Calculating Total Distance when Using Different Cables
When using 10BASE-2 and 10BASE-5 cables, the total length of the cables must satisfy the
following formula:
Length of 10BASE-2 cable + Length of 10BASE-5 cable x 0.4 ≤ 185
Example: If Length of 10BASE-2 cable = 5 m; Length of 10BASE-5 cable= 450 m
Total Distance=5 m + 450 m x 0.4 = 185 m
Since the above lengths of cables are satisfying the formula, the total distance of V net is
within the limit.

Attaching Clamp Filters (Ferrite Cores)
After completing the V net cable (10BASE-5 cable) connection, attach the clamp filters (inclu-
ded with the product) to the V net cables over the cable sheath in order to improve noise iso-
lation.
IMPORTANT
The clamp filter case is made of plastic.
The clamp filter case may crack when opened and closed at a sub-zero temperature (in centi-
grade) or following a mechanical shock such as a fall. Maintain the applicable operating tem-
perature range and storage temperature range for each device.
