timing information as specified by HR protocol. The UHBX-8X currently cannot
learn the detailed timing, so a model HR-4P with a detector cable
(demodulated type 2) will be required for learning these codes. The learned
codes can be cut from the HR-4P GUI, and used as data for the IS9 command.
The IS9<cr> command is followed by a string of hex bytes to be sent out. The
user has up to 5 seconds to enter each hex byte from 0x00 to 0xFF.
When all Hex bytes are entered, two special bytes (0x17 followed by 0x0D,
called terminal characters) must be appended to the end of the data.
For further info and an example please refer to IR supplement available on
line.
Response: OK <cr>
Command: CFn <cr> Stands for IR Carrier Frequency
N 1 2 3 4
IR Freq 36KHz 38KHz 40KHz 56KHz
Factory default is 38 KHz. This command should be used prior to issuing IS9
command if your IR signal is something other than 38 KHz. All infra red
remote controls have a modulation (or carrier) frequency and the vast
majority operate at 38KHz.
Response: CFn <cr>
Command: FD <cr> Stands for Restore Factory Default
This command will restore the unit to factory default condition, use with care.
Response: FD <cr>
This indicates that the command completed successfully
Command: FW <cr> Stands for Query Firmware Version
This command will report the firmware version in the unit. If the firmware is
out of date, you can update the firmware using the USB port on the UHBX-8X.
Please see the Windows GUI Guide for further instructions.
Response: FWx.x <cr>
x.x is the version of the firmware in the device.
