MAS7.1 Component Video Switch
MAS7.1 Component Video Switch
Rear Panel IR Control
The rear panel jack labeled "IR-IN" allows the MAS7.1 to be con-
trolled by hardwired IR controllers.
To enable/disable the rear panel IR jack , see the section entitled:
"Control Functions"
.
The IR signal can be either modulated or unmodulated with a modu-
lation frequenc y ranging from 0KHz to 500KHz.
30KHz to 500KHz
3V to 15V
0V
MODULATED SIGNAL
UNMODULATED SIGNAL
3V to 15V
0V
And uses a standard 1/" (.5mm) mini-plug:

TIP
The voltage level is bi- directional and fully opto -isolated. I t doesn' t
matter which way you connect your voltage source across the tip
and sleeve of the connector. Neither side of the IR-jack is grounded,
and either the tip or the sleeve can be connected to ground without
the possibility of ground loops.
The signal voltage can range from +V to +15V or from -V to -15V.
The IR jack recognizes the same IR codes as the front panel IR sen-
sor. If the MAS7.1 is taught new codes, these new codes will become
the new codes recognized by the IR jack .
Note: The IR control jack option is mutually exclusive with 12V
On/Off control option (they use the same jack!).Only one
of these options can be enabled at a time.
12V On / Off Control
The rear panel jack labeled "IR-IN", when not being used as an IR
Jack , can allow the MAS7.1 to be turned on and off using a 12V con-
trol voltage.
To enable/disable the 12V On/O ff control functions, see the section
entitled:
"Control Functions"
.
By enabling the 12V On/O ff control option, the MAS7.1 will turn
itself on whenever the voltage going into the IR-IN jack goes from
LOW to HIGH, and it will turn itself off whenever the voltage goes
from HIGH to LOW.
The MAS7.1 only looks at transitions on the IR-IN jack . For instance if
it detects a LOW to HIGH transition it will turn itself on. The user can
then use the power switch to turn off the MAS7.1. After which the
voltage on the IR-IN jack must go from HIGH to LOW and then back
to HIGH, to once again turn on the MAS7.1.
The voltage level is bi- directional and fully opto -isolated. I t doesn' t
matter which way you connect your voltage source across the tip
and sleeve of the connector. Neither side of the IR-jack is grounded,
and either the tip or the sleeve can be connected to ground without
the possibility of ground loops.
A HIGH level is any voltage from +V to +15V, or any voltage from
-V to -15V.
A LOW level is any voltage between -0.2V and +0.2V.
All levels between these two levels is undefined.
