A computer specification can be requested from Thermo Fisher
Scientific if required. Most modern PCs are suitable, but they should
ideally incorporate at least one serial port. This functionality can be
provided through a USB-to-serial converter.
Contact the factory regarding compatibility with different versions of
Microsoft® Windows® operating system.
If a permanent PC connection is planned, the most common
configuration, physical space, and a mains power supply are
required. The PC can be local to the instrument or remote depending
on requirements and the area classification of the instrument
location.
The PC is connected to the instrument enclosure via a serial link.
Connection is to the host terminals on the CPU IO PCB in the
bottom left of the enclosure, through the gland plate. Other serial
connections, such as link to DCS, are also made here.

No user electrical connections (power or signal) are made

All electrical connections are to be made to the flameproof
box above the main enclosure (or to additional flameproof
boxes in the case of extended I/O). See
