FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)

INTRODUCTION
The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting
equipment and contains several parts, referred to as series. The IEC 62386-1xx series includes
the basic specifications. IEC 62386-101 contains general requirements for system components,
IEC 62386-102 extends this information with general requirements for control gear and
IEC 62386-103 extends it further with general requirements for control devices. IEC 62386-104
and IEC 62386-105 can be applied to control gear or control devices. IEC 62386-104 gives
requirements for wireless and alternative wired system components. IEC 62386-105 describes
firmware transfer. IEC 62386-150 gives requirements for an auxiliary power supply which can
be stand-alone, or built into control gear or control devices.
The IEC 62386-2xx series extends the general requirements for control gear with lamp specific
extensions (mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear
specific features.
The IEC 62386-3xx series extends the general requirements for control devices with input
device specific extensions describing the instance types as well as some common features that
can be combined with multiple instance types.
This first edition of IEC 62386-305 is intended to be used in conjunction with IEC 62386-101,
and IEC 62386-103. The division into separately published parts provides for ease of future
amendments and revisions. Additional requirements will be added as and when a need for them
is recognized.
The setup of the standards is graphically represented in Figure 1 below.

Figure 1 – IEC 62386 graphical overview
When this part of IEC 62386 refers to any of the clauses of the IEC 62386‑1xx series, the extent
to which such a clause is applicable is specified. The other parts also include additional
requirements, as necessary.
All numbers used in this document are decimal numbers unless otherwise noted. Hexadecimal
numbers are given in the format 0xVV, where VV is the value. Binary numbers are given in the
format XXXXXXXXb or in the format XXXX XXXX, where X is 0 or 1; "x" in binary numbers

– 10 – IEC 62386-305:2023 © IEC 2023
9.3 Input signal and value
9.3.1 General
The "inputValue" shall indicate the value measured by the sensor, encoded as a 24-bit red-
green-blue (RGB) value. The red, green and blue components of "inputValue" shall be a strictly
monotonic function of the corresponding measured red, green and blue values.
After receiver start-up, it can take the sensor some time before valid colour measurements are
obtained. During this time, QUERY INPUT VALUE and QUERY INPUT VALUE LATCH shall
reply as if "inputValue" is MASK. After the first valid colour measurement is obtained,
"inputValue" shall not be MASK, except in the case of physical sensor failure (see 9.6.1).
The input "resolution" shall be equal to 24.
NOTE A "resolution" of 24 implies that "inputValue" is a three-byte value.
9.3.2 Input value encoding
The "inputValue" shall be encoded as shown in Table 1.
Table 1 – Input value encoding
Bits Description Value Alias
[7:0] Red Observed red level [0, 254] "rValue"
[15:8] Green Observed green level [0, 254] "gValue"

9.4 Events
9.4.1 Priority use
9.4.1.1 General
The default "eventPriority" is defined in Table 9.
NOTE Application controllers can ensure this instance leaves higher priority timeslots on the bus by setting the
instance’s "eventPriority" to a priority greater than 2.
9.4.1.2 Periodic events
The periodic "INPUT NOTIFICATION" message triggered by the report timer that reports the
colour value event shall always be sent with priority 5.
9.4.2 Bus usage
9.4.2.1 Instance level
Multiple events from an instance shall not be sent in the same transaction. Also, there is a
configurable delay T that shall be taken into account. See 9.5.2 for more information.

NOTE 1 Due to the 10-bit size of the event message information, the resulting colour report provides only 512
colour combinations and depending on the set-point of the hysteresis, duplicate event messages are possible.
NOTE 2 Application controllers can query the "inputValue" to obtain a higher resolution representation of the
measurement.
9.4.4 Event configuration
Events shall be enabled or disabled according to the value of "eventFilter", as specified in
Table 4. For this instance type, "eventFilter" shall be reduced to one byte. No configurations of
"eventFilter" shall prevent the periodic "INPUT NOTIFICATION" message triggered by the report
timer (9.5.1).
NOTE Inhibiting events increases the effective bus bandwidth availability.

