Control Settings
Turn on and off operational modes of the HDMI5.
This command allows control over the following:
•
Select the Master / Slave or Asynchronous modes of operations.
•
Enable / Disable the front panel switches.
•
Enable / Disable the IR control.
•
Enable / Disable the IR jack.
•
Enable / Disable appending Checksums or CRC-8's to responses.
•
If enabled, choose whether Checksums or CRC-8's will be appended to responses.
XS settings
Set the control bits to 'settings'
XS +settings
Set bits indicated in 'settings' to 1.
XS -settings
Reset bits indicated in 'settings' to 0.
XS settings,$
Set the control bits to 'settings', save in EEPROM.
XS +settings,$
Set bits indicated in 'settings' to 1, save in EEPROM.

The '$' parameter is a "Backup Control Settings" flag. If it exists, then the current settings will
be backed up in EEPROM, and will remain unchanged through a power failure. Backing up the
"Control Settings" will also backup the "Extended Control Settings".
The IR control (IRE) and the IR jack (IRS), work differently when disabled. Disabling IR control,
by setting the 'IRE' bit to zero, keeps the HDMI5 from responding to any IR codes, however the
front panel sensor remains operational and any codes received can still be queried for by using
the "IR ?" command. Disabling the IR sensor (IRS) and enabling IR control (IRE), allows the
HDMI5 to respond to IR signals through the IR jack, any signal received by the IR sensor will be
ignored.
Disabling the IR jack, by setting the 'IRJ' bit to zero, completely disables the IR jack. IR com-
mands are no longer be received through the IR jack if the 'IRJ' bit has been set to zero.
The 'IRJ' flag and '12V' are mutually exclusive. Any attempt to set them both will result in the
'12V' being disabled.
