M400E Ozone Analyzer Operator’s Manual Optional Hardware and Software
5.7.3. ETHERNET (OPT 63)
The ETHERNET option allows the analyzer to be connected to any Ethernet local area network (LAN) running
TCP/IP. The local area network must have routers capable of operating at 10BaseT. If Internet access is
available through the LAN, this option also allows communication with the instrument over the public Internet.
Maximum communication speed is limited by the RS-232 port to 115.2 kBaud.
When installed, this option is electronically connected to the instrument’s COM2 serial port making that port no
longer available for RS-232/RS-485 communications.
The option consists of a Teledyne Instruments designed Ethernet card (see figures below), and a 7-foot long
CAT-5 network cable, terminated at both ends with standard RJ-45 connectors.
