Technical Interface Overview
The YCB141-M002 is a high-precision coaxial interconnect cable designed for Yokogawa V net communication systems. It supports 10BASE-2 (Thin Ethernet) protocol implementations used in legacy and high-availability CENTUM distributed control architectures.
This cable provides the physical communication path between Field Control Stations (FCS) and bus couplers, ensuring deterministic and low-latency control data transmission. The 2-meter (M002) length is typically used for cross-cabinet or adjacent rack connections when shorter cables are insufficient.

Technical FAQ
Can I use a standard 50 Ω coaxial cable?
No. Although impedance may match, YCB141 cables use specialized shielding and connectors tested for V net communication reliability. Non-certified cables may cause communication instability.
Is there a maximum daisy-chain length?
Yes. A V net segment is typically limited to about 185 meters. Each connection introduces slight signal loss, so unnecessary junctions should be avoided.
Does it support Vnet/IP?
No. The YCB141 series is designed for coaxial V net networks only. Vnet/IP systems require Ethernet-based cables such as the YCB146 series.
