Introduction

The IR-USB02 is an USB interface which connects mightyZAP linear servo actuator and user's PC via USB port for various setting of servo actuator. Input power needs to be supplied via power socket (Input power should be same as the input voltage of servo motor) and it supports TTL and RS-485 protocol.

• Memory Setting
• Parameter Setting - Reading & Writing
• Error Indicator
• System Reset
• Firmware Update

※ NOTE : IR-USB02 does NOT include USB cable & actuator wire harness.  Use USB Micro B-type(Standard 5pin) cable(for Android smart phone) which supports data transfer(Do not use “Charge only” USB cable) and use the wire harness according to selected communication method between TTL/PWM(3pin connector) and RS-485(4pinconnector) which is included in the actuator package.

[!CAUTION] Proper Power Input!!

• A protection function against reverse power supply was adopted, but make sure correct polarity (+/-) when connect the power (see the back side of PCB)
• Make sure to apply correct input voltage corresponding the voltage user's servo.(7.4V or 12V)

# How to Supply Power to IR-USB02

IR-USB02's power input voltages are 7.4V or 12.1V, so user needs to put proper voltage to the servo according to user's servo input voltage. For 7.4V version mightyZAP, put 7.4V input power to IR-USB02 and for 12.1V version of mightyZAP, put 12.1V input power to IR-USB02. This means that user CANNOT use different voltage versions of mightyZAP at the same time through IR-USB02.

CAUTION! Proper Power Input!

• Make sure polarity (+/-) when connect the power (see the back side of PCB).
• Make sure to apply correct input voltage corresponding the voltage user's servo.(7.4V or 12V)
