TEK 51T-HD Compact Presentation Switcher

TEKVOX, INC. 6 www.tekvox.com

4) All devices should be connected before powering the unit on.

3.2 System Diagram

3.3 Connection Procedure

Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of TEK

51T-HD with HDMI cable. Connect VGA source device (e.g. PC) to VGA input

ports of TEK 51T-HD with VGA cable.

Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT

port of TEK 51T-HD with audio cable one to one. The audio of HDMI can be

embedded or external by sending RS232 command.

Step3. Connect HDMI display device to HDMI output port of TEK 51T-HD with HDMI

cable.

Step4. Connect TEK TPHD402PR to HDBaseT output port of TEK 51T-HD with Cat 5e

or Cat 6 type cable.

Step5. Connect speaker, headphone, or amplifier to AUDIO OUTPUT port of TEK

51T-HD.

Step6. Connect control device (e.g. PC) to RS232 port of TEK 51T-HD or TEK

TPHD402PR (bi-directional RS232 control, either is available).

TEK 51T-HD Compact Presentation Switcher

TEKVOX, INC. 7 www.tekvox.com

Step7. Both TEK 51T-HD and TEK TPHD402PR have IR IN and OUT. When one model

is used for IR signal receiver, the IR signal must be sent out by the other model.

For example: When “IR IN” of TEK 51T-HD connects with an IR receiver, the IR

transmitter must connect to IR OUT of TPHD402PR.

The IR signal can be transmitted bi-directionally between TEK 51T-HD and

TEK TPHD402PR.

Step8. Select MIC level and connect right microphone to MIC input port. MIC audio will

be transmitted to AUDIO OUTPUT port and mixed with source audio.

Step9. Connect DC12V power adaptor to the power port (TEK TPHD402PR is able to

get power from TEK 51T-HD).

3.4 Connection of Microphone

TEK 51T-HD provides one 3-level microphone input to accommodate different

microphone input modes, including 48V phantom power mode, MIC mode, and LINE

mode.

 48V phantom power input

When switched to “48V”, the MIC input provides 48V phantom power. This is only used

for the condenser microphone.

Connection is: “+” connects to positive, “-” connects to negative and “ ” to ground.

 MIC input

When switched to “MIC” (low frequency characteristics and wide frequency response in

this mode), the microphone input is used for connecting with the dynamic microphone.

There are two different connections:

1) Unbalanced connection:

“+” and “ ” connect to ground, and “-” connects to signal.

“-” and “ ” connect to ground, and “+” connects to signal.

TEK 51T-HD Compact Presentation Switcher

TEKVOX, INC. 8 www.tekvox.com

2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”

connects to ground.

 LINE input

When switched to “LINE” (low frequency characteristics and wide frequency response in

this mode), the microphone input is used for connecting with line audio or wireless

microphone output. There are two different connections:

 Unbalanced connection:

“+” and “ ” connect to ground, and “-” connects to signal.

“-” and “ ” connect to ground, and “+” connects to signal.

b) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”

TEK 51T-HD Compact Presentation Switcher

TEKVOX, INC. 9 www.tekvox.com

connects to ground.

3.5 Application

The TEK 51T-HD is ideal for smaller system applications especially when there is no

need for an equipment rack. The switcher can be mounted under a conference table, on

a wall, or in a teacher’s desk. When used with a TEKVOX Drop-In system, a low cost

and complete mediated classroom system can be created.

4. System Operations

4.1 Operations of Buttons

The buttons are used for output resolution adjusting, switching operations, Firmware

updating, volume adjusting and operations in menus.

Resolution Adjusting 4.1.1

Resolution can supports both auto and manual settings. Press and hold the

RESO/AUTO button for 7 seconds or more to enter into

auto-adjusting/manual-adjusting mode.

Notice:

1. In auto-adjusting mode the TEK 51T-HD uses the EDID of the display to set the

resolution.

If you need to set the resolution of local HDMI display device:

 Power off the TEK 51T-HD and break the connection between the TEK 51T-HD and

TEK TPHD402PR.

 Turn on the power for the TEK 51T-HD.

 Get the resolution of local HDMI output device.

 Connect the TEK TPHD402PR to TEK 51T-HD.

2. In auto-switching mode front panel button control is not available, but IR and RS232

control is able to switch modes.

TEK 51T-HD Compact Presentation Switcher

TEKVOX, INC. 10 www.tekvox.com

Switching Operations

4.1.2

The TEK 51T-HD Supports both auto-switching and manual switching. Press and hold

the SOURCE/AUTO button for 7 seconds or more to enter into

auto-switching/manual-switching mode.

The display result is showed as below:

The display result will be shown for 2 seconds.

The auto-switching mode follows the listed principles:

 New input principle

Once it detects a new input signal, the TEK 51T-HD switches to this new signal

automatically.

 Power rebooting principle

TEK 51T-HD offers this feature to remember the last displayed signal when

rebooting. While rebooting, the TEK 51T-HD automatically enters into auto-switching

mode and detects all inputs to memorize their connection status.

If the signal last displayed is still available, then it will choose the signal to output. If

not, there will be no signal on its outputs.

 Signal removing principle

Once it has removed the current display signal, the TEK 51T-HD will detect all input

signals with priority from INPUT 1 to INPUT 5. It will select the first detected signal to

its output.

Notice: The Auto-switching function works only when an input detects a new signal, loss

of a signal, or power rebooting. With any VGA port set to AV or YPbPr the system is not

able to enter in Auto-switching mode.

4.3 Operations of CEC Function

The TEK 51T-HD supports CEC commands and can be enabled and disabled through

RS232 commands or the OSD menu. If the HDMI source device supports CEC and its

CEC operation is enabled when the TEK 51T-HD enters in standby / startup mode, then

the source device will automatically enter standby / startup mode.

Devices that support CEC functions can be controlled with basic operations (play, pause,

fast forward, fast reverse, menu, etc.). Users are able to control the TEK 51T-HD and

HDMI source device via the IR remote or RS232 commands from the TEK 51T-HD. Note

that not all CEC enabled devices operate the same and may act differently between

devices.

Commands for CEC function: “50686%” (enable CEC) and “50687%” (disable CEC).
