DXP-HT v1.3 - Programmer’s Guide
Device Configuration dialog - Control Configuration tab
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:

Device Configuration dialog - Control Configuration tab
• 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.
