2. Installation
When the master receives the logic token, it inquires data from its slaves. After all
communications are completed, the master passes the token to another master. In this way,
the master can only communicate with its slaves while it is holding the token. The slaves
respond to only the inquiry from the master. No slave can output any messages.

Strip approx. 47.5 mm of the cable covering with extra
care so that you do not scratch on braided shield
underneath.
Do not strip the cable covering more than necessary.
Excess stripping may cause short-circuit and/or make
the cable more sensitive to noise.
Carefully expand meshes of the braided shield and fold
back the shield over the cable covering. Cut off the
shield at approx. 10 mm from the stripped side of the
cable covering.
Strip the covering of the signal wire as shown in the
figure.
Insert the signal wires into the terminal block on the connector and secure the signal
wires. Carefully connect the same signal wire to the same terminal on both ends.
To prevent faulty wiring, make a rule of connection. For instance, connect the green
signal wire to the A1/A2 terminal and the red signal wire to the B1/B2 terminal.
