5.1 Simultaneous Key Press (RC)
If more than one key-press is detected, the remote control will stop sending IR/RF code.
Example:
i. When Key 1 is pressed, Key 1 code is transmitted. Pressing Key 2, with Key 1 still pressed, RC will
stop transmitting Key 1 code. Then, releasing Key 2, with Key 1 still pressed, Key 1 code will be
transmitted again.
ii. When Key 1 is pressed, Key 1 code is transmitted. Pressing Key 2, with Key 1 still pressed, RC will
stop transmitting Key 1 code. Then, releasing Key 1, with Key 2 still pressed, Key 2 code will be
transmitted.
5.2 Simultaneous Key Press (Keyboard)
The remote control supports multiple key-presses but only limited keys are able to do so. When two
or more keyboard keys that do not support simultaneous press are pressed simultaneously, the
remote will not send any code. When only one key remains pressed, the remote will restart and send
the code of this key as per normal.
Workable 2-keys simultaneous key-presses are:
-
CAPS
with any alphabets (uppercase of the alphabets
)
-
FN
with Blue option keys (numbers and symbols, etc.)
-
Alt Gr
with Orange option keys (special characters and other symbols, etc.)
5.3 Consecutive Key Press (Keyboard)
When
FN
key is pressed or still pressed, the RC will not transmit code or do any action. After release
and then press any keys that have an alternate function on the same key, e.g. Q key shares the same
as numeric „1
‟
key, the RC will transmit numeric „1
‟
code.
E.g.
FN
key + Q key = Numeric „1
‟
key is transmitted
FN
key + A key = Symbol „?
‟
key is transmitted
The same is true for
CAPS
and
Alt Gr
keys. For example, after release of the
CAPS
key, an alphabet
key is pressed; the RC will transmit the uppercase letter of the particular key.
5.4 LED Indicator
Blinking Definition
Fast Blink (IR Learn): approximately 50ms ON, then OFF.
Slow Blink (IR Learn): approximately 500ms ON, then OFF.
Short Blink: approximately 10ms ON, then OFF.
Long Blink: approximately 500ms ON, 500ms OFF.
5.5 Stuck Key Timeout
Stuck Key means that a button has been pressed for a very long time in normal operating mode.
To preserve battery power, the remote will stop sending code (
IR and RF
) and shut down at about
30
seconds after the last key transition to consume minimal power. After all keys are released, the
remote resumes normal operation
.
Exceptions: Mouse Left Click, navigation keys and “OK” key will not have Stuck Key timeout in normal
operation mode. In setup/programming mode, these keys will have stuck key timeout.
Typical Stuck Key timeout is /- 20% tolerance, except for IR with exceptional long repeat
timings or RF long latency.
The application will have some mechanism to stop mouse data transmission to save battery life.
In TV Control Setup, there are situations where a key is allowed to be pressed for longer than the
Stuck Key timeout.
