79066 User Manual
3. Operation
3.1 Front Panel Buttons
From the front panel, the TPHD2-WP1 is controlled by pressing the Source/Auto button or through
the RS232 port. Both automatic and manual switching between HDMI & VGA are supported. By
default, the TPHD2-WP1 is set to auto-switching, and the button is illuminated. To set the unit to
manual switching, press and hold the Source/Auto button for 3 seconds or more or send the RS232
command “40771%”. Once the button light is off, the unit can be toggled between HDMI and VGA by
pressing the button. To set the unit back to auto mode press and hold the button for 3 seconds or
more or send the RS232 command “40770%”.
•
Automatic Switching Mode
In this mode the Source/Auto button is lit up green, and the TPHD2-WP1 switches to the last
connected source automatically. If two sources are connected and one is disconnected, the
unit will switch to the original source. Otherwise the unit will not switch.
•
Manual Switching Mode
In this mode the Source/Auto light is off, and the user must press the button or send an RS232
command to switch between sources. Pressing Source/Auto toggles between HDMI and VGA,
and the indicator of the currently selected source will light up green. To switch between HDMI
and VGA using RS232 commands send
“40701%” for HDMI and
“40704%” for VGA.
3.2 RS232 Control
3.2.1 Wall Plate Control
TPHD2-WP1 can operate in one of two control modes for RS232 control. These two modes allow the
RS232 connection at the wall plate to control a far-end device, or for the far end device at the
receiver to control the TPHD2-WP1.
•
Passthrough Control Mode
In Passthrough Control Mode, RS232 data can be sent to control a far end device. Use this
mode to allow a TekTouchPad to control a controller or display.
Bi-directional RS232 data can be sent between the wall plate and a compatible HDBaseT
receiver to support control of a controller, or to send commands directly to a display.
Supported baud rates are: 2400, 4800, 9600, 19200, 38400, 57600 or 115200.
•
Far-End Control Mode
In far-end control mode, a control system can control the TPHD2-WP1.
3.2.2 Wall Plate Operation
An RS232 utility program or dedicated controller is necessary to send commands to the wall plate.
The commands cannot be sent using a terminal program as one character at a time, and must be
sent as a group of characters.
