1. If the LED remains off when a key is
pressed, users should check the
battery condition.
2. If problems are unable to be
resolved using the above methods,
consult the “Technical Support” on
the Best Module Official Website.

Functional Description

1. The product operating frequency is 433.92MHz.
2. The key de-bounce time is 40ms.
3. The corresponding data packet will be
transmitted more than twice each time a key
press is acknowledged.
4. The LED will be illuminated during data
transmitting, an indication which can be used to
check the product operation status.
5. A PCB antenna is used thus eliminating the need
for an external antenna.
6. This product can be matched to several modules
of the same type It can therefore control multiple
modules at the same time when the keys are
pressed.
7. The module Master MCU, the BC68F2130,
includes integrated programs, eliminating the
need for user programming.
8. Refer to the “Appendix 2: HT OOK demo board
package format” for the RF transmitting package
contents.

• This product uses a custom signal transmitting
protocol, and should therefore be used together
with an RF wireless receiving module, which
needs to be purchased separately. Refer to the
“Appendix 1: Product System Diagram” for more
detailed information.
• The Master MCU, a BC68F2130, contains 2K of
program memory. Another 4-key 433MHz RF
remote controller, the BCR-68F2123-X01, can
alternatively be used if a more cost effective
solution is required. Using the BC68F2123 Master
MCU, which contains 1K of memory, is more
suitable for simpler functional requirements.

Insert Battery
Insert a CR2032 battery. Note that the MCU will enter
the power down mode if there are no operations.
5
Check the corresponding signals
Note: The key should be pressed and held for at least 40ms to avoid
the system ignoring any key press actions.
Press any key to transmit the corresponding signal,
the LED indicator will be illuminated simultaneously.
6
Power Down Mode
The signal transmission will stop and the LED indicator
will be off after the key is released. The product will
then enter the power down mode automatically.

Name: 4-key 433MHz RF wireless remote controller
Model: BCR-68F2130-X01
This product uses a custom signal transmitting protocol, and
should therefor be used together with the corresponding
433MHz RF receiving module, namely the BCM-68F2420-
C01/ BCM-2401-C03.

End code is used to separate the sequent two code words.
C. End code: 2λhigh + 2λlow
Leading code: Repeating 1λhigh and 1λlow for 8 times.
A. Leading Code + Start code

For TX demo boards / remote controllers, their addresses are pre-programmed in the MCU program
ROM. Users do not need to specify the address.
For RX demo boards, they have to be paired with a TX first before being used. The paring process
allows the RX recognize the TX and memorize TX’s address in its non-volatile memory.
CRC=X^8+X^5+X^4+1 ,

The total length for a code word is 200us x (16+6+96+32+32+4) = 37.2ms
The “code word” is a group of code bits used in OOK wireless communication.
This document describes the code word format used in HT OOK demo boards.
A code word consists of leading code, start code, address, data, CRC and end code.
Each fields are composed with several symbols. The symbol rate is set as 5Kbps.
Each symbol (λ) in table below is 200us.
