Connection and communication
with devices
Connecting the bicycle to a device allows you to configure the system, update firmware, and
more.
E-TUBE PROJECT is needed to change the setting of the SHIMANO STEPS and to update
firmware.
Download E-TUBE PROJECT from our support website (https://e-tubeproject.shimano.com).
For information on how to install E-TUBE PROJECT, check the support website.
This manual describes how to connect to the PC version of E-TUBE PROJECT. Wireless
connections may also be possible, depending on the model. Refer to the user's manual.
TECH TIPS
• When a connection is established between E-TUBE PROJECT and the cycle computer or
all STEPS components, the STEPS logo or E-TUBE is displayed on the screen of the cycle
computer.
• The PC linkage device is needed to connect SHIMANO STEPS to a PC. Junction [B] will
be needed in the following situations:
– When there are no free E-TUBE ports on the cycle computer (for example, if using an
electronic gear shifter)
– When connecting the switch unit by itself to the PC
• When connecting a device compatible with the EW-SD300 to the PC linkage device, use
a conversion adapter (EW-AD305) to connect the wire to the EW-SD50.
• Firmware is subject to change without notice.
• PC connection and communication are not possible when charging the battery. Do not
connect to a device while the battery is being charged.
