AMX design xpress home theater v1.3 ユーザーガイド

The options in the Control Configuration tab (FIG. 4) allow you to configure the AMX IR port to 

properly transmit the IR signal to the AV equipment. This tab requires that you know how your 

equipment operates.

 

IR Timing Parameters (1/10 second) - Sets the IR pulse times and the time gap between 

pulses. The default time is .5 seconds. Occasionally, this pulse time is too long and results 

in two commands being sent. This is most evident on numeric keypads and menu cursor 

controls. Use the up/down arrows to adjust the values, or enter new values directly into 

the text fields (range = 0 - 255, in 1/10 second increments).

 

IR Pulse Time - the length of time the IR signal is on and is being transmitted 

(CTON).

 

Time Gap Between IR Pulses - the length of time between IR pulses. This is 

usually used only in macro functions (CTOF).

 

Tune Using XCH Command - XCH Send_Commands are used to recall station presets 

for the TV Tuner, VCR and DSS. Different manufacturers require the channel numbers to 

be entered differently. Select the mode that matches your equipment. When this option is 

selected, the following XCH Modes are available. Select the mode you want to use with 

this device:

• Mode 0

The resulting IR for the Send_Command ’XCH-3’ would be: 3-Enter.

• Mode 1

The resulting IR for the Send_Command ’XCH-3’ would be: 0-0-3-Enter.

• Mode 2

The resulting IR for the Send_Command ’XCH-3’ would be: 0-0-3.

• Mode 3

The resulting IR for the Send_Command ’XCH-3’ would be: 0-3.
