[RC-100A / RC-100B]


※ RC-100A is not produced currently; it is not sold any longer.


Part Usage

This is a devices to communicate with the robot via IR, ZIGbee, or Bluetooth.

If nothing is mounted the default communications is via IR.

Mount the ZIG-100 to communicate via ZIGbee.

mount the BT-100  to communicate via Bluetooth (RC-100 not supported)


The RC-100 lights green and RC-100A lights blue when mounted with a ZIGbee or Bluetooth module.  


How to Use

  1. Turning the power on  
  2. Turning the power off
  3. Automatic Powersave Mode
  4. Transmitting button-pressed status

How to Set IR Communication Channel

Can set communication channel in between 1 ~8 for controlling by IR wireless communication. To connect the wireless communication, the channel setting of receiver should be the same with that of sender. Following is the method for IR wireless communication channel setting.  (Please refer here to see the channel setting method of controller )


How to Install ZIG-100 / BT-100 Module

  1. Open the cover of the rc-100 and insert the zig-100 module properly.
    You can insert both zig-100 and bt-100 into the RC-100A.)

  2. Insert the module as below so that  the red-circled parts can contact each other.

  3. Press firmly to insert ZIG-100/BT-100 module using fingers or long stick etc.
  4. The following picture shows ZIG-100/BT-100 module is installed completely in RC-100A.
During an impact the zig-100/bt-100 may be dismounted from the rc-100. In this case rc-100 defaults to IR communications.


How to Set Broadcasting Channel

It is possible to set  4 channels with buttons, if the ZIG-100 on RC-100Z was set at Broadcasting Mode (Multi: Multi communication mode).

Channels can be changed if you press the number buttons (1~4) together while MODE buttons are being pressed.  

The red LED will blink as many as the channel no. , when the channel is changed.  


Caution 1 : At initial status, it is of no use to change the channel because  it is automatically set at One: One communication mode, instead of  Multi : Multi communication mode.1

Caution 2 : The ZIG-100 communication can be discontinued for seconds when changing the channels.

Caution 3 : When you take away batteries, the channel will be reset at initial status automatically and you need to reset it.


Remote Control Code Map

Button 5 and 6 are not available under IR control mode.


When you press the buttons on RC-100, corresponding code value of each button will be sent out.



When more than 2 buttons are pressed, the sum of pressed code values will be sent.

EX1)  Button U + Button 3 => Code value of Button U (1) + Code value of Button 3 (64) = Sending Value (65)

EX2)  Button 1 + Button 5 => Code value of Button 1 (16) + Code value of Button 5 (256) = Sending Value (272)


※ There are 128 combination keys usable in IR Mode.

※ There are 512 combinations keys usable in Zigbee Mode.              


Communication Packet

The RC-100 uses the communication packet in the form below


~ represents Inverse (1’s Complement)

Ex) ~0xAA ㅡ> 0x55, ~0xF0 ㅡ> 0x0F


Ex) DATA : 0x1234

Packet : 0xFF 0x55 0x34 0xCB 0x12 0xED


How to Insert Batteries

  1. Open the lid on the backside.

  2. Insert 1 battery. (Please be careful with the terminal)

  3. Insert the other battery.

  4. Press firmly to insert the batteries.


If there are problems with the RC-100A’s Bluetooth or ZigBee and LED flashes try replacing the batteries with new ones.
