4.4 External Equipment
OPTIC-4 has a full range of external equipment interfaces and control functions, which permit
system integration with GC, autosampler and other equipment like valves or pumps. The
connections are provided on D-type and mini-DIN connectors on the rear panel of the control unit.
The connection pin-outs are specified in Appendix B “Rear Panel Connections”. Instructions for the
connection of OPTIC-4 to the host GC and autosampler are included in the dedicated installation kit
for your GC.
4.5 Connection to Host PC
The OPTIC-4 control unit should be connected to a PC running the Evolution Workstation software.
This software is used to control and configure the system and to define and develop the analytical
methods, which are then started directly from the PC. USB and LAN communication interfaces are
available. OPTIC-4 automatically checks both USB and LAN ports to detect the connection to the host
PC. Note that if OPTIC-4 is connected to a LAN via a switch or a hub, a standard network cable should
be used. If the instrument is connected directly to the PC via a LAN port, a crossed network cable is
required. For remote communication to be established the Evolution Workstation software
communication parameters should match the communication parameters set in the control unit.
The details of the communication interface configuration are described in Chapter 5 “Software
Installation and Configuration”.
4.6 Liner and Column Installation
The ways, in which the column should be installed and the type of the liner required depend upon
the application of the OPTIC-4.
4.6.1 Liner Installation
Normally the inlet is delivered without liner. To install or to change the liner, follow the procedure
below:
1. Cool the inlet to temperature below 40°C.
2. Unscrew the larger knurled nut by hand (top boss clamping nut) that clamps the inlet top
assembly to the inlet body. Lift the top assembly carefully aside. Care should be taken not
to stress the gas lines connected to the top boss and not to break the liner if there is the
one in the inlet.
3. Take out the existing liner with the o-ring in place.
4. Insert the new liner with o-ring.
5. Replace the top assembly and tighten the nut finger-tight. Do not use a spanner or
wrench, as this is likely to damage the inlet.
