Remotely managing your display

Connect a computer to the display’s room control input to remotely select video inputs, turn on or turn off the display and access the display’s settings.

To connect a computer to the display

1. Connect a DB9F to DB9F (a D-sub with 9 female contacts) null modem cable from the computer’s serial output to the room control input on the display’s connector panel.

   This table describes the cable’s wiring and connectors:

   Connector 1	Connector 2	Function
   1	N/A	(not used)
   2	3	Receive data
   3	2	Transmit data
   4	6	(not used)
   5	5	Signal ground
   6	4	(not used)
   7	8	(not used)
   8	7	(not used)
   9	N/A	(not used)

To configure the computer’s serial interface

1. Turn on the display.

2. Turn on the computer, and then start the serial communications program.

3. Activate local echo.

4. Configure the serial interface settings using the following values, and then press ENTER.

   Setting	Value
   Baud rate	9600
   Data length	8
   Parity bit	None
   Stop bit	1

   A command prompt appears on the following line.

   Note 

   If no message appears or an error message appears, the serial interface configuration isn’t correct. Repeat steps 3 to 4.

5. Type commands to configure the display.

You can assign settings or access the display’s current settings.

To assign or access display settings

1. Type a command after the command prompt in the room control system, and then press ENTER. If you’re identifying a setting, wait for a response from the display.

   Note 

   Many serial communications programs require that you insert 0x in front of the hexadecimal value. The examples in this section already have the 0x values included in the command.

   Example 

   To turn off the display, use the following command: 0x35 0x62 0x30 0x30 0x31 0x30 0x30 0x30 0x30 0x30 0x0D.

   If you type the command correctly, the display will turn off and you won’t receive a response. If the room control system doesn’t recognize the command, the system will respond with the same command that you entered.

   Example 

   To identify the display’s power status, use the following command: 0x35 0x38 0x30 0x30 0x32 0x30 0x30 0x0D.

   The display will respond with a command. Compare the command to the table of command responses below. If the room control system doesn’t recognize the command, the system will respond with the same command that you entered.

   NoteS

   • Use hexadecimal formatted commands.

   • Commands aren’t case-sensitive.

   • Review each entry carefully before you press ENTER.

Use the following command to access the display’s power state 0x35 0x38 0x30 0x30 0x32 0x30 0x30 0x0D.
