BT-110/110A

Introduction

Note BT-100/110A is discontinued.

BT-100/110A are Bluetooth modules that communicate via UART. The BT-100 and BT-110A only differ on mounting interface. The connectable parts are as follows: (Please refer to the explanation pages on each part on how to install.)

Warning Followings are NOT compatible with BT-110A Set

  1. Remote: RC-100 (When affixing on wireless module, green LED lights on)
  2. Controller: CM-100, CM-5, CM-2+

The BT-100/110A are sold together as a set and set with factory default settings so there’s no need to do additional work in settings during mounting. (Please be careful not to lose one of the set.)
1:1 communication with BT-100/110A only.

Example

Caution Connect the modules while power is off. Connecting while power is on could result in malfunction.
