Omni FTIR Multi Gas CEMS Instruction Manual

Thermo Fisher Scientific

You can connect to the FTIR via Serial or Ethernet communications. Refer
to

Figure C–1

and the “Installation” chapter. For Modbus over Ethernet,

use TCP port 502 by default (user selectable).

The terminal block shown in

Figure C–1

provides a convenient way to

connect devices to the instrument.

Note

Consult with a network engineer or system administrator for

information about making the appropriate Ethernet connection for your
application.
