3.6 The i-BUS Connector
Please Note
• The i-BUS uses RS422 lev els on its RX and TX Pins, although Ethernet jack/plugs mechanically
fit, the device is not Ethernet compatible.
• As the TxD/RxD cr ossing is done by the pinout of the connectors, simple str aight cabling can be
used.
• If devices are powered by the RJ45 cabling of th e i-BUS, wire gauge must be at least A WG24
(0.25 mm²)
