MAS7.1 Command Reference
‘XS’ Control Settings (Continued)
Response String:
=XS
settings
Where ‘
settings
’ is a bitmapped parameter:
AS - 0=Master / Slave mode.
1=Asynchronous Mode.
FP
- 0=Disable Front Panel.
1=Front Panel Enabled
IRE - 0=Disable IR Control.
1=Enable IR Control.
IRS - 0=Turn off IR Sensor.
1=Turn on IR Sensor.
IRJ - 0=Turn off IR Jack.
1=Turn on IR Jack.
CSE - 0=Disable CS and CRC-8
1=Append either Checksums or CRC-8 to responses.
CRC- 0=Append Checksums,
1=Append CRC-8’s, to responses.
12V - 0=12V disabled
1=Use IR Jack as 12V On / Off Control
This command uses a bitmapped parameter. See:
.
If the ‘$’ parameter 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 “Transmit Enable Settings”, see:
‘XE’ Transmit Enable 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 MAS7.1 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 sen-
sor (IRS) and enabling IR control (IRE), allows the MAS7.1 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 commands are no lon-
ger 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’ option being
disabled.
