LED Lighting connector to 100 percent. When held for a long press, the lighting
control sensor will elevate the lighting level for as long as the contact is closed, or
until it reaches 100 percent.
An IR, or infrared transmission, is created by sending an IR timing pattern to the
Netkit. This pattern is a collection of <on> and <off> states modulated with a
carrier frequency ( ƒ ) which is present during the <on> state. A carrier frequency
is typically between 35 to 45 KHz with some equipment manufacturers using as
high as 500 KHz. The length of time for an <on> or <off> state is calculated
in units of the carrier frequency period. For example, an <off> value of 24
modulated at 40 KHz produces an <off> state of 600μS, as calculated below.
A period is 1 /ƒ or 1/40000 or .000025 seconds or 25μS, and a value of 24
periods is 600μS
IR timing patterns typically have a long, final <off> value (or rest state) to ensure
the next IR command is interpreted as a separate IR transmission.
5.3.5 IR Structure
Control of IR devices is accomplished through use of the sendir command. Since
IR commands may take up to 100mS to complete, the Netkit provides a completeir
acknowledgment to indicate when it is ready to accept the next IR command for the
connector in use.
Sendir
Sent to Netkit:
sendir,<connectoraddress>,<ID>,<frequency>,<repeat>,<offset>,<on1>,<o
ff1>,<on2>,<off2>,….,<onN>,<offN> (where N is less than 260 or a total of
520 numbers)
where: <connectoraddress> is as defined in section 1.
<ID> is |0|1|2|…|65535| (1) (for the completeir response, see below)
<frequency> is |15000|15001|….|500000| (in hertz)
<repeat> is |1|2|….|50| (2) (the IR command is sent <repeat> times)
<offset> is |1|3|5|….|383| (3) (used if <repeat> is greater than 1, see below)
<on1> is |1|2|…|65635| (4) (number of pulses)
<off1> is |1|2|…|65635| (4) (absence of pulse periods of the carrier frequency)
