenshot in Figure 18 is an example of the Service Lock mode settings.

The output can be configured to have the same or different outgoing PIDs from the incoming

stream. If Output PIDs Follow Input PIDs is selected, the output PID configuration will match and

follow the PID configuration set for the active input.

Each transcoder engine can support a Pass-through of up to 4 audio PIDs and up to 4

Transcoded Audio PIDs (with TXS 36480 Audio Transcoding Module installed). Each transcoder

engine also has the ability to pass up to 7 Data PIDs to the output. These types of data include

DVB Subtitles, DVB VBI, North American VBI, and DPI Messages.

Each transcoder engine also supports the creation of a PIP PMT PID and PIP Video PID (the

output PIP PCR PID will be the same as the output PIP video PID). The PIP video service will be

a simultaneous version of the main video service, rescaled to a smaller output format and

encoded separately from the main video service.

The Enabling/Disabling allows the ability to pass or block each PID.

The Language descriptor for the incoming audio PID can be set to Pass, Block, or User. The

Language descriptor can also be defined by the user.

- Pass: The language descriptor on the input will be passed to the output audio PID.

- Block: The language descriptor on the input will not be present on the output audio

PID.

- User: The user will be able to specify a three-character language for the audio

channel that will be inserted into the language descriptor on the output audio PID.
