Chapter 2. WIRING
An example of connection methods in such a case is shown below.
• Connect terminating resistors of 150Ω±5%, 1/2W min. at each end of the trans-
mission line.
• Terminal block is required for the CMQ-V series because of the connector type
connection.
• The cable to the terminal block from the CMQ-V series must be as short as pos-
sible.
• The FG grounding must not be made at the both shielded wire ends but only at
one location.
• Yamatake’s CMC10L001A000 can be used as a converter of the host station.
Handling Precautions
Be sure to connect SG terminals each other. Failure to do so might cause
unstable communications.