9.4.5 Event generation
The colour report event is a truncated report of the "inputValue". To limit the number of events
generated on small level changes, a hysteresis band is introduced. The height of the hysteresis
band ("hysteresisBand") determines the minimum change of the colour values that shall generate
an event according to the following calculations. As the "inputValue" is an array of the three
colour values, "rValue", "gValue" and "bValue", the hysteresis is based on the summed absolute
change of each colour value.
"absoluteChange" = |"rValue" − "rLast"| + |"gValue" − "gLast"| + |"bValue" − "bLast"|
The colour report event shall be generated
• each time "absoluteChange" becomes greater than "hysteresisBand", or
• after a timeout of T since the previous colour event, irrespective of the actual
report
"inputValue".
The power on value of "hysteresisBand" is 0, such that the first non-zero value of "inputValue"
shall cause the colour report event to be generated according to the first condition shown above.
See 9.5.4 for details.
In case a new event occurs before the current event has been sent, the new event shall replace
the current event. This can be caused, for example, by bus unavailability or the deadtime timer.
Each time the colour report event is sent because "absoluteChange" is greater than
"hysteresisBand", then the values of "rLast", "gLast", "bLast" and "hysteresisBand" shall be
recalculated as follows:
• "hysteresisBand" is calculated as the maximum of:
– "hysteresis" percentage of ("rValue" + "gValue" + "bValue"), and
– "hysteresisMin";
• "rLast" = "rValue";
• "gLast" = "gValue";
• "bLast" = "bValue".
EXAMPLE with "hysteresis" of 10 %:
At power-on, "hysteresisBand" is 0. Measurement 1 gives colour values of [R = 70, G = 110, B = 120]. A colour report
event is generated as "absoluteChange" > "hysteresisBand". "hysteresisBand" is set to 30 ((70 + 110 + 120) × 10 %).
"rLast" = 70, "gLast" = 110, "bLast" = 120.
Measurement 2 gives colour values of [R = 80, G = 106, B = 125]. "absoluteChange"
= |80 − 70| + |106 − 110| + |125 − 120| = 19. A colour report event is not generated as
"absoluteChange" ≤ "hysteresisBand". "hysteresisBand", "rLast", "gLast" and "bLast" are unchanged.
Measurement 3 gives colour values of [R = 85, G = 98, B = 130]. "absoluteChange"
= |85 − 70| + |98 − 110| + |130 − 120| = 37. A colour report event is generated as
"absoluteChange" > "hysteresisBand". "hysteresisBand" is set to 31 ((85 + 98 + 130) × 10 %). "rLast" = 85, "gLast" = 98,
"bLast" = 130.
9.5 Configuring the input device
9.5.1 Using the report timer
If the report timer is set, it shall generate a 'repeat' trigger every T even if the "inputValue"
report
has not changed. The report timer shall be restarted every time an event is sent.

The report timer shall be started,
• at power-on: if enabled, immediately after both the receiver has started up and the colour
measurement has become valid, with the time to the first trigger recommended to be
shortened to a random time between 0 s and T s;
report
• otherwise immediately after enablement.
This implies that the first "INPUT NOTIFICATION" message due to the report timer is sent at a
maximum time of T after starting. This may be delayed by other "INPUT NOTIFICATION"
report
messages, or by bus availability.
9.5.2 Using the deadtime timer
If the deadtime timer is set, the instance shall not send out an event until the deadtime timer
has expired. The deadtime timer shall be restarted every time an event is sent.
9.5.3 Setting the timers
The deadtime and report timers shall be programmable as indicated in Table 5.
For each timer, a fixed minimum duration and a fixed increment in duration are given. The
application controller can set the desired actual timer duration by setting the number of
increments to a value in the range [0, 255]. The resulting time shall be strictly monotonic
according to the following formula:
Time = T · multiplier
incr
Only on (re-)starting a timer the actual time shall be calculated based on the corresponding
variable. This implies that the times only change after any running timer has been cancelled or
expired. The tolerance on the time shall be ±5 %.

