2.3.1 RJ45 FTP cables
For connecting instruments to the FLOW‐BUS you need shielded cables with at least 3 wires (for data only).
Recommended are twisted wire cables for RS485‐communications with 100 or 120 Ohm impedance. All Bronkhorst
FLOW‐BUS cables have also integrated power‐supply wires. For the use in the EL‐FLOW range (non IP‐65) it is best to
use Shielded (+Foiled) Twisted Pair patch‐cables with RJ45 modular jack connectors (8‐pins for data and power‐supply
connections).
