[ 4 ] Cautions for TMS Scanner Communication
•
The upstream and downstream cables form a loop in TMS scanner communication.
Star connection using a hub as in the Ethernet is not adopted. In TMS scanner communication,
each loop is called a channel.
Downstream
Upstream
Channel 1 (S1-01)
Channel 2 (S1-02)