The input device shall expose the following operations to set and observe the timer multipliers:
• "SET REPORT TIMER (DTR0)", "QUERY REPORT TIMER" to set or query "tReport";
• "SET DEADTIME TIMER (DTR0)", "QUERY DEADTIME TIMER" to set or query "tDeadtime".
"SET REPORT TIMER (DTR0)" shall set "tReport" depending on "DTR0". If "tReport" is set to 0,
the report timer shall be disabled immediately.
"SET DEADTIME TIMER (DTR0)" shall set "tDeadtime" depending on "DTR0". If "tDeadtime" is
set to 0, the deadtime timer shall be disabled immediately, but shall not affect T until the
report
report timer is (re-)started.
If T < T , T shall be T (independent of the value of "tReport").

9.5.4 Setting the hysteresis
The height of the hysteresis band, "hysteresisBand", is calculated according to 9.4.5 using the
percentage given by "hysteresis" with the minimum height given by "hysteresisMin". The input
device shall support a hysteresis up to 25 %. A value of zero for "hysteresis" shall lead to colour
events based on T only. The input device shall expose the following operations to set and
report
observe the values of "hysteresis" and "hysteresisMin":
• "SET HYSTERESIS (DTR0)", "QUERY HYSTERESIS" to set or query "hysteresis".
"SET HYSTERESIS (DTR0)" shall set "hysteresis" in 1 % steps depending on the "DTR0" value
as follows:
• if "DTR0" > 25: no change;
• in all other cases: "DTR0".
Since a hysteresis in percent would require a growing resolution in case the "inputValue" is low,
the minimum value for the hysteresis is physically limited. To avoid unwanted events at low
sensor values, the minimum value for the hysteresis can also be set as an absolute value
"hysteresisMin":
• "SET HYSTERESIS MIN (DTR0)", "QUERY HYSTERESIS MIN" to set or query
"hysteresisMin".
"SET HYSTERESIS MIN (DTR0)" shall set "hysteresisMin" to "DTR0".
9.5.5 Manual configuration
If IEC 62386-333 is implemented, the instance level variables according to Table 6 may be
manually configured. "QUERY MANUAL CONFIGURATION CAPABILITY 3xx" (see
IEC 62386-333) shall return the byte as defined in Table 6:
Table 6 – "manualCapabilityInstance3xx" values
Bit Description Value
0 Manual configuration of "tReport" supported "1" = "Yes"
1 Manual configuration of "tDeadtime" supported "1" = "Yes"
2 Manual configuration of "hysteresis" supported "1" = "Yes"
3 Manual configuration of "hysteresisMin" supported "1" = "Yes"
4 Reserved "0"
5 Reserved "0"
6 Reserved "0"
7 Reserved "0"
9.6 Exception handling
9.6.1 Physical sensor failure
If a physical sensor failure is detected, the instance shall set "instanceError" to TRUE, from the
moment the failure is detected until the failure is resolved. While the error is detected, no further
events shall be sent and "inputValue" shall be set to MASK as defined in 9.3.
9.6.2 Manufacturer-specific errors
If a manufacturer-specific error is detected, the instance shall set "instanceError" to TRUE, from
the moment the error occurs until the error is gone.

9.6.3 Error value
"instanceError" can be observed via "QUERY INSTANCE STATUS".
While "instanceError" is set, "QUERY INSTANCE ERROR" shall return "instanceErrorByte"
according to Table 7:
Table 7 – "instanceErrorByte" values
Bit Description Value
0 Physical sensor failure? "1" = "Yes"
1 Reserved "0"
2 Reserved "0"
3 Reserved "0"
4 Manufacturer-specific error 1? "1" = "Yes"
5 Manufacturer-specific error 2? "1" = "Yes"
6 Manufacturer-specific error 3? "1" = "Yes"
7 Manufacturer-specific error 4? "1" = "Yes"

If used, the meaning of bits [7:4] of "instanceErrorByte" shall be documented in the manual. The
impact on event generation shall also be documented.
