Port/Communication
• Port A (Standard)
• RS-232
• RS-485 Half Duplex
• RS-485 ( 2-wire communi-
cation on Port A.)
Ethernet
(1) RS-485 2-wire connections use TX+ and TX - on the CPU Module
(2) Denotes auto-detected protocols
(3) Denotes auto-detected protocols
(4) Denotes auto-detected protocols
(5) Denotes auto-detected protocols
NOTICE
If not using Ethernet, a full duplex serial connection is necessary for Daniel MeterLink
communicate with a Daniel 3410 Series Ultrasonic Flow Meter.
