○ The figure below shows the example of the case where secondary stations 1–3 (3 stations) will be connected to
the primary station.
◇ For cables ①-③, use the cable with the same characteristic impedance.
・Connect secondary stations 1-3 as slave, as shown in the figure.
Use the cable with the same characteristic impedance for the connection between secondary stations as
well.
◇ Attach the terminator to both the primary station ① and the farthest secondary station ② (secondary
station 3).
◇ Choose the terminator of which [Characteristic impedance of cables ①-③] ＝ [Resistance of ①] =
[Resistance of ②].
・Also, use the cable with characteristic impedance where [Resistance of ①]//[Resistance of ②] (parallel
combined resistance) is 75Ω or higher.
